Description

Technical Field

[0001] The present disclosure generally relates to the field of medical device separation, and more particularly to a method for separating and combining medical devices. Background Art

[0002] In the daily work process of the hospital, medical staff often need to combine disposable medical equipment and reusable medical equipment for use, and after use, they need to separate the disposable medical equipment from the reusable medical equipment and replace them with new disposable medical equipment, and then recombine the new disposable medical equipment with the reusable medical equipment for continued use, so the operations of separating and combining medical equipment need to be performed frequently.

[0003] Currently, medical personnel mainly separate and combine medical devices by directly contacting reusable medical devices or by contacting disposable medical devices and reusable medical devices at the same time.

[0004] Problems with existing separation and combination methods include: many operating steps, long time, and low work efficiency; they are prone to infection among medical staff or between patients, and contamination of reusable medical devices by disposable medical devices; they have high requirements for subsequent disinfection operations, increase the frequency of disinfection of reusable parts, reduce utilization efficiency, and increase the maintenance cost of reusable medical devices. Summary of the invention

[0005] The present disclosure is proposed in view of the above-mentioned situation, and its purpose is to provide a method for separating and combining medical equipment that can improve work efficiency and reduce nosocomial infection.

[0006] To this end, the present disclosure provides a method for separating and combining medical equipment, which is a method for separating and combining the medical equipment using a separation and combination device, wherein the medical equipment includes a separation piece and a fixing piece, the separation piece is combined with the fixing piece along a combination direction or separated from the fixing piece along a separation direction, and the combination direction is opposite to the separation direction, and is characterized in that the method includes: fixing the fixing piece to the separation and combination device; replacing the separation piece; and separating the fixing piece from the separation and combination device.

[0007] In the present disclosure, medical staff can operate the separating piece to fix or separate the fixing piece and the separating and combining device in the medical device. After the fixing piece and the separating and combining device are fixed, the separating piece can be replaced. When replacing the separating piece, only the separating piece can be touched without touching the fixing piece. In this way, work efficiency can be improved and hospital infection can be reduced.

[0008] In addition, in the method involved in the present disclosure, optionally, the separation and combination device is configured to have magnetism when powered on and lose magnetism after power is disconnected; when the separation and combination device has magnetism, the magnetic attraction between the separation and combination device and the fixing part is greater than the force that separates the separation part from the fixing part and fixes the fixing part to the separation and combination device; when the separation and combination device loses magnetism, the magnetic attraction between the separation and combination device and the fixing part is less than the force that separates the separation part from the fixing part and separates the fixing part from the separation and combination device. In this case, since the medical device can be formed by a separation part and a fixing part through a simple snap-on combination, the separation and combination device has magnetism after being powered on, and the fixing part and the separation and combination device can be fixed by magnetic attraction; when the separation part needs to be replaced, the separation and combination device can keep the fixing part fixed on the separation and combination device by a magnetic attraction force greater than the force that separates the separation part from the fixing part; the separation and combination device loses its magnetism after power is cut off, and at this time the magnetic attraction force between the fixing part and the separation and combination device can be made smaller than the force that separates the separation part from the fixing part, and when the fixing part is separated from the separation and combination device, the separation part and the fixing part can be kept in a combined state.

[0009] In addition, in the method disclosed herein, optionally, the fixing member and the splitting and combining device are matched in a spiral manner, the fixing member is screwed into the splitting and combining device so that the fixing member and the splitting and combining device are fixed in the direction of the combination direction and the separation direction, and the fixing member is screwed out of the splitting and combining device so that the fixing member is separated from the splitting and combining device. In this case, since the fixing member and the splitting and combining device are matched and fixed in a spiral manner, when the separation member needs to be replaced in the combination direction and the separation direction, the fixing member can be fixed to the splitting and combining device more firmly, so that the fixing member and the splitting and combining device can maintain a more stable state during the replacement of the separation member.

[0010] In addition, in the method disclosed herein, optionally, the fixing member can be rotatably movable on the separation device, and when the fixing member rotates a first predetermined angle relative to the separation device, the fixing member and the separation device are fixed in the direction of the combination direction and the separation direction, and when the fixing member rotates a second predetermined angle relative to the separation device, the fixing member is separated from the separation device. In this case, since the fixing member and the separation device are fixed or separated by rotating a predetermined angle, when the separation member needs to be replaced in the combination direction and the separation direction, the fixing member can be fixed to the separation device more firmly, so that the fixing member and the separation device can maintain a relatively stable state during the replacement of the separation member.

[0011] In addition, in the method involved in the present disclosure, optionally, the fixing member can slide into the splitting and combining device, and when the fixing member slides into the splitting and combining device, the fixing member and the splitting and combining device are fixed in the direction of the combination direction and the separation direction, and when the fixing member slides out of the splitting and combining device, the fixing member and the splitting and combining device are separated. In this case, the fixing member can be fixed or separated from the splitting and combining device in a more convenient way.

[0012] In addition, in the method disclosed herein, optionally, the fixing member can be embedded and connected to the splitting and combining device, and when the fixing member is embedded in the splitting and combining device, the fixing member and the splitting and combining device are fixed in the direction of the combination direction and the separation direction, and when the fixing member is removed from the splitting and combining device, the fixing member is separated from the splitting and combining device. In this case, the fixing member can be embedded in the splitting and combining device through a simple operation, so that the fixing member and the splitting and combining device can be fixed more conveniently.

[0013] In addition, in the method involved in the present disclosure, optionally, the separation and combination device includes a locking member and a first limit, the fixing member is sleeved on the locking member, the fixing member is movable on the separation and combination device in the combination direction or the separation direction, and the locking member is movable in the combination direction or the separation direction and is arranged on the separation and combination device, when the fixing member and the locking member are lower than the first limit, the fixing member and the separation and combination device are fixed in the direction of the separation direction, and when the fixing member and the locking member exceed the first limit, the fixing member and the separation and combination device are separated. In this case, by sleeve-mounting the fixing member on the locking member and making the fixing member and the locking member lower than or exceed the first limit, it is possible to easily fix or separate the fixing member from the separation and combination device.

[0014] In addition, in the method involved in the present disclosure, optionally, the separation and combination device further includes a second limit, the second limit is lower than the first limit in the separation direction, the second limit engages the locking member so that the fixing member and the locking member are lower than the first limit, and the second limit releases the locking member so that the fixing member and the locking member exceed the first limit. In this case, by making the locking member lower than or higher than the second limit, it is possible to facilitate making the fixing member and the locking member lower than or higher than the first limit.

[0015] In addition, in the method involved in the present disclosure, optionally, the splitting and combining device further includes a first elastic structure and a second elastic structure, the first elastic structure supports the locking member, the second elastic structure supports the second limit, and the first elastic structure and the second elastic structure store energy when the second limit engages the locking member; the first elastic structure and the second elastic structure release energy when the second limit releases the locking member. In this case, by making the first elastic structure and the second elastic structure store or release energy, it is possible to facilitate the splitting and combining device to be fixed or separated from the fixing member.

[0016] In addition, in the method disclosed herein, optionally, the separation and combination device includes a monitoring mechanism, a movable mechanism and a driving mechanism, and when the monitoring mechanism detects that the fixing member is placed in the separation and combination device, the driving mechanism drives the movable mechanism to clamp the fixing member so that the fixing member is fixed to the separation and combination device; after completing the replacement of the separation member, the driving mechanism drives the movable mechanism to release the fixing member so that the fixing member is separated from the separation and combination device. In this case, the accuracy of the timing of the separation and combination device triggering the movable mechanism can be improved through the monitoring mechanism; the movable mechanism can be made to clamp or release the fixing member through the driving mechanism; and the fixing member can be fixed or separated from the separation and combination device through the movable mechanism.

[0017] According to the present disclosure, a method for separating and combining medical equipment is provided, which can improve work efficiency and reduce hospital infection. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] Figure 1 is a schematic diagram showing a combination of a medical device 10 involved in the present disclosure; Figure 2 1 is a schematic diagram showing the separation of the medical device 10 involved in the present disclosure. Hereinafter, the direction in which the separator 110 is combined with the fixing member 120 is referred to as the combination direction D1; the direction in which the separator 110 is separated from the fixing member 120 is referred to as the separation direction D2. The combination direction D1 is opposite to the separation direction D2.

[0051] See also Figure 1 and Figure 2 In some examples, the medical device 10 may include a separator 110 and a fixing member 120. In some examples, the separator 110 and the fixing member 120 may be connected by a simple snap-fit, that is, the medical device 10 may be formed by combining the separator 110 and the fixing member 120 by a simple snap-fit.

[0052] Figure 3A 1 is a partial schematic diagram of a simple clamping connection between the separating member 110 and the fixing member 110 involved in the example of the present disclosure. In order to more clearly illustrate the structure of the simple clamping connection, Figure 3A The separation piece 110 is subjected to cross-section processing.

[0053] See also Figure 3A In some examples, simple snap-fitting may refer to a snap-fitting method in which the separating piece 110 and the fixing piece 120 can be combined when the separating piece 110 is pressed down to the fixing piece 120 in the combining direction D1, and the separating piece 110 and the fixing piece 120 can be separated when the separating piece 110 is taken out of the medical device 10 in the separating direction D2.

[0054] Figure 3B 1 is a partial schematic diagram of a threaded connection between the separating member 110 and the fixing member 110 involved in the example of the present disclosure. In order to more clearly illustrate the structure of the threaded connection, Figure 3B The separation piece 110 is subjected to cross-section processing.

[0055] See also Figure 3B In some examples, the connection between the separator 110 and the fixing member 120 can be a threaded connection, and the separator 110 can be combined with the fixing member 120 by screwing into the fixing member 120, or can be separated from the fixing member 120 by unscrewing the fixing member 120.

[0056] In some examples, the separation piece 110 may be a disposable medical device, such as a disposable dilator.

[0057] In other examples, the separate piece 110 may be a non-disposable medical device that needs to be replaced.

[0058] In some examples, the fixture 120 may be a non-disposable medical device. In some examples, the non-disposable medical device may also be referred to as a reusable medical device, that is, a reusable medical device, such as a reusable inspection mirror.

[0059] See also Figure 1 and Figure 2 In some examples, the separation and combination of the medical device 10 may refer to separating and replacing the separation component 110 from the medical device 10 through the separation and combination device 20, and then combining the replaced separation component 110 and the fixing component 120 to form an integrated unit for use.

[0060] Figure 4 is a flowchart showing a method of separating and combining the medical device 10 according to an example of the present disclosure.

[0061] In this embodiment, see Figure 4 The method for separating and combining the medical device 10 may include: fixing the fixing member 120 and the separating and combining device 20 (step S10); replacing the separating member 110 (step S20); and separating the fixing member 120 from the separating and combining device 20 (step S30).

[0062] In some examples, before step S10, the fixing member 120 may be aligned with the splitting and combining device 20. In this case, the fixing member 120 and the splitting and combining device 20 may be easily fixed.

[0063] In some examples, the split-and-combination device 20 may be configured to have magnetism when powered on and lose magnetism after power is turned off. In some examples, when the split-and-combination device 20 has magnetism, the magnetic attraction between the split-and-combination device 20 and the fixing member 120 may be greater than the force that separates the separation member 110 from the fixing member 120. In some examples, when the split-and-combination device 20 has magnetism, the fixing member 120 may be fixed to the split-and-combination device 20. In some examples, when the split-and-combination device 20 loses magnetism, the magnetic attraction between the split-and-combination device 20 and the fixing member 120 may be less than the force that separates the separation member 110 from the fixing member 120. In some examples, when the split-and-combination device 20 has magnetism, the fixing member 120 may be separated from the split-and-combination device 20. Specifically, the fixing member 120 may have a certain magnetism, or the fixing member 120 may be magnetized; before step S10, the split-and-combination device 20 may be powered on to have magnetism; after step S20 and before step S30, the split-and-combination device 20 may be powered off to lose magnetism. In this case, since the medical device 10 can be formed by a simple snap-fit ​​combination of a separator 110 and a fixing member 120, the separation and combination device 20 is magnetic after being powered on, and the fixing member 120 and the separation and combination device 20 can be fixed by magnetic attraction; when the separation member 110 needs to be replaced, the separation and combination device 20 can keep the fixing member 120 fixed on the separation and combination device 20 by a magnetic attraction force greater than the force that separates the separation member 110 from the fixing member 120; the separation and combination device 20 loses its magnetism after power is cut off, and at this time, the magnetic attraction force between the fixing member 120 and the separation and combination device 20 can be made smaller than the force that separates the separation member 110 from the fixing member 120, and when the fixing member 120 and the separation and combination device 20 are separated, the separation member 110 and the fixing member 120 can be kept in a combined state.

[0064] In some examples, the power-on and power-off states of the separation and combination device 20 can be switched regularly. For example, the switch is performed every 5 seconds. In this case, when the separation operation of the separation member 110 and the fixing member 120 needs to be performed on a large number of medical devices 10, the separation and combination device 20 can automatically switch between the power-on and power-off states, so that the separation and combination device 20 can automatically switch between the state of having magnetism or losing magnetism. At this time, medical staff can focus on separating and combining medical devices 10 without having to operate the separation and combination device 20 separately, thereby improving work efficiency.

[0065] In some examples, aligning the fixing member 120 with the split-and-joint device 20 may refer to aligning the fixing member 120 with a portion of the split-and-joint device 20 that is magnetically attracted.

[0066] Figure 5 1 is a partial schematic diagram showing the matching of the fixing member 120 and the separation and combination device 20 in a spiral manner according to the example of the present disclosure. In order to more clearly illustrate the matching method of the fixing member 120 and the separation and combination device 20, Figure 5 In the figure, the part where the splitting and combining device 20 and the fixing member 120 match is processed in section.

[0067] See also Figure 5 In some examples, the fixing member 120 and the splitting and combining device 20 can be matched in a spiral manner. In some examples, the fixing member 120 can be screwed into the splitting and combining device 20 so that the fixing member 120 and the splitting and combining device 20 are fixed in the direction of the combination direction D1 and the separation direction D2. In some examples, the fixing member 120 can be screwed out of the splitting and combining device 20 to separate the fixing member 120 from the splitting and combining device 20. In some examples, after the fixing member 120 is screwed into the splitting and combining device 20, the fixing member 120 and the splitting and combining device 20 can be fixed in the direction of the combination direction D1 and the separation direction D2. In other words, the fixing member 120 can be fixed to the splitting and combining device 20 in the direction of the combination direction D1 and the separation direction D2 through a spiral. In this case, since the fixing member 120 and the separation and combination device 20 are matched and fixed in a spiral manner, when the separation member 110 needs to be replaced in the combination direction D1 and the separation direction D2, the fixing member 120 can be fixed to the separation and combination device 20 more firmly, so that the fixing member 120 and the separation and combination device 20 can maintain a relatively stable state during the replacement of the separation member 110.

[0068] In some examples, the spiral manner may refer to a manner of screwing in or out in a threaded manner.

[0069] In some examples, the fixing member 120 can be rotatably movable on the separation device 20. In some examples, when the fixing member 120 rotates a first predetermined angle to the separation device, the fixing member 120 and the separation device 20 can be fixed in the direction of the combination direction D1 and the separation direction D2. In some examples, when the fixing member 120 rotates a second predetermined angle to the separation device 20, the fixing member 120 can be separated from the separation device 20. In this case, since the fixing member 120 and the separation device 20 are fixed or separated by rotating a predetermined angle, when the separation member 110 needs to be replaced in the combination direction D1 and the separation direction D2, the fixing member 120 can be fixed to the separation device 20 more firmly, so that the fixing member 120 and the separation device 20 can maintain a more stable state during the replacement of the separation member 110.

[0070] In some examples, the first predetermined angle may be greater than 0 degrees. In some examples, the first predetermined angle may be less than 180 degrees.

[0071] In some examples, the second predetermined angle may be greater than 0 degrees. In some examples, the second predetermined angle may be less than 180 degrees.

[0072] Fig. 6A2 is a partial schematic diagram showing that the splitting and combining device 20 involved in the example of the present disclosure includes a first matching portion 210 . Figure 6B 1 is a partial schematic diagram showing that the fixing member 120 involved in the example of the present disclosure includes a second matching portion 1210. In order to more clearly illustrate the matching method between the fixing member 120 and the separation and combination device 20, Fig. 6A The top view is used and only the partial structure of the splitting and combining device 20 and the fixing member 120 is shown. Figure 6B A front view is adopted and only the partial structure of the matching between the fixing member 120 and the separation and combination device 20 is shown.

[0073] See also Fig. 6A or Figure 6B In some examples, the splitting and combining device 20 may include a first matching portion 210. In some examples, the fixing member 120 may include a second matching portion 1210. In some examples, the first matching portion 210 may be a notch formed on the splitting and combining device 20. In some examples, the second matching portion 1210 may be a protrusion formed on the fixing member 120. In some examples, the protrusion on the fixing member 120 may pass through the notch on the splitting and combining device 20. In this case, the first matching portion 210 can be matched with the second matching portion 1210. When the second matching portion 1210 passes through the first matching portion 210, the fixing member 120 is rotated by a certain angle, so that the second matching portion 1210 and the first matching portion 210 are staggered, and the fixing member 120 and the splitting and combining device 20 can be fixed in the combination direction D1 and the separation direction D2.

[0074] In some examples, the first matching portion 210 may be a protrusion formed on the separation and combination device 20. In some examples, the second matching portion 1210 may be a notch formed on the fixing member 120. In some examples, the protrusion on the separation and combination device 20 may pass through the notch on the fixing member 120. In this case, the first matching portion 210 and the second matching portion 1210 can be matched, and when the second matching portion 1210 passes through the first matching portion 210, the fixing member 120 is rotated by a certain angle, so that the second matching portion 1210 and the first matching portion 210 can be staggered, and then the fixing member 120 and the separation and combination device 20 can be fixed in the combination direction D1 and the separation direction D2.

[0075] In some examples, the fixing member 120 can be slidably moved in the splitting and combining device 20. In some examples, when the fixing member 120 slides into the splitting and combining device 20, the fixing member 120 and the splitting and combining device 20 can be fixed in the combination direction D1 and the separation direction D2. In some examples, when the fixing member 120 slides out of the splitting and combining device 20, the fixing member 120 and the splitting and combining device 20 can be separated. In this case, the fixing member 120 can be fixed or separated from the splitting and combining device 20 in a more convenient way.

[0076] Figure 7 1 is a partial schematic diagram showing the matching of the fixing member 120 and the splitting and combining device 20 in a sliding manner according to the example of the present disclosure. In order to more clearly illustrate the matching method of the fixing member 120 and the splitting and combining device 20, Figure 7 The partial structure of the splitting and combining device 20 and the fixing member 120 matching each other is shown from a front view.

[0077] See also Figure 7 In some examples, the splitting and combining device 20 may include a first sliding portion 220. In some examples, the fixing member 120 may include a second sliding portion 1220. In some examples, the second sliding portion 1220 may slide into or out of the first sliding portion 220. In this case, the fixing member 120 may be fixed to or separated from the splitting and combining device 20 by the second sliding portion 1220 cooperating with the first sliding portion 220.

[0078] See also Figure 7 In some examples, the first sliding-in portion 220 may be a groove. In some examples, the groove may be formed on a plane of the splitting and combining device 20 perpendicular to the combination direction D1 and the separation direction D2. In some examples, the second sliding-in portion 1220 may be a convex strip. In some examples, the convex strip may be formed on a plane of the fixing member 120 perpendicular to the combination direction D1 and the separation direction D2. In this case, the groove and the convex strip can be made parallel, so that the second sliding-in portion 1220 can slide into the first sliding-in portion 220.

[0079] In some examples, the first slide-in portion 220 may be a convex strip. In some examples, the convex strip may be formed on a plane of the splitting and combining device 20 perpendicular to the combination direction D1 and the separation direction D2. In some examples, the second slide-in portion 1220 may be a groove. In some examples, the groove may be formed on a plane of the fixing member 120 perpendicular to the combination direction D1 and the separation direction D2. In this case, the groove can be made parallel to the convex strip, so that the first slide-in portion 220 can slide into the second slide-in portion 1220.

[0080] In some examples, the fixing member 120 can be embedded and snap-connected to the splitting and combining device 20. In some examples, when the fixing member 120 is embedded in the splitting and combining device 20, the fixing member 120 can be fixed to the splitting and combining device 20 in the direction of the combination direction D1 and the separation direction D2. In some examples, when the fixing member 120 is removed from the splitting and combining device 20, the fixing member 120 can be separated from the splitting and combining device 20. Specifically, when the connection mode between the separating member 110 and the fixing member 120 is a threaded connection, at this time, the combination direction D1 can be the direction in which the separating member 110 is screwed into the fixing member 120, and the separation direction D2 can be the direction in which the separating member 110 is screwed out of the fixing member 120, so that the direction in which the fixing member 120 is embedded in the splitting and combining device 20 can be approximately perpendicular to the combination direction D1 and the separation direction D2. In this case, the fixing member 120 can be embedded in the splitting and combining device 20 through simple operation, so that the fixing member 120 can be more convenient to fix to the splitting and combining device 20.

[0081] Fig. 8A It is a partial schematic diagram showing that the splitting and combining device 20 involved in the example of the present disclosure includes a first clamping position 230 . Figure 8B 1 is a partial schematic diagram showing that the fixing member 120 involved in the example of the present disclosure includes a second clamping position 1230. In order to more clearly illustrate the matching method between the fixing member 120 and the separation and combination device 20, Fig. 8A The top view is used and only the partial structure of the splitting and combining device 20 and the fixing member 120 is shown. Figure 8B A bottom-up perspective is adopted and only the partial structure of the matching between the fixing member 120 and the separation and combination device 20 is shown.

[0082] See also Fig. 8A or Figure 8B In some examples, the splitting and combining device 20 may include a first embedding position 230. In some examples, the fixing member 120 may include a second embedding position 1230. In some examples, the first embedding position 230 may be a protrusion formed on the splitting and combining device 20. In some examples, the second embedding position 1230 may be a non-circular groove formed on the fixing member 120. In some examples, the non-circular groove on the fixing member 120 may match the protrusion on the splitting and combining device 20. In this case, the first embedding position 230 can be matched with the second embedding position 1230. When the second embedding position 1230 is embedded with the first embedding position 230, when the separating member 110 is screwed into the fixing member 120 for assembly or the separating member 110 is screwed out of the fixing member 120 for separation, the fixing member 120 and the splitting and combining device 20 can be fixed in the assembly direction D1 and the separation direction D2.

[0083] In some examples, the first engaging position 230 may be a non-circular groove formed on the separation device 20. In some examples, the second engaging position 1230 may be a protrusion formed on the fixing member 120. In some examples, the protrusion on the fixing member 120 may match the non-circular groove on the separation device 20. In this case, the first engaging position 230 can be matched with the second engaging position 1230, and when the second engaging position 1230 is engaged with the first engaging position 230, when the separation member 110 is screwed into the fixing member 120 for assembly or the separation member 110 is screwed out of the fixing member 120 for separation, the fixing member 120 and the separation device 20 can be fixed in the assembly direction D1 and the separation direction D2.

Fig.9F 1 is an exploded view showing one embodiment of the splitter / joiner device 20 according to the example of the present disclosure.

[0085] It should be understood that in order to better illustrate the relationship between the locking member 240 and the first limit 250 and the second limit 260, 9A to 9E Only the half of the splitting and combining device 20 that is symmetrical about the fixing member 120 is shown, and some components that may cause obstruction or misunderstanding (such as the first elastic structure 2010 and the second elastic structure 2020) are ignored. Fig.9F A first elastic structure 2010 and a second elastic structure 2020 are shown.

[0086] See also 9A to 9EIn some examples, the splitting and combining device 20 may include a locking member 240. In some examples, the splitting and combining device 20 may also include a first limit 250. In some examples, the fixing member 120 may be sleeved on the locking member 240. In some examples, the fixing member 120 may be movable in the splitting and combining device 20 in the combination direction D1 or the separation direction D2. In some examples, the locking member 240 may be movably disposed in the splitting and combining device 20. In some examples, the locking member 240 may be movable in the combination direction D1 or the separation direction D2. See FIG. 9B to FIG. 9D In some examples, when the fixing member 120 and the locking member 240 are lower than the first limit position 250, the fixing member 120 and the separation and combination device 20 can be fixed in the separation direction D2. Fig.9E In some examples, when the fixing member 120 and the locking member 240 exceed the first limit position 250, the fixing member 120 can be separated from the separation device 20. In this case, by sleeve-arranging the fixing member 120 on the locking member 240 and making the fixing member 120 and the locking member 240 lower than or exceed the first limit position 250, the fixing member 120 can be easily fixed or separated from the separation device 20.

[0087] See also 9A to 9E In some examples, the locking member 240 may include a first locking portion 2410. Fig. 9B Zhihe Fig.9D In some examples, the locking member 240 being lower than the first limit position 250 may mean that the first locking portion 2410 is lower than the first limit position 250. 9A to 9E In some examples, the first locking portion 2410 may be located between the first limiter 250 and the fixing member 120. 9A to 9E In some examples, the first limiter 250 may be a slope-shaped structure formed on the inner side of the splitting and combining device 20 and gradually approaching the fixing member 120. In some examples, the first locking portion 2410 may move in a direction perpendicular to the combining direction D1 and the separating direction D2. Fig. 9B and Fig.9D In some examples, when the medical device 10 moves in the combination direction D1, the first locking portion 2410 can be lower than the first limit 250. In some examples, when the first locking portion 2410 is lower than the first limit 250, the first locking portion 2410 can move in a direction perpendicular to the combination direction D1 close to the first limit 250 until it abuts against the fixing member 120 in the medical device 10. In this case, when the first locking portion 2410 of the locking member 250 is lower than the first limit 250, the fixing member 120 and the separation device 20 can be fixed in the combination direction D1 and the separation direction D2.

[0088] See also 9A to 9EIn some examples, the separation and combination device 20 may further include a second limit position 260. In some examples, the second limit position 260 may be lower than the first limit position 250 in the separation direction D2. FIG. 9B to FIG. 9D In some examples, when the second limit position 260 is engaged with the locking member 240, the fixing member 120 and the locking member 240 can be lower than the first limit position 250. Fig.9A and Fig.9E In some examples, when the second limit 260 releases the locking member 240, the fixing member 120 and the locking member 240 can exceed the first limit 250. In this case, by making the locking member 240 lower than or higher than the second limit 260, it is easy to make the fixing member 120 and the locking member 240 lower than or higher than the first limit 250.

[0089] See also Fig.9A In some examples, the locking member 240 may further include a second locking portion 2420. In some examples, the second locking portion 2420 may move in the direction of the combination direction D1 and the separation direction D2 near the second limit position 260. In some examples, the second locking portion 2420 may act on the second limit position 260. FIG. 9B to FIG. 9D In some examples, the second locking portion 2420 can act on the second limit 260 so that the fixing member 120 and the locking member 240 can be lower than the first limit 250. In this case, through the cooperation between the second locking portion 2420 and the second limit 260, the fixing member 120 and the separation and combination device 20 can be fixed in the separation direction D2.

[0090] In some examples, the splitting and combining device 20 may further include a first elastic structure 2010 and a second elastic structure 2020. In some examples, the first elastic structure 2010 may support the locking member 240. In some examples, the second elastic structure 2020 may support the second limiter 260. In some examples, the first elastic structure 2010 and the second elastic structure 2020 may store energy when the second limiter 260 engages the locking member 240. In some examples, the first elastic structure 2010 and the second elastic structure 2020 may release energy when the second limiter 260 releases the locking member 240. In this case, by making the first elastic structure 2010 and the second elastic structure 2020 store or release energy, it is possible to facilitate the splitting and combining device 20 to be fixed or separated from the fixing member 120.

[0091] The following combination 9A to 9E , specifically describing the relationship between the locking member 240 and the first limiter 250 and the second limiter 260.

[0092] See also 9A to 9EIn some examples, the second locking portion 2420 may be a protruding structure formed in the middle portion of the locking member 240 in a direction close to the second limiter 260. In some examples, the second limiter 260 may be a block having a concave structure fixed to the splitting and combining device 20. In some examples, the protruding structure of the second locking portion 2420 may periodically engage with the concave structure of the second limiter 260. In this case, the second locking portion 2420 may be fixed to the second limiter 260.

[0093] See also 9A to 9E In some examples, the second position limiter 260 may include at least two groups of recessed structures. In some examples, the recessed structure of the second position limiter 260 may be formed by the abutment angle 2610 and the clamping angle 2620. In some examples, the protruding structure of the second locking portion 2420 may be formed by the horizontal side 2421 and the vertical side 2422. In some examples, when the abutment angle 2610 abuts the vertical side 2422 and the clamping angle 2620 abuts the horizontal side 2421, the protruding structure of the second locking portion 2420 may cooperate with the recessed structure of the second position limiter 260; when the clamping angle 2620 abuts the vertical side 2422 or the abutment angle 2610 abuts the horizontal side 2421, the protruding structure of the second locking portion 2420 may cancel the cooperation with the recessed structure of the second position limiter 260. In this case, by changing the abutting relationship between the clamping angle 2620 and the abutting angle 2610 and the horizontal side 2421 and the vertical side 2422 , the locking member 240 can be made to exceed the second limit position 260 or be lower than the second limit position 260 .

[0094] See also 9A to 9E In some examples, the horizontal side 2421 may be a side of the second locking portion 2420 that is perpendicular to the combination direction D1. In some examples, the vertical side 2422 may be a side of the second locking portion 2420 that is parallel to the combination direction D1.

[0095] See also Fig.9A , Fig. 9B and Fig.9F In some examples, the fixing member 120 can be moved in the combination direction D1 by pressing down. In some examples, during the movement of the fixing member 120 in the combination direction D1, the fixing member 120 can push the locking member 240 to move in the combination direction D1, and the first elastic structure 2010 can store energy. In some examples, during the movement of the locking member 240 in the combination direction D1, the second limiter 260 can have a tendency to rotate in the rotation direction D3. In some examples, after the locking member 240 moves in the combination direction D1 until the horizontal side 2421 is lower than the clamping angle 2620 of the first group of recessed structures, the clamping angle 2620 of the first group of recessed structures can be changed from abutting the vertical side 2422 to abutting the horizontal side 2421, and the second elastic structure 2020 can release part of the energy. In this way, the locking member 240 can be lower than the first limiter 250.

[0096] See also Fig. 9B and Fig. 9C In some examples, the first elastic structure 2010 can release part of the energy to the locking member 240 to make the locking member 240 move in the separation direction D2. In some examples, the second limiter 260 can rotate in the rotation direction D3 under the driving action of the locking member 240, the clamping angle 2620 of the first group of recessed structures can abut the horizontal side 2421, the abutting angle 2610 of the first group of recessed structures can abut the vertical side 2422, and the second elastic structure 2020 can store part of the energy. In this way, the locking member 240 can be kept below the first limiter 250.

[0097] See also Fig. 9C and Fig.9D , in some examples, pressing down again can make the fixing member 120 move in the combination direction D1. In some examples, during the movement of the fixing member 120 in the combination direction D1, the fixing member 120 can push the locking member 240 to move in the combination direction D1, and the first elastic structure 2010 can store energy again. In some examples, the locking member 240 can move in the combination direction D1 until the horizontal side 2421 is lower than the angle 2610 of the first group of recessed structures. In some examples, the second limiter 260 can rotate a certain angle in the rotation direction D3. In some examples, the angle 2610 of the first group of recessed structures can be changed from abutting the vertical side 2422 to abutting the horizontal side 2421, and the second elastic structure 2020 can release part of the energy. As a result, the second limiter 260 can be connected to the locking member 240 and transition to releasing the locking member 240.

[0098] See also Fig.9D and Fig.9E In some examples, the first elastic structure 2010 can release energy to the locking member 240 to make the locking member 240 move in the separation direction D2. In some examples, the abutment angle 2610 of the first group of recessed structures can abut the horizontal side 2421. In some examples, the second limiter 260 can rotate in the rotation direction D3 under the driving action of the locking member 240. In some examples, the second elastic structure 2020 can release part of the energy to the second limiter 260 so that the second limiter 260 can continue to rotate in the rotation direction D3 by a certain angle until the clamping angle 2620 of the second group of recessed structures abuts the vertical side 2422. In this way, the locking member 240 can exceed the first limiter 250.

Fig. 10B 2 is a schematic diagram showing a second state between the second locking portion 2420 and the second limiter 260 involved in the example of the present disclosure. Fig. 10C2 is a schematic diagram showing a third state between the second locking portion 2420 and the second limiter 260 involved in the example of the present disclosure. Fig. 10D 2 is a schematic diagram showing a fourth state between the second locking portion 2420 and the second limiter 260 involved in the example of the present disclosure. Fig.10E 2 is a schematic diagram showing that the second locking portion 2420 involved in the example of the present disclosure has a stepped structure 2427. In order to better illustrate the relationship between the second locking portion 2420 and the second limiter 260, FIG. 10A to FIG. 10D Some parts that may cause obstruction or misunderstanding are omitted, and repeated parts are not marked again.

[0100] The following combination FIG. 10A to FIG. 10E , specifically describing the relationship between the second locking portion 2420 and the second limiter 260.

[0101] It should be understood that in FIG. 10A to FIG. 10D The figure mainly shows the relationship between the second locking portion 2420 and the second limiter 260, wherein the first elastic structure 2010 and the first limiter 250 and other components not shown can be connected with Fig.9F The same as shown in FIG. 10A to FIG. 10D The second limit 260 may not be supported by the second elastic structure 2020.

[0102] See also FIG. 10A to FIG. 10E In some examples, the second locking portion 2420 may be a recessed area with multiple tracks formed in the middle portion of the locking member 240 in a direction close to the second limiter 260. In some examples, the second limiter 260 may be a rod-shaped object consisting of a fixed end 2630 fixedly disposed on the splitting and combining device 20 and a movable end 2640 movable on the second locking portion 2420. In some examples, the movable end 2640 may move along the multiple tracks of the recessed area in a predetermined order. In this case, the second limiter 260 can be movable on the second locking portion 2420.

[0103] See also FIG. 10A to FIG. 10E In some examples, the second locking portion 2420 may include a first track 2423, a second track 2424, a third track 2425, and a fourth track 2426. In some examples, the first track 2423, the second track 2424, the third track 2425, and the fourth track 2426 may be connected in sequence to form a complete loop.

[0104] See also Fig.10EIn some examples, the second locking part 2420 may have a step-like structure 2427 at the connection between at least one pair of adjacent tracks. Specifically, for example, the second track 2424 may be recessed to a certain depth toward the inside of the locking member 240 relative to the first track 2423, so as to form a step-like structure 2427 at the connection between the first track 2423 and the second track 2424. In some examples, the movable end 2640 may be closely attached to the multiple tracks of the second locking part 2420 in the inner direction of the locking member 240. In this case, after the movable end 2640 passes through the step-like structure 2427, it will not be able to reverse through the step-like structure 2427 and return to the previous track, that is, under the dual effects of the step-like structure 2427 and the movable end 2640 closely attached to the multiple tracks of the second locking part 2420 in the inner direction of the locking member 240, the movable end 2640 can move between the multiple tracks in sequence.

[0105] In some examples, the second locking portion 2420 has a step-like structure 2427 at the connection between adjacent tracks. In this case, after the splitting and combining device 20 performs multiple splitting and combining operations, the tendency of the movable end 2640 to move to a vertical position may weaken or even disappear. At this time, the movable end 2640 can move in the loop formed by the multiple tracks through the guidance of the step-like structure 2427 between each pair of adjacent tracks.

[0106] In some examples, a connection between the second rail 2424 and the third rail 2425 , a connection between the third rail 2425 and the fourth rail 2426 , and a connection between the fourth rail 2426 and the first rail 2423 may have a stepped structure 2427 .

[0107] In some examples, the track may include an inner side of the track and an outer side of the track. Specifically, for example, the inner side of the plurality of tracks may refer to a side within the range formed by the motion track of the active end 2640, and the outer side of the plurality of tracks may refer to a side outside the range formed by the motion track of the active end 2640.

[0108] See also FIG. 10A to FIG. 10E In some examples, the third track 2425 may have a first fixed position 2425a. In some examples, the first fixed position 2425a may be formed by bending the inner side of the third track 2425 in the combination direction D1. In some examples, the movable end 2640 may be stably stationary at the first fixed position 2425a. In this case, when the movable end 2640 moves to the first fixed position 2425a in the plurality of tracks, it can be stably stationary at the first fixed position 2425a, thereby enabling the locking member 240 to be lower than the first limit position 250.

[0109] See also FIG. 10A to FIG. 10EIn some examples, the first track 2423 may have a second fixed position 2423a. In some examples, the second fixed position 2423a may be formed by bending the outer side of the first track 2423 toward the combination direction D1. In some examples, the movable end 2640 may be stably stationary at the second fixed position 2423a. In this case, when the movable end 2640 moves to the second fixed position 2423a in the plurality of tracks, it can be stably stationary at the second fixed position 2423a, thereby enabling the locking member 240 to exceed the first limit position 250.

[0110] Combination Fig. 10A , Fig. 10B and Fig.10E In some examples, the fixing member 120 can be moved in the combination direction D1 by pressing down. In some examples, during the movement of the fixing member 120 in the combination direction D1, the fixing member 120 can push the locking member 240 to move in the combination direction D1. In some examples, the movable end 2640 stationary at the second fixed position 2423a can move along the first track 2423 under the action of the stepped structure 2427 at the connection between the fourth track 2426 and the first track 2423. In some examples, the movable end 2640 can deviate from the original vertical position under the action of the first track 2423, and can have a tendency to move to the vertical position. In some examples, after the movable end 2640 passes through the connection between the first track 2423 and the second track 2424, it can quickly move to the vertical position to abut the outer side of the second track 2424. In this case, the movable end 2640 can move from the first track 2423 to the second track 2424.

[0111] In some examples, the connection point between the fourth track 2426 and the inner side of the first track 2423 may deviate from the fixed end 2630 in the direction of the fourth track 2426. In some examples, when the locking member 240 moves in the combination direction D1, the movable end 2640 may abut against the inner side of the first track 2423, but may not abut against the inner side of the fourth track 2426. In some examples, the second locking portion 2420 may not have a stepped structure 2427 at the connection between the fourth track 2426 and the first track 2423. In this case, when the locking member 240 moves in the combination direction D1, the movable end 2640 can move along the first track 2423 toward the second track 2424 without entering the fourth track 2426 from the first track 2423. At the same time, since the second locking portion 2420 does not have a stepped structure 2427 at the connection between the fourth track 2426 and the first track 2423, the structure of the second locking portion 2420 can be simplified.

[0112] Combination Fig. 10B and Fig. 10CIn some examples, the first elastic structure 2010 can store energy when the locking member 240 and the fixing member 120 move in the combination direction D1. In some examples, the first elastic structure 2010 can release energy to the locking member 240 to make the locking member 240 move in the separation direction D2. In some examples, during the movement of the locking member 240 in the separation direction D2, the movable end 2640 can move from the second track 2424 to the third track 2425, and can be stationary at the first fixed position 2425a of the third track 2425. In this way, the locking member 240 can be lower than the first limit position 250, so that the fixing member 120 can be fixed to the separation device 20.

[0113] Combination Fig. 10C , Fig. 10D and Fig.10E , in some examples, pressing down again can make the fixing member 120 move in the combination direction D1. In some examples, during the movement of the fixing member 120 in the combination direction D1, the fixing member 120 can push the locking member 240 to move in the combination direction D1, the first elastic structure 2010 can store energy, and the movable end 2640 stationary at the first fixed position 2425a can move along the third track 2425 under the action of the stepped structure 2427 at the connection between the second track 2424 and the third track 2425. In some examples, the movable end 2640 can deviate from the original vertical position along the third track 2425 and can have a tendency to move to the vertical position. In some examples, after the movable end 2640 passes through the stepped structure 2427 at the connection between the third track 2425 and the fourth track 2426, the movable end 2640 can move from the third track 2425 to the fourth track 2426.

[0114] In some examples, the connection point between the second track 2424 and the outer side of the third track 2425 may deviate from the fixed end 2630 in the direction of the second track 2424. In some examples, when the locking member 240 and the fixing member 120 are moved in the combination direction D1 again, the locking member 240 may move in the combination direction D1. In some examples, during the movement of the locking member 240 in the combination direction D1, the movable end 2640 may abut against the outer side of the third track 2425, but may not abut against the outer side of the second track 2424. In some examples, the second locking portion 2420 may not have a stepped structure 2427 at the connection between the second track 2424 and the third track 2425. In this case, when the locking member 240 and the fixing member 120 are moved in the combination direction D1 again, the movable end 2640 can be moved along the third track 2425 in the direction of the fourth track 2426 without entering the second track 2424 from the third track 2425. At the same time, since the connection between the second track 2424 and the third track 2425 does not have a stepped structure 2427, the structure of the second locking portion 2420 can be simplified.

[0115] In some examples, the connection between the third track 2425 and the fourth track 2426 may have a stepped structure 2427. In some examples, the movable end 2640 may have a tendency to move toward a vertical position. In some examples, after the movable end 2640 passes through the connection between the third track 2425 and the fourth track 2426, the movable end 2640 may abut against the stepped structure 2427 at the connection between the third track 2425 and the fourth track 2426, and may not be able to return directly from the fourth track 2426 to the third track 2425. In this case, the movable end 2640 can be moved from the third track 2425 to the fourth track 2426.

[0116] Combination Fig. 10A , Fig. 10D and Fig.10E In some examples, the first elastic structure 2010 can store energy when the locking member 240 and the fixing member 120 are moved in the combination direction D1 again. In some examples, the first elastic structure 2010 can release energy to the locking member 240 to make the locking member 240 move in the separation direction D2. In some examples, during the movement of the locking member 240 in the separation direction D2, the movable end 2640 can move from the fourth track 2426 to the first track 2423 under the guidance of the stepped structure 2427 at the connection between the third track 2425 and the fourth track 2426 and the fourth track 2426. In some examples, the movable end 2640 can be stationary at the second fixed position 2423a of the first track 2423. As a result, the locking member 240 can exceed the first limit position 250, so that the fixing member 120 can be separated from the separation device 20.

[0117] Fig.11 2 is a schematic diagram showing the structure of the separation and combination device 20 involved in the example of the present disclosure, including a monitoring mechanism 270, a movable mechanism 280 and a driving mechanism 290. It is not difficult to understand that, under the premise of realizing the functions of each mechanism, the position and state of the monitoring mechanism 270, the movable mechanism 280 and the driving mechanism 290 should not be affected. Fig.11 Limitations of Content Displayed.

[0118] In some examples, the splitting and combining device 20 may include a monitoring mechanism 270, a movable mechanism 280, and a driving mechanism 290. In some examples, when the monitoring mechanism 270 detects that the fixing member 120 is placed in the splitting and combining device 20, the driving mechanism 290 may drive the movable mechanism 280 to clamp the fixing member 120. In some examples, the movable mechanism 280 clamps the fixing member 120 so that the fixing member 120 can be fixed to the splitting and combining device 20. In some examples, after the separation member 110 is replaced, the driving mechanism 290 may drive the movable mechanism 280 to release the fixing member 120. In some examples, the movable mechanism 280 releases the fixing member 120 so that the fixing member 120 can be separated from the splitting and combining device 20. In this case, the accuracy of the timing of the splitting and combining device 20 triggering the movable mechanism 280 can be improved through the monitoring mechanism 270; the movable mechanism 280 can clamp or release the fixing member 120 through the driving mechanism 290; and the fixing member 120 can be fixed or separated from the splitting and combining device 20 through the movable mechanism 280.

[0119] In some examples, the monitoring mechanism 270 can determine whether the fixing member 120 is placed in the separation and combination device 20 by monitoring whether the signal transmission is interrupted. In some examples, the monitoring mechanism 270 may include a transmitting end and a receiving end. In some examples, a space for the fixing member 120 to be placed can be reserved between the transmitting end and the receiving end. In some examples, the transmitting end can transmit a signal to the receiving end. In some examples, when the fixing member 120 is placed in the space reserved between the transmitting end and the receiving end, the signal transmission between the transmitting end and the receiving end can be interrupted by the fixing member 120, and the monitoring mechanism 270 can determine that the fixing member 120 has been placed in the separation and combination device 20.

[0120] In some examples, the movable mechanism 280 may include a push rod 2810, a swing rod 2820, and a support rod 2830. In some examples, the push rod 2810 may be extended and retracted. In some examples, the extension and retraction of the push rod 2810 may drive the swing rod 2820 to swing with the support rod 2830 as a fulcrum. In some examples, when the monitoring mechanism 270 determines that the fixing member 120 has been placed in the separation and combination device 20, the push rod 2810 may be extended to swing the swing rod 2820 in a direction close to the fixing member 120. In some examples, the swing rod 2820 swinging in a direction close to the fixing member 120 may clamp the fixing member 120. In some examples, the push rod 2810 may be retracted to swing the swing rod 2820 in a direction away from the fixing member 120. In some examples, the swing rod 2820 swinging in a direction close to the fixing member 120 may release the fixing member 120. In this case, the movable mechanism 280 can clamp or release the fixing member 120 through the cooperation of the push rod 2810 , the rocker rod 2820 and the support rod 2830 .

[0121] In some examples, the drive mechanism 290 may be an electric drive mechanism. In some examples, the electric drive mechanism may extend or retract the push rod 2810 by mechanically driving the push rod 2810 .

[0122] In some examples, the driving mechanism 290 may be a gas driving mechanism. In some examples, the gas driving mechanism may drive the push rod 2810 to extend or retract by gas expansion or contraction.

[0123] In some examples, the drive mechanism 290 may be a liquid drive mechanism. In some examples, the liquid drive mechanism may drive the push rod 2810 to extend or retract by liquid flow.

[0124] In some examples, after the replacement of the separation member 110 is completed, the push rod 2810 can be retracted by means of pressure sensing, optical sensing, or a manually controlled button.

[0125] In some examples, after the push rod 2810 is extended, the push rod 2810 can be automatically retracted after a certain period of time. For example, the push rod 2810 is automatically retracted after 5 seconds. In this case, when it is necessary to perform a large-scale separation operation of the separation member 110 and the fixing member 120 on the medical equipment 10, the medical staff can focus on separating and combining the medical equipment 10 without operating the separation and combination device 20, thereby improving work efficiency.

[0126] Fig.12 is a flowchart showing a method of replacing the separator 110 according to an example of the present disclosure.

[0127] In this embodiment, see Fig.12The method for replacing the separation piece 110 may include: separating the separation piece 110 from the medical device 10 (step S210); taking out a prepared new separation piece 110 (step S220); and combining the new separation piece 110 with the fixing piece 120 (step S230).

[0128] In some examples, in step S210 , separating the separation piece 110 from the medical device 10 may refer to separating the separation piece 110 from the fixing piece 120 along the separation direction D2 .

[0129] In some examples, in step S230 , combining the new separation component 110 with the fixing component 120 may refer to recombining the new separation component 110 with the fixing component 120 along the combination direction D1 into a new medical device 10 .

[0130] In this embodiment, the medical staff can operate the separator 110 to fix or separate the fixing member 120 in the medical device 10 and the separation device 20. After the fixing member 120 and the separation device 20 are fixed, the separator 110 can be replaced. When replacing the separator 110, only the separator 110 can be touched without touching the fixing member 120. In this way, the work efficiency can be improved and the hospital infection can be reduced.

Those skilled in the art may modify and change the present disclosure as needed without departing from the essential spirit and scope of the present disclosure, and these modifications and changes all fall within the scope of the present disclosure.
