Description

Technical Field

[0001] The present disclosure relates to the field of medical devices, and in particular to a device and method for separating and combining medical assemblies. Background Art

[0002] In the daily work process of the hospital, it is often necessary to combine disposable medical devices and reusable medical devices into medical assemblies for use, and after use, the disposable medical devices need to be separated from the medical assemblies and discarded, and then new disposable medical devices need to be recombined with the reusable medical devices for use, so the operations of separating and combining medical devices need to be performed frequently.

[0003] Currently, medical personnel mainly separate and combine medical components by using their hands to directly contact reusable medical devices and to contact 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; it is easy to cause infection among medical staff or between patients, and contamination of reusable medical devices by disposable medical devices, and has high requirements for subsequent disinfection operations, which increases the frequency of disinfection of reusable medical devices and reduces the efficiency of use, thereby increasing the maintenance cost of reusable medical devices.

[0005] In summary, there is a need for a replacement device that can improve work efficiency, be easy to use, and reduce hospital infection to separate and combine medical components. Summary of the invention

[0057] The device for separating and combining medical assemblies involved in the present disclosure may also be referred to as a separation and combination device, or may be simply referred to as a device. The medical assembly involved in the present disclosure may also be simply referred to as an assembly. The method for separating and combining medical assemblies involved in the present disclosure may also be simply referred to as a separation and combination method.

[0058] In some examples, the separation and combination device can also be used to separate and combine non-medical components, preferably to separate and combine medical components. Therefore, the following content is mainly described around the separation and combination of medical components.

[0059] The following describes in detail the device and method for separating and combining medical assemblies according to the present disclosure in conjunction with the accompanying drawings and a number of specific embodiments.

[0060] Figure 1is a schematic diagram showing the assembly 2 involved in the present disclosure about to be inserted into the separation and combination device 1, see Figure 1 , hereinafter, the direction of inserting the assembly 2 (i.e., the inserting direction or the pressing direction) is referred to as the inserting direction D1; Figure 2 2 is a schematic diagram showing the separation member 20 involved in the present disclosure being extracted from the assembly 2, see Figure 2 , the direction of pulling out the separation member 20 (ie, the pulling-out direction or the rebound direction) is referred to as the pulling-out direction D2 hereinafter, wherein the insertion direction D1 is opposite to the pulling-out direction D2 .

[0061] See also Figure 1 and Figure 2 In some examples, the assembly 2 can be formed by combining the separation member 20 and the fixing member 21. In some examples, the connection method of the separation member 20 and the fixing member 21 can be a simple snap connection, that is, the assembly 2 can be formed by combining the separation member 20 and the fixing member 21 by a simple snap connection.

[0062] In some examples, simple snap-fitting may mean that when the separator 20 is pressed down to the fixing member 21 in the insertion direction D1, the separator 20 and the fixing member 21 can be combined to form the assembly 2, and when the separator 20 is pulled out from the assembly 2 in the withdrawal direction D2, the separator 20 and the fixing member 21 can be separated.

[0063] In some examples, the separation member 20 and the fixing member 21 may be connected in a threaded manner, and the separation member 20 may be screwed into the fixing member 21 to be combined with the fixing member 21 , or may be screwed out of the fixing member 21 to be separated from the fixing member 21 .

[0064] In some examples, the separation piece 20 may be a disposable medical device, such as a disposable dilator, etc. In other examples, the separation piece 20 may be a non-disposable medical device that needs to be replaced.

[0065] In some examples, the fixing member 21 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.

[0066] See also Figure 1 and Figure 2 In some examples, the separation and combination assembly 2 may refer to separating and replacing the separation component 20 from the assembly 2 through the separation and combination device 1, and then combining the replaced separation component 20 and the fixing component 21 to form the assembly 2 for the next use.

[0067] Figure 3 This is a diagram showing the Figure 1 Magnified view of area a in FIG.

[0068] See also Figure 3 In some examples, the fixture 21 may include a connection line 210 , and the connection line 210 may be a line connecting the fixture 21 to other devices, such as a power line, a signal transmission line, etc.

[0069] Figure 4 1 is an exploded view showing the splitting and combining device 1 according to the present disclosure.

[0070] See also Figure 4 In some examples, the splitting and combining device 1 may include a supporting structure 10, a locking structure 11 and an elastic structure 12. The supporting structure 10 may be used to set the locking structure 11 and the elastic structure 12.

[0071] In some examples, a locking structure 11 and an elastic structure 12 may be disposed inside the supporting structure 10 .

[0072] In some examples, the elastic structure 12 can be configured to act on the locking structure 11 so that the locking structure 11 locks and / or unlocks the fixing member 21 , that is, the locking structure 11 and the elastic structure 12 can cooperate to lock and / or unlock the fixing member 21 .

[0073] See also Figure 4 In some examples, the locking structure 11 may include a center piece 15 , a first locking portion 16 , and a second locking portion 17 .

[0074] In some examples, the locking structure 11 locking and / or unlocking the fixing member 21 may mean that the first locking portion 16 locks and / or unlocks the fixing member 21, and the second locking portion 17 locks and / or unlocks the central member 15. In this case, the assembly 2 can be separated and assembled.

[0075] In some examples, the process of using the separation and combination device 1 to separate and combine the assembly 2 may refer to the first pressing of the assembly 2 on the center piece 15, and the fixing piece 21 pushing the center piece 15 so that the first locking portion 16 locks the fixing piece 2 (hereinafter, the state in which the first locking portion 16 locks the fixing piece 21 may also be referred to as the preliminary locking state), and the second locking portion 17 locks the center piece 15 (hereinafter, the state in which the second locking portion 17 locks the center piece 15 may also be referred to as the fully locked state) to replace the separator 20 in the assembly 2. In some examples, the fully locked state may refer to a firm connection relationship formed between the fixing piece 21 and the separation and combination device 1, at which time the separator 20 may be manually separated from the fixing piece 21 so as to replace the separator 20.

[0076] In addition, the assembly 2 is pressed down on the center piece 15 for a second time, so that the second locking portion 17 unlocks the center piece 15 (hereinafter, the state in which the second locking portion 17 unlocks the center piece 15 may also be referred to as the initial unlocking state), and the first locking portion 16 unlocks the fixing piece 21 (hereinafter, the state in which the first locking portion 16 unlocks the fixing piece 21 may also be referred to as the complete unlocking state), so as to pull out the assembly 2. In this case, during the process of replacing the separator 20, the user only needs to contact (for example, hold) the separator 20, put the separator 20 on the fixing piece 21 to form the assembly 2, and then press the assembly 2 down on the center piece 15 to separate the assembly 2 from the separation and combination device 1 to pull out the assembly 2. In this way, the work efficiency and the convenience of use can be improved, and the possibility of hospital infection can be reduced.

[0077] In some examples, before the assembly 2 is pressed down on the central piece 15 for the first time (ie, before the splitting and combining device 1 is used to split and combine the assembly 2 ), the splitting and combining device 1 may be in an initial state.

[0078] In some examples, after the first locking portion 16 locks the fixing member 21 and before the second locking portion 17 locks the central member 15, the assembly 2 and the central member 15 may rebound under the action of the elastic structure 12. In this case, the second locking portion 17 can lock the central member 15 through the rebound action of the elastic structure 12.

[0079] In addition, after the second locking portion 17 unlocks the center piece 15, before the first locking portion 16 unlocks the fixing member 21, the assembly 2 and the center piece 15 can rebound under the action of the elastic structure 12. In this case, the second locking portion 17 can unlock the center piece 15 through the rebound effect of the elastic structure 12.

[0080] See also Figure 4 In some examples, the support structure 10 may be split. In some examples, when the support structure 10 is split, the support structure 10 may include a first support member 13 and a second support member 14 , and the first support member 13 and the second support member 14 may be combined to form the support structure 10 .

[0081] In some examples, the support structure 10 may be integrated, and a locking structure 11 and an elastic structure 12 may be disposed inside the support structure 10 .

[0082] In some examples, the first support member 13 can be used to provide a setting space for the locking structure 11 and the elastic structure 12. In this case, a force support point can be provided for the elastic structure 12.

[0083] In some examples, the center piece 15 can be used to insert the assembly 2. Specifically, the center piece 15 can have a hollow channel. In this case, the assembly 2 can be inserted into the separation device 1.

[0084] In some examples, the insertion of the assembly 2 into the central piece 15 may refer to the fixing piece 21 in the assembly 2 being partially inserted into the central piece 15 .

[0085] See also Figure 3 In some examples, the fixing member 21 pushing the center piece 15 may mean that the fixing member 21 may have an expansion portion 212 that abuts against the center piece 15. In this case, the fixing member 21 can push the center piece 15 during the process of pressing the assembly 2 on the center piece 15 so that the assembly 2 and the center piece 15 move together.

[0086] In some examples, the fixing member 21 pushing the central member 15 may mean that the fixing member 21 does not have the expansion portion 212, but the central member 15 has a protruding portion inside, and the portion of the fixing member 21 inserted into the central member 15 can abut against the protruding portion. In this case, the fixing member 21 can also push the central member 15 during the process of pressing the assembly 2 down on the central member 15 so that the assembly 2 and the central member 15 move together.

[0087] In some examples, the center piece 15 is movably disposed in the support structure 10. In some examples, the center piece 15 is movably disposed in the support structure 10 may refer to the center piece 15 being movably disposed in the first support piece 13. Specifically, the center piece 15 is movable in the first support piece 13 in the insertion direction D1 and the extraction direction D2.

[0088] See also Figure 2 In some examples, the support structure 10 may include a first opening 100 for passing the connection line 210. In other words, the first opening 100 may pass the connection line 210.

[0089] Figure 5 1 is a schematic diagram showing the structure of the first support member 13 involved in the present disclosure, wherein, in order to better display the internal structure of the first support member 13, some components and lines that may cause obstruction or misunderstanding are omitted. Figure 6 Schematic diagram showing the structure of the second support member 14 involved in the present disclosure.

[0090] See also Figure 5 and Figure 6 In some examples, the support structure 10 may include the first opening 100, which may mean that the first support member 13 may include the first opening 100 and the second support member 14 may include the first opening 100. That is, the first opening 100 may be formed on the same side of the first support member 13 and the second support member 14.

[0091] In some examples, the second support member 14 may be fixed to the first support member 13. In this case, a force support point can be provided for the elastic structure 12.

[0092] See also Figure 6 In some examples, the second support member 14 may include a first groove 140. In some examples, the first groove 140 may match the elastic structure 12 to limit the position of the elastic structure 12 in the second support member 14 and may be used to position the elastic structure 12. In this case, a force support point can be provided for the elastic structure 12.

[0093] See also Figure 6 In some examples, the second support member 14 may further include a connection handle 141, which may be connected to the external bracket to form a fixed connection between the separation device 1 and the external bracket. In this case, when inserting the assembly 2 or extracting the assembly 2 or extracting the separation member 20, the external bracket can provide a reaction force for the separation device 1. Thus, the convenience of manually separating the fixing member 21 and the separation member 20 can be improved.

[0094] Figure 7 Schematic diagram showing the structure of the center piece 15 involved in the present disclosure.

[0095] See also Figure 7 In some examples, the center piece 15 may include a second opening 150 for passing the connection line 210. In this case, when the fixing piece 21 includes the connection line 210, the first opening 100 and the second opening 150 can facilitate the assembly 2 to be separated and combined by the separation and combination device 1.

[0096] In some examples, the fixing member 21 may not include the connection line 210. In this case, the supporting structure 10 may not include the first opening 100, and the center member 15 may not include the second opening 150. In this case, the processing steps of the supporting structure 10 and the center member 15 can be simplified.

[0097] See also Figure 7 In some examples, the center piece 15 may further include a second groove 151 for positioning the elastic structure 12. In some examples, the center piece 15 may be sleeved on the elastic structure 12 through the second groove 151.

[0098] In some examples, the elastic structure 12 can act on the center piece 15. In this case, when the assembly 2 is pressed down to move in the insertion direction D1, the elastic structure 12 is compressed, so that the elastic structure 12 can rebound in the extraction direction D2, and then can act on the center piece 15 to move the center piece 15 in the extraction direction D2.

[0099] See also Figure 4In some examples, preferably, the number of the elastic structures 12 may be two.

[0100] In some examples, the number of the elastic structures 12 may be plural. In some examples, the number of the second grooves 151 may be equal to the number of the elastic structures 12. In some examples, the number of the first grooves 140 may be equal to the number of the elastic structures 12.

[0101] In some examples, the plurality of elastic structures 12 may be symmetrically arranged, so that the center piece 15 can be subjected to a relatively balanced force when it moves in the first support piece 13 .

[0102] In some examples, the elastic structure 12 may be a spring, etc. In other examples, the elastic structure 12 may be an elastic component. In this case, the elastic structure 12 may have a rebound effect.

[0103] In some examples, the first locking portion 16 may be used to lock and / or unlock the fixing member 21 .

[0104] See also Figure 7 In some examples, the center piece 15 may further include a first limiting portion 152 for setting the first locking portion 16 .

[0105] In some examples, the first locking portion 16 is movably disposed on the center piece 15. In some examples, the first locking portion 16 being movably disposed on the center piece 15 may mean that the first locking portion 16 is movably disposed on the first limiting portion 152. Specifically, the first locking portion 16 is movable in the first limiting portion 152. In this case, when the first locking portion 16 is movable in the first limiting portion 152, the first locking portion 16 can lock and / or unlock the fixing member 21.

[0106] In some examples, the first position-limiting portion 152 may be a through hole with different apertures at both ends. In some examples, the first locking portion 16 may be, for example, a sphere. In some examples, the diameter of the first locking portion 16 may be larger than the aperture of the end of the first position-limiting portion 152 close to the fixing member 21. In some examples, the diameter of the first locking portion 16 may be smaller than the aperture of the end of the first position-limiting portion 152 away from the fixing member 21. In this case, the first locking portion 16 can be prevented from disengaging from the first position-limiting portion 152 when it moves in the first position-limiting portion 152 toward the end close to the fixing member 21.

[0107] In some examples, the support structure 10 may be configured to block the first locking portion 16 so that the first locking portion 16 is retained in the first limiting portion 152. In this case, the splitting and combining device 1 can be used for a long time.

[0108] In some examples, the support structure 10 may have a protrusion 101 on one side close to the center piece 15 that acts on the first locking portion 16 to allow the first locking portion 16 to lock the fixing piece 21 .

[0109] See also Figure 5 In some examples, the support structure 10 may have a protrusion 101, which may mean that the first support member 13 of the support structure 10 may have a protrusion 101 on one side close to the center member 15. In this case, the protrusion 101 enables the first locking portion 16 to move in the first limiting portion 152 toward the end close to the fixing member 21, thereby enabling the first locking portion 16 to lock the fixing member 21.

[0110] In some examples, the protrusion 101 may be formed by a portion of the support structure 10 protruding toward the center piece 15 from a side close to the center piece 15 .

[0111] In some examples, the support structure 10 can be configured to block the first locking portion 16, which means that when the splitting and combining device 1 is in a working state or a non-working state, the support structure 10 can block the first locking portion 16 from being separated from the end of the first limiting portion 152 away from the fixing member 21 when the splitting and combining device 1 is shaken, tilted, or inverted. Specifically, for example, when the first locking portion 16 is a ball, the maximum vertical distance from the support structure 10 to the center piece 15 can be less than the radius of the first locking portion 16; the support structure 10 can exceed at least half of the first locking portion 16 in the withdrawal direction D2.

[0112] In some examples, the first locking portion 16 may be at least partially exposed outside the first limiting portion 152. Specifically, for example, when the first limiting portion 152 is a through hole and the first locking portion 16 is a ball, the diameter of the first locking portion 16 is greater than the hole depth of the first limiting portion 152. In this case, when the center piece 15 moves in the insertion direction D1 or in the withdrawal direction D2, the first locking portion 16 can abut against the support structure 10 and the fixing member 21, and then the center piece 15 and the assembly 2 can move together during the pressing or rebounding process of the center piece 15, thereby enabling the first locking portion 16 to lock and / or unlock the fixing member 21.

[0113] In some examples, when one end of the first locking portion 16 close to the fixing member 21 is exposed outside the first limiting portion 152, the first locking portion 16 can engage the fixing member 21. In this case, the first locking portion 16 can lock the fixing member 21 during the pressing process of the assembly 2.

[0114] See also Figure 3In some examples, the fixing member 21 may further include a third groove 211 for matching with the first locking portion 16. In some examples, the first locking portion 16 clamping the fixing member 21 may refer to the first locking portion 16 clamping the third groove 211 of the fixing member 21.

[0115] See also Figure 7 In some examples, the center piece 15 may further include a second limiting portion 153, and the support structure 10 may abut against the second limiting portion 153 to limit the movement of the center piece 15 in the support structure 10. In this case, the second limiting portion 153 can keep the center piece 15 in a relatively stable state in the support structure 10.

[0116] See also Figure 7 In some examples, the second limiting portion 153 may be formed by extending from a side of the center piece 15 close to the second groove 151 toward the second groove 151 and connecting with the second groove 151 .

[0117] In some examples, the central piece 15 can maintain a relatively stable state in the support structure 10 when the separation and combination device 1 is used to separate and combine the assembly 2. During the pressing process, the central piece 15 moves in the insertion direction D1 under the push of the fixing member 21; during the rebound process of the central piece 15, the central piece 15 moves in the withdrawal direction D2 under the action of the elastic structure 12. In this case, the second limiting portion 153 can keep the central piece 15 moving in the support structure 10.

[0118] In some examples, the second locking portion 17 can lock the center piece 15. In some examples, the second locking portion 17 can unlock the center piece 15.

[0119] In some examples, the second locking portion 17 is movably disposed in the supporting structure 10 .

[0120] Fig. 8A Schematic diagram showing the structure of the second locking portion 17 involved in the present disclosure. Figure 8B It is a schematic structural diagram showing that the second locking portion 17 involved in the present disclosure provides a force through the driving portion 172 . Fig. 9 1 is a schematic structural diagram showing a modified example of the second locking portion 17 according to the present disclosure.

[0121] See also Fig. 8A and Fig. 9In some examples, the second locking portion 17 may include a fixed portion 170 fixed to the support structure 10 and a movable portion 171 movable on the support structure 10. In some examples, the movable portion 171 may be combined with the fixed portion 170 and the movable portion 171 may have a tendency to move around the fixed portion 170. In some examples, the movable portion 171 may lock and / or unlock the center piece 15. In this case, since the movable portion 171 has a tendency to move around the fixed portion 170, when the movable portion 171 moves around the fixed portion 170, the movable portion 171 can lock and / or unlock the center piece 15.

[0122] In some examples, the tendency of the movable portion 171 to move may mean that the movable portion 171 has a tendency to rotate around the fixed portion 170. In some examples, the rotation direction of the movable portion 171 around the fixed portion 170 may be referred to as the rotation direction D3. In this case, the movable portion 171 can be moved on the support structure 10.

[0123] In some examples, the fixed portion 170 may not provide a force to the movable portion 171 to make the movable portion 171 have a tendency to move, but may provide a force to the movable portion 171 through another component.

[0124] Fig.10 It is a schematic diagram showing a modified example of the second locking part 17 involved in the present disclosure, in which a force is provided by the driving part 172. In order to mainly highlight the positional relationship between the driving part 172, the movable part 171 and the center piece 15, some parts and lines that may cause obstruction or misunderstanding are omitted.

[0125] See also Figure 8B and Fig.10 In some examples, the second locking portion 17 may further include a driving portion 172. In some examples, the driving portion 172 may abut against the movable portion 171 and provide a force to the movable portion 171. In some examples, the direction of the force may deviate from the fixed portion 170 toward the center piece 15.

[0126] In some examples, the movable portion 171 may have a tendency to move around the fixed portion 170 under the action of the driving portion 172. Figure 8B The driving part 172 can be disposed between the fixed part 170 and the movable part 171. When the movable part 171 moves around the fixed part 170, since the fixed part 170 is fixed to the supporting structure 10, the driving part 172 can be deformed to generate elastic force acting on the movable part 171. Thus, the movable part 171 can have a tendency to move.

[0127] In addition, combined Figure 4 and Fig.10, the driving part 172 may be disposed on the supporting structure 10, and the driving part 172 may be configured to deviate from the fixed part 170 and abut the movable part 171 in a direction close to the center piece 15. In this case, by the driving part 172 acting on the movable part 171 in a manner deviating from the fixed part 170, the movable part 171 can have a tendency to move around the fixed part 170, and then when the movable part 171 moves around the fixed part 170, the movable part 171 can lock and / or unlock the center piece 15.

[0128] In some examples, the driving portion 172 can be deformed and restored. Specifically, the driving portion 172 can be a spring.

[0129] See also Fig.10 In some examples, the end of the driving portion 172 close to the movable portion 171 may be an end having a curved surface, wherein the curved surface may be smooth. That is, the end of the driving portion 172 abutting against the movable portion 171 may be a smooth curved surface. Specifically, in some examples, the driving portion 172 may be composed of a spring and a spherical ball disposed at one end of the spring close to the movable portion 171. In this case, when the driving portion 172 acts on the movable portion 171, the spherical ball can enable the movable portion 171 to rotate more smoothly relative to the driving portion 172.

[0130] In some examples, the second locking portion 17 may be integrally formed, the fixed portion 170 may be a portion of the second locking portion 17 fixed to the second support member 14 of the support structure 10, and the movable portion 171 may be another portion of the second locking portion 17 movable on the first support member 13 of the support structure 10. In this case, the second locking portion 17 can be easily processed.

[0131] In some examples, the second locking portion 17 may not be integrally formed, and the fixed portion 170 and the movable portion 171 may be disposed in the first support member 13. The fixed portion 170 may be a component fixed to the support structure 10, such as a round shaft, etc.; the movable portion 171 may be a component movable on the first support member 13. In this case, see Fig. 9 The combination of the movable portion 171 and the fixed portion 170 may mean that the movable portion 171 can be movably sleeved on the fixed portion 170 .

[0132] See also Figure 8B In some examples, the combination of the movable portion 171 and the fixed portion 170 may refer to the combination of the movable portion 171 and the fixed portion 170 via the connection between the driving portion 172 .

[0133] In some examples, the relatively stable state of the movable part 171 when it moves on the support structure 10 may mean that after the splitting and combining device 1 is used to complete the splitting and combining assembly 2, the force provided to the movable part 171 by the fixed part 170 or the force provided to the movable part 171 by the driving part 172 can restore the movable part 171 to its initial state; when the driving part 172 provides the movable part 171 with a force, relative sliding perpendicular to the plane in which the movable part 171 rotates around the fixed part 170 may not occur between the fixed part 170 and the movable part 171. In this case, the splitting and combining device 1 can be used for multiple splitting and combining.

[0134] It should be noted that, in some examples, multiple opening and closing of the opening and closing device 1 may cause the movable portion 171 to rotate multiple times, so that the movable portion 171 may apply additional force to the fixed portion 170, and the fixed portion 170 can release this additional force. In this case, the opening and closing device 1 can be used for multiple opening and closing.

[0135] In some examples, the center piece 15 may further include a locking region 154, and the movable portion 171 may act on the locking region 154 to enable the second locking portion 17 to lock and / or unlock the center piece 15. In this case, the second locking portion 17 may lock and / or unlock the center piece 15.

[0136] In some examples, the locking area 154 can be formed by machining a plurality of pre-designed tracks in the middle portion of the center piece 15, and the movable portion 171 can move along the plurality of tracks of the locking area 154. In this case, the movable portion 171 can be facilitated to lock and / or unlock the center piece 15.

[0137] Fig.11A is a schematic diagram showing that the movable portion 171 involved in the present disclosure is in a fully unlocked state in the locking area 154; Fig. 11B is a schematic diagram showing that the movable portion 171 involved in the present disclosure is in a preliminary locking state in the locking area 154; Fig. 11C is a schematic diagram showing that the movable portion 171 involved in the present disclosure is in a completely locked state in the locking area 154; Fig.11D is a schematic diagram showing that the movable portion 171 involved in the present disclosure is in a preliminary unlocking state in the locking area 154; Fig.11E is a schematic diagram of a stepped structure 155 between adjacent tracks involved in the present disclosure.

[0138] It should be understood that in FIG. 11A to FIG. 11D In order to make the drawings clearer, some identical parts are not marked repeatedly, and some parts that may cause misunderstanding are omitted.

[0139] See also Fig.11A In some examples, the locking area 154 may include a first track 1541, a second track 1542, a third track 1543, and a fourth track 1544. In some examples, the first track 1541, the second track 1542, the third track 1543, and the fourth track 1544 may be connected in sequence to form a complete loop.

[0140] See also Fig.11E In some examples, the locking area 154 may have a stepped structure 155 at the connection between at least one pair of adjacent tracks. Specifically, for example, the second track 1542 may be recessed to a certain depth toward the inside of the center piece 15 relative to the first track 1541, thereby forming a stepped structure 155 at the connection between the first track 1541 and the second track 1542. In some examples, the movable portion 171 may be closely attached to multiple tracks of the locking area 154 in the inner direction of the center piece 15. In this case, after the movable portion 171 passes through the stepped structure 155, it will not be able to reverse through the stepped structure 155 and return to the previous track, that is, under the dual effects of the stepped structure 155 and the movable portion 171 closely attached to multiple tracks of the locking area 154 in the inner direction of the center piece 15, the movable portion 171 can move in sequence (that is, unidirectionally) between the multiple tracks.

[0141] In some examples, the locking area 154 has a step-like structure 155 at the connection between adjacent tracks. In this case, after the splitting and combining device 1 performs multiple splitting and combining operations, the tendency of the movable part 171 to move to a vertical position may weaken or even disappear. At this time, the movable part 171 can move in the loop formed by the multiple tracks through the guidance of the step-like structure 155 between each pair of adjacent tracks.

[0142] In some examples, the locking area 154 has a stepped structure 155 at the connection between the second track 1542 and the third track 1543, the connection between the third track 1543 and the fourth track 1544, and the connection between the fourth track 1544 and the first track 1541. In this case, the movable portion 171 can move along the first track 1541 without entering the fourth track 1544 when the assembly 2 is pressed down for the first time; in addition, the movable portion 171 can move along the third track 1543 without entering the second track 1542 and move from the third track 1543 to the fourth track 1544 when the assembly 2 is pressed down for the second time.

[0143] 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 portion 171, 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 portion 171.

[0144] See also Fig. 11B In some examples, the third track 1543 may have a first fixed position 1543a. In some examples, the first fixed position 1543a may be formed by bending the inner side of the third track 1543 in the insertion direction D1. In some examples, the movable portion 171 may be stably stationary at the first fixed position 1543a. In this case, when the movable portion 171 moves to the first fixed position 1543a in a plurality of tracks, it can be stably stationary at the first fixed position 1543a, thereby enabling the movable portion 171 to lock the center piece 15.

[0145] See also Fig. 11B In some examples, the first track 1541 may have a second fixed position 1541a. In some examples, the second fixed position 1541a may be formed by bending the outer side of the first track 1541 in the insertion direction D1. In some examples, the movable portion 171 may be stably stationary at the second fixed position 1541a. In this case, when the movable portion 171 moves to the second fixed position 1541a in a plurality of tracks, it can be stably stationary at the second fixed position 1541a, thereby enabling the movable portion 171 to unlock the center piece 15.

[0146] See also Fig.11A In some examples, before the assembly 2 is pressed down on the center piece 15 for the first time, the movable portion 171 can be stationary at the second fixed position 1541a, and the movable portion 171 does not lock the center piece 15 at this time.

[0147] Combination Fig.11A , Fig. 11B and Fig.11E In some examples, during the first pressing of the assembly 2 on the center piece 15, the fixing member 21 can push the center piece 15 to move in the insertion direction D1, and the movable portion 171 stationary at the second fixing position 1541a can move along the first track 1541 under the action of the stepped structure 155 at the connection between the fourth track 1544 and the first track 1541. At the same time, the movable portion 171 will deviate from the original vertical position under the action of the first track 1541 and has a tendency to move to the vertical position. Therefore, when the movable portion 171 passes through the connection between the first track 1541 and the second track 1542, it will quickly move to the vertical position to abut against the outer side of the second track 1542. In some examples, when the movable portion 171 passes through the connection between the first track 1541 and the second track 1542, it will quickly move to the vertical position to abut against the outer side of the second track 1542. In this case, the movable portion 171 can be moved from the first track 1541 to the second track 1542.

[0148] In some examples, the connection point between the fourth track 1544 and the inner side of the first track 1541 may deviate from the fixed portion 170 in the direction of the fourth track 1544. When the assembly 2 is pressed down on the center piece 15 for the first time, the movable portion 171 may abut against the inner side of the first track 1541 during the movement of the center piece 15 in the insertion direction D1, but may not abut against the inner side of the fourth track 1544. At this time, the locking area 154 may not have the stepped structure 155 at the connection between the fourth track 1544 and the first track 1541. In this case, when the assembly 2 is pressed down for the first time, the movable portion 171 can move along the first track 1541 without entering the fourth track 1544, and the structure of the locking area 154 can be simplified.

[0149] Combination Fig. 11B and Fig. 11C In some examples, after the first downward pressure is completed and the force of the first downward pressure is removed, the elastic structure 12 can act on the central piece 15 so that the central piece 15 can move in the withdrawal direction D2. During the movement of the central piece 15 in the withdrawal direction D2, the movable portion 171 can move from the second track 1542 to the third track 1543 and stop at the first fixed position 1543a of the third track 1543. In this case, the movable portion 171 can move from the second track 1542 to the third track 1543, and can lock the central piece 15.

[0150] In some examples, after the separation and combination device 1 is used for multiple separation and combination operations, the tendency of the movable portion 171 to move toward a vertical position may weaken or even disappear. At this time, due to the presence of a stepped structure 155 at the connection between the first track 1541 and the second track 1542, the movable portion 171 can also move toward a vertical position under the guidance of the stepped structure 155 and the second track 1542.

[0151] In some examples, if the movable portion 171 still has a tendency to move to a vertical position after the splitting and combining device 1 undergoes multiple splitting and combining operations, the locking area 154 may not have a stepped structure 155 at the connection between the first track 1541 and the second track 1542. In this case, the structure of the locking area 154 can be simplified.

[0152] Combination Fig. 11C , Fig.11D and Fig.11EIn some examples, during the second pressing process of the assembly 2 on the center piece 15, the fixing piece 21 can push the center piece 15 to move in the insertion direction D1, and the movable portion 171 stationary at the first fixed position 1543a can move along the third track 1543 under the action of the stepped structure 155 at the connection between the second track 1542 and the third track 1543. At the same time, the movable portion 171 will deviate from the original vertical position and have a tendency to move toward the vertical position. After the movable portion 171 passes through the stepped structure 155 at the connection between the third track 1543 and the fourth track 1544, the movable portion 171 can move from the third track 1543 to the fourth track 1544.

[0153] In some examples, the connection point between the outer sides of the second track 1542 and the third track 1543 may deviate from the fixed portion 170 in the direction of the second track 1542. When the assembly 2 is pressed down on the center piece 15 for the second time, the movable portion 171 may abut against the outer side of the third track 1543 during the movement of the center piece 15 in the insertion direction D1, but may not abut against the outer side of the second track 1542. At this time, the locking area 154 may not have the stepped structure 155 at the connection between the second track 1542 and the third track 1543. In this case, when the assembly 2 is pressed down for the second time, the movable portion 171 can move along the third track 1543 in the direction of the fourth track 1544 without entering the second track 1542, and the structure of the locking area 154 can be simplified.

[0154] In some examples, after the movable portion 171 passes through the connection between the third track 1543 and the fourth track 1544, since there may be a step-like structure 155 at the connection between the third track 1543 and the fourth track 1544, and the movable portion 171 has a tendency to move to a vertical position, the movable portion 171 will abut against the step-like structure 155 at the connection between the third track 1543 and the fourth track 1544, and cannot directly return from the fourth track 1544 to the third track 1543. In this case, the movable portion 171 can be moved from the third track 1543 to the fourth track 1544, and the movable portion 171 can unlock the center piece 15.

[0155] Combination Fig.11A , Fig.11D and Fig.11EIn some examples, after the second pressing is completed and the force of the second pressing is removed, the elastic structure 12 can act on the center piece 15 to make the center piece 15 move in the withdrawal direction D2. During the movement of the center piece 15 in the withdrawal direction D2, the movable part 171 can move from the fourth track 1544 to the first track 1541 under the guidance of the stepped structure 155 at the connection between the third track 1543 and the fourth track 1544 and the fourth track 1544, and stop at the second fixed position 1541a of the first track 1541. In this case, the movable part 171 can move from the fourth track 1544 to the first track 1541, and can return to the second fixed position 1541a.

[0156] In some examples, a modified example of the locking area 154 may be that the middle portion of the center piece 15 is protruded toward a side close to the support structure 10. In this case, the movable portion 171 can be facilitated to lock and / or unlock the center piece 15.

[0157] See also Fig. 9 In some examples, the movable portion 171 may include at least two sets of snap-fit ​​structures. In some examples, the snap-fit ​​structures may act on the modified examples of the locking area 154 to lock and / or unlock the center piece 15. In this case, the second locking portion 17 may lock and / or unlock the center piece 15 through the cooperation of the snap-fit ​​structure and the locking area 154. The snap-fit ​​structures may be at least two sets so that the splitting and combining device 1 may be split and combined multiple times.

[0158] In some examples, the snap-fit ​​structure may include an abutment angle 1711 and a snap angle 1712. Figure 7 In some examples, a modification of the locking region 154 may include a horizontal side 1545 and a vertical side 1546. In some examples, when the abutment angle 1711 abuts against the vertical side 1546 and the clamping angle 1712 abuts against the horizontal side 1545, the second locking portion 17 may lock the center piece 15. In addition, when the clamping angle 1712 abuts against the vertical side 1546 or the abutment angle 1711 abuts against the horizontal side 1545, the second locking portion 17 may unlock the center piece 15. In this case, by changing the abutting relationship of the clamping angle 1712 and the abutment angle 1711 with the horizontal side 1545 and the vertical side 1546, the locked and unlocked states of the second locking portion 17 and the center piece 15 can be switched.

[0159] In some examples, the horizontal side 1545 is a side of the modified example of the locking region 154 that is perpendicular to the insertion direction D1 , and the vertical side 1546 is a side of the modified example of the locking region 154 that is parallel to the insertion direction D1 .

[0160] In some examples, preferably, the movable portion 171 may include two sets of snap-fit ​​structures. In some examples, the two sets of snap-fit ​​structures may be symmetrical about the center of the fixed portion 170 .

[0161] In some examples, the abutment angle 1711 and the clamping angle 1712 may be of the same shape. In other examples, the abutment angle 1711 and the clamping angle 1712 may be of different shapes.

[0162] In some examples, the abutment angle 1711 and the clamping angle 1712 can be smooth rounded corners. In this case, the wear of the center piece 15 caused by the rotation of the movable part 171 can be reduced.

[0163] Fig. 12A It is a schematic diagram showing the initial state of some components of the splitting and combining device 1 involved in the present disclosure; Fig. 12B is a schematic diagram showing a preliminary locking state involved in the present disclosure; Fig. 12C is a schematic diagram showing a fully locked state involved in the present disclosure; Fig.12D is a schematic diagram showing a preliminary unlocking state involved in the present disclosure; Fig.12E is a schematic diagram showing a fully unlocked state involved in the present disclosure.

[0164] It should be noted that FIG. 12A to FIG. 12E The second locking portion 17 and the locking area 154 mentioned in the above respectively refer to a modification of the second locking portion 17 and a modification of the locking area 154 in which the driving portion 172 provides a force to the movable portion 171. In addition, FIG. 12A to FIG. 12E The embodiment in the figure only shows the status of some parts of the splitting and combining device 1 involved in the process of splitting and combining the assembly 2. In order to better show how the first locking part 16 locks the fixing member 21, some parts (such as the elastic structure 12 and the separating member 20) and lines that may cause obstruction or misunderstanding are omitted, and the same parts are not repeatedly marked. In addition, FIG. 12A to FIG. 12E The fixing member 21 shown in the figure only shows the part where the fixing member 21 is locked with the first locking portion 16, and does not mean that the fixing member 21 and the separating member 20 are not combined or separated during the separation and combination process.

[0165] In some examples, the splitting and combining device 1 of the present disclosure can be FIG. 12A to FIG. 12E Sequential separation and assembly of assembly 2. FIG. 12A to FIG. 12E , describe in detail the process of separating and combining assembly 2.

[0166] See also Fig. 12A In some examples, in the initial state, the end of the first locking portion 16 away from the assembly 2 can be exposed outside the first limiting portion 152 in the direction of the first support member 13, and the driving portion 172 can deviate from the fixing portion 170 in the direction close to the center member 15 and abut against the corner 1712 of the first set of snap-fit ​​structures, and the corner 1712 of the first set of snap-fit ​​structures can abut against the vertical side 1546.

[0167] See also Fig. 12B In some examples, in the initial locking state, one end of the first locking portion 16 close to the assembly 2 can be partially exposed outside the first limiting portion 152 and abut against the third groove 211 of the fixing member 21 in the assembly 2, and the end of the first locking portion 16 away from the assembly 2 can contact the protrusion 101, the clamping corner 1712 of the first set of clamping structures can abut against the horizontal side 1545, and the driving portion 172 can abut against the clamping corner 1712 of the first set of clamping structures.

[0168] See also Fig. 12A and Fig. 12B In some examples, the first pressing of the assembly 2 on the center piece 15 can make the splitting and combining device 1 change from the initial state to the preliminary locking state. In this process, the center piece 15 can move in the insertion direction D1 under the push of the fixing piece 21. When the center piece 15 moves in the insertion direction D1, the first locking portion 16 can move toward the end of the first limiting portion 152 close to the assembly 2 under the action of the protrusion 101 of the first support piece 13 to abut against the third groove 211 of the fixing piece 21; at the same time, because the movable portion 171 has a tendency to rotate in the rotation direction D3 under the action of the driving portion 172, after the center piece 15 moves in the insertion direction D1 until the horizontal side 1545 is lower than the clamping angle 1712 of the first set of clamping structures, the clamping angle 1712 of the first set of clamping structures can be changed from abutting against the vertical side 1546 to abutting against the horizontal side 1545. In this case, the splitting and combining device 1 can be changed from the initial state to the preliminary locking state.

[0169] It should be noted that the initial locking state may be transient. Specifically, since the elastic structure 12 is compressed after the center piece 15 moves in the insertion direction D1 , the center piece 15 tends to move in the withdrawal direction D2 under the action of the elastic structure 12 .

[0170] See also Fig. 12C In some examples, in the fully locked state, the end of the first locking portion 16 close to the assembly 2 can be partially exposed outside the first limiting portion 152 and abut against the third groove 211 of the fixing member 21 in the assembly 2, the end of the first locking portion 16 away from the assembly 2 can contact the protrusion 101, the clamping angle 1712 of the first set of clamping structures can abut against the horizontal side 1545, the abutting angle 1711 of the first set of clamping structures can abut against the vertical side 1546, and the driving portion 172 can abut against the abutting angle 1711 of the first set of clamping structures. In this case, the fixing member 21 is fixed to the separation and combination device 1, so that the separation member 20 in the assembly 2 can be replaced.

[0171] See also Fig. 12B and Fig. 12CIn some examples, the elastic structure 12 acts on the center piece 15 to enable the separation and combination device 1 to be transferred from the preliminary locking state to the fully locked state. In this process, the end of the first locking portion 16 close to the assembly 2 can remain partially exposed outside the first limiting portion 152 and abut against the third groove 211 of the fixing member 21 in the assembly 2, and the end of the first locking portion 16 away from the assembly 2 can remain in contact with the protrusion 101. Since the center piece 15 moves in the insertion direction D1 during the first downward pressure, the elastic structure 12 can be compressed. Therefore, after the preliminary locking is completed, the center piece 15 can move in the withdrawal direction D2 under the action of the elastic structure 12, and the movable portion 171 can rotate in the rotation direction D3 under the driving action of the center piece 15. Since the driving portion 172 can be elastic, the abutment angle 1711 of the first group of clamping structures can compress the driving portion 172 so as to slide over the driving portion 172 (see Fig. 12C ), whereby the first set of clamping structures' clamping angles 1712 can abut against the horizontal side 1545, the first set of clamping structures' abutting angles 1711 can abut against the vertical side 1546, and the driving portion 172 can abut against the first set of clamping structures' abutting angles 1711. In this case, the splitting and combining device 1 can be turned from a preliminary locking state to a fully locked state.

[0172] In some examples, replacing the separator 20 in the assembly 2 may mean that in a completely locked state, the separator 20 in the assembly 2 may be taken out (e.g., pulled out or twisted out), so that the separator 20 can be separated from the assembly 2, and a new separator 20 can be combined with the fixing member 21 to form the assembly 2. In addition, during the process of replacing the separator 20, the user only needs to touch the separator 20 and does not need to touch other components. Thus, work efficiency can be improved, use is convenient, and hospital infection can be reduced.

[0173] See also Fig.12D In some examples, in the initial unlocking state, the end of the first locking portion 16 close to the assembly 2 can be partially exposed outside the first limiting portion 152 and abut against the third groove 211 of the fixing member 21 in the assembly 2, the end of the first locking portion 16 away from the assembly 2 can contact the protrusion 101, the abutting angle 1711 of the first set of clamping structures can abut against the horizontal side 1545, and the driving portion 172 can abut against the abutting angle 1711 of the first set of clamping structures. In this case, the second locking portion 17 can unlock the center piece 15.

[0174] See also Fig. 12C and Fig.12DIn some examples, pressing down the assembly 2 on the center piece 15 for the second time can make the separation and combination device 1 change from the completely locked state to the preliminary unlocked state. In this process, when the separation piece 20 is replaced, the separation piece 20 inserted into the fixing piece 21 and the fixing piece 21 can be reassembled into the assembly 2, and the center piece 15 can move in the insertion direction D1 under the push of the fixing piece 21. The center piece 15 can move in the insertion direction D1 until the horizontal side 1545 is lower than the abutment angle 1711 of the first group of clamping structures, and the movable part 171 can be rotated in the rotation direction D3 by a certain angle under the action of the driving part 172, so that the abutment angle 1711 of the first group of clamping structures can be changed from abutting the vertical side 1546 to abutting the horizontal side 1545 (see Fig.12D ). In this case, the splitting and combining device 1 can be turned from the fully locked state to the preliminary unlocked state.

[0175] It should be noted that the initial unlocking state may be transient. Specifically, since the elastic structure 12 is compressed after the center piece 15 moves in the insertion direction D1 , the center piece 15 tends to move in the withdrawal direction D2 under the action of the elastic structure 12 .

[0176] See also Fig.12E In some examples, in the fully unlocked state, the end of the first locking portion 16 close to the assembly 2 can be partially exposed outside the first limiting portion 152 and abut against the third groove 211 of the fixing member 21 in the assembly 2, the end of the first locking portion 16 away from the assembly 2 can be separated from the contact with the protrusion 101, and the clamping angle 1712 of the second set of clamping structures can abut against the vertical side 1546 under the action of the driving portion 172. In this case, the assembly 2 can be pulled out of the separation and combination device 1.

[0177] See also Fig.12D and Fig.12E In some examples, the elastic structure 12 acts on the center piece 15 to enable the separation and combination device 1 to be transferred from a preliminary unlocking state to a completely unlocking state. During this process, the end of the first locking portion 16 close to the assembly 2 can remain partially exposed outside the first limiting portion 152 and abut against the third groove 211 of the fixing member 21 in the assembly 2, and the end of the first locking portion 16 away from the assembly 2 can be transferred from contact with the protrusion 101 to disengagement from the protrusion 101.

[0178] Specifically, during the movement of the center piece 15 in the withdrawal direction D2, the first locking portion 16 can be maintained in the first limiting portion 152 and gradually exceed the protrusion 101. Since the movement of the center piece 15 in the insertion direction D1 during the second downward pressure can compress the elastic structure 12, after the initial unlocking is completed, the center piece 15 can move in the withdrawal direction D2 under the action of the elastic structure 12; at the same time, since the abutment angle 1711 of the first set of snap-fit ​​structures can abut the horizontal side 1545, the movable portion 171 can rotate in the rotation direction D3 driven by the center piece 15, and since the driving portion 172 can be elastic, the clamping angle 1712 of the second set of clamping structures can compress the driving portion 172 so as to slide over the driving portion 172 until the driving portion 172 can be between the clamping angle 1712 of the second set of clamping structures and the abutment angle 1711 of the second set of clamping structures (see Fig.12E When the driving portion 172 passes through the clamping angle 1712 of the second clamping structure, the driving portion 172 can rebound and act on the clamping angle 1712 of the second clamping structure, so that the movable portion 171 can continue to rotate in the rotation direction D3 by a certain angle until the clamping angle 1712 of the second clamping structure abuts against the vertical side 1546 (see Fig.12E ). In this case, the splitting and combining device 1 can be changed from the preliminary unlocking state to the fully unlocking state.

[0179] Fig.13 is a flow chart showing a method of separating and combining the assembly 2 according to the present disclosure.

[0180] In this embodiment, see Fig.13 The method for separating and combining the medical assembly 2 may include: pressing the assembly 2 on the device 1 for the first time (step S100); replacing the separation element 20 in the assembly 2 (step S200); pressing the assembly 2 on the device 1 for the second time (step S300); and pulling out the assembly 2 (step S400).

[0181] In some examples, in step S100, pressing down the assembly 2 on the device 1 for the first time specifically refers to placing the assembly 2 to be separated and combined on the center piece 15, and pressing down the separation piece 20 for the first time to press down the assembly 2 so that the fixing piece 21 can push the center piece 15 to move together in the insertion direction D1, and at this time the first locking portion 16 can lock the fixing piece 21 so that the fixing piece 21 can be locked with the device 1; when the first pressing force is removed, the elastic structure 12 can act on the center piece 15 to make the center piece 15 rebound, that is, the center piece 15 can move in the withdrawal direction D2, and at this time the second locking portion 17 can lock the center piece 15. In this case, the first locking portion 16 can lock the fixing piece 21, and the second locking portion 17 can lock the center piece 15. In this way, a firm connection can be formed between the assembly 2 and the separation and combination device 1.

[0182] In some examples, in step S200, replacing the separator 20 in the assembly 2 may specifically refer to taking out (such as pulling out or unscrewing) the separator 20 in the assembly 2, so that the separator 20 can be separated from the assembly 2, and the new separator 20 can be combined with the fixing member 21. In addition, during the process of replacing the separator 20, the user only needs to touch the separator 20 and does not need to touch other components. In this way, work efficiency can be improved, use is convenient, and hospital infection can be reduced.

[0183] In some examples, in step S300, the second pressing of the assembly 2 on the device 1 may specifically refer to pressing down the new separation piece 20 in step S200, at which time the new separation piece 20 and the fixing piece 21 can be reassembled into the assembly 2; the second pressing of the new separation piece 20 presses down the assembly 2 so that the fixing piece 21 can push the center piece 15 to move in the insertion direction D1, and the second locking part 17 can unlock the center piece 15; when the second pressing force is removed, the elastic structure 12 can act on the center piece 15 to make the center piece 15 rebound, that is, the center piece 15 can move in the withdrawal direction D2, and the first locking part 16 can unlock the fixing piece 21 so that the fixing piece 21 can be unlocked from the device 1. In this case, the second locking part 17 can unlock the center piece 15, and the first locking part 16 can unlock the fixing piece 21. In this way, the assembly 2 can be separated from the separation and combination device 1.

[0184] In some examples, in step S400, extracting the assembly 2 may specifically mean that the first locking portion 16 may unlock the fixing member 21 after step S300, and then the separating member 20 may be extracted to drive the fixing member 21 and then extract the assembly 2. In this case, hospital infection can be reduced.

[0185] It should be noted that, during the process of locking the fixing member 21 and the device 1, the assembly 2 and the central member 15 can rebound under the action of the elastic structure 12; during the process of unlocking the fixing member 21 and the device 1, the assembly 2 and the central member 15 can rebound under the action of the elastic structure 12. In this case, the second locking portion 17 can lock and / or unlock the central member 15 through the rebound action of the elastic structure 12.

[0186] In some examples, by separating and combining the assembly 2 in steps S100, S200, S300, and S400, work efficiency can be improved, usage is convenient, and hospital infection can be reduced.

[0187] Although the present disclosure is specifically described above in conjunction with the accompanying drawings and examples, it is to be understood that the above description does not limit the present disclosure in any form. 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.
