Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to a consumable cartridge mounting base and a waste collection device. Background Art

[0002] During a specific surgical procedure, wastes of types such as liquids, semi - solids, and solids will inevitably be generated, specifically including human fluids such as blood, and perfusion solutions introduced into the surgical site during the surgical procedure. Additionally, solid and semi - solid wastes generated during the surgical procedure include tissue fragments and small pieces of surgical materials that may remain in the human body part. Ideally, once the wastes are generated, they will be collected so as not to contaminate the surgical site and not become biological hazards in the operating room or other locations where the surgical procedure is performed.

[0003] In the prior art, there are various waste collection systems available for medical staff to collect the wastes generated during a surgical procedure during or after the surgery. Its principle is mainly to generate a suction force through a vacuum source to suck the wastes generated at the surgical site into a specific collection container. That is, after the system is started, the suction force generated by the vacuum source reaches the surgical site, and thus the wastes are sucked and flow into a specific collection container through the pipeline in contact with the surgical site.

[0004] For example, the NEPTUNE waste collection device produced by Stryker in the prior art, see the attached Figure 1 attachment Figure 1 is a schematic structural diagram of a waste collection device in the prior art. The waste collection device 1 includes a moving unit 11, a vacuum source 12, a consumable cartridge 14, and a waste collection tank 13. In this technical solution, since the pipeline 15 in contact with the surgical site is connected through a detachable consumable cartridge 14 and a waste collection tank 13. The moving unit 11 can make the waste collection device 1 more flexible in position during use. By using a disposable consumable cartridge 14, it is not necessary to disinfect this device anymore, and only the waste collection tank 13 needs to be cleaned and disinfected, which can maximize the risk of waste contamination. See Figure 1, in the prior art, when using the consumable cartridge 14, it needs to be inserted into the corresponding consumable cartridge jack of the waste collection device 1. This method may cause the consumable cartridge 14 to accidentally fall off during use, resulting in pollution of the operating room and also contaminating the waste collection device. To prevent the consumable cartridge 14 from falling off, the prior art provides a fixing structure for the consumable cartridge. The operator needs to rotate the consumable cartridge 14 so that it can be fixed in the socket of the waste collection device 1. Similarly, after use, the operator needs to manually rotate and remove the consumable cartridge 14. This structure also requires the operator to manually lock the consumable cartridge 14, and when removing the consumable cartridge 14, the operator also needs to manually remove it. The solution of the prior art not only increases the manual operation steps, but also easily causes difficulties in removal due to different manual operation forces, or fluid leakage due to excessive force, thereby increasing the risk of contaminating the device.

The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "inside", "outside", "side", etc., are only references to the directions of the attached drawings. Therefore, the directional terms used are for explaining and understanding the present invention, rather than for limiting the present invention.

[0037] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0038] As Figure 10 In the illustrated embodiment, the consumable cartridge 1000 is connected to, preferably, plugged into a waste collection device 3000 for collecting medical waste. Specifically, as Figure 2 shown, the consumable cartridge 1000 is plugged into the consumable cartridge mounting base 2000 of the waste collection device 3000. As Figure 3As shown, the consumable cartridge mounting base 2000 includes: a base pedestal 2100, a locking structure 2300, and an operating member 2200. The base pedestal 2100 forms an installation entrance 2120 for accessing the consumable cartridge 1000; the locking structure 2300 is provided on the base pedestal 2100 and can be used to lock the consumable cartridge 1000 after the consumable cartridge 1000 is accessed, and can release the consumable cartridge 1000 after receiving a release operation; the operating member 2200 is connected to the locking structure 2300 and is used to perform the release operation on the locking structure 2300.

[0039] Specifically, in this example, the consumable cartridge 1000 is as Figure 2 - 3 shown, and the consumable cartridge 1000 is used for Figure 10 the waste collection device 3000 shown. In this embodiment, the consumable cartridge 1000 includes a vacuum source interface 1100, a waste connector 1200, and an external pipeline connector 1300. Among them, the external pipeline connector 1300 is used to introduce medical waste, and the external pipeline connector 1300 is connected to an external suction pipeline (not shown in the figure), and the external suction pipeline can be connected to a suction connector (not shown in the figure), and the suction connector can be a separate connector or attached to a surgical device. The suction force at the suction connector transports the waste generated during the medical process through the external suction pipeline to the waste connector 1200 and enters and is stored in the waste collection device 3000.

[0040] One end of the waste connector 1200 is in liquid connection with the external pipeline connector 1300 and is used to connect to the waste collection tank 3100 of the waste collection device 3000, so that medical waste enters the waste collection tank 3100 of the waste collection device 3000.

[0041] In addition, the consumable cartridge 1000 further includes a vacuum source connector 1100, which is used to connect to a vacuum source (not shown in the figure). The vacuum source can be provided inside the waste collection device 3000 or can be an external separate vacuum source. At the same time, the vacuum source connector 1100 is in gas connection with the waste collection tank 3100 to provide a suction force for the waste collection tank 3100, as Figure 10 shown.

[0042] In the embodiment of the present invention, the consumable cartridge 1000 shown in Figure 2 and Figure 3 is adopted. In addition to forming the installation entrance 2120 for accessing the consumable cartridge 1000, the base pedestal 2100 also forms a vacuum source socket 2110 for accessing the vacuum source connector 1100 of the consumable cartridge 1000. The installation entrance 2120 is used to access the waste connector 1200 of the consumable cartridge 1000. In addition, as Figure 3As shown, the base pedestal 2100 is further provided with a guiding interface 2500 which is provided with a guiding inclined surface for guiding the consumable cartridge 1000 to find the correct position and preventing the collision of the connector of the consumable cartridge 1000 at the same time.

[0043] See Figure 2 - 9 As shown, the locking structure 2300 includes: a locking piece 2310 and a transmission structure 2301. The transmission structure 2301 cooperates with the locking piece 2310 to drive the locking piece 2310 to perform locking and unlocking actions. Among them, the locking piece 2310 is movably arranged on the base pedestal 2100 and can move between a first position and a second position; after the consumable cartridge 1000 is inserted, when the locking piece 2310 is in the first position, as Figure 4 shown, the locking structure 2300 locks the consumable cartridge 1000; when the locking piece 2310 is in the second position, as Figure 5 shown, the locking structure 2300 releases the consumable cartridge 1000; the transmission structure 2301 cooperates with the locking piece 2310 to move the locking piece 2310 between the first position and the second position.

[0044] See Figure 3 - Figure 5 and Figure 9 , the locking piece 2310 further includes: a fastening port 2350 and an unlocking port 2360. The fastening port 2350 is arranged on the locking piece 2310 for locking the consumable cartridge 1000 when the locking piece 2310 is in the first position; the unlocking port 2360 is arranged on the locking piece 2310 and is adjacent to the fastening port 2350 for releasing the consumable cartridge 1000 when the locking piece 2310 is in the second position.

[0045] See Figure 2 - Figure 5 , the transmission structure 2301 is a cam, and the cam 2301 is rotatably arranged on the base pedestal 2100. The cam in this embodiment is a disc cam, which specifically includes a wheel disc 2302 and a transmission rod 2303. Among them, the wheel disc 2302 can rotate in the transmission window 2320 of the locking piece 2310, and the transmission window 2320 is arranged on the body of the locking piece 2310 to cooperate with the cam. In other embodiments, a moving cam or a cylindrical cam can be used, and the cooperation structure with the locking piece 2310 can also be changed correspondingly. When the wheel disc of the cam 2301 in this embodiment is in the locking position, the locking piece 2310 locks the waste connector 1200 of the consumable cartridge 1000. Preferably, a snap ring 1210 can be arranged on the waste connector 1200. When the locking piece 2310 is in the second position, the consumable cartridge 1000 is inserted. After the operator performs a locking operation through the operating member 2200, the wheel disc 2302 rotates to the locking position, the locking piece 2310 moves to the first position, and locks the consumable cartridge 1000 through the snap ring 1210.

[0046] In this embodiment, the operating component 2200 is a knob, and the knob is connected to the transmission rod 2303. An elastic component 2400 is arranged between the lock piece 2310 and the base pedestal 2100, and the elastic component 2400 is used to pull the lock piece 2310 to move. Specifically, when the wheel disc 2302 is in the unlocking position, it positions the lock piece 2310 at the second position. At this time, the wheel disc 2302 compresses the elastic component 2400 arranged between the lock piece 2310 and the base pedestal 2100, causing it to undergo elastic deformation. After inserting the consumable cartridge 1000 and the operator performs a locking operation through the operating component 2200, the wheel disc 2302 rotates to the locking position, and the lock piece 2310 is moved to the first position under the action of the elastic component 2400. At this time, the fastening port 2350 locks the consumable cartridge 1000 through the snap ring 1210. Similarly, after use, the operator rotates the operating component 2200 to make the wheel disc 2302 in the unlocking position. The wheel disc 2302 pushes the lock piece again to position the lock piece 2310 at the second position, and the fastening port 2350 moves outward. At this time, the waste connector 1200 is located in the unlocking port 2360, and the operator can easily pull out the consumable cartridge 1000. In this embodiment, the unlocking port 2360 and the fastening port 2350 are connected, and the diameter of the fastening port 2350 is smaller than the diameter of the unlocking port 2360. Specifically, the inner diameter of the unlocking port 2360 is larger than the outer diameter of the snap ring 1210, and the outer diameter of the snap ring 1210 is larger than the inner diameter of the fastening port 2350. In addition, the snap ring 1210 can be other structures, such as a card slot, spaced clamping blocks, etc.

[0047] See Figure 6 - Figure 9 , one end of the lock piece 2310 is located between the operating component 2200 and the mounting back plate 2130 of the base pedestal 2100, and slides on the moving track 2190. At the same time, the other end of the lock piece 2310 is inserted into the sliding slot 2191 of the consumable cartridge mounting base 2100. A first slot 2340 for placing the elastic component 2400 is arranged on the lock piece 2310, and a second elastic mounting member 2330 is provided. At the same time, a first elastic mounting member 2160 is arranged on the base pedestal 2100. The first elastic mounting member 2160 can be a metal rod or a screw that is later inserted into the sliding slot 2191. The second elastic mounting member 2330 is a sleeve rod integrally formed with the lock piece 2310. The elastic component 2400 is a spring with one end sleeved on the first elastic mounting member 2160 arranged on the base pedestal 2100 and the other end sleeved on the second elastic mounting member 2330 arranged on the lock piece 2310.

[0048] Further, the fastening port 2350 is provided with a guiding portion 2370 for guiding the insertion of the consumable cartridge 1000. In this embodiment, after the consumable cartridge 1000 is taken out, even if the turntable 2302 is in the locked position due to redundant operations, under the action of the elastic component 2400, the operator can directly insert the consumable cartridge 1000. The guiding portion 2370 is an opening in the shape of a frustum of a cone, which can guide the waste connector 1200 of the consumable cartridge 1000 to be inserted and automatically lock the consumable cartridge 1000 without first performing an unlocking operation.

[0049] See Figure 6 - Figure 8 , the cam 2301 is connected to the mounting back plate 2130 of the base pedestal 2100 through the jack 2170. Among them, the mounting back plate 2130 is further provided with a limiting recess 2180, which can limit the movement of the cam 2301 to prevent deviation during its movement. That is, a part of the turntable 2302 of the cam 2301 rotates within the limiting recess 2180, and the other part rotates within the transmission window 2320 of the locking piece 2310. At the same time, correspondingly, the mounting back plate 2130 is further provided with a second slot 2140 for accommodating the elastic component 2400.

[0050] See Figure 8 and Figure 9 , the base pedestal 2100 is provided with a guiding structure 2150 for guiding the movement of the locking piece 2310. Among them, the guiding structure 2150 cooperates with the first card slot 2340, and the first card slot 2340 passes through the guiding structure 2150. The surface width of the guiding structure 2150 is greater than the width of the first card slot 2340, and the inner surface width of the guiding structure 2150 is less than the width of the first card slot 2340, that is, the first card slot 2340 passes through the guiding structure 2150 and is limited in position.

[0051] In other embodiments, the vacuum source connector 1100 of the consumable cartridge 1000 can also be locked and unlocked through an additional locking structure.

[0052] Correspondingly, see Figure 10 , the present invention further provides a waste collection device 3000, which includes the above-mentioned consumable cartridge mounting base 2000.

[0053] Implementing the embodiments of the present invention has the following beneficial effects: The consumable cartridge mounting base in the embodiments of the present invention makes it more convenient to install and remove the consumable cartridge. At the same time, locking and unlocking the consumable cartridge do not require manual direct operation, thereby increasing the convenience of equipment use and avoiding the user from coming into too much contact with the used, contaminated, and waste-containing consumable cartridge. At the same time, it can effectively avoid the pollution risk caused by operation errors due to different manual forces.

[0054] The above-disclosed is only a preferred embodiment of the present invention. Of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
