Description

A consumable holder, a consumable box, and a waste collection device Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a consumable holder, a consumable box, and a waste collection device. Background Technology

[0002] During complex surgeries such as heart surgery, neurosurgery, or organ transplantation, various types of waste are frequently and extensively generated on the operating table. This waste includes not only natural bodily fluids such as blood and tissue fluid, but also irrigation solutions introduced during surgery to clean wounds and maintain a clear field of vision. Waste collection equipment allows medical staff to collect surgical waste generated during or after surgery.

[0003] Existing waste collection equipment typically uses a consumable cartridge to suck up waste, which is then filtered and enters a collection container. During use, a consumable holder is used to secure and connect the cartridge. The cartridge contains a valve to control liquid flow, and the holder has a flow channel that connects to the collection container. When the cartridge is inserted into the holder, the valve connects to the flow channel. Activating a negative pressure generator creates negative pressure within the collection container, opening the valve and drawing the liquid from the cartridge into the container. However, the flow channel in existing consumable holders is always open. Prolonged exposure can easily lead to liquid or gas leakage from the collection container, causing contamination, and other unidentified substances can easily fall into the container.

[0004] Summary of the Invention

[0005] In order to solve the problem that liquid or gas leakage from the collection container is easily caused by the consumable holder in the prior art, this invention provides a consumable holder, a consumable box, and a waste collection device that can achieve sealing when the consumable box is not connected, and can achieve normal gas-liquid communication when the consumable box is connected.

[0006] To solve the above-mentioned technical problems, the present invention provides a consumable holder for installing a consumable box, including a holder body, a connecting seat disposed in the holder body, and a first valve disposed in the connecting seat. The connecting seat can communicate with a collection container. The consumable box includes an insertion part and a connecting part disposed in the insertion part. The insertion part can be inserted into the holder body.

[0007] The first valve includes a fixed valve core and a movable valve body, and the movable valve body has a communication port.

[0008] When the insertion part is inserted into the seat body from the first direction, the connecting part communicates with the connecting port, and the connecting part drives the movable valve body to move in the first direction so that the connecting port is separated from the fixed valve core and the connecting port is connected to the conductive seat.

[0009] When the insertion part leaves the seat body in the opposite direction of the first direction, the movable valve body can move in the opposite direction of the first direction so that the communication port is close to the fixed valve core and the communication port is isolated from the conductor seat.

[0010] As an improvement to the above solution, the first valve further includes an elastic element and a fixed valve body, the fixed valve body being disposed in the conduction seat, and the elastic element being disposed between the fixed valve body and the movable valve body.

[0016] As an improvement to the above solution, a first inclined surface is provided between the first sealing groove and the sealing part, and a second inclined surface is provided on the inner edge of the communication port. The positions of the first inclined surface and the second inclined surface are corresponding, and the diameters of the first inclined surface and the second inclined surface gradually decrease along the first direction. The first inclined surface can abut against the second inclined surface.

[0017] As an improvement to the above solution, a sealing surface is further provided between the first inclined surface and the outer edge of the sealing part, and the sealing surface can abut against the outer edge of the connecting hole.

[0018] As an improvement to the above solution, the movable valve body further includes an abutment portion, which extends from the end of the sliding portion toward a direction away from the central axis of the sliding portion. The abutment portion is provided with a receiving groove, and the communication port is provided in the receiving groove. When the insertion portion is inserted into the seat body from the first direction, the communication portion can push the abutment portion to move from the first direction and make the communication portion communicate with the receiving groove.

[0019] As an improvement to the above solution, a limiting step is formed between the abutting part and the sliding part, one end of the elastic member abuts against the limiting step, and after the movable valve body moves in the first direction, the end of the limiting part can abut against the limiting step.

[0020] As an improvement to the above solution, the guide seat is provided with a fixing hole, and both the fixed valve body and the movable valve body are provided in the fixing hole. The fixed valve body also includes a fixing part, which is fixed in the fixing hole. One end of the elastic member abuts against the fixing part. When the insertion part is inserted into the seat body from the first direction, the connecting part can be inserted into the fixing hole from the first direction and push the movable valve body.

[0021] As an improvement to the above solution, the inner wall of the fixing hole is provided with a second sealing groove, and a second sealing ring is provided in the second sealing groove. After the connecting part is inserted into the fixing hole, the inner wall of the second sealing ring can abut against the outer wall of the connecting part.

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this document are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0044] Referring to Figures 1, 2, and 6, an embodiment of the present invention discloses a consumable holder 100 for fixing a consumable box 200. The consumable holder 100 includes a seat body 1, a connecting seat 2 disposed within the seat body 1, and a first valve 3 disposed within the connecting seat 2. The first valve 3 can control the opening and closing of the connecting seat 2. When the first valve 3 is open, the connecting seat 2 can communicate with a collection container 300, allowing gas to flow between the two, while liquid can enter the collection container 300 from the consumable box 200 through the connecting seat 2. The consumable box 200 includes an insertion part 4 and a connecting part 5 disposed within the insertion part 4. The seat body 1 has a perforated structure, allowing the insertion part 4 to be inserted into the seat body 1. In this embodiment of the present invention, the first valve 3 remains closed before the insertion part 4 is inserted into the seat body 1, and automatically opens after the insertion part 4 is inserted into the seat body 1.

[0045] Specifically, referring to Figures 3 and 6, the first valve 3 includes a fixed valve core 31 and a movable valve body 32, wherein the movable valve body 32 has a communication port 321. When the first valve 3 is closed, the fixed valve core 31 can close the communication port 321. After the fixed valve core 31 moves away from the communication port 321, the communication port 321 opens, thereby opening the first valve 3.

[0046] Referring to Figure 3, in one scenario, when the insertion part 4 is inserted into the seat 1 from the first direction, the connecting part 5 first contacts and connects with the connecting port 321 to form a connection. As the connecting part 5 continues to move, it pushes the movable valve body 32 to move in the first direction. At this time, the connecting port 321 separates from the fixed valve core 31. Since the first valve 3 was in a closed state before the insertion part 4 was inserted, the fixed valve core 31 blocks the connecting port 321, forming a blockage. After the insertion part 4 is inserted, the connecting port 321 separates from the fixed valve core 31, opening the connecting port 321 and allowing it to connect with the conductive seat 2. That is, after the insertion part 4 is inserted into the seat 1 from the first direction, the first valve 3 automatically opens, and the connecting port 321 connects with the conductive seat 2, thereby connecting the consumable box 200 with the collection container 300. After connection, the negative pressure generated by the system allows the liquid and gas in the consumable box 200 to enter the collection container 300.

[0047] Referring to Figure 5, in one scenario, when the insertion part 4 leaves the seat 1 from the opposite direction of the first direction, it loses the pushing force of the connecting part 5 in the first direction. The movable valve body 32 can move in the opposite direction of the first direction. At this time, the connecting port 321 approaches the fixed valve core 31, and the fixed valve core 31 blocks the connecting port 321, isolating the connecting port 321 from the conductive seat 2, thereby disconnecting the connection between the consumable box 200 and the collection container 300. At the same time, since the connecting port 321 is blocked and will not be in an open state, liquid or gas in the collection container 300 cannot leak out through the connecting port 321, and external unidentified objects will not enter the collection container 300 through the connecting port 321, thus completely isolating the space inside the collection container 300.

[0048] For example, the first direction is the vertically downward direction, that is, the insertion part 4 is inserted vertically downward into the base 1, while the opposite direction of the first direction is the vertically upward direction.

[0049] The beneficial effects of the embodiments of the present invention are as follows:

[0050] In this embodiment of the invention, the consumable holder 100 is provided with a connecting seat 2 and a first valve 3 disposed within the connecting seat 2. The first valve 3 includes a fixed valve core 31 and a movable valve body 32. When the consumable box 200 is inserted into the consumable holder 100, the connecting portion 5 of the consumable box 200 can push the movable valve body 32 to move, thereby connecting the connecting portion 5 with the connecting port 321 within the movable valve body 32. This allows communication with the connecting seat 2 through the connecting port 321, enabling communication with the collection container 300. After use, when the consumable box 200 is pulled out of the consumable holder 100, the connecting port 321 is isolated from the connecting seat 2, preventing liquid or gas leakage from the collection container 300 and preventing unidentified objects from entering the collection container 300, thus achieving a sealing and isolation effect.

[0051] Referring to Figure 3, in some embodiments, the first valve 3 further includes an elastic element 33 and a fixed valve body 34. The fixed valve body 34 is disposed in the guide seat 2, and the elastic element 33 is disposed between the fixed valve body 34 and the movable valve body 32. The fixed valve body 34 is stationary relative to the guide seat 2, and the fixed valve core 31 is stationary relative to the guide seat 2. When the movable valve body 32 moves in the first direction, the pushing force of the connecting part 5 is greater than the elastic force of the elastic element 33. The movable valve body 32 moves closer to the fixed valve body 34, causing the elastic element 33 to be in a compressed state. After the connecting part 5 is inserted, the movable valve body 32 is fixed, the elastic element 33 is in a compressed state, and the connecting port 321 is opened. When the insertion part 4 leaves the seat 1 in the opposite direction of the first direction, the movable valve body 32 loses the pushing force of the connecting part 5. Under the action of the elastic restoring force, the elastic element 33 can drive the movable valve body 32 to move in the opposite direction of the first direction, thereby pushing the movable valve body 32 to the initial position, so that the fixed valve core 31 blocks the connecting port 321. The elastic element 33 can be a spring, elastic sponge, or other compressible and elastic components.

[0052] Referring to Figure 3, in some embodiments, in order to form a seal on the communication port 321, the fixed valve core 31 is provided with a sealing part 311. The sealing part 311 is located at the upper part of the fixed valve core 31. The sealing part 311 extends from the side wall of the fixed valve core 31 in a direction away from the central axis of the fixed valve core 31 to form a larger covering surface. The outer diameter of the sealing part 311 is larger than the maximum diameter of the communication port 321, so that when the sealing part 311 abuts against the communication port 321, it can cover and seal the communication port 321.

[0053] In some embodiments, the movable valve body 32 further includes a sliding portion 322, which has a communicating hole 3221. The communicating port 321 is located at one end of the communicating hole 3221 and communicates with it. The communicating hole 3221 allows the communicating port 321 to communicate with the outlet of the guide seat 2. The fixed valve body 34 includes a guide portion 341, which has a guide hole 3411. The sliding portion 322 passes through the guide hole 3411. When the movable valve body 32 moves in the first direction or the opposite direction, the sliding portion 322 can move within the guide hole 3411. The guide hole 3411 both guides the sliding portion 322 and communicates with the communicating hole 3221, allowing the communicating port 321 to communicate with the outlet of the guide seat 2 through the guide hole 3411.

[0054] Referring to Figure 6, in some embodiments, to achieve a tighter seal on the connecting port 321, the side wall of the fixed valve core 31 is further provided with a first sealing groove 312, and a first sealing ring 35 is provided on the first sealing groove 312. The first sealing ring 35 can abut against the side wall of the connecting hole 3221. In scenarios where the consumable box 200 does not need to be inserted, the sealing part 311 and the first sealing ring 35 can form a tight seal on the connecting port 321 to prevent liquid or gas in the collection container 300 from overflowing, thus providing a better sealing and protection effect.

[0055] Further, referring to Figure 6, a first inclined surface 313 is provided between the first sealing groove 312 and the sealing part 311, and a second inclined surface 323 is provided on the inner edge of the connecting opening 321. The positions of the first inclined surface 313 and the second inclined surface 323 correspond to each other. The diameters of the first inclined surface 313 and the second inclined surface 323 gradually decrease along the first direction. When sealing the connecting opening 321, the first inclined surface 313 can abut against the second inclined surface 323. By setting the first inclined surface 313 and the second inclined surface 323, the first sealing ring 35 can easily enter the connecting hole 3221 using the second inclined surface 323, and the abutment between the inclined surfaces does not require high fitting precision. Even if there is a processing error between the sealing part 311 and the connecting hole 3221, it is easy for the sealing part 311 to abut against the edge of the connecting opening 321, thereby forming a seamless seal.

[0056] Furthermore, a sealing surface 314 is provided between the first inclined surface 313 and the outer edge of the sealing part 311. The sealing surface 314 can abut against the outer edge of the connecting hole 3221, and the sealing surface 314 can ensure a complete sealing of the connecting hole 321.

[0057] Referring to Figure 4, in some embodiments, the movable valve body 32 further includes an abutment portion 324, which extends from the end of the sliding portion 322 in a direction away from the central axis of the sliding portion 322. The abutment portion 324 is located at the end of the sliding portion 322 away from the fixed valve body 34, and the connecting portion 5, after insertion, abuts against the abutment portion 324. The abutment portion 324 has a receiving groove 3241, and the interior of the connecting portion 5 communicates with the receiving groove 3241, with the connecting port 321 located in the receiving groove 3241. Therefore, in some embodiments, the receiving groove 3241, the connecting hole 3221, and the guide hole 3411 form a channel connecting the consumable box 200 and the outlet portion of the guide seat 2. When the insertion part 4 is inserted into the seat 1 from the first direction, the connecting part 5 can push the abutment part 324 to move from the first direction and make the connecting part 5 communicate with the receiving groove 3241.

[0058] Furthermore, a limiting step 36 is formed between the abutting portion 324 and the sliding portion 322. One end of the elastic member 33 abuts against the limiting step 36, thus the elastic member 33 can push the movable valve body 32 using its elastic restoring force. The limiting step 36 can restrict the movement stroke of the movable valve body 32. After the movable valve body 32 moves a certain distance in the first direction, the end of the limiting portion can abut against the limiting step 36. The limiting step 36 can restrict the continued movement of the movable valve body 32 in the first direction, thereby achieving a limiting effect.

[0059] In some embodiments, the guide seat 2 is provided with a fixing hole 21, and both the fixed valve body 34 and the movable valve body 32 are disposed within the fixing hole 21, with the movable valve body 32 moving within the fixing hole 21. The fixed valve body 34 further includes a fixing part 342, which is fixed within the fixing hole 21. The fixing hole 21 provides a fixing function for the fixed valve body 34 and can resist the elastic force from the elastic member 33. When the insertion part 4 is inserted into the seat 1 from the first direction, the communicating part 5 can be inserted into the fixing hole 21 from the first direction and push the movable valve body 32. One end of the elastic member 33 abuts against the fixing part 342. Therefore, in some embodiments, one end of the elastic member 33 abuts against the limiting step 36, and the other end of the elastic member 33 abuts against the fixing part 342.

[0060] Referring to Figure 4, when the connecting part 5 is inserted into the fixing hole 21, in order to ensure the airtightness between the connecting part 5 and the fixing hole 21 and prevent gas leakage when the system generates negative pressure, the inner wall of the fixing hole 21 is provided with a second sealing groove 211, and a second sealing ring 22 is provided in the second sealing groove 211. After the connecting part 5 is inserted into the fixing hole 21, the inner wall of the second sealing ring 22 can abut against the outer wall of the connecting part 5, thereby achieving a good seal at the joint between the outer wall of the connecting part 5 and the fixing hole 21, preventing problems with the air pressure system.

[0061] In some embodiments, the fixing hole 21 further includes a connecting portion 212, the second sealing groove 211 is disposed on the inner wall of the connecting portion 212, and the inner wall of the connecting portion 212 is provided with a third inclined surface 23, the diameter of the third inclined surface 23 gradually decreasing along the first direction. The connecting portion 212 is used to accommodate the connecting portion 5 after engagement and insertion. The third inclined surface 23 facilitates the insertion of the connecting portion 5 into the fixing hole 21 from the connecting portion 212. Further, the outer edge of the connecting portion 212 is provided with a fourth inclined surface 24, the diameter of the fourth inclined surface 24 gradually decreasing along the first direction. By providing the fourth inclined surface 24, the connecting portion 5 is easily inserted into the connecting portion 212.

[0062] Referring to Figure 5, in some embodiments, the conductor seat 2 further includes an inner support portion 25, which protrudes from the inner wall of the fixing hole 21 to receive and fix the fixing valve body 34. The inner support portion 25 is provided with a limiting hole 251, and the fixing portion 342 is provided with a limiting protrusion 3421. The limiting protrusion 3421 can be inserted into the limiting hole 251 to limit and fix the fixing portion 342.

[0063] The inner support portion 25 is provided with a fixing ring 252, and the fixing valve core 31 is fixed inside the fixing ring 252. In this embodiment of the invention, the fixing valve core 31 is fixed inside the fixing ring 252 by fasteners such as screws. In other embodiments, the fixing valve core 31 can be indirectly fixed to the fixing ring 252 by other transition components.

[0064] Furthermore, the conductive seat 2 also includes an outer support portion 26, which is fixed to the seat body 1, thereby fixing the conductive seat 2 to the seat body 1.

[0065] Referring to Figure 7, an embodiment of the present invention also discloses a consumable box 200 for receiving waste and waste fluid from an operating table. The consumable box 200 is fixed in the consumable seat 100 as described above. The consumable box 200 includes a receiving cavity 6 and an insertion part 4. The receiving cavity 6 can communicate with a suction mechanism, which can suck waste or waste fluid into the receiving cavity 6. The insertion part 4 is provided with a connecting groove 41, and a communicating part 5 is provided in the connecting groove 41. The communicating part 5 protrudes from the connecting groove 41 to facilitate engagement with the guide seat 2. The communicating part 5 is provided with a connecting hole 51 for communicating with the receiving cavity 6. A second valve 7 is provided in the connecting hole 51, through which waste or waste fluid in the receiving cavity 6 can flow into the second valve 7. When the second valve 7 is open, waste or waste fluid can enter the first valve 3 through the second valve 7.

[0066] Referring to Figure 8, the inner wall of the engagement hole 51 is provided with a fixing protrusion 511, which protrudes from the inner wall of the engagement hole 51. The outer wall of the second valve 7 is provided with a limiting protrusion 71, which can abut against the fixing protrusion 511 to fix the second valve 7.

[0067] When the insertion part 4 is inserted into the seat 1 of the consumable box 200 from the first direction, the connecting part 5 can push the movable valve body 32 of the consumable box 200 to move in the first direction and make the connecting hole 51 connect with the connecting port 321 of the movable valve body 32. Then the system generates negative pressure, the second valve 7 opens, and waste or waste liquid can enter the first valve 3 through the second valve 7.

[0068] Referring to Figure 8, in some embodiments, the second valve 7 includes a connecting valve body 72 and a movable valve core 73. The connecting valve body 72 has a flow hole 721 communicating with the connecting hole 51. The flow hole 721 connects the connecting hole 51 to the receiving groove 3241, allowing waste or waste liquid to enter the receiving groove 3241. The movable valve core 73 controls the opening or closing of the flow hole 721. The movable valve core 73 includes a moving column 731 and a sealing piece 732 flexibly connected to the moving column 731. The sealing piece 732 is flexibly connected to the moving column 731 and can deform or bend to a certain extent relative to the moving column 731. The connecting valve body 72 also has a moving hole 722, through which the moving column 731 passes, and the moving hole 722 is used to fix the moving column 731. Simultaneously, the movable column 731 can move a certain distance within the movable hole 722 to accommodate the compression space generated when the second valve 7 engages with the receiving groove 3241. The sealing plate 732 extends from the movable column 731 away from its central axis and seals the connecting hole 3221. When the second valve 7 is closed, the sealing plate 732 forms a seal on the connecting hole 3221. When the system generates negative pressure, under the action of the pressure difference, the sealing plate 732 deforms or bends relative to the movable column 731, exposing the connecting hole 3221. At this time, the second valve 7 opens, and the connecting hole 3221 communicates with the receiving groove 3241.

[0069] When the insertion part 4 is inserted into the seat 1 from the first direction, the moving post 731 abuts against the sealing part 311 of the fixed valve core 31.
