Description

Technical Field

[0001] The present invention relates to the field of medical equipment, and in particular to a medical waste collection device. Background Art

[0002] During certain surgical procedures, liquid, semi-solid and solid wastes are inevitably generated, including body fluids such as blood and perfusion solutions introduced into the surgical site during surgery. Solid and semi-solid wastes generated during surgery include tissue fragments and small pieces of surgical materials that may remain in the body. Ideally, wastes should be collected as soon as they are generated so that they do not contaminate the surgical site or become biohazards in the operating room or other places where the surgical procedure is performed.

[0003] In the prior art, there are a variety of waste collection systems that can be used by medical staff to collect waste generated during surgery or after surgery. The principle is mainly to use a vacuum source to generate suction force to suck the waste 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, thereby sucking the waste into a specific collection container through the pipeline contacting the surgical site.

[0004] For example, the NEPTUNE medical waste collection device produced by Stryker in the prior art, see the attached Figure 1 , attached Figure 1 The figure is a schematic diagram of the structure of a medical waste collection device in the prior art, wherein the medical waste collection device 1 comprises a mobile unit 11, a vacuum source 12, a consumables box 14 and a waste collection tank 13. In the technical solution, since the pipeline 15 contacting the surgical site is connected to the waste collection tank 13 through a detachable consumables box 14, the mobile unit 11 can make the position of the medical waste collection device 1 more flexible during use.

[0005] but Figure 1In the shown and other solutions of the prior art, the vacuum source is directly connected to the waste collection tank, so as to generate negative pressure in the waste collection tank, and then the waste is sucked through the consumable box also connected to the waste collection tank and the pipeline connected to the consumable box. In this structure, since the waste collection tank is large in size and embedded in the mobile unit, the connection between the waste collection tank and the vacuum source is complicated, inconvenient to disassemble and maintain, and it is difficult to replace the vacuum source or the waste collection tank; and in order to prevent the liquid in the waste collection tank from entering the vacuum source, the connection structure between the vacuum source and the waste collection tank is made more complicated, and regular inspection and troubleshooting are required, and these manual operations are likely to be neglected, which will create the risk of equipment contamination. In addition, after the use of the medical waste collection equipment, the waste in the waste collection tank needs to be emptied and disinfected. At this stage, there is still a connecting pipeline between the waste collection tank and the vacuum source, and the transportation process and the emptying process will cause large-amplitude physical vibrations. Moreover, due to the existence of the mobile unit, the medical waste collection equipment filled with waste may get out of control during the transportation process. At this time, the physical connection between the waste collection tank and the vacuum source will still cause the waste in the waste collection tank to contaminate the equipment. Summary of the invention

[0006] The technical problem to be solved by the embodiments of the present invention is to provide a medical waste collection device, so that the vacuum source can be directly and conveniently connected to the consumable box, and at the same time, a suction force can be generated in the waste collection tank. There is no need to set a complex connection structure between the waste collection tank and the vacuum source, and the waste in the waste collection tank and the vacuum source can be effectively isolated, thereby reducing the risk of waste contamination of the equipment.

[0007] In order to solve the above technical problems, an embodiment of the present invention provides a medical waste collection device, including a waste collection tank for collecting waste and a mounting base for connecting the consumable box and the waste collection tank after installing a consumable box, wherein the mounting base includes:

[0008] A base plate, mounted on the medical waste collection device;

[0009] An access interface, mounted on the substrate and provided with a first access socket for inserting a first mounting connector of the consumable box and a second access socket for inserting a second mounting connector of the consumable box;

[0010] A first access portion, disposed behind the first access socket, for accessing a first mounting connector of the consumable box so that waste flows through the consumable box into the waste collection tank;

[0011] A second access portion, disposed behind the second access socket, for accessing a second mounting joint of the consumable box so that the vacuum source provides suction force to the waste collection tank through the consumable box;

[0012] A limit clamping plate, clamped on the first access portion and the second access portion to limit the positions of the first access portion and the second access portion;

[0013] The second access portion can move between the base plate and the limiting clamping plate to guide and correct the second mounting joint during the insertion of the second mounting joint.

[0014] Furthermore, the second connecting portion includes a first tube body and a second tube body, and an outer diameter of the first tube body is greater than an outer diameter of the second tube body.

[0015] Furthermore, the base plate is provided with an accommodating sleeve for accommodating the first tube body of the second access portion.

[0016] Furthermore, the limiting clamping plate is provided with a second limiting clamping hole for connecting to the second tube body of the second connecting portion, and the second limiting clamping hole and the second tube body are clearance-fitted.

[0017] Furthermore, the outer diameter of the first tube body is greater than the diameter of the second limiting hole.

[0018] Furthermore, the second connecting portion further includes a third tube body, the third tube body is connected to the second tube body and the other end of the third tube body is connected to the vacuum source, and the inner diameter of the third tube body is smaller than the inner diameter of the second tube body.

[0019] Furthermore, the first tube body includes a first guide inlet for guiding the second mounting joint during the insertion process of the consumable box, and the first guide inlet is truncated cone-shaped.

[0020] Furthermore, the second access socket includes two second guide entrances for guiding the second mounting connector during the insertion process of the consumable box, and the first guide entrance is truncated cone-shaped.

[0021] Furthermore, a sealing ring is provided in the first tube body.

[0022] Furthermore, the sealing ring is arranged in a sealing groove in the inner cavity of the first tube body.

[0023] The implementation of the embodiments of the present invention has the following beneficial effects:

[0024] First, in the embodiment of the present invention, the mounting base is connected to the second mounting joint added to the consumable box for connecting the vacuum source, so that the vacuum source does not need to be directly connected to the waste collection tank, thereby avoiding the need to set a complex connection structure between the waste collection tank and the vacuum source, making the vacuum source and the waste collection tank easy to disassemble and maintain;

[0025] Secondly, after placing the consumables box, the waste collection tank and the vacuum source are also effectively isolated by the consumables box, thereby reducing the risk of waste contaminating the equipment. Moreover, the consumables box is a disposable component, so that no matter whether it is in use or not, the waste in the waste collection tank is difficult to directly contact the vacuum source, thereby effectively reducing the risk of waste contaminating the equipment;

[0026] At the same time, the second access portion can guide and correct the second mounting joint during the insertion process through a rocking structure, so that the second mounting joint can be stably and smoothly connected to the mounting base even if it is not aligned, without the need to pull it out and re-align it, which is convenient for the operator to install the consumable box conveniently and quickly, and makes the insertion of the second mounting joint of the consumable box more stable and smooth, and will not cause damage to the corresponding socket of the mounting base due to improper force of the operator.

[0041] The housing 1001 includes a first consumable box inner cavity 1020 and a second consumable box inner cavity 1030 which are isolated from each other; preferably, the first consumable box inner cavity 1020 and the second consumable box inner cavity 1030 are isolated from each other by a partition wall. In some cases, the first consumable box inner cavity 1020 and the second consumable box inner cavity 1030 may not be completely isolated from each other;

[0042] The first mounting joint 1300 is located on the housing 1001 and communicates with the inner cavity 1020 of the first consumable box, and is used to connect with the medical waste collection device 2000 to allow the waste to enter the waste collection tank 2100 .

[0043] The second mounting connector 1100 is disposed on the housing 1001 and communicates with the second consumable box inner cavity 1030, and is used to connect to the mounting base 3000 of the medical waste collection device 2000 to simultaneously connect the medical waste collection device 2000 and the second consumable box inner cavity 1030. Figure 5 The vacuum source 2200 and the waste collection tank 2100 of the medical waste collection device are shown;

[0044] The connecting base 1200 is assembled on the housing 1001 and communicates with the inner cavity 1030 of the second consumable box, and is used to connect the external suction line 2500. Specifically, the connecting base 1200 is provided with an introduction interface 1201; see Figure 5 As shown, Figure 5 The medical waste collection device 2000 includes a vacuum source 2200 , but in other embodiments, the vacuum source 2200 may not be included in the medical waste collection device 2000 , but may be used as an independent device;

[0045] The connection base 1200 also includes a first pipe cap (not shown in the figure) which is the same in number as the introduction joint 1201 and can be matched with the introduction joint 1111; the shell 1001 can also be provided with corresponding pipe caps that are matched with the second installation joint 1100 and the first installation joint 1300.

[0046] like Figure 4 as well as Figure 7-10 As shown, an embodiment of the present invention provides a mounting base 3000, and the mounting base 3000 includes:

[0047] The substrate 3100 is installed on the medical waste collection device 2000; the substrate 3100 is preferably made of stainless steel or engineering plastics;

[0048] The access interface 3200 is mounted on the substrate 3100 and is provided with a first access socket 3210 for inserting the first mounting joint 1300 of the consumable box 1000 and a second access socket 3210 for inserting the second mounting joint 1100 of the consumable box 1000; the surface shape of the access interface 3200 may be the same as the surface shape of the consumable box 1000 in contact with the consumable box after insertion, and the access interface 3200 may be a separate component assembled on the substrate 3100, or may be integrally formed with the substrate 3100;

[0049] The first access portion 3400 is disposed behind the first access socket 3210 and is used to access the first mounting connector 1300 of the consumable box 1000 so that waste flows into the waste collection tank 2100 through the consumable box 1000;

[0050] The second access portion 3500 is disposed behind the second access socket 3210 and is used to connect to the second mounting connector 1100 of the consumable box 1000 so that the vacuum source provides suction force to the waste collection tank 2100 through the consumable box 1000;

[0051] The limiting card plate 3300 is clamped on the first access portion 3400 and the second access portion 3500 to limit the positions of the first access portion 3400 and the second access portion 3500; the limiting card plate 3300 is preferably made of stainless steel or engineering plastics;

[0052] The second access portion 3500 can move between the base plate 3100 and the limiting clamping plate 3300 to guide and correct the second installation joint 1100 during the insertion process of the second installation joint 1100 .

[0053] Specific as Figure 4 and Figure 5 As shown, the consumable box 1000 is connected to, preferably, plugged into, a medical waste collection device 2000. The medical waste collection device 2000 includes a waste collection tank 2100, a vacuum source 2200 and a mobile unit 2300. The second mounting joint 1100 is connected to the vacuum source 2200 through the vacuum source pipeline 2400 inside the medical waste collection device 2000. The second mounting joint 1100 is also connected to the waste collection tank 2100 gas circuit, and enables the vacuum source 2200 to suck the waste collection tank 2100 to form a suction force in the suction waste collection tank 2100. The liquid circuit connection part 1100 is connected to the storage connection part 1200, and the storage connection part 1200 is connected to the waste collection tank 2100. Preferably, the first mounting joint 1300 further includes an air passage 1301 connected to the waste collection tank 2100, and the air passage 1301 is connected to the second mounting joint 1100 through the in-box air passage 1302, so that the vacuum source 2200 forms a suction force in the waste collection tank 2100 through the second mounting joint 1100 of the consumable box 1000. In this embodiment, the first consumable box inner cavity 1020 and the second consumable box inner cavity 1030 do not need to be completely isolated, but form an in-box air passage 1302, and the air passage 1301 is reused with the liquid passage of the first mounting joint 1300, and a barrier structure is provided between the air passage 1301 and the liquid passage to prevent the liquid passage from entering the air passage.

[0054] See also Figure 8-Figure 10As shown, the second access portion 3500 includes a first tube body 3510 and a second tube body 3520, wherein the outer diameter of the first tube body 3510 is greater than the outer diameter of the second tube body 3520. The base plate 3100 is provided with a receiving sleeve 3110 for accommodating the first tube body 3510 of the second access portion 3500, and there is a clearance fit between the receiving sleeve 3110 and the first tube body 3510, that is, there is a certain gap between the inner wall of the receiving sleeve 3110 and the outer wall of the first tube body 3510, so that the first tube body 3510 can shake in the receiving sleeve 3110. Further, the limiting clamping plate 3300 is provided with a second limiting clamping hole 3320 for accessing the second tube body 3520 of the second access portion 3500, and there is a clearance fit between the second limiting clamping hole 3320 and the second tube body 3520, so that the second tube body 3520 can shake in the receiving sleeve 3320.

[0055] The first tube body 3510 also includes a first guide inlet 3540 for guiding the second mounting connector 1100 during the insertion process of the consumable box 1000, see Fig. 9 and Fig.10 The first guide inlet 3400 is in the shape of a truncated cone. The guide inlet 3540 allows the second mounting joint 1100 to have a gap and a tolerance space when being inserted into the first tube body 3510, so that the two will not collide with each other, and as the inner diameter of the first tube body 3510 gradually decreases, the position of the second mounting joint 1100 will gradually align. Further, since there is a gap between the inner wall of the accommodating sleeve 3110 and the outer wall of the first tube body 3510 that allows the first tube body 3510 to shake in the accommodating sleeve 3110, and there is a clearance fit between the second limiting clamp hole 3320 and the second tube body 3520, even if the second mounting joint 1100 is not completely aligned with the second access portion 3500 during the insertion process, there will be no collision due to force during the insertion process, and the insertion process will not be terminated. Instead, the position is further aligned through the small swing of the second access portion 3500 between the base plate 3100 and the limiting clamp plate 3300.

[0056] Furthermore, since the outer diameter of the first tube body 3510 is larger than the diameter of the second position-limiting hole 3320, the second position-limiting hole 3320 can limit the position of the second access portion 3500 after the second mounting joint 1100 is finally inserted. Preferably, the second access portion 3500 further includes a third tube body 3530, which is connected to the second tube body 3520 and the other end of which is connected to the vacuum source 2200, and in order to provide a higher pressure value, the inner diameter of the third tube body 3530 is smaller than the inner diameter of the second tube body 3520. The outer diameter of the third tube body 3530 is also smaller than the outer diameter of the second tube body 3520 to facilitate connection with the internal pipeline.

[0057] In order to better align, the second access socket 3220 also includes a second guide entrance 3221 for guiding the second mounting joint 1100 during the insertion process of the consumable box 1000, and the second guide entrance 3221 is truncated cone-shaped. Furthermore, the second mounting joint 1100 of the consumable box 1000 is also improved accordingly, and the shape of the second mounting joint 1100 is also made into a truncated cone, and the outer diameter of its open end 1111 is smaller than the outer diameter of its joint end 1112, so that it can reduce the collision with the inner cavity of the second access part 3500 after entering the second access part 3500.

[0058] See also Fig. 9 and Fig.10 In order to ensure the suction force, a sealing ring 3560 is provided in the first tube body 3510 , and the sealing ring 3560 is arranged in the sealing groove 3550 of the inner cavity of the first tube body 3510 .

[0059] The implementation of the embodiments of the present invention has the following beneficial effects:

[0060] First, in the embodiment of the present invention, the mounting base is connected to the second mounting joint added to the consumable box for connecting the vacuum source, so that the vacuum source does not need to be directly connected to the waste collection tank, thereby avoiding the need to set a complex connection structure between the waste collection tank and the vacuum source, making the vacuum source and the waste collection tank easy to disassemble and maintain;

[0061] Secondly, after placing the consumables box, the waste collection tank and the vacuum source are also effectively isolated by the consumables box, thereby reducing the risk of waste contaminating the equipment. Moreover, the consumables box is a disposable component, so that no matter whether it is in use or not, the waste in the waste collection tank is difficult to directly contact the vacuum source, thereby effectively reducing the risk of waste contaminating the equipment;

[0062] At the same time, the second access portion can guide and correct the second mounting joint during the insertion process through a rocking structure, so that the second mounting joint can be stably and smoothly connected to the mounting base even if it is not aligned, without the need to pull it out and re-align it, which is convenient for the operator to install the consumable box conveniently and quickly, and makes the insertion of the second mounting joint of the consumable box more stable and smooth, and will not cause damage to the corresponding socket of the mounting base due to improper force of the operator.

[0063] The above disclosure is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
