Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a kidney protection bag used in kidney transplantation surgery. Background Technology

[0002] Existing technologies for organ preservation during kidney surgery, such as the ice chip method, hard box packaging, and commercially available medical insulated bags, all have different drawbacks. For example, the ice chip method is prone to causing ice chips to stick and damage the organ surface, and the temperature fluctuations during preservation can be large due to the contact between ice chips and the organ and the influence of the surrounding environment, which can have a certain impact. Commercially available insulated bags are thicker than 15mm, have poor temperature uniformity (±3°C), and lack a visualization window. This can lead to problems such as the kidney entering thermal ischemia and microthrombus formation when the vascular clamps age and fail, which cannot be detected in time. At the same time, when storing the kidney, existing sealing devices can only control the temperature of the bottom and sides of the kidney when maintaining low or constant temperature, and cannot control the temperature of the top of the kidney. Utility Model Content

[0003] The purpose of this invention is to provide a kidney protection bag for use in kidney transplantation surgery, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a kidney protection bag for use in kidney transplantation surgery, comprising a kidney bag and an ice bucket connected to the kidney bag;

[0005] The kidney bag includes an inner liner and an outer liner, with a water cavity formed between the inner liner and the outer liner;

[0006] The inner wall of the outer liner is provided with a number of interconnected air bladder strips. A sealing bag is provided above one side of the kidney bag, and a self-adhesive tape is provided on the inner side of the sealing bag. A second self-adhesive tape is provided on the side of the outer liner away from the sealing bag.

[0007] As a further improvement of this utility model: the inner lining layer is made of transparent, non-toxic polyvinyl chloride, and the outer lining layer is made of transparent medical-grade polypropylene.

[0008] As a further improvement of this utility model, the thickness of both the inner lining layer and the outer lining layer is ≤5mm.

[0009] As a further improvement of this utility model: the water cavity is connected to the external ice bucket via a connecting hose.

[0010] As a further embodiment of this utility model: the airbag strips are vertically arranged from top to bottom on the inner wall of the outer liner, and several airbag strips are connected by flexible connecting air bags. An inflation port for inflating the airbag strips is provided above the kidney bag.

[0011] As a further improvement of this utility model: a handle is provided on the upper side of one side of the kidney bag, and a kidney pedicle opening is provided on the lower side of one side of the kidney bag.

[0012] As a further improvement of this utility model: a drain pipe with a water controller is connected to the side of the kidney bag away from the connecting hose.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model provides a kidney protection bag for use in kidney transplantation surgery. It uses a double-layer transparent material to allow real-time observation of the kidney. The water chamber is connected to an ice water container through a disposable medical rubber tube, and the ice bucket is placed externally, which reduces the volume of the kidney protection bag in the body cavity. Moreover, ice water is circulated after being placed in the body, which reduces the size of the incision for the robot to insert the kidney. At the same time, the sealing part adopts multi-layer folds, which not only improves the sealing effect, but also ensures that the upper part of the kidney can also be contacted for temperature control.

[0015] 2. This utility model inflates the airbag strips through the inflation port and uses connecting air bags to inflate several airbag strips, ensuring that the water cavity formed between the inner and outer lining layers is supported, making it easy to flush the water cavity. In contrast, if several interconnected airbag strips are not provided, the inner and outer lining layers will stick together, making it inconvenient to use an ice bucket for flushing and temperature control.

[0016] 3. The advantage of setting the airbag strip on the inner wall of the outer liner is that it can expand and support the water cavity after the airbag strip is inflated, while forming a certain distance from the human organs, reducing the contact area between the water cavity and the inner wall of the human body, preventing low temperature stimulation to surrounding organs and tissues, and reducing the incidence of postoperative intestinal obstruction.

[0023] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0024] Given the shortcomings of existing methods such as ice chip preservation, hard-pack packaging, and medical insulated bags, many hospitals have made corresponding improvements to the protective bags for preserving kidney organs with the development of modern medical technology. Relevant patent documents exist in the current State Intellectual Property Office, such as CN205848496U, which discloses a cryopreservation bag for donor kidneys used in kidney transplantation, and CN204560762U, which discloses a preservation bag used in kidney transplantation. Other examples include CN... 215381041U also discloses a series of improvements to the current original preservation methods, such as a cryopreservation bag for transplanted kidneys used in laparoscopy. However, these improvements are not very effective in preserving kidneys. The reasons are as follows: Firstly, even if these preservation bags (boxes) form an intermediate layer for chamber heat exchange, once inside the abdominal cavity, the intermediate layer is partially compressed due to the pressure from other organs in the abdominal cavity, preventing the heat exchange ice water (hot water) from covering the kidney. This results in some areas of the kidney not being able to fully contact the temperature from the intermediate layer to complete heat exchange. Secondly, because the kidney is placed in a bag (box), many preservation bags are mass-produced, resulting in the upper part of the entire protective bag not being treated. After entering the abdominal cavity, some parts of the kidney will not fully contact the heat exchange (cold) of the intermediate layer, which is not conducive to the recovery of the kidney's physiological function. This is why even with protective bags (boxes), the entire periphery of the kidney cannot be completely covered for heat exchange.

[0025] This technical solution can effectively improve these defects. The detailed structure of this technical solution is as follows:

[0026] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4As another embodiment of this utility model: it includes a kidney bag 1 and an ice bucket 2 connected to the kidney bag 1; the kidney bag 1 includes an inner liner 3 and an outer liner 4, the inner liner 3 is made of transparent non-toxic polyvinyl chloride layer, and the outer liner 4 is made of transparent medical polypropylene layer, the thickness of the inner liner 3 and the outer liner 4 is ≤5mm; a water cavity 5 is formed between the inner liner 3 and the outer liner 4; the water cavity 5 is connected to the external ice bucket 2 through a connecting hose 10, and water is flushed into the water cavity 5 by using the ice bucket 2 and the connecting hose 10, thereby achieving temperature control of the internal kidney, and after the kidney pedicle is anastomosed, the ice bucket device can be replaced with warm water for rapid rewarming.

[0027] The inner wall of the outer liner 4 is provided with several interconnected airbag strips 6. The airbag strips 6 are vertically arranged from top to bottom on the inner wall of the outer liner 4. The airbag strips 6 are connected by flexible connecting air bags 15. An inflation port for inflating the airbag strips 6 is provided above the kidney bag 1. The airbag strips 6 are inflated through the inflation port. The connecting air bags 15 are used to inflate all the airbag strips 6, ensuring that the water cavity 5 formed between the inner liner 3 and the outer liner 4 can be supported, which is convenient for flushing the water cavity 5. In comparison, if several interconnected airbag strips 6 are not provided, the inner liner 3 and the outer liner 4 will stick together, which is not convenient for flushing and temperature control through the ice bucket 2.

[0028] like Figure 3 As shown, a sealing bag 7 is located on the upper side of one side of the kidney bag 1. A self-adhesive tape 8 is located inside the sealing bag 7. A second self-adhesive tape 9 is located on the side of the outer liner 4 away from the sealing bag 7. When sealing and storing the kidney, first fold the side away from the sealing bag 7 inwards to ensure contact with the upper part of the kidney inside the kidney bag 1. The ice is then adhered to the inner wall of the kidney bag 1 using the second self-adhesive tape 9. Then, the sealing bag 7 is also folded inwards to ensure that the inner self-adhesive tape adheres to the outer side of the kidney bag 1. This not only improves the sealing effect but also ensures that the upper part of the kidney can also be contacted for temperature control, thus achieving comprehensive temperature control of the kidney. Please refer to the specific diagram for details. Figure 3 .

[0029] As a further improvement of this utility model: a gripper 11 is provided on the upper side of one side of the kidney bag 1, and a kidney pedicle opening 12 is provided on the lower side of one side of the kidney bag 1. The gripper 11 is left on the upper front of the kidney bag, which facilitates the robot to adjust the position of the donor kidney. After the donor kidney is anastomosed and rewarmed, it is easy to quickly cut the donor kidney bag from this point.

[0030] Other embodiments of this utility model: A drain pipe 13 is connected to the side of the kidney bag 1 away from the connecting hose 10, and a water controller 14 is provided on it. The water controller 14 is used to control the flow rate of the drain pipe 13 when draining.

[0031] In another embodiment of this utility model: a cryoprotective layer 16 is arranged on one side of the outer liner 4. This cryoprotective layer 16 can be a medical-grade liner. Its purpose is to protect the side facing the abdominal wall from the low temperature in the water cavity 5 after the entire kidney bag 1 is placed into the abdominal cavity, thus preventing low-temperature damage to the body and avoiding low-temperature stimulation to surrounding organs and tissues, and reducing the incidence of postoperative intestinal obstruction. This embodiment only provides the installation position on one side. In existing surgeries, the cryoprotective layer 16 can actually be placed all over the outer liner 4, which would be more effective.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
