Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical apparatus and instruments, and particularly relates to a device for perfusion test of intestinal fluid before temporary stoma is returned. BACKGROUND

[0002] For the surgery of resection and anastomosis of the colon for rectal cancer, in order to avoid the difficulty in healing of the rectal anastomotic stoma caused by feces, a temporary stoma method is often used, that is, the terminal segment of the small intestine is temporarily placed outside the skin of the right lower abdomen, and two openings are formed after the small intestine is opened: one opening flows out the small intestinal fluid, and the small intestinal fluid flows into the stoma bag without forming feces; the other opening leads to the colon and anus. After 3 months of rectal cancer surgery, the temporary stoma of the small intestine is operated to return the temporary stoma into the abdominal cavity. However, there are several difficulties in the operation of returning the temporary stoma:

[0003] 1. Whether the rectal anastomotic stoma is completely healed, if not, the return of the temporary stoma will lead to difficulty in healing of the anastomotic stoma and cause pelvic or perianal infection;

[0004] 2. For low rectal anastomosis, whether the anal function is restored to a satisfactory degree, if the anal function is still poor, the patient will suffer a lot after the return;

[0005] 3. The entire colon has not received intestinal fluid for more than 3 months, whether the colon function is good, some patients may have acute enteritis and other complications after the return.

[0006] The above difficulties after the return of the temporary stoma can be solved by perfusing the small intestinal fluid into the distal intestinal tube of the temporary stoma before the return. The small intestinal fluid is perfused into the distal intestinal tube of the stoma, and feces is formed in the colon, which can test the anastomotic stoma and anal function, and help the recovery of the colon function. If the anastomotic stoma or anal function is found to be poor, the perfusion can be stopped to continue the treatment of the anastomotic stoma and anal function, thereby avoiding the failed return operation. However, due to the narrowness and bending of the distal intestinal tube of the temporary stoma, it is difficult to directly inject the small intestinal fluid into it. So far, there is no device for perfusing the small intestinal fluid into the distal small intestine. CONTENT OF THE UTILITY MODEL

[0035] In order to further illustrate the technical means and effects adopted by the present application to achieve the predetermined purpose of the present application, the specific implementation, structure, features and effects of the vehicle pre-warning system of the intercommunication overpass entrance according to the present application will be described in detail as follows in combination with the drawings and the preferred embodiments.

[0036] As Figures 1-4As shown, the temporary stoma for the anterior intestinal fluid infusion test device in this embodiment, including the bottom hollow shell 1, the infusion assembly 2 and the water pump assembly 3 covered in the shell 1 inside; The device adopts integrated design, cleverly integrates the infusion assembly 2 and the water pump assembly 3 in the shell 1, so that the whole device structure is compact, light and convenient for medical staff to operate.

[0037] The infusion assembly 2 is inserted into the distal end of the stoma, and the other end is connected with the water outlet 34 of the water pump assembly 3; It not only ensures the accuracy of infusion, but also improves the reliability of the device;

[0038] The shell 1 is semicircular, and the bottom is movably connected with the bottom disc of the two-piece stoma bag. The bottom of the shell 1 is movably connected with the bottom disc of the two-piece stoma bag, which ensures stability and does not loosen.

[0039] In specific use, the rubber tube has been pre-fixed in the clamping groove 11 on the inside of the shell 1, connected with the water outlet 34 of the peristaltic pump 31, and reserved about 5 cm length to extend into the distal intestinal tube of the stoma, which is universally applicable. First, the hollow ball-shaped head end 22 of the infusion assembly 2 is pinched and inserted into the distal end of the stoma, and after insertion, the pinched ball shape pops up, which can support in the intestinal tube to prevent falling out. Then push the rubber tube into the small intestine cavity appropriately, without requiring too much. Then connect the plastic shell to the two-piece stoma bag bottom disc. When the temporary stoma flows out of the small intestine fluid and covers the water pump assembly 3, the power supply can be connected, and the water pump assembly 3 will infuse the small intestine fluid into the distal intestinal tube through the rubber tube; There may be part of the small intestine fluid reflux, but it is still in the plastic shell, and the infusion can continue, which does not affect the use.

[0040] During the infusion process, medical staff can closely observe the patient's reaction and the emptying of the intestinal tract to evaluate the healing of the rectal anastomosis, the recovery degree of the anal function and the adaptability of the colon function. If abnormal conditions are found, the infusion can be stopped immediately and appropriate measures can be taken.

[0041] The utility model relates to a device for infusing small intestinal fluid into the distal intestinal tube of temporary stoma, aiming at simulating the physiological process that small intestinal fluid flows into the colon naturally after being returned and forms feces.

[0042] Further, please refer to Figure 2 and Figure 4 The shell 1 includes a semicircular cavity 12 and a storage cavity 13 at the bottom end; The storage cavity 13 serves as a temporary collection area for intestinal fluid reflux or waste liquid, improving the functionality and practicality of the device. The semicircular cavity 12 of the shell 1 not only conforms to the ergonomic principle, can closely fit the abdominal contour of the patient, reduces the sense of oppression and discomfort; Also provides enough internal space to accommodate key components such as the infusion assembly 2 and the water pump assembly 3, ensuring the overall performance and stability of the device.

[0043] The water pump assembly 3 comprises a peristaltic pump 31 and a low-speed motor 32; the peristaltic pump 31 is provided with a water inlet 33 and a water outlet 34 at two ends respectively; one end of the perfusion assembly 2 is connected with the water outlet 34; the water inlet 33 is used for perfusing the small intestinal fluid into the rubber tube and into the distal intestinal tube;

[0044] The low-speed motor 32 is arranged in the sealed cavity 15 on one side of the storage cavity 13, and the power line of the low-speed motor 32 is electrically connected with the power socket 4 arranged at the top end of the outer shell 1 along the guide groove in the inner wall of the outer shell 1.

[0045] In this embodiment, the motor and the pump body are separated, the peristaltic pump 31 and the low-speed motor 32 are preferably INTLLAB pump head + 12V DC motor 80-220mL / min model; the integration of the peristaltic pump 31 and the low-speed motor 32 not only meets the stable power output required by the intestinal fluid perfusion, but also improves the accuracy and reliability of the test through fine flow control. The application requires that the small intestinal fluid in the stoma bag can be pushed into the distal intestinal tube through the perfusion tube. Since the small intestinal fluid may be viscous or even semi-dry feces, a large pushing force is required, the tube cannot be blocked, and the injection speed is slow; therefore, the above peristaltic pump 31 and low-speed motor 32 can meet the requirements of perfusion.

[0046] At the same time, the low-speed motor 32 is separated and arranged in the sealed cavity 15, avoiding the impact of liquid on it, and the motor is isolated from the liquid environment, reducing the motor failure caused by factors such as moisture and corrosion, thereby prolonging the service life of the motor and reducing the maintenance cost of the overall equipment.

[0047] The power line of the low-speed motor 32 is electrically connected with the power socket 4 arranged at the top end of the outer shell 1 along the guide groove in the inner wall of the outer shell 1. In order to facilitate the start and stop of the low-speed motor 32, a power switch 5 is arranged beside the power socket 4 at the top end of the outer shell 1, which provides the user with the function of directly controlling the power on and off, increasing the safety and convenience of the equipment. The power switch 5 allows the user to directly control the power on and off of the low-speed motor 32 without the need for other complex operations or disassembly of the outer shell 1. In this way, when the user needs to pause or complete the use, the power can be quickly cut off to avoid unnecessary operation of the equipment or energy waste. The power switch 5 should be designed in a style that is easy to identify and operate, such as a button type or a dial type, to ensure that the user can quickly and accurately control the power on and off.

[0048] The power line passes through the guide groove to the inside of the upper end of the plastic shell and is connected with a power socket 4. The power socket 4 is fixed on the outside of the plastic shell, which is convenient for users or medical staff to operate and connect the external power supply.

[0049] The type of power socket 4: the power socket 4 adopts the commonly used low-voltage direct-current male and female power socket 4 on the market, and generally is the female end. This standardized design enables users to easily find matching power lines for connection without worrying about compatibility issues. At the same time, the use of low-voltage direct-current power also ensures the safety of the device during use.

[0050] Further, a plurality of card slots 11 are fixedly arranged on the inner wall of the outer shell 1, and the perfusion assembly 2 is clamped in the card slot 11.

[0051] The design of the card slot 11 ensures the vertical guidance of the rubber tube. By precisely controlling the inclination angle and depth of the card slot 11, it is ensured that the rubber tube can be vertically extended to the stoma. This vertical guidance design not only helps to reduce resistance and pressure loss during perfusion, but also improves the accuracy and efficiency of perfusion.

[0052] As a preferred embodiment, considering that it is appropriate for the plum blossom-shaped head end 22 to extend about 5 cm into the distal stoma in most cases, the rubber tube can be connected to the water outlet 34 of the peristaltic pump 31 before the product is shipped, and fixed in the card slot 11, with a length of 5 cm reserved for extending into the distal stoma. In this way, only two actions are required during installation: 1. pinch the head end 22 of the rubber tube and insert it into the distal stoma; 2. fix the outer shell 1 on the bottom plate of the two-piece stoma bag.

[0053] Before the product is shipped, the rubber tube and the water outlet 34 of the peristaltic pump 31 have been pre-connected and fixed firmly in the card slot 11. In addition, the rubber tube also has an extra length of 5 cm reserved for extending into the distal stoma. This pre-assembly design not only simplifies the installation steps, but also avoids errors and leakage problems that may occur during on-site connection.

[0054] Please refer to Figure 3 In this application, the perfusion assembly 2 includes a perfusion tube 21 and a plum blossom-shaped head end 22 arranged at the front end; a plurality of openings 23 are arranged on the head end 22; the above design combines the advantages of linear perfusion and multi-point distributed perfusion, enabling the intestinal fluid to be more evenly distributed in the intestinal tract, improving the accuracy and effectiveness of the test; a plurality of openings 23 are arranged on the head end 22, which allow the intestinal fluid to be sprayed in finer streams, further enhancing the uniformity and coverage area of perfusion.

[0055] The perfusion tube 21 and the head end 22 are both made of rubber material; rubber material has good flexibility and biocompatibility, which can adapt to different shapes and sizes of stoma, reducing the discomfort of patients

[0056] The head end 22 is hollow and flat spherical type and its outer diameter is larger than the perfusion tube 21. The outer diameter of the head end 22 is larger than the perfusion tube 21, so that the head end 22 can be more closely attached to the inner wall of the intestinal tract, improving the efficiency and accuracy of perfusion.

[0057] As a preferred embodiment, the outer diameter of the perfusion tube 21 is 8mm, the inner diameter is 6mm, and the length is 15-20cm.

[0058] The outer diameter of the perfusion tube 21 is set to 8mm, and the inner diameter is 6mm. The size of the preferred embodiment ensures the sufficiency of the perfusion flow, and avoids the discomfort caused by the large outer diameter to the patient. The length of the perfusion tube 21 is in the range of 15-20cm, which can be adjusted according to the specific situation of the patient to adapt to the stoma of different depth and position.

[0059] Further, the end of the outer shell 1 connected with the bottom plate of the stoma bag is respectively provided with a corresponding buckle 14. The buckle 14 generally includes male and female two parts, which are respectively installed on the outer shell 1 and the bottom plate. Through the simple buckling action, the stable connection between the outer shell 1 and the bottom plate can be realized.

[0060] The application focuses on providing a way to perfuse small intestinal fluid to the distal intestinal tube of temporary stoma, simulating the physiological condition that the small intestinal fluid flows into the colon after being returned, and forming feces in the colon. It does not exclude other ways, including changing the size, shape and material of the rubber tube, and changing the injection mode of the peristaltic pump 31, to complete the purpose of perfusing small intestinal fluid to the distal intestinal tube.

[0061] The embodiments are further described in combination with the application, but the application is not limited to the above embodiments. Within the knowledge range of ordinary skilled in the art, various changes can be made without departing from the purpose of the application.
