Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a special retention enema device for hepatic encephalopathy. Background Art

[0002] Hepatic encephalopathy, also known as hepatic coma, is a complex symptom of central nervous system dysfunction caused by severe liver disease and based on metabolic disorders. There are many causes, including gastrointestinal bleeding and constipation. The following measures can be taken to clear intestinal blood accumulation: oral or nasogastric administration of lactulose, lactose sorbitol solution or 25% magnesium sulfate, enema with saline or weak acid (such as acetic acid), and enema with lactulose diluted to 33.3%. Studies have shown that there is a significant correlation between the activity of colonic flora and the development of hepatic encephalopathy. In clinical nursing work, retention enema is often used to maintain the acidic environment in the patient's intestines and reduce ammonia absorption to improve the patient's prognosis.

[0003] At present, there are three main ways of clinical nursing enema. The first is to use a disposable enema bag. In this way, the flow rate of the drug solution is too fast and difficult to control, resulting in poor treatment effect. In addition, the diameter of the disposable enema bag tube is relatively thick and hard. After inserting it into the anus, the patient has obvious urge to defecate and discomfort. In addition, the injection of the drug solution further stimulates intestinal peristalsis, causing the drug solution to flow out rapidly. Therefore, it is often difficult to achieve true retention enema; the second is to use a disposable infusion set in combination with a latex tube. The amount of drug solution used in hepatic encephalopathy enema is mostly 100mL. The combination of a disposable infusion set and a latex tube will cause about 12 to 15mL of drug solution to remain inside the tube, resulting in a certain degree of drug solution waste; the third is to use a 50mL syringe in combination with a suction tube, but this method is not easy to control the injection pressure, and the drug solution cannot fully exert its effectiveness.

[0004] Retention enema devices have appeared in the existing technical solutions, such as the sleeve device with authorization announcement number CN201147525Y for colon retention enema, in which an air bag is inserted into the front end and the rear end of the liquid infusion catheter. When performing colon enema, the two air bags need to be inflated, the front air bag is to block the passage to the small intestine, and the rear air bag is to block the anus. However, when using this device, the two air bags need to be inflated at the same time, resulting in extremely poor comfort.

[0005] For example, a retention enema device with the authorization announcement number CN 218501070 U has a fixed air bag on the enema liquid catheter, a connecting tube on the fixed air bag, an outer wall of the connecting tube with an external thread, an inflation component threadedly connected to the connecting tube, the fixed air bag is inflated by the inflation component, the fixed air bag expands, and the fixed air bag is closely fitted to the patient's anus. However, in this device, the inflation component is directly connected to the fixed air bag through the connecting tube, and air leakage accidents are prone to occur in the connecting part, making the device unable to function. Summary of the invention

[0006] The purpose of the utility model is to overcome the deficiencies of the prior art and to propose a special retention enema device for hepatic encephalopathy, which can fix the position of the enema device during the enema process to prevent leakage from the patient's anus, and at the same time is simple to operate, improves the patient's comfort, avoids air leakage accidents, and ensures the accuracy of the enema process.

[0007] In order to achieve the above objectives, the utility model proposes the following technical solutions:

[0008] The invention relates to a retention enema device specially used for hepatic encephalopathy, comprising an injection tube and an air bag assembly, wherein the air bag assembly comprises a balloon, a ventilation sleeve, an inflation tube and an inflatable balloon, wherein the balloon is an annular balloon body, wherein the balloon comprises an outer ring wall and an inner ring wall, wherein the inner ring wall has low elasticity and the outer ring wall has high elasticity; an injection channel is arranged in the ventilation sleeve, one side of the inner ring wall is opened, the injection channel is connected with the opening of the inner ring wall, and the balloon and the ventilation sleeve are sleeved on the injection tube; the inflatable balloon is connected with the injection channel through the inflation tube, an air release valve and a one-way air valve are arranged on the inflation tube, the one-way air valve is arranged between the inflatable balloon and the air release valve, the one-way air valve only allows gas to flow from the inflatable balloon to the balloon, and an air inlet valve is arranged on the inflatable balloon, during the process of inflating the balloon, the outer ring wall of the balloon expands outwardly along the diameter direction and becomes larger, and the deformation of the inner ring wall will not affect the circulation of liquid in the injection tube.

[0009] One end of the injection tube is provided with an enema liquid inlet, a branch tube is provided on the injection tube, a drug injection port is provided on the branch tube, and the other end of the injection tube is a hose to reduce the patient's discomfort when inserted into the anus. An injection valve is provided at the enema liquid inlet, and an injection valve is provided at the drug injection port.

[0010] The above-mentioned balloon, ventilation sleeve, inflatable airbag, deflation valve and one-way air valve are already in the prior art and can be directly used by those skilled in the art.

[0011] Preferably, the enema liquid inlet cooperates with an infuser to perform infusing of the liquid, such as lactulose, for treating hepatic encephalopathy. The infuser can be a syringe or other device capable of injecting the drug.

[0012] Preferably, the injection port is used in conjunction with a syringe to inject medicine, such as enema, antibiotics, etc.

[0013] Preferably, a circle of annular openings is opened on the side of the inner ring wall of the balloon, and the gas injection channel is an annular channel, so that the inflation speed is accelerated, the efficiency is improved, and the operation is convenient.

[0014] Preferably, the injection tube is coaxially arranged with the ventilation sleeve.

[0015] Preferably, the injection tube is provided with a first limiting ring and a second limiting ring, and the balloon and the ventilation sleeve are placed between the first limiting ring and the second limiting ring. The first limiting ring and the second limiting ring limit the positions of the balloon and the ventilation sleeve to further ensure the accuracy of the operation.

[0016] Preferably, the first limiting ring and the second limiting ring are detachably connected to the injection tube.

[0017] Preferably, the positions of the first limiting ring and the second limiting ring on the injection tube are fixed, and the insertion end of the injection tube can be cut into a suitable length according to the insertion depth.

[0018] Specifically, before enema treatment, the patient's anus is treated accordingly. After the treatment, one end of the flexible tube of the injection tube is inserted into the anus and enters the rectum and colon. The balloon is placed at the anus, the deflation valve is in a closed state, and the inflated balloon is squeezed to reach the opening pressure of the one-way valve. After the one-way valve is opened, gas continuously inflates the inside of the balloon. The one-way valve only allows gas to flow from the inflated balloon to the balloon, and the air inlet valve replenishes air accordingly, so that the outer wall of the balloon is in close contact with the inside of the anus, which then plays a role in fixing the position.

[0019] Then open the injection valve and inject drugs for treating hepatic encephalopathy, such as lactulose. Depending on the situation, you can open the drug injection valve to inject enema, antibiotics, etc. The flow rate can be adjusted by adjusting the opening size of the injection valve and the drug injection valve.

[0020] After the drug injection is completed, close the injection valve and the drug injection valve. The drug needs to be retained in the body for a sufficient time. After the time is up, open the deflation valve to allow the balloon to retract and withdraw from the injection tube, thus completing the retention enema treatment.

[0021] The beneficial effects of the utility model are:

[0022] The utility model realizes fixing the position of the injection tube during the enema process by using the injection tube and the airbag assembly in coordination. The injection tube is a soft tube and only one balloon is provided to fix the position of the injection tube, thereby improving the comfort of the patient and preventing leakage at the anus of the patient.

[0023] The utility model is provided with a balloon and a ventilation sleeve sleeve on the injection tube, and the inflatable balloon is inflated with air through the inflation tube and the ventilation sleeve, so that the balloon expands and fits tightly to the anus, and during the inflation process, air leakage accidents are prevented, thereby ensuring the accuracy of operation and improving the operation efficiency.

[0024] The utility model arranges a one-way air valve on the inflation pipe, so that the gas flows in one direction, avoids gas backflow, and accelerates the inflation speed.

[0025] By adopting the above scheme, the utility model can fix the position of the enema device during the enema process, prevent leakage from the patient's anus, and at the same time, the operation is simple, the patient's comfort is improved, and air leakage accidents are avoided, thereby ensuring the accuracy of the enema process.
