Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a precision-calibrated lubricated enema catheter assembly. Background Technology

[0002] An enema catheter is a medical device used for enema procedures. An enema involves inserting a catheter into the patient's anus and injecting an appropriate amount of liquid and medication to cleanse the intestines, stimulate defecation, or provide therapeutic effects.

[0003] Existing lubricating enema catheter assemblies typically include a syringe and a catheter. Lubricating enemas are usually treated with glycerin suppositories. When the syringe draws up the suppository solution, the healthcare worker inserts the catheter into the syringe tip, then inserts the catheter into the patient's anus. When the catheter reaches the designated depth, the syringe plunger is pushed to complete the drug injection.

[0004] Existing enema catheters are usually made of rubber or latex. Because latex is soft, it is easy for medical staff to bend and deform during insertion, which affects the stability of the catheter insertion and thus the efficiency of enema treatment. At the same time, the accuracy of catheter insertion also affects the effect of enema treatment. Utility Model Content

[0005] To overcome the problem that existing enema catheters are usually made of rubber or latex, which are soft and easily bent and deformed by medical staff during insertion, thus affecting the stability of the catheter insertion and the efficiency of enema treatment, as well as the accuracy of catheter insertion, thus affecting the effect of enema treatment.

[0006] The technical solution of this utility model is as follows: a precision-scaled lubricated enema catheter assembly, including a syringe, a guide assembly, and a piston assembly. The syringe includes a barrel, with a first connecting seat fixed at the end of the barrel. A first needle is inserted into the middle of the first connecting seat. The guide assembly includes a tubing, a second connecting seat, and a second needle. The second connecting seat is threaded to the outer surface of the first connecting seat. The tubing is sleeved on the second connecting seat. The second needle is inserted into the other end of the tubing. Two shaping wires are snapped into the middle of the tubing. A second scale line is engraved on the side wall of the tubing. The piston assembly includes a guide rod that is slidably connected to the middle of the barrel.

[0007] Furthermore, a connecting tube is inserted in the middle of the second connecting seat, and an anti-slip groove is provided on the surface of the connecting tube. The rubber tube is sleeved on the outer surface of the connecting tube, and the first needle penetrates the connecting tube and connects with the rubber tube, which improves the stability of the cylinder connection.

[0008] Furthermore, the two shaping filaments are symmetrically distributed, and the ends of the shaping filaments are respectively fixed on the side arm of the second needle. The end of the second needle is chamfered, which improves the stability of the second needle installation.

[0009] Furthermore, several retaining rings are snapped onto the inner wall of the tubing. The retaining rings are all circular and linearly distributed, and are fixed to the inner walls of the two shaping wires, which improves the overall stability of the shaping wires.

[0010] Furthermore, the cylinder, the first connecting seat, and the first needle are fixedly connected to form an integral structure. The external dimensions of the first connecting seat are adapted to the internal dimensions of the second connecting seat, which improves the stability of the second connecting seat installation.

[0011] Furthermore, a first scale line is engraved on the side wall of the cylinder, and two support plates are symmetrically fixed at the end of the cylinder away from the first connecting seat.

[0012] Furthermore, a cylindrical head is fitted onto one end of the guide rod to match the internal dimensions of the cylinder, thereby improving the sealing performance of the cylinder.

[0013] Furthermore, four wing plates are fixed on the side wall of the guide rod, and a pad is fixed on the other end of the guide rod, which improves the stability of the guide rod sliding.

[0014] The beneficial effects of this utility model are:

[0015] Compared to traditional precision-scaled lubrication enema catheter assemblies, this device improves the stability of tubing installation through the cooperation of the first and second connecting seats. The second needle, in conjunction with the tubing, prevents the tubing end from bending and becoming blocked. The second needle, in conjunction with the shaping wire, enhances the stability of its installation. The shaping wire, in conjunction with the tubing, improves the overall toughness of the tubing, thus increasing the overall stability of the tubing insertion. Observing the second scale reading facilitates control of the tubing insertion depth, thereby improving the efficiency and accuracy of lubrication enema treatment. Furthermore, the inclusion of a retaining ring, which is circular and used for support and limitation, enhances the overall stability of the two shaping wires. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Among the currently discovered feasible technologies, the following are described:

[0024] A lubricated enema catheter assembly is a medical device used for enema procedures, typically consisting of a catheter, lubricant, and related auxiliary components.

[0025] Catheters: Generally made of soft, smooth medical-grade materials, such as silicone or polyvinyl chloride (PVC). Catheters are available in various diameters and lengths to suit different age groups and individual needs. Their tips are usually designed with a rounded shape to reduce damage to the intestinal mucosa.

[0026] Lubricant: This is an important component for lubricating enema catheter assemblies and is usually a water-soluble lubricant. It can be evenly applied or coated onto the catheter surface, or it may be pre-installed at specific points on the catheter, such as the tip or outer layer. The function of the lubricant is to reduce the coefficient of friction between the catheter and the intestinal wall, allowing the catheter to be inserted into the intestine more smoothly, reducing patient discomfort and damage to the intestinal mucosa.

[0027] Auxiliary components: These may include syringes, connectors, etc. The syringe is used to inject the enema solution into the intestine through a catheter, while the connector is used to connect the catheter to the syringe or other enema solution container to ensure a tight connection and prevent leakage of the enema solution.

[0028] Lubrication: A lubricating film is formed between the catheter and the intestinal mucosa by the lubricant, reducing friction between them. This allows for smoother insertion of the catheter into the intestine, reducing patient pain and discomfort, and also helps avoid complications such as intestinal mucosal damage and bleeding caused by friction.

[0029] Enema delivery: Using pressure generated by a syringe or other enema delivery device, enema fluid is injected into the intestine through a catheter. Enema fluid serves to cleanse and lubricate the intestines, promote defecation, or may be used in certain drug treatments.

[0030] Treatment for constipation: For patients with chronic constipation or difficulty defecating due to various reasons, lubricated enema catheter components can help cleanse the intestines, stimulate intestinal peristalsis, promote stool excretion, and relieve constipation symptoms.

[0031] Preparation before bowel examination: Before undergoing bowel-related examinations such as colonoscopy and bowel X-ray, it is necessary to cleanse the intestines to ensure the accuracy of the examination results. A lubricated enema catheter assembly can be used for enemas to remove feces and impurities from the intestines, creating favorable conditions for the examination.

[0032] Enema therapy: For certain diseases such as ulcerative colitis and proctitis, enemas are used to deliver medication directly to the affected area for local treatment. Lubricated enema catheters can accurately deliver medication to the intestinal lesion, improving therapeutic efficacy.

[0033] Strictly adhere to aseptic techniques: Before using the lubricated enema catheter assembly, ensure that all components undergo rigorous sterilization to prevent intestinal infection.

[0034] Choose the appropriate catheter size: Select a catheter with an appropriate diameter and length based on the patient's age, weight, condition, and other factors to avoid damage to the intestines caused by a catheter that is too thick or too long.

[0035] Use lubricant correctly: Ensure the quality and safety of the lubricant, and apply or use it correctly according to the instructions. Improper use of lubricant may affect the lubrication effect or even cause adverse reactions.

[0036] Handle gently: When inserting the catheter, move gently and avoid rough handling. If resistance is encountered, do not force insertion; identify the cause and take appropriate measures, such as adjusting the catheter angle or stopping the procedure.

[0037] Observe the patient's reaction: During the enema, closely observe the patient's complexion, expression, vital signs, etc. If the patient experiences discomfort such as abdominal pain, palpitations, or sweating, the enema should be stopped immediately and appropriate treatment should be given.

[0038] Glycerin suppositories are a common medication used to treat constipation and can be administered via enema. The main components of glycerin suppositories are: there are two common formulations, one containing glycerin and the other containing mannitol and magnesium sulfate. Both formulations have similar mechanisms of action, utilizing the hypertonic effect of glycerin or sorbitol to allow more water to penetrate the intestinal lumen, softening the stool, stimulating the intestinal wall, and reflexively inducing a defecation reflex. Simultaneously, glycerin suppositories lubricate the intestinal wall, making bowel movements easier.

[0039] It is mainly used to treat functional constipation, especially for patients with hard stools and difficulty in defecation who cannot be relieved by dietary adjustments and increased exercise. In addition, glycerin suppositories are also a commonly used laxative for people prone to constipation, such as those who are bedridden for extended periods, the elderly, and postpartum women. In some special circumstances, such as before a bowel examination or surgery, glycerin suppositories may also be used to cleanse the intestines and promote defecation.

[0040] Existing enema catheters are usually made of rubber or latex. Because latex is soft, it is easy for medical staff to bend and deform during insertion, which affects the stability of the catheter insertion and thus the efficiency of enema treatment. At the same time, the accuracy of catheter insertion also affects the effect of enema treatment.

[0041] Example 1

[0042] The precision-calibrated lubrication enema catheter assembly includes a syringe 1, a guide assembly 2, and a piston assembly 3. The syringe 1 includes a cylindrical body 101 made of transparent plastic. The cylindrical body 101 is used to hold the enema solution, specifically a glycerin suppository, a common topical medication used to treat constipation. Glycerin suppositories utilize the hypertonic effect of glycerin or sorbitol to allow more water to penetrate the intestinal lumen, softening the stool and stimulating the intestinal wall, reflexively inducing defecation. Furthermore, glycerin suppositories lubricate the intestines, making defecation easier. After being discharged from the body, the end of the cylinder 101 is fixed with a first connecting seat 102 for connection and positioning. A first needle 103 is inserted into the middle of the first connecting seat 102. The sharp end of the first needle 103 is used to insert into the mouth of the enema bottle to draw the medicine. The guide assembly 2 includes a rubber tube 201, a second connecting seat 202, and a second needle 203. The rubber tube 201 is made of latex and is cylindrical. The total length of the rubber tube 201 is between 15-30 cm. The length of the rubber tube 201 can be customized according to requirements. The second connecting seat 202 is threaded to the first... The outer surface of the connector 102 allows for the installation of the hose 201. The cylinder 101 and the hose 201 are connected. The hose 201 is fitted onto the second connector 202. The second needle 203 is inserted into the other end of the hose 201. The second needle 203 is made of stainless steel to prevent the end of the hose 201 from bending and becoming blocked. Two shaping wires 204 are clamped in the middle of the hose 201. The shaping wires 204 are made of copper wire and have good plasticity. The side wall of the hose 201 is engraved with a second scale line 205. The second connector 202... A connecting tube 207 is inserted in the middle of the cylinder 101. The surface of the connecting tube 207 is provided with anti-slip grooves. The rubber tube 201 is fitted onto the outer surface of the connecting tube 207 by hot-melt welding. The first needle 103 penetrates the connecting tube 207 and is connected to the rubber tube 201, which improves the stability of the cylinder 101 connection. The piston assembly 3 includes a guide rod 301 that is slidably connected in the middle of the cylinder 101. One end of the guide rod 301 is fitted with a column head 302. The column head 302 is cylindrical and matches the internal dimensions of the cylinder 101, which improves the sealing performance of the cylinder 101.

[0043] Two shaping wires 204 are symmetrically distributed, and the ends of the shaping wires 204 are respectively fixed on the side arm of the second needle 203. The end of the second needle 203 is chamfered to avoid scratching the patient and improve the stability of the second needle 203 installation.

[0044] The cylinder 101, the first connecting seat 102, and the first needle 103 are fixedly connected to form an integral structure. The external dimensions of the first connecting seat 102 are adapted to the internal dimensions of the second connecting seat 202, which improves the stability of the installation of the second connecting seat 202. The side wall of the cylinder 101 is engraved with a first scale line 104, which is used for medical staff to observe and control the amount of medicine absorbed. Two support plates 105 are symmetrically fixed at the end of the cylinder 101 away from the first connecting seat 102. The two support plates 105 are used for support and limiting, which improves the stability of gripping.

[0045] When using this precise-scale lubricated enema catheter assembly, medical staff first prepare the enema solution, then hold the cylinder 101 and insert the first needle 103 below the surface of the solution. Next, they pull the guide rod 301 upwards, causing the tip 302 to slide upwards, allowing the solution to enter the cylinder 101 under negative air pressure. Then, they thread the second connecting seat 202 onto the end of the first connecting seat 102, allowing the first needle 103 to penetrate 107, thus connecting the cylinder 101 and the tubing 201. When medical staff need to insert the tubing 201 into the patient's anus, they can first lubricate the surface of the tubing 201 with paraffin-oiled cotton pads, and then use gauze in their left hand to separate the buttocks to expose the anus for easier insertion of the tubing 201. The paraffin-oiled cotton pads and gauze are existing technologies and will not be described in detail here. Two shaping wires... 204, through support and limiting, can reduce the bending range of the tubing 201, thereby improving the stability of the tubing 201 insertion. Medical staff can precisely control the insertion depth of the second needle 203 by observing the second scale line 205. The second needle 203 is made of stainless steel and has rigidity to prevent the tubing 201 from bending and blocking. The second needle 203 and the shaping wire 204 can improve the installation stability of the second needle 203. When inserted to the designated depth, the medical staff push the guide rod 301 to inject the medicine from the cylinder 101 along the first connecting seat 102, the first needle 103, the tubing 201 and the second needle 203 into the patient's anus and rectum. After the enema is completed, the tubing 201 is slowly pulled out, and the patient is instructed to retain the liquid for 5-10 minutes before defecating, thereby improving the efficiency and accuracy of the lubricating enema treatment.

[0046] Example 2

[0047] Several retaining rings 206 are snapped onto the inner wall of the tubing 201. The retaining rings 206 are all circular and linearly distributed. The retaining rings 206 are fixed to the side walls of the two shaping wires 204 by welding, which improves the overall stability of the shaping wires 204. Four wing plates 304 are fixed on the side wall of the guide rod 301, which improves the overall stability of the guide rod 301. A pad 303 is fixed at the other end of the guide rod 301. The pad 303 is used to increase the contact surface for medical staff to press with their fingers, thereby reducing the pressure and improving the convenience and stability of the sliding of the guide rod 301.

[0048] When medical staff insert the tubing 201 into the patient's anus and rectum, several shaping wires 204 can be supported and limited to prevent the shaping wires 204 from sticking together under anal pressure, thereby preventing the tubing 201 from becoming blocked and improving the stability of the flow of medication through the tubing 201.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
