Technical Field
[0001] The utility model relates to the technical field of nasojejunal tubes, in particular to an auxiliary visual guiding device for nasojejunal tubes. Background Art
[0002] A nasojejunal tube is a commonly used medical device in clinical practice. It is a long tube made of medical plastic that is inserted from the nostril to the jejunum. Its main function is to directly input nutrients into the intestine through the nose to provide nutritional support to the human body. A guiding device is required when inserting the nasojejunal tube into the patient's body. The "A nasojejunal tube auxiliary visual guiding device" disclosed in the announcement number "CN208741530U" has solved the problem that the adhesion of secretions can easily cause the camera to be blurred, making it impossible to accurately place the tube, which is inconvenient to implement.
[0003] Although there are technical disadvantages, there are still many defects in devices with similar structures in actual use. For example, when inserting the nasojejunal tube into the patient's body, most medical staff operate it by manual grip, which will cause the surface of the nasojejunal tube to be contaminated. At the same time, the force cannot be controlled during manual grip, which may cause the nasojejunal tube to be bent during insertion, thereby increasing the difficulty for medical staff to insert the nasojejunal tube into the patient's body. At the same time, the function is relatively single, and there is no function of cleaning the inside through the device. When the nasojejunal tube is placed in the patient's body for a long time, nutrient solution will remain on its inner wall, which will breed bacteria, thereby causing infection in the patient's body. Therefore, it is necessary to design an auxiliary visual guidance device for the nasojejunal tube. Utility Model Content
[0004] The purpose of the utility model is to provide a nasojejunal tube auxiliary visual guiding device to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an auxiliary visual guidance device for a nasojejunal tube, comprising an intestinal tube main body, an operating clamp and an auxiliary catheter, wherein an assembly set is fixedly installed on the top of the intestinal tube main body, a spring rod is fixedly installed inside the auxiliary catheter, and a visual probe is fixedly installed on the bottom of the auxiliary catheter, an endoscope lens and an LED lamp bead are respectively fixedly installed on the bottom of the visual probe, and a data cable is fixedly connected to the top of the visual probe, three groups of clean air rings are fixedly installed on the lower part of the outside of the auxiliary catheter, an air guide tube is fixedly installed inside the auxiliary catheter, and the bottom of the air guide tube is fixedly connected to the three groups of clean air rings through a connecting tube, an air bag is fixedly connected to the top of the air guide tube, a holding rod is fixedly installed on the top of the intestinal tube main body, splints are fixedly installed on both ends of the operating clamp, and a card slot is provided on the inner side of the splint.
[0006] The invention discloses a nasojejunal tube auxiliary visual guiding device using the technical solution. The auxiliary catheter can be inserted into the intestinal tube body to support the inside thereof. At the same time, the spring rod inside the auxiliary catheter can support the inside of the intestinal tube body and provide flexibility, thereby increasing the hardness and flexibility of the intestinal tube body during use, avoiding bending of the intestinal tube body when inserted into the patient's body by medical staff, and improving the convenience of the staff in inserting the intestinal tube body. The holding rod is convenient for medical staff to hold the tail end of the intestinal tube body when inserted into the patient's body. The operation clamp is closed so that the card slot in the splint is clamped on the outer wall of the intestinal tube body, thereby facilitating the operation of the medical staff to insert the intestinal tube body through the operation clamp and the splint. The operation clamp is used to avoid the medical staff from operating the intestinal tube body by manual holding. The cleanliness of the intestinal tube body during insertion operation is increased by regular disinfection of the operation clamp, avoiding the surface contamination caused by the medical staff manually holding the intestinal tube body, and increasing the safety of the medical staff when inserting the intestinal tube body into the patient's body.
[0007] The endoscope lens on the visual probe can take video when the intestinal tube body enters the patient's body, and the LED lamp beads can illuminate the endoscope lens when shooting, so it is convenient for medical staff to observe when the intestinal tube body is inserted into the patient's body. The data cable is convenient for transmitting the data taken by the visual probe. The medical staff can inflate and prop up the cleaning air ring by pressing the air bag and cooperating with the airway tube. The cleaning air ring contacts the inner wall of the intestinal tube body when it is inflated with air. When the medical staff extracts the inflated cleaning air ring through the auxiliary catheter, the nutrient solution remaining on the inner wall of the intestinal tube body can be scraped and cleaned, which increases the cleanliness of the intestinal tube body when it is placed in the patient's body for a long time, avoids the situation where the nutrient solution remaining on the inner wall for a long time breeds bacteria and causes infection in the patient, increases the functionality of the device, and improves the safety of the intestinal tube body when it is placed in the patient's body for a long time;
[0008] The assembly sleeve facilitates the insertion of the intestinal tube main body into the patient's body and the connection with the external injection device, thereby facilitating the external injection device to inject nutrient solution into the patient's body through the assembly sleeve and the intestinal tube main body. The closing plate can close the top of the assembly sleeve when the auxiliary catheter is inserted into the intestinal tube main body. At the same time, the sealing plug increases the sealing performance of the closing plate when the assembly sleeve is closed, thereby preventing foreign matter from entering the patient's body through the assembly sleeve and the intestinal tube main body when medical staff insert the intestinal tube main body.
[0009] Preferably, a closing plate is fixedly mounted at the bottom of the gripping rod, and a sealing plug is fixedly mounted at the bottom of the closing plate. The closing plate can close the top of the assembly sleeve when the auxiliary catheter is inserted into the intestinal tube body, and the sealing plug increases the sealing performance of the closing plate when closing the assembly sleeve.
[0010] Preferably, one end of the data line is fixedly connected with a spring line, and one end of the spring line is fixedly installed with a connector. The connector facilitates the data line to be connected to an external display device, and the spring line can elastically extend and contract the length of the data line.
[0011] Preferably, a rubber pad is fixedly installed on the inner wall of the slot, and an anti-skid protrusion is fixedly installed on the inner wall of the rubber pad. The rubber pad can provide flexible protection when the clamp clamps the outer wall of the intestinal tube body to avoid wear on the surface of the intestinal tube body. At the same time, the anti-skid protrusion increases the friction of the inner wall of the rubber pad, thereby improving the stability of the clamp clamping the intestinal tube body.
[0012] Preferably, an air valve is fixedly connected to the upper part of the air guide tube, and a valve stem is fixedly installed on the air valve. The air valve can cooperate with the valve stem to open and close the air guide tube, and by closing the air valve, the cleaning air ring is always kept full of air, which is convenient for the cleaning air ring to clean the inner wall of the intestinal tube body.
[0013] Preferably, the outer wall of the gripping rod is fixedly mounted with an anti-slip ring, and the outer wall of the operating clamp is fixedly mounted with anti-slip grooves. The anti-slip ring increases the friction of the outer wall of the gripping rod, improving the stability of the medical staff when holding it, and the anti-slip grooves increase the friction of the outer wall of the operating clamp, improving the stability of the medical staff when operating the operating clamp.
[0014] Compared with the prior art, the beneficial effects of the utility model are:
[0015] 1. By setting the coordination between the auxiliary catheter and the spring rod, the operating clamp and the splint, the auxiliary catheter and the spring rod are inserted into the inside of the nasojejunal tube, so that the auxiliary catheter and the spring rod support the inside of the nasojejunal tube when it is inserted into the patient's body, increase the hardness and flexibility of the nasojejunal tube, avoid bending of the nasojejunal tube during the insertion operation of the medical staff, so as to facilitate the medical staff to insert the nasojejunal tube into the patient's body. The operating clamp and the splint facilitate the staff to clamp the nasojejunal tube when inserting it into the patient's body, avoid the situation where the medical staff cannot insert the nasojejunal tube by hand-holding operation, and reduce the risk of contamination of the outer wall of the nasojejunal tube.
[0016] 2. By setting up the coordination between the cleaning air ring, the airway tube and the airbag, the airbag and the airway tube can inflate the cleaning air ring. When the cleaning air ring is filled with gas, the staff can scrape off the nutrient solution remaining on the inner wall of the nasojejunal tube when pulling out the auxiliary catheter from the nasojejunal tube, thereby avoiding the situation where the nutrient solution remaining on the inner wall of the nasojejunal tube breeds bacteria when the nasojejunal tube is used for a long time. Therefore, the functionality of the device is increased, and the safety of the nasojejunal tube when it is placed in the patient's body for a long time is improved. BRIEF DESCRIPTION OF THE DRAWINGS
