Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to a gastric tube fixing device for preventing pressure ulcers. Background Art

[0002] A gastric tube is a medical device that is mainly inserted through the patient's nostril or mouth, passes through the pharynx, enters the esophagus, and finally reaches the stomach. Its main function is to deliver necessary water and food to patients who cannot eat normally through the mouth, so as to maintain the normal vital signs of patients and establish an important access for enteral nutrition. Since the nasogastric tube is prone to slipping out, it should be firmly pasted to prevent repeated intubation and aspiration.

[0003] Pressure ulcers, also known as pressure sores or bedsores, are caused by long-term local tissue compression, resulting in continuous ischemia, hypoxia, and malnutrition, leading to tissue ulceration and necrosis. Pressure ulcers are common in rehabilitation treatment and nursing and are a widespread problem.

[0004] At present, there are mainly two ways to fix the gastric tube. One is to paste the gastric tube on the patient's face with tape. The skin of the patient's face where the tape is pasted is covered by the tape, and the skin tissue is prone to pressure ulcers due to lack of oxygen. The other is to tie the gastric tube on the patient's face with a strap. In order to ensure that the gastric tube is firmly fixed, the strap has a large squeezing force on the patient's facial skin, which is also likely to cause pressure ulcers on the patient's face. Summary of the Invention

[0005] The purpose of the utility model is to provide a gastric tube fixing device for preventing pressure ulcers, and to solve the problem that the existing gastric tube fixing device is prone to cause pressure ulcers. The following solutions are adopted to achieve the above purpose:

[0006] A gastric tube fixing device for preventing pressure ulcers includes: a fixing band, a strap, ear hanging bands, a gastric tube clip, Velcro, strip-shaped air bags, an air charging and discharging device, and protrusions. The fixing band is composed of three strip-shaped straps and two ring-shaped ear hanging bands at both ends spliced alternately. The front of the middle strap of the fixing band is fixedly installed with a gastric tube clip. The two sides of the fixing band are respectively provided with the rough surface and the hook surface of the Velcro. Two strip-shaped air bags are fixedly arranged inside the fixing band. The two strip-shaped air bags respectively extend from one end of the fixing band to the other end along the edge of the fixing band and fork at the ear hanging bands. The air charging and discharging device is located on one side of the fixing band and penetrates the fixing band to be communicated with the two strip-shaped air bags respectively. A number of columnar protrusions are evenly arranged on the back of the fixing band.

[0007] Furthermore, on the left and right sides of the front of the base of the gastric tube clip, a box body and a fixing splint are respectively arranged. A movable shaft that penetrates the left and right side surfaces of the box body and extends outwards is arranged inside the box body. A limiting plate is arranged on the part of the movable shaft inside the box body. One end of a spring is fixed on the left inner wall of the box body, and the other end is fixed on the left side surface of the limiting plate. The right end of the movable shaft is fixedly installed with a movable splint.

[0008] Furthermore, the extruded ball of the inflation and deflation device is hollow inside and can rebound after deformation. It is provided with an intake check valve and an exhaust check valve. The exhaust check valve is connected to a four-way joint through a conduit. The other three interfaces of the four-way joint are respectively connected to an exhaust port with a sealing cap, and two valves. The two valves are connected to two strip-shaped air bags through a conduit passing through a fixing belt.

[0009] Directions:

[0010] The medical staff places the fixing belt under the back of the patient's head, and then puts the ear straps on both sides on the patient's ears, and then fixes the fixing belt to the patient's face in a relatively relaxed state through Velcro. The medical staff then grabs the movable axis and pulls it outward, puts the part of the gastric tube that needs to be fixed into the gastric tube clamp, and then releases the hand. The spring drives the movable axis to reset, so that the movable splint and the fixed splint cooperate to fix the gastric tube. The medical staff then holds the squeezing ball of the inflation and deflation device and opens any valve. The hand continuously squeezes the squeezing ball, and through the deformation and rebound of the squeezing ball and the cooperation of the two one-way valves, the outside air is pumped into the corresponding strip air bag, and the gastric tube fixing device is fixed to the patient's face by using the expansion of the strip air bag, and the valve is closed after the inflation is completed.

[0011] After a certain period of time, the medical staff opens the valve connected to the other strip airbag, squeezes the squeezing ball, and inflates the strip airbag. After the inflation is completed, the valve on the strip airbag is closed, and then the valve of the strip airbag that was originally inflated is opened, and the sealing cap on the exhaust port is removed to deflate the strip airbag that was originally inflated, and then the sealing cap is put back on the exhaust port.

[0012] Repeat the above operation regularly, constantly changing the squeezing position of the gastric tube fixing device on the patient's face to avoid long-term pressure on the patient's facial skin tissue and the formation of pressure sores.

[0013] In addition, when using the gastric tube fixation device, the columnar protrusions on the back of the fixation belt will undergo irregular deformation under the action of pressure. Since there are gaps between the protrusions and they have a certain length, there are still certain gaps between the deformed protrusions, so that the skin tissue covered by the fixation belt can still be in normal contact with the ambient air, and hypoxia will not occur, avoiding the occurrence of pressure sores.

[0014] Advantages of the utility model

[0015] (1) The utility model arranges two strip-shaped air bags in the fixing belt and is equipped with an inflation and deflation device. By staggered inflation and deflation of the two strip-shaped air bags, the gastric tube fixing device is stably fixed on the patient's face while constantly changing the squeezing position of the gastric tube fixing device on the patient's face, thereby effectively avoiding long-term pressure on the patient's facial skin tissue and preventing the occurrence of pressure sores. At the same time, columnar protrusions are arranged on the back of the fixing belt. Because the protrusions have a certain height and there are gaps between them, when the fixing belt covers the patient's face, the skin tissue underneath it can still be in normal contact with the ambient air, and hypoxia will not occur, thereby avoiding the occurrence of pressure sores.
