Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a feeding catheter fixation device. Background Technology

[0002] A feeding tube (also known as a feeding tube or feeding tube) is a medical device used to provide nutritional support to patients who are unable to eat normally by mouth. It ensures that patients receive the necessary energy and nutrition by delivering nutrients directly to the digestive tract (such as the stomach or small intestine). Nasogastric tubes and nasoenteric tubes are two types of feeding tubes, both of which are inserted into the nostrils and require a fixation device to secure them. A search revealed that Chinese Patent CN215024803U discloses a nasogastric tube fixation device, including a medical cap, a fixation component, and a fixation sleeve. The medical cap has fixation grooves fixedly installed on both the left and right ends of its inner side, and a fixation block is provided on the outer side of the medical cap. The fixation block passes through the medical cap and is fixedly connected to the fixation groove. A fixation component is fixedly installed on the outer side of the fixation block, and a nasogastric tube is fixedly installed in the middle of the fixation component. The distal end of the nasogastric tube passes through and is fixedly installed in the middle of the inner cavity of the fixation sleeve.

[0003] The existing feeding catheter fixation devices have the following drawbacks in practical use: The feeding tubes used by children and adults are of different thicknesses. However, the existing feeding tube fixing devices are not convenient for fixing feeding tubes of different thicknesses. Each type of feeding tube fixing device can only fix feeding tubes of one thickness, which limits its application range and is not conducive to market promotion. Utility Model Content

The fixing block 206 has a supporting block 210 on the outer wall of its top. The inner walls on both sides of the fixing sleeve 201 are provided with spring grooves 208, and the inner walls of the spring grooves 208 are provided with pull springs 209 connected to the fixing block 206. The outer wall on one side of the fixing sleeve 201 is provided with a guide hole 211, and the inner wall of the fixing sleeve 201 is provided with a guide block 207. The fixing block 206 is slidably sleeved on the outside of the guide block 207.

[0021] In specific implementations, such as Figure 1 and Figure 4 As shown, a rotating assembly 3 is provided on the outer wall of the fixed sleeve 201. The rotating assembly 3 includes a rotating disk 301, a fixed cylinder 302 and an insertion hole 304. The rotating disk 301 is fixedly disposed on the outer wall of the fixed sleeve 201. The rotating assembly 3 is used to rotate and fix the fixed sleeve 201.

[0022] Furthermore, the fixed cylinder 302 is fixedly mounted on the outer wall of the top of the rotating disk 301, and the fixed cylinder 302 is slidably connected to the inside of the fixed cylinder 302, so that the fixed cylinder 302 can rotate when the rotating disk 301 rotates.

[0027] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview: In use, support plate 1 is placed on the outside of the nose, and straps 4 and 6 are wrapped around the back of the patient's head. The Velcro adhesive side 5 is attached to the Velcro hook side 7, allowing the nutrition catheter fixation device to be quickly secured to the patient's head. Then, lifting plate 306 moves the insertion rod 303 out of the insertion hole 304. Rotating disc 301 rotates the fixing sleeve 201, turning the catheter hole 211 to different directions. Since the nutrition catheter is inserted through the catheter hole 211, the insertion direction of the nutrition catheter can be adjusted. Releasing lifting plate 306 allows the elastic force of the retaining spring 307 to... The insertion rod 303 is pushed down and inserted into the insertion hole 304 to fix the fixing sleeve 201. Then, the nutrition catheter is inserted into the fixing sleeve 201 through the catheter hole 211 and through the fixing sleeve 201 into the patient's nasal cavity. The fixing screw 202 is rotated to move the squeezing block 203 down. The squeezing block 203 squeezes the inclined surface of the supporting block 210, which can make the supporting block 210 move the fixing block 206. The two fixing blocks 206 can fix nutrition catheters of different thicknesses, so that the nutrition catheter fixing device can fix nutrition catheters of different thicknesses, and the range of applications is wider.
