Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a nasogastric tube fixing device. Background Art

[0002] Clinically, some patients have loss of consciousness or difficulty swallowing and eating. At this time, food needs to be directly injected into the stomach through a gastric tube for digestion. This method is cheaper and healthier than parenteral nutrition preparations. The existing gastric tube feeding fixing device is mainly composed of a gastric tube and adhesive tape. When in use, the gastric tube is inserted into the patient's body through the patient's nasal cavity, and then the gastric tube is fixed to the patient's nose through adhesive tape, and food is injected into the patient's body from the outer end of the gastric tube, thereby achieving gastric tube feeding. However, the existing fixing method of directly sticking the tape on the nose has the following defects: 1. This fixing method relies on the viscosity of the adhesive tape. After the patient's nasal skin produces secretions, the adhesive tape is easily reduced, resulting in the adhesive tape being not firmly fixed and easy to fall off. At this time, it is necessary to repeatedly stick it, which will not only cause skin damage and allergies, but also increase the working time of nursing staff; 2. During the fixation period, the patient touches the gastric tube unconsciously, which causes the adhesive tape to fall off, which may cause the patient to accidentally inhale excess gastric tube into the body and cause medical accidents.

[0003] In view of this, in order to solve the above-mentioned technical problems, the present invention proposes a fixing device that solves the problem of skin damage caused by repeated sticking of adhesive tape, ensures the safety of blood supply to the nasal mucosa, reduces the risk of ischemic damage, and avoids medical accidents caused by aspiration of gastric tubes. Summary of the invention

[0004] The present invention provides a nasogastric tube fixing device, which solves the problem of skin damage caused by repeated sticking of adhesive tape, ensures the safety of nasal mucosal blood supply, reduces the risk of ischemic injury, and avoids medical accidents caused by gastric tube aspiration.

The nasal stent 3 can be customized according to the 3D scan data of the patient's nose. The fixing member 1 is an arc-shaped structure and is located on the upper lip under the nose. The nasal stent 3 is connected to the fixing member 1 through an inverted L-shaped connecting rod 5. The connecting rod 5 is made of rigid plastic. Symmetrically arranged mounting members are provided on one side of the fixing member 1. The mounting members are made of rigid plastic. An arc-shaped adjusting strap 6 is connected between the two mounting members. A first loose sleeve 7 is sleeved on the adjusting strap 6. The first loose sleeve 7 can be manually adjusted on the adjusting strap 6. A first clamping groove 4 in the same direction as the nostril is fixedly provided on the side of the first loose sleeve 7 facing away from the fixing member 1. The first clamping groove 4 is used for clamping and fixing the gastric tube, which can prevent the gastric tube from moving back and forth. The two ends of the binding strap 2 are respectively connected to the two ends of the fixing member 1. A nano-level flexible pressure sensor is embedded in the nasal stent 3. The pressure sensor is connected to the controller through a signal line. The controller is connected to the monitoring terminal through a wireless signal. The design of the monitoring terminal facilitates the transmission of signals through the pressure sensor when the patient accidentally touches or pulls the gastric tube and causes it to shift, so that medical staff can discover it in time and achieve early detection and early intervention.

[0023] Preferably, there are two binding straps 2, and one end of each of them is detachably connected to the two ends of the fixing member 1 through an adhesive member. A magic tape 8 is provided on one of the binding straps 2, and the fixing connection between the two binding straps 2 can be completed through the magic tape 8, so that the device can be fixed.

[0024] Preferably, connecting heads are respectively provided on the opposite sides of the mounting member. The two ends of the adjusting strap 6 are respectively fixedly connected with U-shaped members 9. The two U-shaped members 9 are respectively rotatably connected to the connecting heads of the two side mounting members, which is convenient for the disassembly and assembly of the adjusting strap 6.

[0025] Preferably, a second loop 10 is sleeved on the adjusting belt 6 on one side of the first loop 7, wherein the second loop 10 can be manually adjusted on the adjusting belt 6, and a second clamping groove 11 is fixedly connected to the side of the second loop 10 away from the fixing member 1, and the second clamping groove 11 is staggered with the first clamping groove 4, wherein the setting of the second clamping groove 11 can limit and fix the outer end of the gastric tube, further strengthen the fixation of the gastric tube to prevent it from falling off and causing aspiration by the patient.

[0026] Preferably, one side of the first clamping groove 4 and the second clamping groove 11 is provided with a plurality of clamping holes 12 spaced apart along the arc direction thereof, and the other side wall is provided with a clamping joint suitable for the clamping holes 12, wherein the design of the clamping holes 12 and the clamping joint facilitates the adjustment of the inner diameter of the clamping groove to accommodate various types of gastric tubes.

[0027] The preferred fixing member 1 comprises two symmetrically arranged fixing belts and a fixing sleeve 13, wherein the lower sides of the opposite ends of the two fixing belts are respectively provided with latch teeth, and the fixing sleeve 13 is provided with a plurality of latch grooves suitable for the latch teeth at even intervals along its arc direction, and the fixing belts on both sides can be adjusted to adapt to faces of different sizes.

[0028] Preferably, the inner sides of both ends of the fixing member 1 are connected with sponge pads 14 respectively, wherein the two sponge pads 14 can be placed on both sides of the cheeks respectively, so as to reduce the pressure caused by the fixing of the strap 2 and improve the comfort.

[0029] Preferably, the nose-shaped bracket 3 and the first clamping groove 4 are both made of silicone material, and the fixing member 1 and the adjusting belt 6 are both made of flexible and transparent rubber material.

[0030] Preferably, an alarm is provided on the monitoring terminal, and the alarm is connected to the controller via a signal line.

[0031] The working principle of the present invention is as follows: when in use, first adjust the length of the two fixing belts according to the size of the face. When adjusting, just push the snap teeth on the fixing belt into the snap groove in the fixing sleeve 13, then place the fixing part 1 on the upper lip under the nose, and then stick the nose-shaped bracket 3 made of silicone material on the nose. It can be fixed by using its strong adhesiveness so that it is not easy to fall off. Then, pass the strap 2 around the back of the head and use Velcro 8 to bond it. The medical staff inserts the gastric tube into the patient's stomach from the nostrils, then clips the gastric tube into the first snap groove 4 and the snap joint on it into the snap hole 12 to limit and fix the gastric tube, and then clips a section of the outer end of the gastric tube into the second snap groove 11 to complete the limit and fixation of the gastric tube.
