Description

Technical Field

[0001] The utility model relates to the technical field of gastric auxiliary treatment devices, in particular to a mirror tube bite preventer. Background Art

[0002] In clinical practice, oral gastric tubes can deliver food or medicine to the patient's stomach, or extract gastric juice through the oral gastric tube. The oral gastric tube is inserted through the mouth and reaches the stomach through the pharynx and esophagus. When using an oral gastric tube, it is usually inserted into the stomach through the mouth and needs to be fixed.

[0003] However, most existing oral gastric tubes are fixed by wrapping the tube with adhesive tape and sticking it on the cheeks of the patient on both sides. The stickiness of the tape will weaken with the use time, and it cannot be fixed well. In addition, the adhesive tape will cause strong discomfort to the patient and even cause skin allergies. Utility Model Content

[0004] The utility model aims to provide a mirror tube bite preventer with good fixing effect.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0007] It can be seen that the gastric tube is placed in the sleeve in advance, and the first fastener and the second fastener are respectively screwed to fix the gastric tube in the sleeve. After the upper and lower kits are pressed to shrink to the minimum, they are placed in the patient's mouth and fixed. By using the telescopic component, the distance between the upper and lower kits can be adjusted according to the size of the patient's mouth opening. The patient can open and close his mouth slightly during use to avoid the patient opening his mouth widely all the time, relieve the patient's mouth, and feel more comfortable. The tight component can centrally absorb the saliva produced when the patient opens his mouth to avoid the patient feeling ashamed due to excessive saliva flowing out after opening the mouth all the time. It is more practical.

[0008] Furthermore, the telescopic assembly includes a telescopic tube, an extension rod and a spring, and a tube inner cavity is opened in the telescopic tube; the telescopic tube is installed above the lower kit, and an extension rod is telescopically installed in the tube inner cavity, and the upper part of the extension rod is fixedly connected to the lower surface of the upper kit; one end of the spring is connected to the inner bottom wall of the tube inner cavity, and the other end of the spring is connected to the lower surface of the extension rod.

[0009] When the patient opens the mouth widely for a long time and experiences mouth soreness, the patient can slightly close the mouth and squeeze the upper kit downward. When the force applied to the upper kit stops, the upper kit is reset under the elastic force of the spring, and the patient's mouth returns to its original position. By using the telescopic component, the patient can slightly open and close the mouth without affecting the sleeve, avoiding the soreness of the mouth caused by opening the mouth widely for a long time, thereby improving the patient's mouth comfort.

[0010] Furthermore, the tight assembly includes an elastic seal and absorbent cotton, a sealing cavity is opened in the elastic seal, flow holes are opened on both sides of the upper surface of the elastic seal, and the sealing cavity and the flow holes are communicated; the elastic seal is tightly installed on the lower surface of the lower kit, and the front and rear sides both extend beyond the lower kit; absorbent cotton is removably installed in the sealing cavity.

[0011] After opening the mouth for a long time, the saliva flowing out flows into the sealed cavity through the circulation holes and is absorbed by the absorbent cotton, thus preventing the saliva from flowing out, alleviating the patient's shame, and being more practical.

[0012] Furthermore, a first receiving groove is provided on the upper kit, and the first receiving groove is used to receive the patient's upper teeth; a second receiving groove is provided on the lower kit, and the second receiving groove is used to receive the patient's lower teeth.

[0013] By fixing the upper kit and the lower kit on the upper and lower teeth of the patient respectively, the fixing effect is better.

[0014] Furthermore, protrusions are equidistantly arranged on the inner wall of the sleeve.

[0015] The use of the protrusion can increase the friction between the sleeve and the gastric tube, which is beneficial to the fixation of the gastric tube.

[0016] Furthermore, the edges and corners of the upper and lower kits are provided with rounded arcs.

[0017] The rounded corner setting can reduce the discomfort caused by corners to patients and improve comfort. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figure 1-3 As shown, a mirror tube bite preventer includes a sleeve 3, both ends of the sleeve 3 are provided with threads 31, and the two ends of the sleeve 3 are respectively installed with a first fastener 32 and a second fastener 33 through the threads 31; the upper end of the sleeve 3 is telescopically installed with an upper kit 1 through an upper telescopic rod 4, and the lower end of the sleeve 3 is telescopically installed with a lower kit 2 through a lower telescopic rod 41; both sides of the upper kit 1 and the lower kit 2 are provided with telescopic components 5, and the telescopic components 5 are used for telescopic adjustment between the upper kit 1 and the lower kit 2; the bottom of the lower kit 2 is provided with a tight component 6, and the tight component 6 is used to deal with saliva generated during treatment.

[0024] During specific use, the gastric tube is placed in the sleeve 3 in advance, and the first fastener 32 and the second fastener 33 are respectively screwed through the thread 31 to fix the gastric tube in the sleeve 3, and the upper kit 1 and the lower kit 2 are pressed to shrink the upper kit 1 and the lower kit 2 to the minimum, and then placed in the patient's mouth for fixation. When the mouth is opened widely for a long time and feels sour and astringent, the patient can slightly adjust the size of the mouth opening through the telescopic component 5 to avoid the patient opening the mouth widely all the time and relieve the patient's mouth. When saliva flows out, the saliva can be concentratedly absorbed through the tight component 6 to avoid the patient feeling ashamed due to the excessive saliva flowing out after opening the mouth all the time, which is more practical.

[0025] Specifically, the telescopic assembly 5 includes a telescopic cylinder 51, an extension rod 52 and a spring 53. The telescopic cylinder 51 is provided with a cylinder inner cavity 501; the telescopic cylinder 51 is installed above the lower kit 2, and the extension rod 52 is telescopically installed in the cylinder inner cavity 501, and the upper part of the extension rod 52 is fixedly connected to the lower surface of the upper kit 1; one end of the spring 53 is connected to the inner bottom wall of the cylinder inner cavity 501, and the other end of the spring 53 is connected to the lower surface of the extension rod 52. During use, when the patient opens the mouth widely for a long time and experiences soreness in the mouth, the patient can slightly close the mouth and squeeze the upper kit 1 downward to drive the telescopic tube 51 to contract in the inner cavity 501 of the tube. At this time, the spring 53 is squeezed and accumulates force, and the distance between the upper kit 1 and the lower kit 2 is reduced. When the force on the upper kit 1 stops, the elastic force of the spring 53 drives the extension rod 52 to reset, thereby driving the upper kit 1 to reset, and the patient's mouth returns to its original position. By using the telescopic component 5, the patient can perform slight mouth opening and closing movements without affecting the sleeve 3, avoiding the soreness of the mouth caused by opening the mouth widely for a long time, and improving the comfort of the patient's mouth.

The elastic seal 61 is tightly installed on the lower surface of the lower set 2, and the front and rear sides are both beyond the lower set 2. The absorbent cotton 62 is detachably installed in the sealing cavity 601. After opening the mouth for a long time, saliva will inevitably flow out. At this time, the saliva flows into the sealing cavity 601 through the flow holes 602 and is absorbed by the absorbent cotton 62, so as to avoid saliva flowing out, relieve the patient's shame, and be more practical.

[0027] Specifically, the upper kit 1 is provided with a first receiving groove for receiving the patient's upper teeth; the lower kit 2 is provided with a second receiving groove for receiving the patient's lower teeth. When in use, the upper kit 1 and the lower kit 2 are pre-shrinked to the minimum, and after being put into the patient's mouth, the upper kit 1 is fixed on the patient's upper teeth, and then the lower kit 2 is fixed on the patient's lower teeth, so that the fixing effect is better.

[0028] Specifically, protrusions 7 are equidistantly arranged on the inner wall of the sleeve 3. The use of the protrusions 7 can increase the friction between the sleeve 3 and the gastric tube, which is beneficial to fix the gastric tube.

[0029] Specifically, the edges and corners of the upper kit 1 and the lower kit 2 are rounded. The skin in the oral cavity is sensitive and easily injured, and the rounded corner setting can reduce the discomfort of the edges and corners to the patient and improve comfort.
