Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and more specifically, relates to a multifunctional oral opening device for gastroscopy. Background Art

[0002] Gastroscopy has the advantages of being safe, easy to operate, and highly applicable. It allows for direct observation of lesions through the lens, pathological biopsy of suspected lesions to determine their nature, and direct treatment of lesions such as polypectomy. A mouth opener is used during gastroscopy. Most existing mouth openers used in gastroscopy are made of plastic, which is less expensive than other materials and is disposable, making it more hygienic.

[0003] However, gastroscopy takes a long time, and the patient's mouth always remains in a fixed open state. Leaving it in the mouth for a long time will cause a strong sense of pressure to the patient, and the patient may feel very uncomfortable. This sense of pressure may cause local pain in the patient's mouth, and even affect eating and oral activities after the examination. During the examination, saliva will continue to be secreted in the mouth, and the doctor needs to use equipment to absorb it in time to prevent the patient from entering the respiratory tract through the mouth and causing aspiration.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a multifunctional oral opening device for gastroscopy is provided, in order to achieve the purpose of having greater practical value. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a multifunctional oral opening device for gastroscopy to solve the above problems.

[0006] The purpose and effect of the multifunctional oral opening device for gastroscopy of the present invention are achieved by the following specific technical means:

[0007] A multifunctional oral opening device for gastroscopy includes an expanding tube, a lip front plate is fixedly installed on the front end of the expanding tube, an occlusive adjustment component is fixedly sleeved on the outer wall surface of one end of the expanding tube close to the lip front plate, and a water absorption component is symmetrically installed on the middle outer wall surface of the expanding tube.

[0008] Furthermore, the bite adjustment assembly includes two annular blocks fixedly sleeved on the outer wall of the flared tube in the front and rear directions, an air bag is bonded to the middle of the two annular blocks, a soft rubber air nozzle is installed on the front side wall of the air bag, and the air inlet end of the soft rubber air nozzle passes through the front side wall of the lip front plate.

[0009] Furthermore, the annular block is preferably made of silicone material.

[0010] Furthermore, the water absorption component includes a hinged head fixedly installed in the middle of the outer wall of the expanded tube, a hinged rod is rotatably installed on the hinged head, a capsule-shaped water absorption bin is fixedly installed on the other end of the hinged rod, and water inlet holes connected to the inner cavity are evenly distributed on the capsule-shaped water absorption bin, and absorbent cotton is installed in the inner cavity of the capsule-shaped water absorption bin.

[0011] Furthermore, the hinged joint, the hinged rod and the capsule-shaped water absorption chamber are preferably made of soft rubber material.

[0012] Furthermore, the rear end diameter of the expanded tube is smaller than the front end diameter, and the cross section of the expanded tube is elliptical.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In this utility model, the patient's teeth bite on the air bag in the middle of the two ring blocks. During the examination, the doctor can release part of the gas in the air bag by pinching the soft rubber air nozzle, so that the patient's upper and lower teeth are closer together, thereby preventing the patient's mouth from always remaining in a fixed open state and reducing the pressure in the mouth.

[0015] 2. The saliva secreted during the examination is absorbed by the absorbent cotton in the inner cavity of the capsule-shaped water absorption chamber. The doctor does not need to frequently use the extraction equipment to extract the saliva secreted in the patient's mouth, which reduces the doctor's operating pressure during the gastroscopy operation.

[0028] Example:

[0029] As attached Figure 1 To the attached Figure 4 The figure shows a multifunctional oral opening device for gastroscopy, comprising an expanding tube 1, a lip front plate 2 fixedly mounted on the front end of the expanding tube 1, an occlusal adjustment component 3 fixedly sleeved on the outer wall surface of one end of the expanding tube 1 close to the lip front plate 2, and a water absorption component 4 symmetrically mounted on the outer wall surface of the middle portion of the expanding tube 1;

[0030] The bite adjustment assembly 3 includes two annular blocks 301 fixedly sleeved on the outer wall of the flared tube 1. An air bag 302 is bonded to the middle of the two annular blocks 301. A soft rubber air nozzle 303 is installed on the front wall of the air bag 302. The air inlet end of the soft rubber air nozzle 303 extends through the front wall of the lip front plate 2.

[0031] The ring block 301 is preferably made of silicone;

[0032] On it, the teeth bite on the air bag 302 in the middle of the two ring blocks 301. During the examination, the doctor can release part of the gas in the air bag 302 by pinching the soft rubber air nozzle 303, so that the patient's upper and lower teeth are closer together and the pressure in the oral cavity is relieved. The ring block 301 is made of silicone material because the silicone material has a soft texture. When the teeth bite on the air bag 302, the contact between the ring block 301 and the gums is softer, avoiding gum injury.

[0033] As attached Figure 1 To the attached Figure 4 As shown, in some embodiments, the water absorption assembly 4 includes a hinged head 401 fixedly mounted on the middle of the outer wall of the flared tube 1, a hinged rod 402 is rotatably mounted on the hinged head 401, a capsule-shaped water absorption chamber 403 is fixedly mounted on the other end of the hinged rod 402, and water inlet holes 404 communicating with the inner cavity are evenly distributed on the capsule-shaped water absorption chamber 403, and absorbent cotton 405 is installed in the inner cavity of the capsule-shaped water absorption chamber 403;

[0034] The hinged joint 401, the hinged rod 402 and the capsule-shaped water absorption chamber 403 are preferably made of soft rubber material;

[0035] On top of it, the saliva secreted in the patient's mouth is absorbed by the absorbent cotton 405 in the inner cavity of the capsule-shaped water absorption chamber 403. The doctor does not need to frequently use the extraction equipment to extract the saliva secreted in the patient's mouth. The friction between the soft rubber material and the mouth is smaller, which reduces the foreign body sensation and discomfort in the patient's mouth. The soft rubber material used for the capsule-shaped water absorption chamber 403 is convenient for cooperating with the absorbent cotton 405 to expand after absorbing saliva.

[0036] As attached Figure 1 To the attached Figure 4 As shown, in some embodiments, the rear end diameter of the expanded tube 1 is smaller than the front end diameter, and the cross section of the expanded tube 1 is elliptical;

[0037] The rear end diameter of the expanded tube 1 is smaller than the front end diameter to reduce the pressure inside the patient's mouth and to facilitate the placement of the water absorption component 4. The cross-section of the expanded tube 1 is elliptical to adapt to the shape of the mouth.

[0038] The specific usage and function of this embodiment are as follows: after placing the expansion tube 1 into the patient's mouth, the patient's teeth are allowed to bite on the air bag 302 in the middle of the two annular blocks 301. During the examination, the doctor can release part of the gas in the air bag 302 by pinching the soft rubber air nozzle 303, so that the upper and lower teeth of the patient are brought closer together, thereby preventing the patient's mouth from being always in a fixed open state and reducing the pressure in the mouth;

[0039] The saliva secreted during the examination is absorbed by the absorbent cotton 405 in the inner cavity of the capsule-shaped water absorption chamber 403. The doctor does not need to frequently use the suction equipment to extract the saliva secreted in the patient's mouth, which reduces the doctor's operating pressure during the gastroscopy operation.

[0040] The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.
