Description

Technical Field

[0001] The utility model relates to the field of gastroscopic catheters, in particular to an anti-suffocation oral special-shaped gastroscopic catheter. Background Art

[0002] During gastroscopy and esophageal intubation, a catheter consisting of a bite tube and a cannula needs to be placed in the patient's mouth. The bite tube is for the patient to bite on to prevent the patient from biting the esophagus or gastroscope tube during intubation. The cannula provides a channel for gastroscope insertion and can also prevent the patient from closing their mouth due to discomfort and suffocating.

[0003] In the prior art, bite tubes are hard and made of hard plastic, which has strong strength and can support the patient's bite force. Since the cannula needs to be inserted into the patient's mouth to the larynx, it is soft and usually made of silicone material. The bite tube also has a baffle part that is placed on the outside of the patient and fits against the patient's lips when in use. When in use, the baffle part is tied with straps on both sides to assist in installation, so that the entire cannula can be stably supported on the patient's head.

[0004] However, the above-mentioned gastroscopic catheters in the prior art have certain limitations when used: 1. After the baffle part on the bite tube of the existing gastroscopic catheter is tied with a strap and the strap is fixed around the patient's head, the connection between the strap and the baffle part is relatively prominent, and it fits against the patient's cheek and causes strong discomfort; 2. In order to ensure a strong supporting effect, the bite tube part in the prior art is relatively hard, and when the patient bites, the teeth directly contact the bite tube and apply force to bite, which is likely to cause certain damage to the teeth, further reducing the wearing comfort. Utility Model Content

[0005] In order to make up for the deficiencies of the existing technical problems, the purpose of the present utility model is to provide an anti-suffocation oral special-shaped gastroscopic catheter that can block between the baffle portion and the patient's cheek, and form a barrier between the patient's teeth and the tube body to improve wearing comfort.

[0007] Disclosed is an anti-suffocation oral special-shaped gastroscopic catheter, comprising a bite tube, a sleeve inserted into the bite tube, a tracheal groove formed in the middle of the lower portion of the sleeve, a soft tracheal tube inserted into the tracheal groove, a joint inserted into the end of the soft tracheal tube away from the tracheal groove, symmetrical binding grooves formed on the bite tube, and a protective member sleeved on the outer side of the bite tube.

[0008] Preferably, the bite tube consists of a tube body and a baffle formed on one side of the tube body, and the two binding grooves are symmetrically formed on the baffle.

[0009] Preferably, the protective member is composed of a bite sleeve sleeved on the outside of the tube body and a spacer portion formed on a side of the bite sleeve close to the baffle portion, and the bite sleeve and the spacer portion are both made of silicone material.

[0010] Preferably, the sleeve is composed of a semicircular arc piece inserted into the inner side of the tube body and a limiting piece formed on one end of the semicircular arc piece close to the baffle piece. The tracheal groove is opened in the middle position of the semicircular arc piece. The end of the semicircular arc piece away from the limiting piece is set in a downward curved arc shape. The semicircular arc piece and the limiting piece are both made of silicone material.

[0011] Preferably, a nesting groove is provided on the inner wall of the tube body, and the semicircular arc piece is inserted into the nesting groove.

[0012] Preferably, reinforcing ribs are formed at equal intervals in the middle of one side surface of the depression of the semicircular arc piece, and the reinforcing ribs are integrally arranged with the semicircular arc piece.

[0013] Preferably, both ends of the semicircular arc portion away from the limiting portion are chamfered.

[0014] Compared with the prior art, the advantages of the present invention are as follows:

[0015] 1. By installing a protective piece on the outside of the bite tube, a septum is placed between the connection between the strap and the baffle and the patient's cheek when the catheter is worn, reducing the discomfort caused by the connection between the strap and the baffle. At the same time, the bite sleeve is placed between the patient's teeth and the bite tube, preventing the teeth from directly contacting the hard bite tube, alleviating the discomfort and greatly improving the patient's comfort when wearing the catheter.

[0016] 2. The reinforcement ribs provided improve the strength of the semicircular arc piece, thereby improving the bending and tearing resistance of the middle position of the concave part of the semicircular arc piece, thereby reducing the probability of damage to the tracheal groove.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] For example 1, please refer to Figures 1 to 6 This embodiment provides an anti-asphyxia oral special-shaped gastroscopic catheter, including a bite tube 1, which is composed of a tube body 101 and a baffle portion 102 formed on one side of the tube body 101, two binding grooves 103 are symmetrically formed on the baffle portion 102, and a nesting groove 1011 is formed on the inner wall of the tube body 101;

[0027] When wearing the device, the strap is passed through the strap slot 103, the strap is wrapped around the patient's head, and the tube body 101 of the bite tube 1 is inserted into the patient's mouth, the bite tube 1 is fixed on the patient's head, and the baffle portion 102 is attached to the patient's lips;

[0028] The sleeve 2 is inserted into the bite tube 1. The sleeve 2 consists of a semicircular piece 201 inserted into the nesting groove 1011 and a limiting piece 202 formed at one end of the semicircular piece 201 close to the blocking piece 102. The tracheal groove 203 is opened in the middle of the semicircular piece 201.

[0029] After the tube body 101 is put on, intubation can be carried out. The intubation tube device, i.e., the gastroscope tube, is inserted into the patient's oral cavity between the limiting piece 202 and the semicircular piece 201. The semicircular piece 201 plays a guiding role, and the nesting groove 1011 can limit the position of the semicircular piece 201 inside the tube body 101.

[0030] One end of the semicircular arc portion 201 away from the limiting portion 202 is in a downwardly curved arc shape. The semicircular arc portion 201 and the limiting portion 202 are both made of silicone material. Both ends of the semicircular arc portion 201 away from the limiting portion 202 are rounded. The arc shape of the semicircular arc portion 201 conforms to the ergonomic design and can better fit the patient's oral cavity. The use of silicone material can reduce the foreign body sensation in the patient's oral cavity and avoid causing harm to the patient.

[0031] A soft trachea 3 is inserted into the tracheal groove 203, and a connector 4 is inserted at one end of the soft trachea 3 away from the tracheal groove 203. After intubation, the connector 4 can be connected to an end-tidal carbon dioxide detector and an oxygen source.

[0032] The connector 4 includes an oxygen interface 41 connected to the oxygen source and a detection interface 42 connected to the detection end of the end-tidal carbon dioxide detector. When in use, the oxygen delivered by the oxygen source enters the soft trachea 3 through the oxygen interface 41 and finally enters the tracheal groove 203;

[0033] The outer side of the bite tube 1 is provided with a protective member 5; the protective member 5 is composed of a bite sleeve 501 which is sleeved on the outer side of the tube body 101 and a spacer portion 502 formed on the side of the bite sleeve 501 close to the baffle portion 102. The bite sleeve 501 and the spacer portion 502 are both made of silicone material;

[0034] After the patient wears the entire device, the bite sleeve 501 forms a barrier between the patient's teeth and the tube body 101, preventing the patient's teeth from directly contacting the harder tube body 101, thereby reducing the discomfort of the patient's teeth, and the pad portion 502 forms a barrier between the patient's cheek and the baffle portion 102, thereby preventing the connection between the strap and the baffle portion 102 from directly fitting the patient, further reducing the discomfort of wearing and improving the comfort of use.

[0035] The bite sleeve 501 and the spacer portion 502 are of an integrated structure, which saves production costs and can be installed with the bite tube 1 in one assembly.

[0036] For example 2, please refer to Figure 7 This embodiment provides a further technical solution based on the first embodiment. Reinforcing ribs 6 are formed at equal intervals in the middle of one side of the depression of the semicircular arc piece 201. The reinforcing ribs 6 and the semicircular arc piece 201 are integrally arranged, so that the bending and tearing resistance of the middle position of the depression of the semicircular arc piece 201 is improved, thereby reducing the probability of damage to the tracheal groove 203.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
