Description

A catheter holder for nasal intubation

technical field

The invention relates to a medical auxiliary device, in particular to a catheter fixer for nasal intubation.

Background technique

In the process of anesthesia or first aid for critically ill patients, in order to ensure effective ventilation and unobstructed airway, tracheal intubation technology is often used to establish an artificial airway for mechanical ventilation of the patient. At present, the tracheal intubation is generally fixed with simple silk tape, and if necessary, a non-elastic cloth is used to wrap the tracheal intubation and fixator and wrap it around the head. The above-mentioned fixation method is cumbersome to operate, the reliability of fixation is poor, and the adhesive tape is easy to fall off after being damp, thus causing the catheter to slip, which will endanger the life of the patient if it is not discovered in time; meanwhile, some patients are allergic to the adhesive tape and have poor comfort.

In order to overcome the above-mentioned deficiencies, there are various fixers applied to nasal intubation catheters in the prior art. For example, the Chinese utility model patent with application number 201220114636.5 discloses a nasal cavity and endotracheal intubation fixer, which includes segmented connections The fixed wing (3), the inner surface of the fixed wing (3) fits the nose alar portion and the facial structure, and the fixed wing (3) of each segment is connected by the fixed wing movable connection part (1), so that each The angle between the planes of the segmented fixed wings (3) can be adjusted, fixed belts (5) are provided on both sides and the top of the fixed wings (3), the middle part of the fixed wings (3) is provided with an opening, and the spiral locking structure (7) Fixed on the fixed wing (3), the front end of the helical locking structure (7) protrudes into the opening and is connected with the helical locking structure washer (6) provided in the opening. This kind of fixator fixes the trachea through the three-point fixation of the fixed wings (both sides of the head and maxillofacial region). The fixed belt will not only increase people's discomfort, but also cause the trachea to warp upwards due to too strong binding, and the connection interface between the trachea and the patient's nose will move, which cannot ensure the smoothness of the trachea.

Contents of the invention

In view of the above-mentioned deficiencies, the technical problem to be solved by the present invention is to provide a catheter holder for nasal cannula with simple structure. Human comfort.

In order to solve the above problems, the present invention is realized through the following technical solutions:

A catheter holder for nasal intubation, comprising a catheter clip and two straps for fixing the catheter clip, the catheter clip includes a housing and a through hole for catheter insertion, the through hole runs through the housing and is The side part of the through hole is provided with a channel communicating with the through hole as a whole, and a fastener for fixing the air pipe is provided on one side of the channel and on the casing; the straps are respectively connected to both sides of the bottom end of the casing, One end of the through hole is provided with a nasal interface, and the nasal interface is on the same plane as the strap.

In the above solution, the channel extends linearly along one side wall of the through hole to the outside of the shell wall, and the opening position of the channel is located on the corresponding shell between the two straps.

In the above solution, the fastener may include a telescopic screw and a gasket used in conjunction with the telescopic screw, the telescopic screw is provided with threads, and the front end of the telescopic screw extends into the channel.

In the above solution, the nasal cavity interface may be a hollow ring formed by extending 0.4-0.6 cm outward along the end wall of the through hole. When in use, the nasal cavity interface is inserted into the nostril of the patient, and the tracheal intubation tube is inserted into the through hole to be connected with the nasal cavity interface, so as to prevent the connection between the tracheal intubation tube and the patient's nostril from moving.

In the above scheme, in order to avoid the squeeze of the strap to the skin of the human body and improve the comfort of the human body, a sponge pad is provided at the extended position of the connection between the strap and the housing, and the sponge pad is in contact with the body when in use. skin-to-skin contact.

In the above solution, for the convenience of use, adhesive tapes are provided at both ends of the strap.

The beneficial effects of the present invention are:

1. The present invention realizes the fixing effect on the catheter intubation through the provided through holes, passages and telescopic screw rods, combined with the use of straps, with simple structure and convenient operation;

2. Through the nasal cavity interface provided at the end of the through hole, not only can the installation of the catheter clamp be more stable, but also make the connection between the catheter intubation and the patient's nose more firm, and it will not move, making it safer to use;

3. The sponge pad provided on the strap can effectively improve the patient's comfort.

detailed description

The present invention will be further explained below in conjunction with specific embodiments and drawings, but it is not intended to limit the present invention.

As shown in Figure 1, a catheter holder for nasal intubation includes a catheter clip 1 and two straps 2 for fixing the catheter clip, and the catheter clip 1 includes a housing 4 and a through hole 3 for catheter insertion The through hole 3 runs through the housing 4 and a channel 9 communicating with the through hole 3 is provided on the side of the through hole 3. The channel 9 is specifically along a straight line on one side wall of the through hole 3 It extends to the space formed outside the wall of the casing 4 , and the channel 9 is opened on the corresponding casing 4 between the two straps 2 . On one side of the channel 9, on the housing 4, there are fasteners for fixing the air tube. In this embodiment, the fastener includes a telescopic screw 5 and a spacer used in conjunction with the telescopic screw 5 , the telescopic screw 5 is provided with threads, and the front end of the telescopic screw 5 extends into the channel 9 . The straps 2 are respectively connected to both sides of the bottom end of the housing 4 , and a nasal cavity interface 7 is provided at one end of the through hole 3 , and the nasal cavity interface 7 is on the same plane as the straps 2 .

As shown in FIG. 2 , a sponge pad 8 is provided at the extended position of the connection between the strap 2 and the housing 4 , and the sponge pad 8 is in contact with the skin of the human body during use. In order to improve the convenience of using the strap 2, an adhesive tape 6 is provided at both ends of the strap 2. Of course, it is not necessary to set the adhesive tape 6, and the binding tape 2 can be set as a cloth strip, which can be directly knotted and bound during use. The nasal interface 7 is a hollow ring formed by extending 0.4-0.6 cm outward along the end wall of the through hole 3 . Certainly, the nasal cavity interface 7 may specifically be a hollow semi-circular ring movably installed at the end of the through hole 3 . The caliber of the nasal cavity interface 7 is smaller than the nostrils of the human body, and the caliber of the through hole 3 is larger than that of the common specification tracheal tube.

When the present invention is in use, after the endotracheal tube is inserted, the endotracheal tube is inserted into the through hole 3 and connected to the nasal cavity interface 7, then the nasal cavity interface 7 is inserted into the patient's nasal cavity, and the tube is fixed by tightening the telescopic screw rod 5, and then Wrap the strap 2 around the back of the head, adjust the tightness, and then fix the entire catheter clip 1 with the adhesive tape 6, which completes the installation of the endotracheal tube.

The above is only to illustrate the implementation of the present invention, and is not intended to limit the present invention. For those skilled in the art, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be Included within the protection scope of the present invention.
