Abstract

The utility model discloses a plastic trachea catheter with a bag and belongs to the technical field of the medical instruments. The plastic trachea catheter with the bag consists of a plastic catheter (1), a plastic connecting tube (2), a plastic film cuff (3) and plastic airway parts (4). The plastic airway parts (4) include a retaining valve (4-1), which is arranged at the end of an air infusing tube (4-1-1), an elastic spring leaf (4-1-2) and an air inlet tube (4-1-3), which is mounted at the outer circle of the end of the air infusing tube (4-1-1). The utility model has the characteristics of simple structure, quite low manufacturing cost etc. and is a quite ideal trachea catheter with the bag at present.

Description

Plastic tape capsule endotracheal tube

Technical field

This utility model belongs to technical field of medical instruments, be specifically related to a kind of patient of being applicable to and accept that respiratory organ breathes, and it is got involved end and gets involved endotracheal plastic tape capsule endotracheal tube.

Background technology

Existing traditional endotracheal tube is metallic article, and is reusable medical apparatus and instruments.This undoubtedly metal endotracheal tube, not only patient's use feeling is poor, and causes cross infection extremely easily, and damages to the patient.And in recent years, this endotracheal tube of city's confession, change the metallic article that is repeatedly used before, and be disposable plastic, this obviously is a significantly progress, but with regard to its structure, check valve more complicated (seeing also accompanying drawing 1) still particularly, and its manufacturing cost is also higher relatively.

The purpose of this utility model is to provide a kind of relatively simple for structure, and the disposable plastic tape capsule endotracheal tube that cost is relatively low is to overcome the deficiency of prior art.

Realize that the technical scheme that the purpose of this utility model is taked is, it still has plastic catheter, plastics adapter, plastic film sleeve capsule and plastics airway assembly, and it is circular-arc that said plastic catheter is single-curved surface, plastics are taken over plastic catheter and are the tight fit binding, the plastic film sleeve capsule is sleeved on the intervention end of plastic catheter, and is sealing with plastic catheter and links, in the plastic bushing tube wall and along its length direction, be provided with gas port, and this gas port and plastic film sleeve capsule connect; And said plastics airway assembly shows that by check valve, gas storage bag and airway are formed, and airway and be located at the interior gas port of plastic catheter tube wall and be connected.And said check valve, it is the end in air injection pipe, installing elastic spring, and this spring leaf covers the center through hole of air injection pipe, and show with gas storage and then to be sleeved on the air inlet pipe that bag fuses and connects each other on the cylindrical of the said end of air injection pipe.

When using this utility model, back down elastic spring by the syringe needle front end, pushing syringe push rod again, and inject air.The air that is injected shows bag, airway and gas port via gas storage, enters the plastic film sleeve capsule then, and makes the plastic film sleeve capsule erect, and blocks person's windpipe.And, then be present in the air that gas storage shows that bag is interior with certain malleation when artificial gas injection termination, and react on elastic spring, and make elastic spring block the air injection pipe center through hole, leak thereby stopped up air.By the connection of plastics adapter, subsidize breathing even if carry out machinery to the patient with the respiratory organ pipeline.

The monitoring of intervention person's windpipe of the present utility model is by being located at the X-ray development line on the plastic catheter sidewall, realizing under the demonstration of X-ray machine display screen is instructed.Certainly, having under the physician guidance of clinical experience, can do get involved monitoring without the X-ray line that develops.

The included plastic catheter of this utility model is inserted the degree of depth of person's windpipe, is to realize by insertion depth sign set on its tube wall.

The pipeline of the plastic catheter that this utility model is included exhales, air-breathing further unobstructed, be end by the intervention end of plastic catheter, be provided with the inclined-plane and, be provided with through hole and realize by on the sidewall of the intervention end of plastic catheter.

After the technical solution of the utility model was implemented, the structure that it had is check valve relatively simple for structure especially, and characteristics such as manufacturing cost is relatively low are conspicuous.

Description of drawings

Below pass through the description of contrast drawings and Examples, will be more clear to the technical solution of the utility model and the purpose that will realize thereof.Identical in the accompanying drawings parts, with identical label mark, in these accompanying drawings:

Fig. 1 is the check valve cutaway view of prior art;

Fig. 2 is for master of the present utility model looks sketch map;

Fig. 3 is the A-A cutaway view of Fig. 1;

Fig. 4 is the structural representation of the included check valve of this utility model;

Fig. 5 is the front view of the elastic spring of the included check valve of this utility model.

The specific embodiment

See also accompanying drawing 2 and 3, this utility model is made up of plastic catheter 1, plastics adapter 2, plastic film sleeve capsule 3 and plastics airway assembly 4, and that said plastic bushing 1 is single-curved surface is circular-arc, plastics adapter 2 is tight fit with plastic catheter 1 and links, plastic film sleeve capsule 3, be sleeved on the intervention end of plastic catheter 1, and with plastic catheter 1 both through gluing and be sealing and link.In the tube wall of plastic catheter 1 and along its length direction, be provided with gas port 1-1, and this gas port 1-1 and plastic film sleeve capsule 3 connect; And said plastics airway assembly 4 shows that by check valve 4-1, gas storage bag 4-2 and airway 4-3 are formed, and airway 4-3 is connected with the gas port 1-1 that is located in plastic bushing 1 tube wall.And said check valve 4-1, it is the end at air injection pipe 4-1-1, adopt the processing technology of injection moulding inserts, be equiped with elastic spring 4-1-2, and this elastic spring 4-1-2 covers the center through hole of air injection pipe 4-1-1, and shows the air inlet pipe 4-1-3 that bag 4-2 fuses and connects each other with gas storage, then be sleeved on the cylindrical of the said end of air injection pipe 4-1-1, and with fluid sealant strict seal (please join and read attached Figure 4 and 5).Under the condition of necessity, can be at elastic spring 4-1-2, on the conflict face of air injection pipe 4-1-1, add flexible washer, perhaps add the column plug that mates sealing with air injection pipe 4-1-1 center through hole mutually, with its ability of avoiding the internal memory air to leak of further enhancing.On the sidewall of plastic bushing 1, be provided with and insert person's windpipe depth mark 5 and mainly by X-ray development line 6 that bismuth subcarbonate constituted.End at the intervention end of plastic catheter 1 is provided with inclined-plane 1-3; On the sidewall of the intervention end of plastic catheter 1, be provided with through hole 1-2, thereby enlarged of the present utility modelly exhale, the area of air intake passage mouth, avoided the generation of stopping state effectively.

Its included elastic spring 4-1-2 of this utility model adopts the thick phosphorus bronze sheet of 0.1mm, makes through technologies such as dashing, cut.Other is taken over 2 except that plastics and adopts the polypropylene moulding, is the medical polyvinyl moulding.
