Description

Respiratory tract pathogen protective cover for tracheotomy patient
Technical Field
The utility model relates to the technical field of medical care products, in particular to a respiratory tract pathogen protective cover for a tracheotomy patient.
Background
Tracheostomy tubes are used for adult patients requiring anesthesia, artificial ventilation or other assisted breathing, who, due to some disease cause, such as laryngeal tumors, require tracheotomies and then tracheostomy tubes in the neck, through which the gas does not pass either through the nasal or oral cavity. Referring to fig. 1, the tracheotomy tube comprises an outer cannula (1), fixation wings (2), an inner cannula (3) and a cuff (4).
At present, no protective cover specially used for tracheotomy patients exists in the market, and great potential safety hazards are brought to the lives of people and the contact persons of people. Because the tracheotomy tube worn by the patient is directly exposed outside and has no purification function of the nasopharynx part, if the patient directly inhales gas which is not filtered and purified, the risk that the patient is infected with other diseases is increased, the risk of the patient's own illness state is aggravated, and floating objects or mosquitoes in the air are easily inhaled by mistake, so that the patient is uncomfortable and even suffocated; meanwhile, if the gas exhaled by the patient carries pathogenic bacteria, the patient can also infect surrounding people, and cross infection is very easy to cause.
In clinic, the common mask is taken as a protective cover on the neck of a patient, but the following defects are found in the use process: the conventional mask is designed according to the facial contour of a human body, the mask has a good covering effect on the mouth and the nose of the human body, but the mask cannot be tightly combined with the neck of the tracheal cannula at the neck, and air easily passes through a gap between the mask and the skin, so that the filtering and protecting effect of the mask is poor; secondly, the conventional mask is soft in texture, but the tracheal cannula is of a tubular structure, so that when the mask is used for inhaling, a thin sheet of the mask is easily sucked, and the mask covers the mouth of the tracheal cannula, so that the gas exchange efficiency is reduced, the patient has difficulty in inhaling, and even the patient is suffocated seriously.
SUMMERY OF THE UTILITY MODEL
Aiming at the technical problem that no protective cover specially used for tracheotomy patients exists in the prior art, the utility model provides the respiratory tract pathogen protective cover for the tracheotomy patients.
The technical scheme adopted by the utility model is as follows: a respiratory tract pathogen protection casing for patient is cut to trachea, including the cover body and the fixed rope of setting on the cover body, the cover body includes by interior outer layer that has set gradually layer, filter layer and the water blocking layer that absorbs water, it is provided with the cavity to absorb water between layer and the filter layer, is provided with the support of fretwork in the cavity, absorbs water and is provided with the gas pocket that is used for installing the trachea and cuts the intubate on the layer, and the gas pocket extends to in the cavity. The protective cover is made of the material of the traditional mask, only the cavity is arranged between the water absorbing layer and the filter layer, the hollow support is arranged in the cavity, the support plays a role in supporting the cavity, and the air holes extend into the cavity. That is to say, the outer cannula of the tracheotomy cannula is inserted in the air hole, and the end part of the outer cannula can not touch the protective cover. On one hand, the air holes ensure the sealing performance of the protective cover and prevent air from entering the body of a patient from the gap of the protective cover; on the other hand, has had the supporting role of support frame, and the patient is breathing, inspiratory in-process, and the outer cannula tip of tracheotomy tube can not touch the protection casing, avoids the protection casing to be inhaled the flat outer cannula that leads to blockking up to guarantee unobstructed breathing, breathing in of patient, guarantee gas exchange's efficiency, avoid the patient to appear breathing the difficulty, the condition of suffocation even takes place. The protection casing plays the filtering action to the gas of circulation, has both played the guard action to patient itself, has also played the guard action to crowd on every side.
Furthermore, the inner wall of the air hole is provided with an elastic layer which has certain elasticity, so that the outer cannula of the tracheotomy tube is matched with the air hole more tightly, the sealing performance is enhanced, and the gas is prevented from passing through the gap between the outer cannula and the air hole.
Furthermore, the elastic layer is made of medical silica gel, and has the advantages of good elasticity, no toxicity, no odor, physiological inertia, biological aging resistance and the like.
Furthermore, the bracket is made of plastic, and has the advantages of high hardness, light weight, low price and the like.
Furthermore, the cross section of the support is arc-shaped, so that the protective cover can be well attached to the neck of a patient.
Furthermore, the fixing rope is an elastic band which has certain elasticity and can be suitable for the neck sizes of different people; meanwhile, the elastic band is wider, the contact area with the neck of a patient is large, and the pressure injury to the patient can be reduced.
Furthermore, the elastic band is provided with the contraction button, so that the size of the elastic band can be adjusted according to different people, and the patient can wear the elastic band more comfortably.
The utility model has the beneficial effects that:
1. the protective cover provided by the utility model has a filtering effect on the circulated gas, and not only has a protection effect on tracheotomy patients, but also has a protection effect on surrounding people.
2. The air hole ensures the sealing performance of the protective cover, and prevents air from entering the patient body from the gap of the protective cover; in addition, having had the supporting role of support frame, the patient is breathing, inspiratory in-process, and the outer cannula tip of tracheotomy intubate can not touch the protection casing, avoids the protection casing to be inhaled the flat outer cannula that leads to blockking up to guarantee unobstructed breathing, breathing in of patient, guarantee gas exchange's efficiency, avoid the patient to appear breathing the difficulty, the condition of suffocation even takes place.
3. The elastic layer has certain elasticity, so that the outer cannula of the tracheotomy tube is matched with the air holes more tightly, the sealing performance is enhanced, and the air is prevented from passing through the gap between the outer cannula and the air holes.
