Description

Anti-bite type ventilation catheter for cardiovascular internal medicine nursing

Technical Field

The invention belongs to the technical field of nursing of cardiovascular medicine, and particularly relates to a bite-preventing type ventilation catheter for nursing of the cardiovascular medicine.

Background

Cardiovascular diseases are common heart problems in clinic, the common cardiovascular diseases comprise angina pectoris, hypertension, arrhythmia, sudden death, heart failure, myocardial infarction and other diseases, cardiovascular patients often have symptoms of dyspnea, and in nursing emergency treatment, the patients need to be given an open airway, put an oropharyngeal airway and suck phlegm and oxygen or take measures such as phrenic abdominal impact and extrathoracic heart compression, so that conditions are provided for life support of the patients, and the success rate of nursing and emergency treatment is improved.

In the process of nursing and first-aid treatment of patients, patients may bite themselves or bite the airway tube due to convulsion and the like, which causes inconvenience to rescue work, therefore, the airway tube is provided with a bite block to protect the patients and the airway tube, but the airway tube used at present is made of plastic which is already formed and hard, when the morbidity of the patients is serious and the bite force is great, the airway tube which is possibly bitten and deformed or even bites the plastic is still used, which is not safe and reliable, in addition, because the airway tube is fixedly formed, but patients of different ages, such as children and adults, have different sizes of oropharyngeal passages, the airway tube with fixed shape can stimulate the oropharynx of the patients, easily cause nausea and vomiting, have inhalation risks or cause laryngeal spasm, cause negative stimulation or even secondary injury, bringing adverse effects to the nursing first aid of the patient.

In view of the above, research and improvement are made to solve the existing structure and defects, and an anti-bite type ventilation catheter for nursing in the cardiovascular department is provided, so as to achieve the purpose of higher practical value.

Disclosure of Invention

In order to solve the technical problems, the invention provides a bite-preventing type airway for nursing in the cardiovascular department, which aims to solve the problems that the general airway is insufficient in safety, fixed in shape and easy to stimulate patients.

The invention relates to a purpose and an effect of a bite-preventing type ventilation catheter for nursing in cardiovascular internal medicine, which are achieved by the following specific technical means:

the utility model provides a cardiovascular internal medicine nursing is with preventing stinging wound type pipe of ventilating, including the hard pipe, the outside of hard pipe is provided with the baffle, the outside of hard pipe and the left side movable mounting who is located the baffle have the protection to fill up, the internally mounted of hard pipe has the fagging, the inside of hard pipe and the outside activity that is located the fagging are pegged graft and are had soft pipe, the change has been cup jointed in the outside of hard pipe and the right side activity that is located the baffle, the top and the bottom of fagging all install the magnetic column through the sliding seat, the inside of hard pipe just is located movable mounting between change and the magnetic column has the chain belt, be provided with magnetic path one and magnetic path two corresponding with the magnetic column on the inner wall of chain belt, connect through the gear assembly meshing between change and the chain belt, one side that the protection was filled up and is close to soft pipe is connected with the slider through the rope, be.

Further, the top and the bottom of fagging all are the arc form, and the draw-in groove that corresponds with the fagging is seted up to the inside of hard pipe for the fagging can be fixed in the inside of hard pipe, and the cross section of fagging is the mouth shape, is convenient for ventilate.

Furthermore, a positioning assembly is arranged on the rotating ring, so that the rotating ring can be fixedly clamped on the hard pipe after rotating.

Furthermore, teeth matched with the gear assembly are arranged on the outer wall of the chain belt.

Furthermore, teeth matched with the gear assembly are arranged on the inner wall of the rotating ring.

Furthermore, the magnetism of one side of the first magnetic block and one side of the second magnetic block, which are close to the magnetic column, are opposite.

Furthermore, the inside of hard pipe is seted up the spout that corresponds with the slider, and the left side of spout is provided with the blend stop for the slider can remove about, thereby drives the left side of protection pad and draws in the expansion.

Advantageous effects

Compared with the prior art, the invention has the following beneficial effects:

1. the hard tube is inserted into the mouth of a patient, the rotating ring is rotated, the chain belt is driven to rotate through the gear assembly, the first magnetic block is aligned with the magnetic column, the magnetism between the first magnetic block and the magnetic column is the same, the magnetic column is contracted inwards under the action of repulsive force, the soft catheter is convenient to pull, the cylindrical magnetic column can further reduce the resistance when the soft catheter is pulled, and the operation is convenient; after inserting the soft pipe suitable length, the gyration swivel, at this moment, the whole initial condition that returns of device, the protection pad outwards expands, withstands patient's tooth, and magnetic path two aligns with the magnetic column for the magnetic column outwards removes and withstands soft pipe, avoids soft pipe dislocation slippage.

2. Through set up the wedge on the change, when rotatory on the change, the wedge promotes the slider and moves right, and the slider passes through the inside shrink in left side of rope pulling protection pad, forms a chamfer step, conveniently inserts the hard pipe in patient's mouth, has avoided the patient because the tooth interlock is too tight, and medical personnel are less to the open angle of patient's mouth, leads to the difficult male phenomenon of pipe.

3. The hard tube is arranged on the outer side of the soft catheter, so that the situation that the soft catheter is occluded and deformed to influence the ventilation effect due to the fact that the patient directly bites the soft catheter by teeth is avoided.

4. Through setting up protection pad and pressure spring, can protect patient's tooth, the pressure spring still plays the supplementary effect of strutting patient's mouth simultaneously.

5. Move and fix a position soft pipe through setting up magnetic column and magnetic path, can change the length that soft pipe inserted in patient's oropharynx, the crowd's oropharynx passageway size of having solved different age brackets is different, and the problem that the pipe of ventilating of fixed size caused stimulation to patient's oropharynx easily.

6. Through setting up the fagging, the top and the bottom of fagging are the arc form, and the fagging is hollow mouth shape, and the fagging still does not influence normal ventilation effect when fixing soft pipe, and it is more convenient to use.
