Description

Autogenous cutting type high flow pipeline

Technical Field

The application relates to medical equipment, in particular to an autogenous cutting type high-flow pipeline.

Background

The autogenous high-flow oxygen Therapy (THFO) is mainly suitable for patients with serious illness and hypoxia, and the patients need high-flow oxygen inhalation to relieve the hypoxia due to serious hypoxia. The aerotomy high flow oxygen therapy can provide accurate inhaled oxygen concentration and optimal airway humidification, which helps to improve the anoxic condition of the patient. 2. When rescuing, the patient with craniocerebral injury usually needs tracheotomy, but the operation is easy to damage the epithelial cell function of the respiratory tract, which causes pathological changes of the airway tissue and increases the degree of hypoxia. Reasonable airway humidification is particularly important for patients of this type, and can sufficiently humidify the airways, dilute sputum, reduce the viscosity of the sputum, maintain the ciliated movement and clearance functions of the airways, avoid airway blockage and promote recovery of the patients. 3. For patients relying on mechanical ventilation for a long time, the air-cutting type high-flow oxygen therapy can be used as an auxiliary means in the machine removing process to help the patients to gradually adapt to spontaneous breathing. 4. The aerotomy high flow oxygen therapy can also be used as a family oxygen therapy mode for the chronic respiratory failure patients, so that the life quality of the patients is improved.

The aero-cut high flow oxygen therapy is implemented by an aero-cut high flow line.

The structure of the current autogenous high-flow pipeline is shown in fig. 1-3, and comprises a Y-shaped pipe 10 and a shielding shell 20, wherein the first end of the Y-shaped pipe is used for being connected to a tracheotomy sleeve of a patient, the second end of the Y-shaped pipe is connected with a high-flow oxygen source through a threaded hose, and the shielding shell is integrally arranged at the third end and used for blocking sputum sprayed by the patient during cough.

The existing autogenous cutting type high-flow pipeline has the defects that 1, the connection between the shielding shell and the Y-shaped pipe cannot be disassembled, so that the patient can not conveniently and timely replace and clean the sputum-discharged sputum, only the whole pipeline can be replaced each time, the cost is too high, consumables are wasted, and family members are difficult to accept. 2. After the patient expects the sputum, the sputum can spray on the patient or on the clothes, leads to the sputum of patient to be everywhere, and is neither pleasing to the eye nor sanitary, can cause the infection easily, still can increase medical personnel's work, need the occasional sputum of expectoration of wiping patient and wash the fender cap. 3. The shielding shell is made of blue plastic shells, so that the property and the quantity of sputum of a patient can not be well observed, and the effect of observing the condition of the patient is not achieved in clinical work, so that the use of the clinical work is not facilitated.

Disclosure of utility model

In view of the above problems, the present application aims to provide an autogenous high flow rate pipeline which can attach sputum ejected when a subject coughs and can conveniently observe the sputum.

The application relates to an autogenous cutting type high-flow pipeline which comprises a Y-shaped pipe, wherein a first end of the Y-shaped pipe is used for being connected to a tracheostomy tube of a patient, and a second end of the Y-shaped pipe is connected with a high-flow oxygen source through a threaded hose;

the third end of the Y-shaped pipe can be detachably inserted with a sputum-blocking cap;

The sputum blocking cap comprises a tube body and a blocking piece, wherein the tube body and the blocking piece are made of transparent plastic, the first end of the tube body is inserted into the third end of the Y-shaped tube, the blocking piece is connected to the second end of the tube body through at least two connecting rods, a preset interval is formed between the blocking piece and the second end of the tube body, a plurality of elastic naps are fixedly formed on the inner peripheral surface of the tube body and used for blocking and attaching sputum ejected by a subject when the subject cough, and the naps are spirally distributed along the inner peripheral surface of the tube body.

Preferably, the blocking piece completely covers the second end of the tube body in the axial direction of the tube body.

Preferably, the edge of the flap is turned in the direction of the second end of the tube.

The autogenous cutting type high-flow pipeline can be detachably arranged on the Y-shaped pipe, and is convenient to replace or clean; in the autogenous cutting type high-flow pipeline, the Y-shaped pipe and the sputum blocking cap form transparent, so that the property and quality of sputum can be conveniently observed when the sputum is adhered to the Y-shaped pipe and the sputum blocking cap.

Detailed Description

The autogenous high flow line of the present application will be described in detail with reference to the accompanying drawings.

The inventive tracheostomy high flow line comprises a Y-tube 10, the first end of the Y-tube 10 being adapted to be connected to a tracheostomy tube of a patient and the second end being connected to a high flow oxygen source by a threaded hose. This is the same as in the prior art.

In the application, the third end of the Y-shaped tube 10 is detachably connected with a sputum-blocking cap 30.

The sputum-blocking cap 30 comprises a tube body 31 and a baffle plate 32, wherein the tube body 31 and the baffle plate 32 are made of transparent plastic, a first end of the tube body 31 is inserted into a third end of the Y-shaped tube 10, the baffle plate 32 is connected to a second end of the tube body 31 through at least two connecting rods 34, a preset interval is formed between the baffle plate and the second end of the tube body 31, a plurality of elastic fine hairs 34 similar to bristles of a toothbrush are fixedly formed on the inner peripheral surface of the tube body 31, and the arrangement is sparse, so that smooth respiration of a subject is ensured. The nap may also be a transparent fiber. The naps 34 may be inclined to block and adhere sputum ejected from a subject when coughing, the root of each nap is close to the first end of the tube and the head is close to the second end of the tube, the plurality of naps 34 are spirally distributed along the inner circumferential surface of the tube 31, so that the naps do not distribute the cross section of the whole tube but cover only a predetermined angle, e.g., 30 degrees, of the cross section in a cross section perpendicular to the axial direction of the tube 31, thus ensuring a sufficient air circulation space in each cross section, but the plurality of cross sections are staggered in the circumferential direction at an angle, so that the whole tube is covered with the naps in the axial direction, thereby allowing excellent adhesion or adherence of sputum.

The blocking piece 31 completely covers the second end of the tube body 31 in the axial direction of the tube body 31, so that if sputum escapes from the tube body, the sputum can be blocked and adhered by the blocking piece. The edge of the blocking piece 32 is folded in the direction of the second end of the tube 31.

When the tracheostomy tube is used, the tracheostomy high-flow pipeline is arranged on the tracheostomy tube, sputum is blocked and adhered by the fine hair layer in the sputum blocking tube when a patient coughs, the sputum is not easy to spray outside, and the sputum adhered in the tube can be conveniently observed due to the transparent plastic of the tube body and the baffle. Because the air-cutting type high-flow pipeline is detachably arranged on the tracheotomy sleeve, the air-cutting type high-flow pipeline can be taken off at any time and washed by clean water, and can also be directly replaced by a new air-cutting type high-flow pipeline.
