Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field, concretely relates to a tracheal flap. BACKGROUND

[0002] The state of the tracheal flap is related to the stenosis of the bronchus. When the bronchus is stenotic, the flap will be in an open state to ensure that the airflow can enter the lungs. When the bronchus is completely blocked, the flap will be in a closed state, thereby forming a one-way valve function to prevent the airflow from being discharged, resulting in persistent lung obstruction. Common types of flaps include airway stenosis and bronchospasm. Airway stenosis can be caused by airway inflammation, tumors, foreign bodies, etc., while bronchospasm can be caused by neuromuscular diseases, allergic reactions, etc. In the flap state, the patient will have persistent coughing, wheezing, chest tightness, and other symptoms, and in severe cases, it can even lead to suffocation. Treatment methods usually include drug therapy and surgical treatment. Drug therapy mainly uses anti-inflammatory, anti-asthma, and other drugs to relieve symptoms, while surgical treatment includes dilation, plastic surgery, etc.

[0003] The prior art CN115531038A discloses a one-way flap for bronchus, but the flap does not have a developing structure. If it is desired to observe the flap under X-rays, an additional developing operation is required, which is relatively cumbersome and complex. In order to solve the above problems existing in the prior art, the utility model is proposed, which has a developing structure and can better observe the position of the flap after being implanted into the human body.

The outer wall of the main support is in contact with the inner wall of the bronchus, and the one-way valve is arranged outside the inner cavity of the main support.

[0005] In the utility model, as one of the implementation schemes, the main support 1 is a hollow cylindrical structure, one end of the main support is integrally connected with the one-way valve, and the other end of the main support 1 is integrally connected with the developing ring.

[0006] In the utility model, as one of the implementation schemes, the outer wall of the main support is uniformly or non-uniformly provided with a plurality of anti-slip protrusions. Preferably, the number of circles of the anti-slip protrusions is set to 2 circles, and the number of the anti-slip protrusions is set to 12.

[0007] In the utility model, the one-way valve is a duckbill structure, the tracheal flap discharges the gas in the targeted position through the opening and closing of the one-way valve, and realizes lung volume reduction.

[0008] The developing ring and the main body support are integrally formed by two injection molding processes.

[0009] In the utility model, as one of the implementation schemes, the developing ring 2 is added with barium sulfate, and is formed by pressing silicon rubber raw material with 30% barium sulfate.

[0010] In the utility model, the flap in the bronchus is integrally formed by the long-term implantable silicon rubber.

[0011] In the utility model, as one of the implementation schemes, after the flap in the bronchus is implanted into the human body, the specific position can be displayed under the X-ray through the developing ring.

[0012] In the utility model, when the one-way flap is usually used, the bronchial one-way flap support is first put into the bronchus of the target lung lobe segment through the conventional bronchoscope, the bronchial one-way flap support is one-way conductive, is closed when the patient inhales, is opened when the patient exhales, simultaneously drains the secretions of the distal end of the airway, gradually makes the residual gas in the distal end lung lobe segment of the bronchial one-way flap support discharge, the secretions flow out, makes the target lung lobe segment gradually fibrosis, the healthy lung gradually expands and plays a compensatory role, restores the lung function of the patient, and cures the patient.

[0013] Compared with the prior art, the flap in the bronchus has the following beneficial effects:

[0014] 1. The whole flap support of the utility model is integrally formed by the silicon rubber. The 2 circles of 12 anti-skid convex points 3 are uniformly distributed on the flap, ensure that the outer wall of the bronchial flap can be in close contact with the inner wall of the bronchus, increase the friction, and can better prevent the displacement of the flap.

[0015] 2. The one-way valve 4 of the utility model is of a duckbill type structure, and the duckbill is on the outside, so that the opening of the duckbill can be larger, and has better secretion discharge capacity.

[0016] 3. The utility model adds the developing structure, and the position of the flap can be better observed after being implanted into the human body. BRIEF DESCRIPTION OF DRAWINGS

[0022] like Figure 1 As shown, in this utility model, the bronchial valve includes a main support 1, a imaging ring 2, anti-slip protrusions 3, and a one-way valve 4. The main support 1 is a hollow cylindrical structure, and the outer wall of the main support 1 is in contact with the inner wall of the bronchus.

[0023] The one-way valve 4 is disposed outside the inner cavity of the main support 1. The one-way valve 4 can be partially or entirely disposed within the inner cavity of the main support 1; for example, the one-way valve 4 may be entirely enclosed by the main support 1, or a portion of the one-way valve 4 may be disposed within the inner cavity of the main support 1. As a preferred embodiment, in this case, the one-way valve 4 is entirely located outside the inner cavity of the main support 1.
