Abstract
A check valve for functional lung excision consists of a cylindrical valve. Two hinged semi-circular movable blades are arranged in the valve, and the movable blades come into seal contact and are connected with a seal boss on the inner edge of the valve. A clamp fixing shaft is arranged at the upper parts of the movable blades. At least one anti-fall support is fixedly connected with the outer edge of the valve, the connection part of the anti-fall support with the valve outer edge is arc-shaped, and the other end of the anti-fall support is in a ratchet shape. The clamp fixing shaft is clamped by operators during operation, the check valve is put in under the observation of a fiber bronchoscope, and the movable blades are automatically closed to make air flow in one direction in the breathing process. As little as possible external air enters the far end, air, necrotic tissue and inflammatory secretion at the far end are discharged out of bodies with breathing, and sterile atelectasis treatment purposes are achieved. The anti-fall support makes the check valve difficult to fall. The utility model has the advantages of simple structure, easy processing and manufacture, low cost, simple clinic operation, convenient installation and use, easy grasp, good clinic effect, little fall possibility, etc.
Description
Technical field
This utility model relates to the improvement of medical apparatus and instruments structure, is a kind of functional pneumonectomy check valve specifically, belongs to the medical valve technology field that is particularly suitable for.
Background technology
Functional pneumonectomy be expectation by to the lung tissue (focal emphysema) that is confined to a certain leaf or section by drug blockage, mechanical close or insert method such as check valve, make this part lung tissue not have ventilatory function, thereby occur that this lung tissue segment withers, focal fibrosis and pulmonary atelectasis, venting QI-blood flow is distributed again, form the aseptic pulmonary atelectasis, reach the purpose of functional excision, avoid operation to bring huge misery to the patient.Wherein because check valve can shrink and modes such as expand, cough, pant by the thorax by the eupnea process, slough that inside may be occurred and the eliminating of rheuminess thing are external and become the focus of research.
At present, the check valve that uses mainly contains umbrella shape lobe (IBV), duckbill lobe (EBV), Tricuspid valve type etc. both at home and abroad, does not also have data to show that the valve of which kind of type has bigger advantage in the emphysema treatment.And have because complex structure, manufacturing cost height, no fixed support, reason such as come off easily, limited and clinically used and promote.
The utility model content
The purpose of this utility model is at above-mentioned deficiency, provide a kind of simple in structure, processing and fabricating is easy, cost is low, clinical manipulation is simple, easy to install, easy grasp, clinical effectiveness are good, the functional pneumonectomy check valve of difficult drop-off.
The technical scheme that realizes this utility model purpose is:
This functional pneumonectomy check valve is made of cylindric valve body, and characteristics are to be provided with the semicircle moving vane of 2 hinge shapes in valve body, and moving vane is connected along last sealing round platform sealing contact with valve body is interior; In the valve body on moving vane top, be provided with and grip axle; Be fixedly connected with at least 1 anticreep support in the outer of valve body.
In order to reach better installation and fixed effect, the connecting portion of described anticreep support and valve body outer is circular-arc, and the other end of anticreep support is ratchet-like, evenly is provided with 4 anticreep supports in the outer of valve body.
This utility model is simple in structure, can select raw materials such as existing Nitinol for use, and adopts the processing and manufacturing of conventional technology, and cost is low, implements easily.
In functional pneumonectomy operation, the patient can clamp the axle that grips in the valve body with operating forceps, inserts check valve under the branchofiberoscope direct-view, and is simple to operate, easy for installation, grasps easily.This functional pneumonectomy check valve, in valve body, be provided with the semicircle moving vane of 2 hinge shapes, along with the mechanical change in the respiratory, moving vane can flow gas unidirectional by automatic shutter, guarantee the far-end that enters that extraneous air can be the least possible, and the gas of far-end, slough and rheuminess thing can be external with the breathing eliminating, thereby effectively reach the purpose of aseptic pulmonary atelectasis, and clinical effectiveness is good.Owing to be provided with ratchet-like anticreep support in the outer of valve body, deviate from after can effectively preventing to insert, be not easy to come off.
Has simple in structure, advantage such as processing and fabricating is easy, cost is low, clinical manipulation is simple, easy to install, easy grasp, clinical effectiveness are good, be not easy to come off.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of this utility model.
Fig. 2 is the plan structure sketch map of Fig. 1.
Fig. 3 is the structural representation of moving vane place open mode.
Among the figure: 1 valve body, 2 moving vanes, 3 grip axle, 4 sealing round platforms, 5 anticreep supports, 6 sharfs.
Specific embodiments
This utility model is further described with the embodiment that provides below in conjunction with accompanying drawing.
With reference to accompanying drawing, this functional pneumonectomy check valve is made of cylindric valve body 1, and the semicircle moving vane 2 of 2 hinge shapes is housed on the sharf 6 of valve body lower portion, when moving vane falls, and realize that along last sealing round platform 4 the sealing contact is connected in the valve body.In the valve body on moving vane top, be provided with and grip axle 3.Be fixedly connected with 4 anticreep supports 5 in the outer of valve body, the connecting portion of anticreep support and valve body outer is circular-arc, and the other end of anticreep support is ratchet-like.
This utility model applicant presses the foregoing description, implement this functional pneumonectomy check valve with Nitinol, 8 millimeters of cylindric valve body external diameters, 7 millimeters of internal diameters, high 8 millimeters, 3.4 millimeters, thick 0.3 millimeter of semicircle moving vane radius, the anticreep support is long and wide 1 millimeter, 1.6 millimeters of ratchet outer rim highest points.Show through inner zoopery and clinic trial, this functional pneumonectomy check valve, simple and compact for structure, processing and fabricating easily, compare with similar products at home and abroad cheap, particularly very simple, easy for installation, the medical worker of clinical manipulation is easy to grasp, the histocompatibility of Nitinol is better, result of use is desirable, install and fix and reliably be not easy to come off, be subjected to medical worker and patient's welcome and favorable comment, behind the clinical expansion, application promise in clinical practice will be arranged.
