Abstract

The utility model discloses a separating diaphragm, including the spacing block and the long banding connection piece of circular form, thereby be provided with the one-way closure that realizes opening or closing because of atmospheric pressure changes on the spacing block, be provided with the opening on the connection piece, and the outside that is located the opening is provided with the sealing. The blocked drainage pipeline can be washed through the device, and medical staff is not needed to dredge manually.

Description

Separating diaphragm

Technical Field

The utility model relates to the field of medical equipment, more specifically say, it relates to a separating diaphragm.

Background

Closed thoracic drainage or negative pressure drainage is a common clinical operation in thoracic surgery, and is an effective method for treating empyema, traumatic hemothorax, pneumothorax and spontaneous pneumothorax. At present, the drainage device of the pleural effusion in China mainly comprises drainage bag drainage, water-sealed bottle negative pressure drainage and the like, and the drainage mode is also divided into an intercostal tubule intubation method, an intercostal thick tube intubation method and a ribbed bed intubation method according to the illness state of a patient.

But current drainage device is when the drainage, and the drainage tube is discharged with gas, liquid or the pustule that exists, the clot of patient's thorax together in same pipeline drainage, and at this drainage in-process, pustule, clot block up the pipeline easily to can't reach the effect that lasts the drainage, need medical personnel manually to dredge the pipeline this moment, bring very big inconvenience for medical personnel.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a divide diaphragm is a device for solving above-mentioned technical problem.

The above technical purpose of the present invention can be achieved by the following technical solutions: the utility model provides a separating diaphragm, includes the spacer of circular form and long banding connection piece, thereby be provided with the one-way closure that realizes opening or closing because of atmospheric pressure changes on the spacer, be provided with the opening on the connection piece, and the outside that is located the opening is provided with the sealing.

Further defined, the cross section of the sealing part is in a shape like a Chinese character 'tu'.

Further defined, the spacer has an upwardly convex surface with a curvature.

Further, the isolation sheet is provided with a groove on the outer side of the convex surface.

Further inject, the connecting piece and the back of the sealing part are provided with a mounting groove.

Further limit, the free end of connection piece just is located the outside of mounting groove and is provided with joint head.

Further limit, the one-way sealer includes two shrapnels that the laminating set up mutually.

The liquid secretion in the chest cavity of the patient is drained to a collecting container through a liquid drainage path of a drainage pipeline, and the drainage pipeline can be blocked due to pustules and blood clots in the drainage process. The utility model is used for in the gas circuit of washing of ventilating, the solenoid valve is opened, and external gas gets into, gets into through the through-hole and keeps apart the chamber, and when the atmospheric pressure value of keeping apart the chamber was greater than the atmospheric pressure value of drawing the liquid way, the one-way closure of separating the diaphragm was opened, and gas gets into the drainage pipeline, washes the drainage pipeline.

To sum up, the utility model discloses following beneficial effect has: the device is a novel device used in thoracic drainage or negative pressure drainage equipment; the novel medical drainage device is applied to a flushing gas circuit, flushes the blocked drainage pipeline, does not need manual dredging of medical personnel, and is convenient and convenient.

description of the drawings: 431. a separator; 432. connecting sheets; 433. a port; 434. a sealing part; 435. a groove; 436. mounting grooves; 437. a convex surface; 438. a clamping head; 48. a one-way sealer.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, a separating diaphragm is made of elastic non-metallic material. The separator sheet includes a circular spacer sheet 431 and an elongated connecting sheet 432, and the connecting sheet 432 is provided with a through hole 433, and a seal portion 434 is provided outside the through hole 433. The cross-sectional shape of the sealing portion 434 is a "convex" shape. Pressure is applied to the sealing part 434 of the split diaphragm, and the sealing part 434 is in a convex shape, so that a better sealing effect is achieved.

The one-way sealer 48 is two pieces of elastic sheets which are attached to each other and made of rubber. When the ventilation is performed, the two plastic elastic sheets are opened by air pressure, and when the ventilation is not performed, the two plastic elastic sheets are restored to the closed state. When the door is opened or closed, the isolating sheet 431 is deformed by air pressure; in order to improve the deformability of the spacer 431, the spacer 431 is designed to be convex upward with a curved convex surface 437. A groove 435 is provided on the outer side of the convex surface of the spacer 431. The connecting piece 432 is provided with a mounting groove 436 on the back of the sealing portion 434. A snap joint 438 is provided on the free end of the connecting piece 432 outside the mounting groove 436.

The specific embodiments are only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiments without inventive contribution as required after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
