Abstract

The utility model relates to a deroppilation apparatus for medical drainage, belonging to the medical appliance, which is particularly suitable for the drainage deroppilation of the drain after a surgical operation in clinical care. A pumping mixing shaft is driven by a micro motor. The front part of the mixing shaft is provided with screw threads or blade wheels, and a shaft sleeve, and the outer part of the mixing shaft is sheathed with a sleeve pipe. The front part of the sleeve pipe is provided with a drain suction port along the circumference. The rear part of the sleeve pipe is provided with an eduction pipe. The tail end of the sleeve pipe is connected with the body of the motor. The motor is provided with a handle and a manual switch. When in work, the sleeve pipe and a drainage pipe drum are sheathed together, so the opening of the drainage pipe corresponds to the suction port of the sleeve pipe. The utility model has the advantages of high pumping efficiency, good effect, convenient operation, no injury to the human body, etc.

Description

Deoppilation apparatus for medical drainage

This utility model relates to a kind of medical equipment, particularly a kind of medical drainage dredge that is used to aspirate purulent core, the use of sludged blood obstruction drainage tube.

In medical treatment was clinical, particularly behind surgical operation, placing drainage tube was an important treatment measure.For example: fracture of rib merges hemopneumothorax, all need to place closed thoracic drainage tube behind empyema and the most of thoracic surgery, at the Urology Surgery hyperplasia of prostate, bladder cancer postoperatives etc. need to place bladder creating-fistula, and these drainage tubes must guarantee unobstructed, just can reach the purpose of treatment disease, promptly the drain in the drainage lumens be drawn naturally, the drainage tube that uses is the flexible pipe that leading portion has side opening at present.But these drainage tubes are usually stopped up by purulent core or sludged blood clinically, do not reach the purpose of effective drainage.Then to use syringe vacuum suction or flushing at this moment, make drainage tube unobstructed.But syringe vacuum suction or developing result are not good, even invalid, and some also needs operation again to remove sludged blood or purulent core, brings very big misery to patient.In addition, in surgical operation, use the negative pressure device of suction pump leading portion at present, also be easy to be stopped up, make troubles, influence normal operative speed, prolong operating time to surgical doctor by sludged blood as metal tube.

The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of mechanical type medical drainage dredging machine that carries out continuous sucking and sludged blood, purulent core can be blended is provided.

The purpose of this utility model is to realize by following technical scheme.Stirring axle with micro motor for driving one suction rotates, stir in suction and to be set with sleeve pipe on the axle, the sleeve pipe rear portion is connected with motor, on sleeve pipe leading portion perisporium, offer inlet hole, be provided with fairlead at the sleeve pipe back segment, by hand switch control electric motor starting, stir the axle rotation thereby drive suction, in stirring a rotation process, produce suction airstream backward.In use, with sleeve pipe and drainage tube mutually casing and make the perforate on the drainage tube corresponding with leading portion perforate on the sleeve pipe together, under the suction airstream effect, in sleeve pipe, and stir axle and blend and take out and pump by the suction that is rotated by the hole seepage flow of drainage tube for drain.

Fig. 1 is a section of structure of the present utility model.

Fig. 2 is the section of structure of another embodiment of this utility model.

Fig. 3 is the A among Fig. 2---the A cutaway view

In conjunction with the accompanying drawings structure of the present utility model and embodiment are described as follows:

See that Fig. 1 and Fig. 2 are movably installed with a suction and stir axle 2 in sleeve pipe 5, suction is stirred axle 2 back segments and is connected with micro machine 1 output shaft 1b, at the spaced apart drain inlet hole 5a that is provided with of sleeve pipe 5 leading portions, the external diameter of sleeve pipe 5 is φ 8～13, the diameter of inlet hole 5a is φ 2～5mm, be provided with a drain fairlead 5b who communicates with sleeve pipe 5 inner chambers at sleeve pipe 5 back segments, sleeve pipe 5 rear ends are connected with the flange 1a of motor, and the handgrip 9 of micro machine 1 is provided with control starting switch 10.

Stir between axle 2 back segments and the hollow sleeve 5 in suction and to be provided with axle sleeve 3, there is a sealing gasket 4 the axle sleeve front portion, suction is stirred axle 2 and is screw rod, and pitch is that the impeller 7 of 5～10mm or interval suit constitutes with axle sleeve 8, and sleeve pipe 5 rear ends are that bolt is connected with the flange 1a of motor 1.It is 50～100mm that axle 2 threaded portion length are stirred in suction, sleeve pipe 5 meshed portion length are 50～80mm, vane type suction shaft 2 is by the rotating shaft body and be sleeved on impeller 7 on the rotating shaft body and the axle sleeve 8 between the impeller 7 constitutes, and twists on the axle sleeve 8 of forefront or impeller 7 front end rotating shaft bodies and is placed with locknut 6.

Work process of the present utility model is as follows:

Before the use, should be with sleeve pipe 5, suction is stirred axle 2 and is pulled down and carry out disinfection, under aseptic condition, be connected then with motor 1, coat lubricant at sleeve pipe 5 outer surfaces and insert in the drainage tube tube chamber of having placed, and make the drain inlet hole 5a of sleeve pipe 5 leading portions corresponding with the side opening of the drainage tube leading portion of having placed.Press micro machine switch 10 at last motor 1 is started, drain is promptly by in the inlet hole 5a scution bush inner chamber on the sleeve pipe 5, and is pressed through fairlead 5b after blending backward and discharges.

On this utility model fairlead 5b, connect negative pressure device, start micro machine simultaneously, can become the blockage resisting suction pump, be applied in the surgical operation.
