Abstract

The invention discloses a medical wheel chair. The two sides of a chair frame are respectively connected with a movable armrest through a hinge shaft; the rear part of the chair frame is connected with a movable backrest through a hinge shaft; and a connecting locking device is arranged between the backrest and the chair frame. A restraint belt is mounted at one side of the chair frame; a base plate is mounted at the upper end of the movable backrest; and an infusion support is mounted at one side of the chair frame. Compared with a current wheel chair, the medical wheel chair can be used for solving the problems that the current common wheel chair blocks medical workers to implement thoracocentesis operations on patients and has bad fixation effects on the patients when being used for thoracocentesis.

Description

Medical wheelchair

Technical field

The present invention relates to manufacture technology field of medical appliance, especially a kind of wheelchair that is specially adapted to implement the thoracentesis operation.

Background technology

When the people because of thoracic injury or other thoracopathy causes a large amount of hydrops in thoracic cavity, when pneumatosis causes dyspnea, circulatory failure, need in time carry out thoracentesis, extract too much hydrops and pneumatosis on the one hand out, the symptom of reduction of patient, inspect simultaneously that the hydrops smear is cultivated by ready samples, cytolgical examination etc., to help diagnosis and treatment.And the doctor is doing to the patient in the thoracentesis process, requires the patient can keep certain position to increase the width of intercostal space, will keep the stability of position to be beneficial to puncture procedure simultaneously, therefore need provide comfortable, a safe and stable environment to the patient; In the thoracentesis process, sometimes owing to the variation of the state of an illness also will be infused to the patient, even need rapidly the patient is sent into the rescue of ward or rescue room on the other hand.Hospital doctor is used for settling patient's facility that common seat, sick bed are arranged when implementing thoracentesis to the patient at present, these facilities all are difficult to reach above-mentioned requirements, move for convenience and suffer from, can use common medical wheelchair, this wheelchair is used for implementing thoracentesis and has following deficiency: the one, and operation causes very inconvenient obstruction to the handrail of its both sides for thoracentesis; The 2nd, the patient is sitting on this wheelchair, can't implement the thoracentesis operation of carrying out from the back; The 3rd, this wheelchair often only is provided with brake unit at trailing wheel, and its two front-wheel is to be in free movement state, and this structure in the thoracentesis operating process patient is taken place easily and moves and slip up.

Summary of the invention

The present invention will provide a kind of medical wheelchair, and this medical wheelchair hinders medical personnel the patient is implemented thoracentesis operation, the problem bad to patient's fixed effect in the time of can solving existing common wheelchair for thoracentesis.

In order to address the above problem, the technical solution used in the present invention is: this medical wheelchair, include the chair frame, and be contained in the front-wheel on this chair frame, two trailing wheels, between described chair frame and described two trailing wheels, rear wheel brake is housed, between described chair frame and described front-wheel, front wheel brake is housed; Described chair frame both sides are connected with a movable hand rail respectively by jointed shaft; The rear portion of described chair frame is connected with a rotatable movable back that opens or closes by jointed shaft, is equipped with to be connected locking device between the described rotatable movable back that opens or closes and described chair frame.

In the technique scheme, scheme can also be more specifically: the connecting portion of described handrail and described chair frame is provided with and swings up and down the position rotating limit device, be connected with restraining belt for immobilized patients in described chair frame one side, fasten in the both sides of described chair frame and the patient can be fixed on this chair by this restraining belt, so that medical personnel implement the operation of puncturing; Described movable back upper end can also be provided with one in use for the patient crawl on it, horizontally disposed backing plate, this piece backing plate can be connected through the hinge on described movable back, and tipping has folding travel(l)ing rest between this backing plate and described movable back; Above-mentioned this backing plate also can be connected by jointed shaft with a limited block that is contained in the backing plate storehouse, allow this by manually pulling out outside the described backing plate storehouse, or hide in this backing plate storehouse, be provided with the cross bar that is used for supporting backing plate that is horizontally placed between the left and right sides in the upper end of described movable back, in the time of outside described backing plate is pulled out described backing plate storehouse, allow this backing plate rest on this cross bar, described backing plate storehouse is preferably disposed on the rear of described movable back.Can also be equipped with by sleeve pipe and be contained in the drip stand that the peg in this sleeve pipe constitutes in described chair frame one side, described sleeve pipe upper end is provided with and limits the lock nut that described peg upwards rises height.

Owing to adopted such scheme, the present invention compared with prior art has following beneficial effect:

1. be convenient to that medical personnel are multi-faceted to carry out the thoracentesis operation to the patient, the patient can face forward be sitting on this chair, can allow the patient face the rear from the rear to be sitting on this chair by opening movable back, by regulating the height that the both sides movable hand rail rises, can allow medical personnel from both sides or the place ahead of this chair the patient be carried out the thoracentesis operation; To the brake unit that the front and back wheel of fixing and this chair of patient arranges, can allow patient's relative fixed by restraining belt, prevent movable error or the failure that causes the puncture operation because of the patient; In addition, allow the patient crawl on the backing plate at movable back rear, perhaps both hands being helped on the handrail that rises in both sides to increase patient's intercostal width, is beneficial to the carrying out of puncture operation;

2. provide comfortable, a stable environment to the puncture object, when the patient is carried out thoracentesis, the patient can cosily crawl on backing plate in a long time, perhaps both hands are helped on the handrail that rises in both sides, difficult generation is put hands up for a long time and is produced tiredly, also can prevent this sleepiness and changes physical effects puncture operation; Can more stably keep certain position in order to the carrying out of puncture during the puncture of different parts, reduce the error of puncture;

3. after this chair adds drip stand, infuse to the patient in the operation process of being convenient to puncture or the front and back of puncture operation;

4. convenient movement to the thoracentesis object, before and after the puncture operation, can conveniently shift the puncture object by this chair, the weak patients that is not only applicable to inconvenient activity moves to the operation place and carries out thoracentesis, and the back fast moving patient of being convenient to puncture rescues.
