Description

Pressure-reducing wheelchair

Technical Field

The invention relates to the technical field of wheelchairs, in particular to a decompression wheelchair.

Background

The wheelchair is the indispensable medical equipment in the inconvenient person's of lower part action life, and the wheelchair under the prior art adopts the skeleton that is used for supporting the patient and the wheel combination that is used for the walking, and the purpose that lets the patient realize riding instead of walk is retreated through the advancing of control wheel.

However, the wheelchair in the prior art does not have a hip decompression function, when the upper body of a patient is pressed on the hip for a long time, local tissues are pressed for a long time, and tissue ulceration and necrosis caused by continuous ischemia, hypoxia and malnutrition occur, so that the situation that pressure sores need to be assisted by other people to move on the one hand and need to be pressed on the palm by means of upper limb strength to avoid movement needs to be avoided, on the one hand, the assistance of other people is needed, on the other hand, for the patient who lacks the same weak upper limb strength to exercise, the palm pressing is too hard to consume physical force, and the palm pressing with short time also does not achieve the good purpose of preventing pressure sores.

Disclosure of Invention

The invention aims to solve the problems and provides a decompression wheelchair.

In order to achieve the purpose, the invention adopts the following technical scheme:

the table mat comprises a framework, wherein at least one table mat capable of being axially turned over is arranged on the upper top surface of the framework, one end of the table mat forms a plane together with the upper top surface of the framework when being turned over to the upper side, and a bulge is formed on the upper top surface of the framework when the other end of the table mat is turned over to the upper side;

the back rest is rotatably arranged on the framework and is connected with the table mat through a transmission mechanism and controls the table mat to turn axially;

the tail of the framework is provided with a support piece extending upwards, and an elastic support is arranged between the support piece and the backrest.

Optionally, the backrest is perpendicular to the upper surface of the framework under the elastic force of the elastic support without external force.

Optionally, the transmission mechanism is a step-up transmission mechanism.

Optionally, the width of the skeleton is 50-70 cm.

Compared with the prior art, the invention has the following advantages:

the invention does not need the assistance of other people and does not need to press palmtop with the help of the strength of upper limbs to prevent pressure sores, the turning of the table mat is driven by the simple and effortless action of backward bending of the patient to enable the gravity center of the hip to fall to the other side, so that the effective pressure reduction is carried out on the hip at one side of the hip, the pressure sores can be effectively prevented by the back and forth of the two sides for a plurality of times at regular time, the operation can be carried out at any time and any place, the applicability is wide, the table mat is a plane in a normal state, the discomfort of the patient can not be caused, and meanwhile, the table mat can be driven to.

Drawings

FIG. 1 is a schematic structural view of a pressure-reducing wheelchair according to the present invention;

fig. 2 is a top view of the inventive cage.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1, the framework is welded and assembled by a steel frame 1 to form a table and chair shape, the upper top surface of the steel frame 1 is a plane, and the bottom end of the steel frame 1 is provided with a traveling wheel, which is a common technology in the market and is not described herein again.

Two table pads capable of being turned over axially are arranged on the upper top surface of the steel frame 1, and correspond to two sides of the hip of a patient, as shown in fig. 2.

The table mat is composed of a hollow arched plate 7, one end of the hollow arched plate 7 is plane, the other end of the hollow arched plate is arched, the table mat has good pressure resistance, and the middle of the hollow arched plate 7 is provided with a mandrel 11 which is fixedly connected with the hollow arched plate and can drive the hollow arched plate to axially rotate.

The plane end of the hollow arch-shaped plate 7 forms a plane together with the upper top surface of the framework when being overturned to the upper side, and a bulge is formed on the upper top surface of the framework when the arch surface end of the hollow arch-shaped plate 7 is overturned to the upper side, and the bulge can jack up one side of the hip of a patient.

The frame is rotatably provided with a backrest, the backrest is a back plate 2 made of hard material, the two back plates 2 correspond to the hollow arch plates 7 in position and respectively control the hollow arch plates 7 on the two sides to move.

Two backplate 2 all rotate through the pivot fixed connection with it and connect the top surface on steelframe 1, because pivot and 2 fixed connection of backplate, the pivot extends the side and interference fit of steelframe 1 and has driving gear 8, and driving gear 8 meshes has driven gear 9, and driven gear 9 rotates on steelframe 1 through the pivot, and driven gear 9 passes through belt drive mechanism 10 and is connected with mandrel 11. In the preferred embodiment of the present invention, the two belt pulleys of the belt transmission mechanism 10 are one large and one small, and the large and small belt pulleys jointly constitute the speed increasing transmission mechanism, the large belt pulley is coaxially arranged with the driven gear 9, and the small belt pulley is coaxially arranged with the spindle 11.

The integrated into one piece has ejector pin 4 upwards at the last top tail of steelframe 1, and the quantity of ejector pin 4 is two, and the common welding in top of two ejector pins 4 has horizontal pole 5, and this horizontal pole 5 should adopt the higher material of intensity for provide the support for backplate 2.

The spring 3 is welded between the ejector rod 4 and the back plate 2, and the spring 3 plays a role in stabilizing, so that the back plate 2 and the hollow arched plate 7 linked with the back plate can move only by overcoming the elasticity of the spring 3. In the preferred embodiment of the present invention, the spring 3 is installed in the backboard 2 to be perpendicular to the upper surface of the steel frame 1.

It is worth mentioning that the width of the steel frame 1 is much larger than the average hip width of 30cm, for example 60cm, so that the patient can lean backward to one side without being too narrow to enable the back plates 2 on the two sides to move synchronously.

When the patient sits for too long on the wheelchair, when needing the buttock decompression, only need to lean on backward to one side that the buttock needs the decompression, backplate 2 uses the pivot to overcome the elasticity upset of spring 3 as the fulcrum, the pivot passes through driving gear 8, driven gear 9's intermeshing transmission further passes through belt drive mechanism 10 with this moment and increases the speed and transmit to mandrel 11, mandrel 11 and then drives hollow arch shaped plate 7 and produce great upset, make its archway upset to the upside, patient's focus is fallen on opposite side buttock this moment, this side can effectual decompression by the buttock of jack-up.

While the foregoing disclosure shows illustrative embodiments of the invention, it should be noted that various changes and modifications could be made herein without departing from the scope of the invention as defined by the appended claims. The functions, steps and/or actions of the method claims in accordance with the embodiments of the invention described herein need not be performed in any particular order. Furthermore, although elements of the invention may be described or claimed in the singular, the plural is contemplated unless limitation to the singular is explicitly stated.
