Abstract

The utility model comprises a vacuum pump, a soft tube, an external-connection sleeve, a sealing ring, a push rod, an air core, an internal-connection tube, a spring, a vacuum seat, a plastic bag and plastic particles. The vacuum pump works under the function of a power supply and produces negative pressure so that air in the plastic bag is exhausted out of the plastic bag to form negative pressure. The plastic particles in the plastic bag are tightly gathered together to form hard blocks along with the increase of the negative pressure according to the shapes of the different positions of a human body so that the position of the human body are carried out with hardening fixation.

Description

Body position fixture

This utility model relates to a kind of medical apparatus and instruments, especially relates to a kind of being used for the different parts of human body is carried out fixed body position fixture.

In medical treatment clinically, the radiotherapy such as fracture, malformation correction, malignant tumor all needs some position of human body is fixed.Fixed for fixing plaster bandage, the plintlet of adopting usually of disease patients' such as fracture position.Plaster bandage is to spread gesso with wide screen eye gauze to roll and form.During clinical practice, plaster bandage is immersed in the water fully, be wrapped in after soaking and suffer from the body, harden until gypsum crystallization.Small splints fixation can keep the fracture segment part to be relatively fixed, and control is to the disadvantageous activity of fracture site.Though above-mentioned two kinds of methods can be fixed the position of human body, in clinical practice,, can influence the blood circulation of limbs as too tight with getting on the Gypsum Fibrosum, produce the sensation of pain, numbness.Gypsum Fibrosum also may bring out decubital ulcer on the metastomium of human body.Gypsum Fibrosum itself also exists the drawback that fractures easily.And small splints fixation is used for the stable transverse fracture of long diaphysis more.Also to be aided with traction therapeutic to unstable fracture.And for articular fracture, open fracture, skin have inflammation person, can't use small splint immobilization.Present medical fixing means can't carry out ideal omnibearing position to human body to be fixed.

The purpose of this utility model provides a kind of deficiency that remedies existing medical apparatus and instruments and medical skill, promptly in medical procedure, do not remove under the situation of fixtures such as Gypsum Fibrosum, just can carry out x-ray fluoroscopy, rectification, affirmation to the illness position, and can carry out the body position fixture of moulding according to the form of partes corporis humani position.

The purpose of this utility model be achieved in that it comprise vacuum pump, flexible pipe, external cover, sealing ring, push rod, gaseous core, in connect cover, spring, vacuum bed, the plastic bag once soft pipe connection is arranged on the vacuum bed, plastic bag is built-in with plastic pellet.

This utility model is owing to adopt such scheme, except having the conventional fixed function of existing medical skill to the human body position, also have any moulding, advantage such as use are repeatedly carried out in the partes corporis humani position, and the size of available control vacuum regulates the tensile force at fixing human position, remedied the defective of conventional existing medical skill.

Below in conjunction with drawings and Examples the specific embodiment of the present utility model is described in further detail.

Accompanying drawing is a structural representation of the present utility model.

With reference to accompanying drawing, vacuum pump 1 of the present utility model is communicated with an end of flexible pipe 2, the other end of flexible pipe 2 is communicated with external cover 3, connects cover 7 in external cover 3 usefulness are threaded, and external cover 3 is built-in with push rod 4, the end face of push rod 4 is built-in with sealing ring 5, vacuum bed 9 is built-in with spring 8, gaseous core 6, in the end face of gaseous core 6 with in connect between the end face of cover 7 and be equipped with sealing ring 5, spring 8 acts on gaseous core 6 and the vacuum bed 9, vacuum bed 9 is communicated with plastic bag 10 through flexible pipe 2, and plastic bag 10 is built-in with plastic pellet 11.

The task that this utility model proposed is further finished by following technical proposals: plastic bag can be spherical, cylindrical, cuboid, plastic pellet diameter in the plastic bag is more than or equal to 1mm, smaller or equal to 10mm, the volume of plastic pellet accounts for the volumetrical 20%-80% of plastic bag.

This utility model can be fixed different parts on the human body.At first, wrap up the winding moulding on the plastic bag 10 with needing fixed position to be placed on the human body.Then, connect in external cover 3 is screwed on the cover 7, simultaneously, push rod 4 roof pressure gaseous cores 6, sealing ring 5 on the gaseous core 6 is moved along axial line synchronously, thereby make plastic bag 10, be in conducting state through flexible pipe 2, vacuum bed 9, gaseous core 6, push rod 4, flexible pipe 2 to the gas circuit between the vacuum pump 1.

Vacuum pump 1 of the present utility model is worked under the power supply effect, and produces negative pressure, causes the air in the plastic bag 10 to be discharged outside the plastic bag 10, forms negative pressure.Along with the increase of negative pressure, the plastic pellet 11 in the plastic bag 10 will closely be reunited and form lump together according to the shape of human body different parts, hardens fixing to the position of human body.As long as negative pressure does not disappear, sclerosis is fixing with regard to sustainable maintenance.After moulding is finished using, can back out external cover 3 when a kind of fixedly from the interior cover 7 that connects, roof pressure gaseous core 6 disappears the negative pressure in the plastic bag 10, just can reuse fixedly moulding.

Claims

1. body position fixture, it comprise vacuum pump, flexible pipe, external cover, sealing ring, push rod, gaseous core, in connect cover, spring, vacuum bed, it is characterized in that: the plastic bag once flexible pipe UNICOM is arranged on the vacuum bed, and plastic bag is built-in with plastic pellet.

2. body position fixture according to claim 1 is characterized in that: plastic bag can be ball-type, the cylinder bodily form, cuboid.

3. body position fixture according to claim 1 is characterized in that: the diameter of plastic pellet is more than or equal to 1mm, smaller or equal to 10mm.

4. body position fixture according to claim 1 is characterized in that: the volume of plastic pellet accounts for the whole volumetrical 20%-80% of plastic bag.
