Abstract

The utility model relates to a medical cupping, comprising a tank body and an air pump. A through hole is arranged on the tank body. A valve cap and a valve rod are arranged out of the through hole. The air pump is a piston composed of a handle housing, a piston body, a piston rod and a plug. A pump body is in the shape of the Chinese character 'tu'. A pump mouth is matched with the valve cap. A return spring supports the piston. The utility model has the advantages of convenient use and non-danger of skin scald.

Description

A kind of medical gas tank that pulls out

It is a kind of jar that this utility model relates to, and specifically a kind ofly can produce the medical treatment device that negative pressure is used for the treatment of some disease of human body in jar.

In Chinese medicine, treat some commonly encountered diseases with the method for cupping, as rheumatalgia, arthritis etc. often obtain beyond thought effect.The cupping jar that uses in the prior art generally is the simple tank body made from glass or ceramic with hemispherical or garden cylindrical cavity, in jar, put into combustible during use and make it burning, rapidly tank body is buckled in the lesions position of human body simultaneously, the burning of combustible produces negative pressure in jar, make the tank body body foci portion that is adsorbed on body tightly.The existing problem of existing cupping jar mainly contains two, the one, because the generation of negative pressure is that combustible is due to the jar internal combustion, if it is careless when operation, easy scalded skin, the secondth, the size of the negative pressure that produces is difficult to control, when negative pressure is excessive, easy injured skin, when negative pressure is too small, therapeutic effect is bad, adsorbs not firm coming off sometimes even with skin, must carry out the operation second time.

The purpose of this utility model is a kind of medical gas tank that pulls out that utilizes the air pump principle to produce negative pressure in cup of design, and this group gas tank does not use combustible in the treatment operation, and a jar intravital vacuum magnitude can be adjusted as required.

The medical gas tank that pulls out of this utility model is to realize like this, it comprises tank body and air pump two parts composition, and the bottom of its tank body 3 is provided with through hole 4, and the tank body external stability of through hole 4 has cup-shaped bonnet 2, the bonnet center is porose 5, and axial section is that the valve rod 1 of I font passes from hole 5 and can move axially; Air pump comprises the pump housing, handle housing, piston and spring, and the pump housing is the convex shape tubular body, and the internal diameter of pumping hole 10 matches with bonnet 2 external diameters, opens hole 11 on the pump housing; Handle housing 5 comprises upper and lower casing two parts, is fixedly connected to form two tubular housings by screw 8, back-moving spring 6 is installed and as the slide rail of piston body 7 poles in the tubular housing; Piston comprises piston body, piston rod and chock plug, and piston body 7 is the mountain font, and two columnar supports are supported by spring 6, and piston rod connects chock plug 9 and piston body 7, and chock plug 9 is the garden cylindricality, studs with O-ring seals on the chock plug 9, its external diameter matches with pump housing internal diameter.

The medical gas tank that pulls out of this utility model has overcome negative pressure in its jar of shortcoming of traditional cupping jar preferably, and by the air pump generation of bleeding, the big I of negative pressure is by the number of times adjustment of bleeding.This pulls out gas tank and does not use combustible, not the careless scalded skin of reason.It is simpler, easy to use that this utility model pulls out the gas tank structure, is applicable to hospital, and family uses as medical device commonly used.

Accompanying drawing 1 is a tank structure schematic diagram of the present utility model.

Accompanying drawing 2 is an air pump structure principle chart of the present utility model.

Embodiment:

This utility model is made up of air pump and tank body two parts.Wherein air pump is by handle housing 5, back-moving spring 6, and piston 9, tapping screw 8, the O RunddichtringO 9 and the pump housing constitute.Handle housing is by last, and lower house two parts are formed, and are connected and fixed by four tapping screws 8 between them.There are two cylindrical cavities inside, and the pole of device piston body is played the track effect.Also adorn simultaneously two back-moving springs 6 of piston.The handle housing bottom connects with the pump housing, and the O RunddichtringO on the pump housing and the piston constitutes the chamber of bleeding, and reaches the purpose of bleeding from tank body.One passage 11 is arranged at pump housing top, when piston is bled when reaching the stroke end, by this passage in the pump housing, provide moment relatively high pressure, close the valve rod 1 on the tank body.Piston O RunddichtringO groove is provided with the backhaul passage, plays the backhaul venting.

Tank body part is by valve rod 1, bonnet 2, and tank body 3 constitutes, and wherein the cylindrical surface of valve rod 1[font bottom is provided with oil storage tank, and is reliable to guarantee its flexible movements on tank body 3, and the bottom is circular and tank body fitted seal gas.Bonnet 2 is fixed on and guarantees the valve rod location on the tank body 3, and the bonnet upper inside also is provided with oil storage tank, reduces the friction between valve rod and the bonnet.
