Abstract

The utility model relates to a medical physical therapy cupping apparatus. A piston structure is composed of a cupping jar body and a cupping jar core; a row of scale indication lines is labeled on the external surface of the cupping jar body, and correspondingly, the external surface of the cupping jar core is provided with a row of positioning devices, so that the utility model can take different negative pressure treatments according to different diseases and the different seriousness of the diseases. The medical physical therapy cupping apparatus avoids the phenomena of skin injury duo to burning, blood congestion under the skin, cup dropping, etc. The clinical therapeutic effect of the cupping can be improved.

Description

Suction metering cupping device

This utility model relates to and a kind of medical physiotherapeutic cup apparatus.

At present, the employed suction cup of hospital is " cupping jar ", it was used till today from time immemorial, need during treatment fire probeed into rapidly and make it produce negative pressure in the jar, cover the treatment position the patient then immediately, this therapeutic device happens occasionally because of the burn phenomenon of patient skin of fire, and because the negative pressure that burning hot expanded air produces does not have measurement concept, be difficult for grasping, make negative pressure cross conference and produce patient's subcutaneous extvavasated blood, negative pressure is too small can fall jar phenomenon.

The purpose of this utility model is exactly in order to overcome above-mentioned shortcoming, and a kind of sucking type metering suction cup is provided, and it need not produce negative pressure by fire, and is without any side effects to the patient, and evident in efficacy.

This utility model is made up of a tank body and a jar core, tank body is a hollow circular cylinder, its circumferential outer surface indicates row's scale indicatrix along axis, the jar core is a solid cylinder, the intrinsic circular plate type rubber closure of its front end, and the external diameter of rubber closure and the internal diameter of tank body match, the external diameter of jar core is less than the internal diameter of tank body, make tank body and jar core form piston structure, circumferential outer surface at the jar core is equipped with row's spring key along axis, spacing on spacing between each spring key and the tank body circumferential outer surface between some scale indicatrixs is identical, and the circumferential outer surface that is preferably in jar core is equipped with symmetric two row's spring keies along axis, makes its locating effect better.

Figure of description:

Fig. 1 is this utility model overall structure sketch map;

Fig. 2 is this utility model tank body sketch map;

Fig. 3 is this utility model jar core sketch map.

During use such as Fig. 1, front end cover with tank body 1 is pressed on the position of the required treatment of patient earlier, this moment, the rubber closure 3 of jar core 2 front ends was concordant with the front end face of tank body 1, pull back jar core 2 then, the rubber closure 3 that drives its front end moves backward, make between tank body 1 and jar core 2 and form negative pressure, the doctor can execute art by metering according to patient's the state of an illness, rubber closure 3 is alignd with a certain scale indicatrix 5 on tank body 1 circumferential outer surface, corresponding two spring keies 4 up and down on this moment jar core 2 circumferential outer surfaces are stuck in the rear end face of tank body 1 just, regulating scale indicatrixs 5 different on rubber closure 3 and tank body 1 circumferential outer surface aligns, with regard to the vacuum magnitude in scalable this utility model, the corresponding spring key 4 on jar core 2 circumferential outer surfaces plays the role of positioning simultaneously.

Know P by the physics ₀V ₀=PV conversion back P=P ₀V ₀/ V, wherein V ₀Represent gas volume under the original state, V representative suction back gas volume, P ₀Represent the pressure under the original state, the pressure after the P representative suction can be found out by following formula, volume V is big more, and pressure P is more little, and promptly negative pressure is big more, this utility model indicates the scale indication, introduces measurement concept, can be because of the difference of disease, the difference of state of an illness weight, and take different negative pressure treatments, avoided because of fiery skin ambustion subcutaneous extvavasated blood, fall phenomenons such as jar, the clinical efficacy of cupping therapy is improved greatly.

Claims

1, a kind of sucking type metering suction cup, it is characterized in that it is made up of a tank body 1 and a jar core 2, tank body 1 is a hollow circular cylinder, its circumferential outer surface indicates row's scale indicatrix 5 along axis, and a jar core 2 is a solid cylinder, the intrinsic circular plate type rubber closure 3 of its front end, the internal diameter of the external diameter of rubber closure 3 and tank body 1 matches, the external diameter of jar core 2 is less than the internal diameter of tank body 1, and tank body 1 and jar core 2 are formed piston structures, along axis one row's spring key 4 is housed at the circumferential outer surface of jar core 2.

2, by the described sucking type metering of claim 1 suction cup, it is characterized in that along axis the best symmetric two row's spring keies 4 being housed, and the spacing between each spring key 4 is identical with a spacing of arranging between the scale indicatrix 5 on tank body 1 circumferential outer surface at the circumferential outer surface of jar core 2.
