Abstract

The utility model relates to a vacuum cupping jar, comprising a jar body (7) and a one-way air valve (4) on the top of the jar body. The utility model is characterized in that the outer wall of an inner convex column (3) which is connected with the jar body (7) and is extended toward an inner cavity of the jar body is sheathed with a sleeve (2), and the interior of the sleeve (2) is provided with a spring (6). The lower end of the spring (6) is connected with a contact (9) which has the conical lower end, the cone point of the contact (9) faces downwards, and the contact (9) and the inner wall of the sleeve (2) have a sliding connection. The contact can ensure that the force pressing on the skin is basically invariant. The utility model has the advantages of high safety and comfortable and convenient use.

Description

Vacuum cupping

This utility model relates to a kind of traditional medical apparatus, particularly a kind of cup.

In the prior art, vacuum cupping comprises tank body, be arranged at the pore at tank body top and the Non-return air valve in the pore, and a jar intravital air can be extracted after putting the evacuation rifle in the top of described tank body, makes and causes the skin surface that is adsorbed on human body after the negative pressure in the tank body.Be provided with conical contact tip in the inner chamber of the cup that has, the awl spine of this contact is at the place, acupuncture point of human body surface, but because jar intravital vacuum difference, therefore skin surface is also inequality at the intravital height of jar, the constant strength difference that causes stabbing skin of described awl cusp height, severe patient causes skin to puncture.

The purpose of this utility model is to provide a kind of point of boring to be pressed in the vacuum cupping that the strength of skin surface remains unchanged substantially.

The technical solution of the utility model is: a kind of vacuum cupping, comprise lower opening tank body, be arranged at the tank body top vertical pore, be arranged at the Non-return air valve in the described pore, the interior projection of the outside of described pore for being connected with tank body and extending to tank inner chamber; Be with sleeve on the outer wall of projection in described, be provided with spring in the described sleeve, the lower end of described spring and lower end are that the contact of taper is connected, the awl point of described contact down, described contact and telescopic inwall are slidingly connected.

This utility model compared with prior art has following advantage:

Because the top of contact is provided with spring, can length travel take place according to the suffered pressure of contact, so this contact can keep the strength that is pressed on the skin constant substantially, has safe in utilization, comfortable, advantage easily.

The utility model will be further described below in conjunction with drawings and Examples:

Accompanying drawing is a structure cutaway view of the present utility model; Wherein:

[1]. positive stop; [2]. sleeve; [3]. interior projection; [4]. Non-return air valve; [5]. pore; [6]. spring; [7]. tank body; [8]. the contact cover; [9]. contact;

Embodiment: referring to accompanying drawing, a kind of vacuum cupping, comprise lower opening tank body [7], be arranged at tank body [7] top vertical pore [5], be arranged at the Non-return air valve [4] in the described pore [5], the interior projection [3] of the outside of described pore [5] for being connected with tank body [7] and extending to tank inner chamber; Be with sleeve [2] on the outer wall of projection [3] in described, be provided with spring [6] in the described sleeve [2], the upper end of described spring [6] is against the lower end of interior projection [3], the lower end of described spring [6] and lower end are that the contact [9] of taper is connected, the awl point of described contact [9] down, the inwall of described contact [9] and sleeve [2] is slidingly connected.In order to control the extreme position that moves down of contact [9], the upper outer circumferential surface of described contact [9] is provided with annular positive stop [1], the excircle diameter of this positive stop [1] is greater than the circle diameter of contact [9], and this positive stop [1] is positioned at the top at the place that is slidingly connected of sleeve [2] and contact [9].

Claims
