Abstract

The utility model relates to a negative pressure sucking needle, which comprises a balloon (1), a tank body (5) and a conical needle tip (8). The needle tip (8) is downward and is positioned on the opening part of the tank body (5). The utility model is characterized in that the inner part of an inner chamber of the tank body (5) is provided with a hollow post body (9) connected with the tank body. The lower opening part of the inner chamber (10) of the post body of the hollow post body (9) is provided with the needle tip (8). The needle tip (8) is glidingly connected with the inner wall of the inner chamber (10) of the post body. The inner part of the inner chamber (10) of the post body is provided with a spring (6). The lower end of the spring (6) contacts the upper end part of the needle tip (8). The utility model has an ill treating function when the needle tip is pressed on an acupoint.

Description

The negative pressure suction spindle

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

In the prior art, the negative pressure suction spindle, the taper needle point of the inside that comprise balloon, the tank body that is connected with the infraoral of described balloon, is arranged at described tank body, described needle point are down and be positioned at oral area, the inner chamber of described balloon and the intracavity inter-connection of described tank body of tank body.The tank body oral area is pressed on the acupuncture point of skin, described balloon is pinched and is made after flat tank body form negative pressure to inhale on skin, is pressed in by needle point to reach the purpose of curing the disease on the skin.Because the position relative fixed of needle point is therefore big in the power of the high hour hands spine of the intravital negative pressure degree of jar on skin, at tank body because gas leakage and when suction diminished gradually, the power of needle point thorn on skin diminished, and reduces therapeutic effect.

The purpose of this utility model is to provide the negative pressure suction spindle of a kind of needle point to the pressure constant of skin.

The technical solution of the utility model is: a kind of negative pressure suction spindle, the taper needle point of the inside that comprise balloon, the tank body that is connected with the infraoral of described balloon, is arranged at described tank body, described needle point down and be positioned at the oral area of tank body, the inner chamber of described balloon and the intracavity inter-connection of described tank body; Be provided with the hollow cylinder that is connected with tank body in the inner chamber of described tank body, the infraoral of the cylinder intracavity of described hollow cylinder is provided with needle point, the inwall of described needle point and described cylinder intracavity is slidingly connected, be provided with spring in the described cylinder intracavity, the lower end of this spring is against the upper end of described needle point.

This utility model compared with prior art has following advantage:

Because can sliding and be offseted by spring, needle point makes it to have elasticity in cylinder intracavity, needle point upwards shrank under top on the skin when therefore negative pressure was big in jar, and needle point still is pressed on the skin under the pressing down of spring when negative pressure diminishes in jar, makes skin be subjected to a substantially invariable needle tip pressure.Because the difference of body part also can make needle point keep a constant force to be pressed on the skin.

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