Abstract

The utility model relates to a disposable aseptic blood taking needle, characterized in that a needle body [2] is fixed in the inner of a needle handle [1]; a needle head [4]of the needle body, which is arranged on one end of the needle handle [1] comes out and is inserted into a needle cap [5]; the needle cap [5]and the needle handle [1]are connected by packing the neck [4] of the needle head [4]. The utility model can control the tear of the depth and area of the skin and can ensure the one-time use.

Description

Disposable use sterile blood sampling pin

This utility model relates to a kind of medical blood-sampling needle.

In the prior art, skin blood sampling sampling is generally poked with syringe needle by the chemical examination department in the hospital, because the degree of depth that protrudes into of syringe needle is difficult for grasping, so make patient's the wound degree that is subjected to have nothing in common with each other, the medical worker of blood sampling need have more experience and technical ability.

The purpose of this utility model is to provide a kind of degree of depth and essentially identical disposable use sterile blood sampling pin of area that can make syringe needle poke skin.

The technical solution of the utility model is: needle body is fixed in the inside of needle handle, and the syringe needle that needle body exposes needle handle one end is inserted in the pin medicated cap, and the pin neck by the parcel syringe needle between described pin medicated cap and the needle handle is connected.

This utility model compared with prior art has following advantage:

(1). turn the pin medicated cap during use, make pin neck fracture, then take down the certain syringe needle of exposed length behind the pin medicated cap, the length restriction of this syringe needle protrude into the degree of depth and the wound area of skin, can not cross the dark or shallow excessively skin that protrudes into, can alleviate patient's pain and can collect sufficient sample of blood yet.

(2). the pin medicated cap with can not connect once more after needle handle separates, so guaranteed the disposable use of this utility model, the situation of cross infection can not appear.

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

Accompanying drawing 1 is a structural front view of the present utility model;

Accompanying drawing 2 is the structure chart of syringe needle part; Wherein:

[1]. needle handle; [2]. needle body; [3] pin neck; [4] syringe needle; [5]. the pin medicated cap; [6]. the needle point chamfering;

Embodiment: referring to accompanying drawing 1 and accompanying drawing 2, the needle body that stainless steel material is made [2] is fixed in the inside of the needle handle [1] that plastic material makes, the syringe needle [4] that needle body [2] exposes needle handle [1] one end is inserted in the oblate pin medicated cap [5], pin neck [4] by parcel syringe needle [4] between described pin medicated cap [5] and the needle handle [1] is connected, the length of described pin neck [3] is 0.5～0.1 millimeter, and the wall thickness of pin neck [3] is 0.5～0.05 millimeter.In order to make patient's blood sampling wound area less, the both sides, inclined-plane of described syringe needle [4] are provided with needle point chamfering [6], make that syringe needle [4] is sharper.Described pin medicated cap [5] is flat, and purpose is to be convenient to turn pin medicated cap [5].
