Description

Gerontal patient's venipuncture auxiliary device

Technical field

The utility model relates to a kind of medical instrument more particularly to a kind of gerontal patient's venipuncture auxiliary devices.

Background technique

The skin of gerontal patient is loose, and when venipuncture is less susceptible to find the accurate location of vein.At present usually Two nurses are needed, are drawn with the skin for two hand handle patient of nurse to two opposite sides, so that skin is tightened, in this way, the position of vein is more To be clear and fixed, another nurse is punctured.

Utility model content

In view of the above problems, the utility model is directed to a kind of gerontal patient's venipuncture auxiliary device, can help The skin for tightening patient is helped, convenient for accurately finding vein and accurate puncture.

Gerontal patient's venipuncture auxiliary device of the utility model comprising: left clip, right clip；

Each clip includes upper half arm and lower half arm；The front end of upper half arm and lower half arm is formed together clamping opening, is used for The arm of patient is clamped in side and downside；Upper half arm and the rear end of lower half arm are rotationally combined together by shaft；Upper half arm Rear end be further formed upper handle, the rear end of lower half arm is further formed lower handle；It is formed in the middle part of upper handle and lower handle The upper end of opening, C-spring passes through the opening of upper handle and is arranged on the upside of upper half arm, and the lower end of C-spring passes through lower handle Opening and be arranged on the downside of lower half arm；

The shaft of left clip extends to the right, and its right end is provided with the first disk；

The shaft of right clip extends to the left, and its left end is provided with the second disk；

First disk and the second disk are superimposed together；

First disk and the second middle of the disc are combined together by bolt and nut；When bolt and nut is no tight dead, first Disk and the second disk can be rotated around bolt, so that the clamping opening of left clip and right clip is away from each other；Bolt and nut When tight dead, the first disk and the second disk cannot be rotated around bolt, and thus the mutual alignment of left clip and right clip is fixed.

Preferably, first disk is formed as rough surface with two surfaces of the contact of the second disk.

By gerontal patient's venipuncture auxiliary device of the utility model, can be made by separating left and right clip The skin-tightening of the arm of the patient clipped by left and right clip is conducive to correctly find venous locations and accurately be worn Thorn.

Specific embodiment

In the following, gerontal patient's venipuncture auxiliary device of the utility model is described in detail in conjunction with attached drawing.

Gerontal patient's venipuncture auxiliary device of the utility model comprising: left clip 10, right clip 20.

Each clip includes upper half arm and lower half arm；The front end of upper half arm and lower half arm is formed together clamping opening, is used for The arm 40 of patient is clamped in side and downside；Upper half arm and the rear end of lower half arm are rotationally combined together by shaft 12,22； The rear end of upper half arm is further formed upper handle, and the rear end of lower half arm is further formed lower handle；In the middle part of upper handle and lower handle It is formed with opening, the upper end of C-spring 11,21 passes through the opening of upper handle and is arranged on the upside of upper half arm, C-spring 11,21 Lower end pass through lower handle opening and be arranged on the downside of lower half arm, thus C-spring provided for clip make its closure elastic force.

The shaft 12 of left clip 10 extends to the right, and its right end is provided with the first disk 13.The shaft 22 of right clip 20 Extend to the left, and its left end is provided with the second disk 23.

First disk 13 and the second disk 23 are superimposed together；Pass through bolt 31 among first disk 13 and the second disk 23 Nut 32 is combined together；When 31 nut 32 of bolt is no tight dead, the first disk 13 and the second 23 disks of circle can be carried out around bolt 31 Rotation, so that the clamping opening of left clip 10 and right clip 20 is away from each other；When 31 nut 32 of bolt is tight dead, 13 He of the first disk Second disk 23 cannot be rotated around bolt 31, and thus the mutual alignment of left clip 10 and right clip 20 is fixed.

First disk 13 is formed as rough surface with two surfaces of the contact of the second disk 23, to fasten upper Shi Zengjia Frictional force each other.

In use, then rotating clip to two sides respectively as shown in fig. 7, clip clip, e.g. pass through a hand difference It breaks on the left of left clip and on the right side of right clip the distance between handle is become smaller, in this way, two clamping opening will get each other more It opens, the skin between two clamping opening will be tauted, and then fasten bolt and nut, the angle between two clips is kept, into Row disinfection and puncture.

Claims

1. a kind of gerontal patient's venipuncture auxiliary device, characterized by comprising: left clip, right clip；
