Problems solved by technology

[0003] In order to ensure the occurrence of cross-infection, most hospitals currently use finger blood drawing to collect blood samples, and finger blood drawing mainly uses disposable medical equipment for blood collection, which will generate a large amount of medical waste and bring The increase in expenditure is due to the fact that it is difficult to fully disinfect blood needles
[0004] At the same time, this blood drawing method also has some problems in the blood drawing work, such as needing two different operation steps for puncturing and collecting, which is inefficient, and when using a disposable blood collection needle for blood drawing, the medical staff must communicate with the waiting The possibility of cross-infection cannot be completely avoided due to the contact between the samplers

Embodiment 1

[0023] see Figure 1-4 , a finger-fixed blood sampler, comprising an operating frame 1 and a reusable needle holder 2 connected separately to the operating frame 1, the operating frame 1 is in the shape of a "mouth", and the lower half of the operating frame 1 is connected to the front and rear sides The fixed cavity 4, the reusable needle holder 2 is slidably installed on the top of the fixed cavity 4, the inner side of the upper half frame of the operation frame 1 is provided with a push channel 11, and the push column 6 is provided in the push channel 11 to be slidably connected to it. The reusable needle holder 2 is provided with a puncture needle 23; when using the device to collect blood samples, put your finger into the fixed cavity 4, and apply downward pressure to the pressure column 6, and the pressure column pushes the reusable needle downward The seat 2 makes the pricking needle 23 contact with the finger to puncture the finger, and the device can be fixed on the t...

Embodiment 2

[0028] The difference from Embodiment 1 is that the lower part of the fixed cavity 4 is provided with a supporting plate 3 slidingly connected to the inner surface of the fixed cavity 4, the top surface of the supporting plate 3 is in a downwardly concave arc shape, and the bottom of the supporting plate 3 and the fixed A plurality of spring rods 31 are provided between the inner bottom surfaces of the cavity 4 for support. Fingers are placed on the supporting plate 3, and the pressure is relieved by the spring rods 31, thereby being able to adapt to the blood collection work performed on fingers of different thicknesses.

Embodiment 3

[0030] The difference from Embodiment 1 is that, if the pressure column 6 can synchronously drive the reusable needle holder 2 to move synchronously, the bottom surface of the pressure column 6 and the top surface of the seat body 21 are provided with matching Velcro, so that When the reusable needle holder 2 is installed, the reusable needle holder 2 and the bottom surface of the pressure column 6 can be bonded, so that the pressure column 6 can synchronously drive the reusable needle holder 2 to move.

Abstract

The invention discloses a finger fixing type blood sampler. The blood sampler comprises an operation frame and a multiplexing needle file connected with the operation frame in a split manner, whereinthe operation frame is square, and the lower half part of the operation frame is provided with a fixing cavity with cut-through front and rear sides, the multiplexing needle file is mounted on the inner top of the fixing cavity in a sliding manner, a push channel is formed at the inner side of the upper half framework of the operation frame, a compression column in sliding connection with the pushchannel is arranged in the push channel, and a puncturing needle is arranged in the multiplexing needle file. The device is ingenious in structure, the multiplexing needle file is convenient to detach, the reuse after a plurality of times of disinfection is well realized, thus the expenditure is saved, meanwhile, through the match among a first sliding chute cavity, a second sliding chute cavity,the puncturing needle and a connecting post, the continuous work including puncturing and blood sampling can be continuously completed during one-time operation, compared with the conventional fingerblood sampler, the blood sampler provided by the invention has the advantages the collection efficiency is greatly improved, and meanwhile, the direct contact between a medical worker and a person tobe subjected to blood sampling can be avoided, so that the probability of cross infection is reduced.

Description

technical field [0001] The invention relates to a medical device, in particular to a finger-fixed blood sampler. Background technique [0002] Now doing a physical examination is inseparable from the blood drawing part. Many health checks rely on blood analysis to check, therefore, blood drawing is an important part of health check-up. [0003] In order to ensure the occurrence of cross-infection, most hospitals currently use finger blood drawing to collect blood samples, and finger blood drawing mainly uses disposable medical equipment for blood collection, which will generate a large amount of medical waste and bring The reason for the increase in expenditure is that it is difficult to thoroughly sterilize blood-drawing needles. [0004] At the same time, this blood drawing method also has some problems in the blood drawing work, such as needing two different operation steps for puncturing and collecting, which is inefficient, and when using a disposable blood collection...
