Problems solved by technology

[0003] The common sampling method at this stage is usually to cut the pigtail of the blood bag with scissors, release the blood in the pigtail of the blood bag, and then proceed to the next step. However, since the pigtail is sampled directly with scissors, it is very easy to Contaminate the blood and cause errors in the test results, which may cause problem blood to be sent to the patient, causing irreparable huge losses
[0004] Due to the manual operation during the whole process, it is easy to pierce the hand, resulting in serious consequences for the operator to be infected by the problem blood

Embodiment 1

[0041] Embodiment 1: as Figure 1-6 As shown, a cutting device for blood bag pigtails includes a base 1, the top of the base 1 is integrally connected with an inlet 2, the bottom of the base 1 is integrally connected with an outlet 3 coaxially arranged with the inlet 2, and the inside of the inlet 2 is A pipeline channel 7 is opened on the shaft, and a liquid flow channel 8 is coaxially opened inside the outlet 3. A cavity 6 is opened between the pipeline channel 7 and the liquid flow channel 8 and inside the base 1. The pipeline channel 7 is connected to the liquid flow channel 8. The flow channel 8 communicates with the cavity 6 , and a cutting assembly 11 is detachably installed on one side outside the base 1 .

[0042] The cross-sectional shape of the inlet 2 is elliptical, and the inlet 2 extends a certain distance along the axis direction of the end away from the base 1 .

[0043] The pipeline channel 7 is provided with a hypotenuse inclined at a certain angle at the en...

Embodiment 2

[0073] Embodiment 2: as Figure 10 As shown, this embodiment is an improvement on a cutting device for blood bag pigtails in embodiment 1, which includes all the technical features of a cutting device for blood bag pigtails in the above embodiment 1 , the improvement lies in the overall structure of the cutting assembly 11.

[0074] A side of the cutting assembly 11 close to the base 1 is provided with a knife groove 14 for installing a blade 16 , and the knife groove 14 is obliquely provided on the cutting assembly 11 at a certain angle.

[0075] The base 1 is provided with a guide groove 10 matching with the blade 16, and the guide groove 10 is obliquely opened on the base 1 at a certain angle.

[0076] The side of the base 1 close to the cutting assembly 11 is fixedly provided with a sealing cotton 5 for sealing the guide groove 10 , and a gap matching the shape of the blade 16 is opened on the sealing cotton 5 , and the blade 16 can pass through the gap.

Abstract

The invention discloses a cutting device for a blood bag braid. The cutting device comprises a base, wherein the top of the base is integrally connected with an inlet, the bottom of the base is integrally connected with an outlet which is coaxial with the inlet, a pipeline channel is coaxially formed in the inlet, a liquid flow channel is coaxially formed in the outlet, a cavity is formed between the pipeline channel and the liquid flow channel and located in the base, the pipeline channel communicates with the liquid flow channel through the cavity, and a cutting assembly is detachably installed on one side of the outer portion of the base. By the adoption of the technical scheme, the cutting device is simple in structure and ingenious in concept, blood pollution is avoided in the using process, sealing cotton can ensure that blood does not flow out through a guide groove after the blood bag braid is cut off by a blade, the sealing performance of the guide groove is improved, the serious consequence of blood infection caused by the fact that the blood is stained on the hand of an operator is avoided, and higher safety is ensured through disposable use.

Description

technical field [0001] The invention relates to a cutting device, in particular to a cutting device for blood bag pigtails. Background technique [0002] Voluntary blood donation is a matter that benefits the country and the people. Since the implementation of the "Law of the People's Republic of China on Voluntary Blood Donation", it has achieved great development. The barcode of the sample test tube is exactly the same as the barcode of the blood bag. At the same time, it is required to use one-handed operation when retaining the sample to avoid biological damage, and the relevant information of blood collection can be traced. [0003] The common sampling method at this stage is usually to cut the pigtail of the blood bag with scissors, release the blood in the pigtail of the blood bag, and then proceed to the next step. However, since the pigtail is sampled directly with scissors, it is very easy to Contamination of the blood, resulting in errors in test results, may cau...
