Abstract
The utility model discloses an automatic blood-taking apparatus which is used for taking large quantity of blood at the aspects of blood treatment and the production of biological products and comprises a needle head, a needle tube and a disposable blood bag. A disposable blood-taking bag is arranged in a closed container. The container wall of the container is provided with two openings, wherein one opening is connected with a negative-pressure pump. A negative-pressure meter and a negative-pressure adjusting valve are installed between the negative-pressure pump and the container or on the container. The other opening is provided with a closed piston with a hole passage. A blood inlet tube of the disposable blood bag is connected with the needle tube through the hole passage. The utility model adopts a thinner needle head and reduces the venipuncture pain of a person which is taken. The blood automatically oscillates homogeneously and has magnetic polarization. The utility model relieves manual labour, has the advantages of time saving, labour saving, and simple and convenient operation, and enhances work efficiency.
Description
This utility model relates to a kind of blood-taking device, relates in particular to relatively large blood sampling blood-taking devices such as the blood supply of a kind of blood bank, haemodialysis.
As everyone knows, in clinical medicine blood experimentation, blood bank's blood supply.Aspects such as haemodialysis and biological product production all need to gather the blood source.For many years, medical profession is continued to use traditional " closed gravity blood collection method " always, promptly utilizes the gravity of blood self and venous pressure to make blood pass through syringe needle, needle tubing and flows into naturally in the blood bag (bottle); The blood collection needles of these class methods is thicker, is generally syringe needle 16～No. 22, brought bigger misery by blood sampling person, and blood sampling speed is slow, and is time-consuming.At present, having a small amount of unit to use vacuum blood collector, is 8820881 as application number, and name is called the utility model patent of " vacuum automatic blood sampler ", but this class hemostix only is applicable to the occasion of a small amount of blood samplings such as blood sampling.
The purpose of this utility model provides that a kind of syringe needle is thin, blood sampling speed is very fast and is applicable to the automatic blood-taking device of a large amount of blood sampling occasions.
In order to achieve the above object, the technical solution adopted in the utility model is, comprise syringe needle 1, needle tubing 2, disposable blood taking bag 3, described disposable blood taking bag 3 places an airtight container 4, a wherein wall of container 4 is arranged to pass in and out the movable end cover 8 of blood bag, end cap 8 and container 4 are placed in sealing ring 9 sealings on container 4 ports or the end cap 8, two openings are arranged on the wall of container 4, wherein an opening 10 connects a negative pressure pump 5, and vacuum table 6 and negative pressure control valve 7 are installed between negative pressure pump 5 and container 4 or on container 4; Another opening 11 places are provided with the packed-piston 13 in a road 12 with holes, and the blood vessel passing hole channel 12 that advances of disposable blood bag links to each other with needle tubing 2.Realization goal of the invention scheme preferably is that described packed-piston 13 is a tapered piston; Described sealing ring 11 places the groove 14 of negative-pressure container port wall; Described container 4 also links to each other with a vibration motor 15; Described container 4 adopts lucite to make, and enters the blood vessel place at blood taking bag the extremely relative Magnet of N, S is set.
The fixed form of Magnet 16 be can wall outer openings 11 places up and down or both sides one screw respectively is set, the Magnet that magnetic pole is relative is individually fixed on two screws during blood sampling; Also can with adhesive tape with Magnet be fixed on opening 11 places up and down or both sides.
When packed-piston 13 is set to cone, sealing effectiveness the best, negative-pressure container adopts lucite to make, lucite is transparent, is easy to observe, and vibration motor is connected with negative-pressure container, the vibration container makes anticoagulant and the abundant mixing of blood in the blood bag during operation, in order to avoid blood coagulation.This utility model is provided with the negative pressure of 0～0.32MPa in vacuum table and the negative pressure control valve assurance container 4, and blood can be flowed into smoothly, can not work the mischief to human body because of negative pressure is too big again.
Operation principle of the present utility model is that the negative pressure that negative pressure pump produces passes to the disposable blood bag, and the blood bag is expanded naturally, and internal pressure is lower, need not be than thick needle, and blood just flows into the blood bag smoothly.
Below in conjunction with accompanying drawing this utility model is further described
Fig. 1 fundamental diagram of the present utility model.
The structural representation of Fig. 2 this utility model negative-pressure container also is an embodiment.
The utility model is compared with existing blood-sampling method has useful effect:
1. 9～No. 12 fine needle head is adopted in venipuncture, has reduced gathered person's degree of tissue damage, Thereby reduced the venipuncture misery, shortened corresponding experiment and treatment course for the treatment of, be that again venipuncture creates Good condition.
2. it is fast to be lower negative pressure blood sampling speed in the blood bag.
3. the blood of gathering automatically vibration evenly reaches magnetic polarization, exempts artificial institute labor, and is time saving and energy saving; Operation Simple and convenient, reduced operator's labour intensity, improved operating efficiency.
