Abstract
The utility model relates to a rat continuous hemostix which comprises a needle head (1), a collecting tube (2) and a connecting tube (3) which is used for connecting the connecting needle head (1) and the collecting tube (2). The rat continuous hemostix is characterized in that a rubber separating board (4) is arranged in the collecting tube (2), holes are formed in the rubber separating board (4), a negative pressure blood collecting tube (5) is installed on each hole in a sleeved mode, a rubber cover (6) is arranged on each negative pressure blood collecting tube (5), and a crossed cutting incision (7) is arranged on each rubber cover (6). According to the rat continuous hemostix, the collecting tube is improved, the negative pressure collecting tubes (5) are arranged in the collecting tube (2), blood collecting in a sealed mode is achieved, and probability that blood is polluted is reduced. When the rat continuous hemostix is used, the blood can enter a corresponding negative pressure collecting tube (5) by squeezing of the crossed cutting incisions (7). In a blood collecting process, pollution on the surroundings due to external flow of the blood cannot be caused, the rat continuous hemostix is clean and healthy, simple in operation process and convenient to use.
Description
Technical field
The utility model relates to the animal blood taking apparatus, what be specifically related to is a kind of rat continuous blood sampler.
Background technology
After some drugs or food are developed, need to carry out animal experiment, investigate analysis according to result of the test, and some correlation properties such as its safety are done comprehensive explanation.At last, could might carry out the batch production stage.
At present, the animal experiment majority behind the medicine or food through the doses of feeding, regularly gathers blood take muroid as main in earlier stage, carries out follow-up relevant chemical examination and detects research.Rat is different from mice, and blood volume is relatively more, and acquisition method in the past is the syringe needle that uses with one section syringe, another termination collection tube of syringe, after a collection tube is filled, change again another collection tube, sometimes required according to test, need to gather the blood of three or four pipe collection tubes, but can not take a blood sample continuously again, again and again changing collection tube one is to have strengthened the contaminated probability of blood, the 2nd, when changing, also cause easily blood to flow on operating board or the ground, cause the waste of blood.
Therefore, based on the problem that above-mentioned prior art exists, urgent need will provide a kind of can reduce blood contamination, and the device that can take a blood sample continuously.
The utility model content
Goal of the invention of the present utility model is to provide a kind of rat continuous blood sampler for the problems referred to above, and be used for solving needs at present again and again to change that the blood that exists when collection tube is taken a blood sample easily pollutes and the problem of the problem that can not take a blood sample continuously.
This utility model is achieved through the following technical solutions: the rat continuous blood sampler comprises the connection tube of syringe needle, collection tube and connecting needle and collection tube, described collection tube is built-in with rubber separator, have the hole on the rubber separator, be set with negative pressure blood-taking tube on the hole, negative pressure blood-taking tube is provided with serum cap, is provided with cross type cut on the serum cap.
As further improvement of the utility model, described negative pressure blood-taking tube is 3～5 tubules placed side by side.
Adopt the good effect of technique scheme:
1, this utility model improves collection tube, is provided with negative pressure and gathers tubule in collection tube, has realized the sealing blood sampling, has reduced the contaminated probability of blood;
When 2, this utility model uses, by the extruding cross type cut, make blood flow into corresponding negative pressure and gather in the tubule;
3, in this utility model blood collection procedure, can not pollute surrounding because of blood outflow, clean hygiene more, whole operating process is simple, easy to use.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the plan structure sketch map of serum cap in this utility model.
Among the figure: 1 syringe needle, 2 collection tubes, 3 connection tubes, 4 rubber separators, 5 negative pressure blood-taking tubes, 6 serum caps, 7 cross type cuts.
The specific embodiment
In order to be illustrated more clearly in the technical solution of the utility model, below in conjunction with concrete diagram, further set forth content of the present utility model.
As shown in Figure 1, the rat continuous blood sampler comprises the connection tube 3 of syringe needle 1, collection tube 2 and connecting needle 1 and collection tube 2.Difference of the present utility model is: collection tube 2 inside arrange a rubber separator 4, and offer the hole at rubber separator 4.Be set with negative pressure blood-taking tube 5 on the hole, the negative pressure value in the negative pressure blood-taking tube 5 arrange according to the size of warp in the pipe, just maintain an equal level with 3/5ths o'clock pressure of blood inflow pipe volume and are advisable.Negative pressure blood-taking tube 5 is provided with serum cap 6, is provided with cross type cut 7 on the serum cap 6.During use, can by extruding cross type cut 7, flow into the passage of negative pressure blood-taking tube 5 to open blood.
In addition, for ease of using, improve the simple and easy degree of operation, also negative pressure blood-taking tube 5 can be set to 3～5 tubules placed side by side.Like this, whole collection tube is the structure of a flat, and is easy to use, deposit.
During use, first according to conventional method, rat is fixed; After fixing, syringe needle is inserted in the blood vessel, be generally and insert the tail vein, after the insertion, by the extruding serum cap, blood can automatic photograph flows in the negative pressure blood-taking tube, when overpressure and endovascular pressure are fair, loose one's grip, no longer push serum cap, at this moment, serum cap can restore automatically, cover on negative pressure blood-taking tube, prevent that blood from flowing out.
In case of necessity, can cross one assign to two minutes after, push again another negative pressure blood-taking tube, purpose is in order to prevent that rat is owing to a large amount of blood samplings in the short time cause death.
Claims (2)
1. rat continuous blood sampler, the connection tube (3) that comprises syringe needle (1), collection tube (2) and connecting needle (1) and collection tube (2), it is characterized in that: described collection tube (2) is built-in with rubber separator (4), rubber separator has the hole on (4), be set with negative pressure blood-taking tube (5) on the hole, negative pressure blood-taking tube (5) is provided with serum cap (6), is provided with cross type cut (7) on the serum cap (6).
