Abstract
The utility model discloses a blood collection injector and aims at providing the blood collection injector which can be operated by one hand and has the size suitable for that of a small-animal experiment. In order to solve the above technical problem, the blood collection injector adopts the following technical scheme that: the blood collection injector comprises a syringe needle, a syringe and a push rod, wherein a piston is arranged at the front end of the push rod, the piston is arranged in the syringe in a sliding way, the syringe needle is connected to the front end of the syringe, and a ring is arranged at the tail end of the push rod. Compared with the prior art, with the adoption of the blood collection injector, the one-hand control, injection and blood collection can be realized, and the blood collection injector has the characteristics of simple structure, one-hand control, strong practicability and convenience in operation.
Description
Technical field
This utility model relates to a kind of blood sampling syringe, especially a kind of toy blood sampling syringe.
Background technology
At present, the life sciences custom is made disease model with toy, and modal animal comprises mice, rat etc.Blood sampling or the small intravenously administrable of body surface are common research method.But because its technical difficulty is higher, success rate is very low in the practical operation, and final result is or has to toy is put to death blood sampling afterwards, perhaps is in stagnation owing to the administration operation failure causes whole experiment.These problems have increased the scientific research expenditure undoubtedly, have hindered carrying out smoothly of research.
Analyzing the reason of the problems referred to above, mainly is that animal often is in the struggle state and is difficult to fix because the small and weak blood vessel that causes of these toy builds is very thin, and the device that is used for toy injection or blood sampling at present is traditional clinically 1ml syringe.This syringe is made up of syringe needle, syringe, piston, push rod, pin medicated cap.Syringe needle is installed on the needle stand of syringe front end, and push rod one end connects the piston with the syringe coupling, and the other end is flaky base.This syringe is because volume and structure, and blood sampling or injection usually need both hands to cooperate, i.e. have on the other hand fixedly needle point and syringe of operator, another hands push belt piston pulling.So when the blood drawing injection of handling these toys, have to two people in addition more multiple person cooperational finish, and, can accidentally injure the operator because toy is struggled easily, exist big potential safety hazard.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of energy one-handed performance, and size is suitable for the blood sampling syringe of toy experiment.
For solving the problems of the technologies described above, this utility model adopts following technical scheme: a kind of blood sampling syringe comprises syringe needle, syringe and push rod, described push rod front end is provided with piston, described piston is slidingly arranged in the syringe, and the syringe front end connects syringe needle, and described push rod end also is provided with finger ring.
Finger ring described in the utility model is annulus, Fang Huan, rectangular ring or elliptical ring.
Finger ring described in the utility model is plastic hoop or becket.
Syringe described in the utility model indicates the volume scale.
Syringe needle described in the utility model is provided with the active pointer medicated cap outward.
This utility model compared with prior art can be realized singlehanded control, injection or blood sampling, has simple in structure, singlehanded control, practical and convenience operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model will be further described below in conjunction with drawings and Examples.
As shown in Figure 1, this utility model blood sampling syringe comprises syringe needle 1, syringe 2 and push rod 4, and wherein, push rod 4 front ends are provided with piston 3, and piston 3 is slidingly arranged in the syringe 2, and syringe 2 indicates volume scale 7; Syringe 2 front ends connect syringe needle 1, the syringe needle 1 outer active pointer medicated cap 5 that is provided with; Push rod 4 ends also are provided with finger ring 6.Finger ring 6 is plastic hoop or becket, is shaped as annulus, Fang Huan, rectangular ring or elliptical ring, and finger ring 6 big I appearance thumbs pass through, and after thumb passed finger ring, may command push rod-piston advanced in syringe or retreats.
The compositing characteristic of this utility model syringe needle 1, syringe 2, piston 3, push rod 4 is identical with conventional syringe.Push rod 4 ends have finger ring 6, and finger ring 6 diameter are passed through to good with the thumb that can hold ordinary person.Syringe 2 indicates volume scale 7 in addition, and size can be concealed in syringe in the ordinary person centre of the palm with the operator grasps fist and be advisable.During operation, the operator grasps syringe in the centre of the palm, and forefinger and middle finger are clamped the position that this utility model syringe needle 1 and syringe 2 join, and thumb passes finger ring 6, and thumb is exerted all one's strength, and control push rod 4 pulling pistons 3 retreat, and promptly reach the blood sampling purpose; If at first get the solution that to inject ready, syringe needle 1 is placed in this solution, thumb is exerted all one's strength, control push rod 4 pulling pistons 3 retreat, and promptly reach the purpose that extracts this solution, then, sought the suitable injection blood vessel of toy, thumb is exerted all one's strength, and control push rod 4 promotes piston 3 and advances, and promptly reaches the purpose of injection.The amount of injection solution and the amount of blood sampling can be read by volume scale 7.Have simple in structure, singlehanded control, practical and convenience operation.
What more than enumerate only is a specific embodiment of the present invention, and obviously, this utility model can also have many distortion.For example finger ring 6 can change to other material such as metal is made, and can change to square or rectangular etc. and can allow structure that thumb passes etc.This utility model removes and is used for animal blood sampling injection, also can be used for human clinical position, be used for inspections such as routine blood test as the blood that takes a morsel clinically, be used for PCR equimolecular inspection biology etc., also can be used for the field of micro-injections such as similar diabetes patient's insulin injection.
