Description
Technical field
This utility model belongs to medical experiment equipment technical field, is specifically related to a kind of Novel experimental tail vein injection device.
Background technology
Current experimental rat, through tail intravenously administrable, uses the scalp acupuncture of disposable medical 1ml syringe or connection syringe.But the tail vein diameter of experimental rat is thin and position is comparatively dark, and experimenter's venipuncture difficulty is large, and intravenously administrable success rate is low, virtually increases experiment difficulty.Meanwhile, when using ordinary syringe, operator not easily observes the blood back phenomenon after venipuncture success, if pumpback by force, has blood to enter syringe, pollutes medicinal liquid, cannot administration again.And the syringe of union joint sword-shaped needle exists medicinal liquid attached wall when injecting in use, cause quantitative error; If use normal saline or other solvent washing pipes, then can strengthen administration total measurement (volume), may cause laboratory animal heart failure, and need assistant to coordinate when changing syringe, operation comparatively bothers, and may bring bubble into causes air embolism simultaneously.
Utility model content
The purpose of this utility model be solve experimental rat through tail intravenously administrable time tail success rate of venous puncture low, syringe inner liquid medicine pollute and run off, washing pipe administration volume is large and change syringe time air enter the problem of connection tube and a kind of experimental mouse tail vein injection device be provided.
For solving the problems of the technologies described above, the technical scheme that this utility model adopts is: a kind of Novel experimental tail vein injection device, comprise syringe needle (1), syringe (7), wherein: it also comprises needle handle (2), connection tube (3), joint (4), caisson (6); One end of described syringe needle (1) communicates with one end of connection tube (3), described caisson (6) is arranged between connection tube (3) and syringe (7), and be positioned at joint (4), described caisson communicates with syringe (7) and connection tube (3), and described needle handle (2) is arranged on the junction of syringe needle (1) and connection tube (3); Described joint (4) is arranged between connection tube (3) and syringe (7).
Anti-skidding groove (5) is also provided with in described joint (4) outer rim.
Described caisson (6) is cryptomere shape.
Described connection tube (3) is transparent hose.
Compared with background technology, this utility model adopts technique scheme, has the following advantages: the first, is provided with transparent hose between syringe needle and syringe, and puncturing is successfully blood back phenomenon in visible flexible pipe, avoids inserting needle to cross dark or excessively shallow, improves puncture success rate; The second, during pumpback syringe, blood can not enter syringe at once, and animal blood can be avoided to pollute syringe inner liquid medicine; 3rd, use simple and easy needle handle to operate syringe needle puncture, simple and convenient; 4th, brief flexible pipe is set, reduces the attached wall loss of medicine; 5th, joint is provided with anti-skidding dentate margin, can realize one-handed performance, alleviates experimenter's burden; 6th, because caisson can hold a certain amount of gas, enter if any air during replacing syringe, can be stored in temporarily and prevent air embolism herein; 7th, this utility model structure is simple, with low cost.Solve operator not easily observe venipuncture success after blood back phenomenon, during pumpback, blood enters syringe and pollutes the problem of medicinal liquid by force.Meanwhile, also solve the attached wall of medicinal liquid and cause quantitative error, strengthen administration total measurement (volume) during washing pipe and cause laboratory animal heart failure, and need assistant to coordinate when changing syringe and the problem that bubble causes air embolism may be brought into.Therefore, it is simple that this utility model has structure, accurately can puncture, easily observe blood back phenomenon, and anti-return blood pollutes medicinal liquid, reduces the attached wall loss of medicinal liquid, and when preventing operation, air enters flexible pipe, can the advantage such as one man operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of Novel experimental tail vein injection of the present embodiment device, a kind of Novel experimental tail vein injection device, comprises syringe needle 1, syringe 7, wherein: it also comprises needle handle 2, connection tube 3, joint 4, caisson 6; One end of described syringe needle 1 communicates with one end of connection tube 3, described caisson 6 is arranged between connection tube 3 and syringe 7, and be positioned at joint 4, described caisson communicates with syringe 7 and connection tube 3, described needle handle 2 is arranged on the junction of syringe needle 1 and connection tube 3; Described joint 4 is arranged between connection tube 3 and syringe 7.
Anti-skidding groove 5 is also provided with in described joint 4 outer rim.
Described caisson 6 is cryptomere shape.
Described connection tube 3 is transparent hose.
Syringe in use, is extracted normal saline or other solvents by this utility model, connects top connection, and the air in emptying flexible pipe and syringe needle, just can operate.
Concrete operation step of the present utility model is as follows:
The first step: the tail fixing experimental rat, partial hot compressing or hot-water soak a moment, to make tail venectasia;
Second step: syringe is extracted normal saline or other solvents, connects top connection, the air in emptying flexible pipe and syringe needle, in order to puncture.Separately get a syringe and extract medicinal liquid, for subsequent use;
3rd step: prepare site of puncture by alcohol wipe, hand-held needle handle, to become the angle of 30 ° slowly to proximal part inserting needle with tail, until flexible pipe is shown in that blood back stops puncture, advances a little with tail vein parallel direction; Pumpback syringe gently, sees if there is more blood and enters flexible pipe, if it is confirms that syringe needle is at tail intravenous, punctures successfully, fixing needle handle;
4th step: another hands pinches joint and pulls out outward, can remove the syringe of dress normal saline or other solvents, then loads onto the syringe containing medicinal liquid, carries out administration;
5th step: after completing the drug injection of given dose, same method removes Sheng medical fluid injector, connects the syringe containing normal saline or other solvents, carries out washing pipe.
6th step: extract syringe needle after completing, hemostasis by compression.
