The present utility model provides a special injection device for injecting a radiopharmaceutical in a patient for a renal dynamic imaging examination, as shown in fig. 1, 2 and 3. The main structure comprises: the needle tube comprises a needle seat 1, a needle tube body 2, a conveying hose 4 and a heparin cap body 3, wherein a first accommodating cavity 11 is formed in the needle seat 1, the needle tube body 2 is fixedly connected to the needle seat 1, one end of the conveying hose 4 is arranged on the needle seat 1, and the heparin cap body 3 is in threaded connection with the other end of the conveying hose 4; wherein, needle tubing body 2, heparin cap body 3 and delivery hose 4 all switch on with first accommodation chamber 11, and delivery hose 4 length is less than 2cm. In some embodiments, the heparin cap body 3 may also be connected to the connection base by a snap-fit, interference fit connection, or the like. In other embodiments, the heparin cap body 3 is integrally formed with the hub 1.

It is known that the use of the indwelling needle can reduce pain of the child patient caused by repeated venipuncture and fear of injection, so that the anxiety of parents can be relieved, the workload of nurses can be relieved, and pain of the child patient can be reduced. In the nuclear medicine department of a hospital, a renal dynamic imaging examination is performed, a radioactive drug needs to be injected into the vein of a patient, the drug is required to be injected in a lump, the drug cannot be scattered, otherwise, the examination result is affected, the drug cannot be injected subcutaneously, and otherwise, the examination needs to be performed again on a daily basis. However, when some older patients do this examination, they typically do not cooperate with a physician to needle them for the injection of the radiopharmaceutical. If the drug is forcibly injected by injection, the injection process is easily disturbed or interrupted due to the reaction, so that the radioactive drug is scattered. Therefore, doctors often first place an indwelling needle on a patient of a smaller age, and then inject a radiopharmaceutical on a heparin cap on the indwelling needle when performing a renal dynamic imaging examination. However, the existing indwelling needle is provided with a longer hose (10 cm), the heparin cap and the steel needle are respectively arranged at two ends of the hose, and the radioactive drug is easily scattered due to an overlong drug delivery path, so that the dynamic kidney development examination effect is affected.

The length of the conveying hose 4 between the heparin cap body 3 and the needle seat 1 is set to be smaller than 2cm, and the length of the needle tube body 2 is shortened. So that the medicine injected from the heparin cap can be directly transported to the needle tube body 2 to enter the human body. The method directly reduces most of paths before the medicine injected from the heparin cap is delivered into the vein of the human body, and avoids the influence of the radioactive medicine on the examination result because the overlong delivery paths are easily broken up. When the patient is required to be examined by renal dynamic imaging, a doctor only needs to inject the radioactive drug into the first accommodating cavity 11 of the needle seat 1 from the heparin cap, and the drug directly reaches the needle tube body 2 after passing through the first accommodating cavity 11, so that the radioactive drug enters into the vein of the patient. Wherein, the conveying hose 4 can keep the soft connection between the heparin cap body 3 and the needle seat 1, and the medical staff only need to align the position and the angle of the movable heparin cap body 3 in the process of injecting the liquid medicine on the heparin cap body 3 without moving the needle seat 1. So that the whole process of injecting the liquid medicine does not disturb the patient.

Further, a connecting end seat 41 is arranged at one end of the conveying hose 4 far away from the needle seat 1, a thread 411 is arranged on the connecting end seat 41, and the heparin cap body 3 is in threaded connection with the connecting end seat 41 through the thread 411.

Further, a connecting ring part 31 is arranged at one end of the heparin cap body 3 near the conveying hose 4, and the connecting ring part 31 is in threaded connection with the needle seat 1 through threads 411. The heparin cap body 3 is fixed on the connection base by the connection ring portion 31.

Further, the outer side wall of the connecting ring portion 31 is provided with anti-slip lines 311. When the heparin cap is loosened, the friction force between the finger and the connecting ring part 31 can be increased through the anti-slip lines 311, so that slipping is prevented.

Further, as shown in fig. 3, the heparin cap body 3 is provided with a second accommodating cavity 32, the second accommodating cavity 32 extends along the direction of the conveying hose 4, the second accommodating cavity 32 is communicated with the first accommodating cavity 11, and a rubber plug 33 for leakage prevention is arranged in the second accommodating cavity 32. The rubber plug 33 is disposed at an end of the second accommodating cavity 32 away from the first accommodating cavity 11.

Further, as shown in fig. 3, an annular recess 34 is provided at the end of the heparin cap body 3 remote from the delivery hose 4. When a doctor inserts an injection liquid into the heparin cap, the needle for injecting the liquid is usually inserted from the bottom of the heparin cap body 3, i.e., the end provided with the rubber stopper 33. The annular concave table 34 is arranged at the bottom of the heparin cap of the needle falling, so that the sliding of the needle head of the liquid injection can be effectively prevented.

Further, the length of the needle tube body 2 is less than 4cm. It should be noted that, the length of the needle tube body 2 is shortened to effectively shorten the conveying path of the medicine to the vein of the human body, so as to avoid the influence of the radioactive medicine on the inspection result caused by the easy scattering of the overlong conveying path.

Further, the side wall of the needle holder 1 is provided with a needle wing 12. When the medical staff inserts the indwelling needle into the patient, the indwelling needle can be held by the needle wings 12, so that the needle tube body 2 is aligned with the vein of the patient for insertion. And the healthcare worker can adhesively fix the needle wings 12 through the medical sanitary adhesive tape, thereby securing the entire indwelling needle to the patient.

Further, the needle tube body 2 is detachably connected with a needle sleeve 5, and the needle sleeve 5 is used for coating the needle tube body 2. Before the indwelling needle is used, the needle tube body 2 is sleeved with a needle sleeve 5 so as to prevent the needle tube body 2 from injuring a doctor or a patient accidentally.

In summary, the present application provides a special injection device comprising: the needle stand 1 is provided with a needle stand, a first accommodating cavity 11 is formed in the needle seat 1; the needle tube body 2, the needle tube body 2 is fixedly connected to the needle seat 1; a conveying hose 4, wherein one end of the conveying hose 4 is arranged on the needle seat 1; the heparin cap body 3 is in threaded connection with the other end of the conveying hose 4; wherein, needle tubing body 2, heparin cap body 3 and delivery hose 4 all switch on with first accommodation chamber 11, and delivery hose 4 length is less than 2cm. The end of the conveying hose 4 far away from the needle seat 1 is provided with a connecting end seat 41, the connecting end seat 41 is provided with a thread 411, and the heparin cap body 3 is in threaded connection with the connecting end seat 41 through the thread 411. The length of the conveying hose 4 between the heparin cap body 3 and the needle seat 1 is set to be smaller than 2cm, and the length of the needle tube body 2 is shortened. Therefore, the conveying path of the medicine injected from the heparin cap in the kidney dynamic imaging examination is shortened, and the influence of the radioactive medicine on the examination result due to the fact that the overlong conveying path is easily broken up is avoided.
