Description
Technical Field
The utility model relates to the technical field of medical supplies, in particular to a high-pressure syringe pre-pumping physiological saline switch type needle.
Background
During CT enhanced scanning, the high-pressure injector has high injection pressure (7 ml/s at the fastest) and high speed, and the contrast agent has high viscosity and high osmotic pressure, so that the contrast agent is easy to exosmose. The extravasation of the contrast agent is one of the serious complications of CT enhancement scanning, such as improper treatment, often causes tissue necrosis to affect the form and function of limbs, brings pain to patients and causes medical disputes. The normal saline is pre-pumped during high-pressure injection, so that whether the venous access is unobstructed or not can be checked, whether the blood vessel can bear high-pressure injection or not is judged, high-pressure injection of the contrast agent can be carried out after determination, and the contrast agent can be effectively prevented from being extravasated. After the contrast agent is administered, part of the normal saline is injected again under high pressure, so that the contrast agent can fully reach the interest area of the examined part, and the image development effect is improved. The risk of extravasation of the contrast agent can be reduced by pre-pumping physiological saline high-pressure injection during CT enhanced scanning, and the image quality can be improved at the same time.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings.
As shown in fig. 1, the high-pressure syringe pre-pumping physiological saline switch type needle head disclosed by the utility model comprises a puncture tube 1 and a connecting tube 6, wherein the front end of the puncture tube 1 is provided with a conical tip 2, the rear end of the puncture tube 1 is connected with the front end of the connecting tube 6, the conical tip 2 is provided with a strip-shaped liquid through port 3, the liquid through port 3 is parallel to a bus of the conical tip 2, and at least two liquid through ports 3 are arranged at intervals around the conical tip 2; preferably, there are three ports 3. The puncture tube 1 gradually increases in diameter from front to back, and is convenient to insert.
The liquid through port 3, the puncture tube 1 and the connecting tube 6 are communicated with each other; the connecting pipe 6 is provided with the switch 4, and the switch 4 can play a role in cutting off liquid and is convenient to close at any time. The rear end of the connecting pipe 6 is provided with a threaded interface 7. The conical tip 2, the puncture tube 1 and the connecting tube 6 are manufactured in one piece. A limiting plate 5 is arranged at the joint of the puncture tube 1 and the connecting tube 6, and the limiting plate 5 and the puncture tube 1 are integrally manufactured. When in use, the finger is also convenient to abut against the limiting plate 5 to insert the conical tip 2 into the soft infusion bag.
As shown in figure 2, when in use, the normal saline soft bag 9 is hung on the transfusion bracket 8, the conical tip 2 of the puncture tube 1 is punctured into the normal saline soft bag 9, then the threaded interface 7 is in threaded connection with the liquid through port of the high-pressure syringe 10 of the injection pump 11, and then the switch 4 and the injection pump 11 are turned on. Because the medical high-pressure injector 10 has various specifications, the threaded interface 7 can be correspondingly designed into various specifications, and the matched specification can be selected when the medical high-pressure injector is used. After the high-pressure syringe 10 sucks a proper amount of liquid medicine, the switch 4 is closed, and the high-pressure syringe 10 and the threaded connector 7 are unscrewed. Because the puncture tube 1 is not contacted with the human body, the puncture tube is continuously kept on the normal saline soft bag 9 for the next use. Due to the addition of the switch 4 and the threaded interface 7, the soft normal saline bag 9 can be hung on the infusion support 8 without worry, and the soft normal saline bag 9 does not need to stand above the high-pressure injector 10 by hands.
The utility model has simple structure and convenient use; a passage is conveniently established between the normal saline soft bag and the high-pressure injector 10, and the opening and the closing can be controlled at any time; the normal saline soft bag 9 can be used for a plurality of times after being inserted once, so that the operation time can be saved, the working efficiency can be improved, and the labor intensity of medical personnel can be reduced.
Of course, the present invention can be embodied in many other forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be made by one skilled in the art without departing from the spirit or essential attributes thereof, and that such changes and modifications are intended to be included within the scope of the appended claims.
