Description

A New Spiral Quantitative Anti-off Syringe

technical field

The utility model relates to the technical field of medical instruments, in particular to a novel spiral quantitative anti-off syringe.

Background technique

In hospitals, due to the needs of diagnosis and treatment of diseases, medical staff often have to draw blood, ascites, pleural effusion, pericardial effusion, and puncture and aspirate cysts, abscesses, and spinal cords for patients. The suction work here is all done by the syringe. The working principle of syringe suction is to use the piston rod inside the syringe to generate negative pressure in the cavity at the front end of the syringe tube, so that the liquid or gas is sucked into the syringe tube. When using a common syringe for suction, the operator must hold the syringe tube with one hand and pull the piston rod back with the other hand. When a negative pressure is formed in the front cavity of the syringe tube and the aspirated material is gradually sucked into the syringe tube, the piston rod is also sucked. In order to ensure that the piston rod will not be sucked back, the operator must always pull the piston rod hard. When continuously sucking a large amount of liquid (such as ascites and pleural effusion), due to the heavy workload, it is very easy to cause the operator's fingers to be stiff, so that the work is forced to stop, and the suction can only be performed after the hand stiffness is relieved, which is time-consuming and laborious. In puncture cytology, it is sometimes necessary to rotate the syringe tube while aspirating after the needle is inserted, to find the best suction position, and sometimes it is necessary to rotate the syringe tube while inserting the needle (in puncture cytology, it is required to rotate the syringe once a week, then Needle 1-2 mm), at this time, it is necessary to keep the negative pressure in the cavity relatively stable, but also to maintain the amount of needle insertion per unit angle of rotation. This operation is difficult and difficult for beginners to master, often resulting in operation failure. Even for skilled operators, sometimes the aspirated tissue autodissolves in the lumen due to too long suction time, resulting in inaccurate test results. In addition, the inhalation volume of ordinary syringes is controlled by the strength of the operator's hands, and it is not easy to accurately control (such as the standard deviation of spinal cord aspiration is 0.05 ml).

In addition, the existing syringes are generally composed of a syringe body and a needle in separate parts. A liquid outlet tube is provided on the front surface of the syringe body, and the needle is socketed on the liquid outlet tube through a needle seat. However, the connection between the needle of such a syringe and the body of the syringe is not firm enough. In the process of taking medicine or injecting, due to reasons such as excessive internal pressure, sometimes the needle will fall off. At this time, the liquid medicine is wasted, which increases the difficulty of work. Ordinary syringes are likely to be used repeatedly. When users use repeated syringes, the liquid in the syringes will be contaminated and infected with bacteria. If the syringes are used by malicious people, it will threaten people's safety.

Chinese patent application: CN201453303U discloses a kind of screw self-locking syringe, it is characterized in that it is made up of syringe tube, piston, piston rod, pin etc. A small hole is formed on the upper edge of the syringe tube, a pin is inserted into the small hole, and the piston rod is inserted into the syringe tube; the piston is clamped on the front end of the piston rod, and threads are formed on the cylindrical surface of the middle part of the piston rod; when the pin is pulled out, , this syringe is used like a common syringe; when the outer end of the pin is pressed to insert the other end into the threaded groove on the surface of the piston rod, the piston rod is locked and cannot move axially, but at this time, rotating the piston rod can make the piston rod produce axial movement. Move in the direction to carry out the suction work, and the piston rod will lock itself when the rotation stops.

Chinese patent application: CN103495239A discloses a fall-off prevention syringe, including a tube body and a needle, a push cylinder is arranged in the tube body, and the needle is installed on a needle seat, and it is characterized in that: the needle seat is sleeved on the tube body The bottom end, and the needle seat is screwed with the tube body. In the present invention, the syringe body and the needle seat are threadedly connected, and the two are screwed tightly, so that even if the internal pressure is high, the needle will not fall off, and the drug absorption or injection is very safe. However, there is no report about the syringe that can prevent the needle from detaching from the syringe body, quantitatively measure the liquid medicine, and control the temperature of the liquid medicine.
