Description

Technical Field

[0001] The invention relates to the field of syringe sampling, in particular to a novel mechanical transmission syringe sampling device. Background Art

[0002] As we all know, before performing medical injections or sending samples for scientific experiments, there will be a syringe sampling stage. Generally, when sampling with a syringe, one hand holds the syringe steady, and the other hand pulls the piston at the end of the syringe, using the pressure difference between the inside of the syringe and the surface of the reagent to press the reagent into the syringe. This method is easy to operate, purely manual, and does not require auxiliary equipment. However, the pressure difference between the inside and outside of the syringe required for sampling must all be provided by manual pulling. When it comes to large quartz glass syringes with good airtightness, it often requires manual labor to provide a large pulling force, which often leads to backaches, hand pain, and labor. At the same time, since it is not easy to maintain stability when holding manually, problems such as back suction and bubbles are very likely to occur during the sampling process, which in turn leads to ineffective effort and time-consuming exhaust in the later stage.

[0003] The existing technical solution (utility model patent number CN98220286.5) provides a timed, automatic syringe for intravenous injection. The device uses a series of sophisticated mechanical transmissions to achieve the automatic forward movement of the syringe needle plug end cover when the power is on to complete the automatic injection process. At the same time, there is a reset handle in the device to complete the needle plug reset after the injection is completed. In the event of a power outage, the injection work can also be completed by manually operating the handle. However, it is of little help to the syringe sampling stage. Although the reset handle can provide a device reset process, it is not known whether this process can be combined with the syringe sampling stage.

[0004] The utility model patent number (CN202120548694.8) provides a syringe that facilitates large-dose liquid bolus injection. Through the action of the pulley and the injection pulley, the pulley can reduce the force of extracting and injecting the imaging agent (a common reagent in the field of nuclear medicine examination), thereby reducing the intensity of manual operation, saving effort and time. However, the device itself is a specific syringe and cannot help with common syringe sampling work.

[0005] Therefore, in order to solve the problems existing in the prior art, the present invention provides a method of transmitting the rotational force of the rotating end turntable to the tension of the syringe end by mechanical transmission, and adopting the transmission form of a pulley group to realize a labor-saving and time-saving injection method. The present invention can also be adapted to a variety of common syringes to achieve higher practicality. Summary of the invention
