Medical blood drawing auxiliary device

Abstract

The invention discloses a medical blood drawing auxiliary device, which comprises a shell, a control mechanism and a valve gate mechanism. The valve gate mechanism comprises an electromagnet, a spring, a fixed plate and a movable plate, the electromagnet is installed at the upper end of one side of the fixed plate, a guide pipe is installed at the side end of the electromagnet, the spring is sleeved with the guide pipe, a supporting base is installed in the middle of the fixed plate, and the upper end of the supporting base and the lower end of the movable plate are hinged together; the lowerend of the other side of the movable plate and the upper end of the other side of the fixed plate are respectively provided with an upper clamping block and a lower clamping block; the shell is provided with a vertically distributed fixing groove; the control mechanism comprises a detection circuit, a prompt circuit, a storage battery, a power socket, a power switch and a force sensitive resistorwhich are electrically connected with the electromagnet and installed in the shell. and the force sensitive resistor is arranged at the lower end in the fixing groove of the shell. The medical blood drawing auxiliary device is convenient to operate, can automatically close the collection process and remind the medical staff when the amount of blood collection reaches the required amount, thus bringing convenience to the medical staff and reducing the labor intensity of the medical staff.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a medical blood drawing auxiliary device. Background technique [0002] In clinical medicine, collecting a patient's blood sample and conducting physical and chemical analysis is a major technical means to obtain data related to the patient's condition. At present, the blood of patients is usually collected by medical staff using blood sample test tubes (including test tubes, needles, flexible tubes, etc.) through manual methods, first inserting the needle into the patient's vein, and then after fixing the needle, the medical staff opens the valve of the test tube. (that is, loosen the clamp of the hose clamping the test tube, etc.; or the medical staff directly bend the hose connected to the needle and the test tube to make it airtight before collecting, and straighten the hose after fixing the needle), so that the patient's intravenous The blood will flow b...

Problems solved by technology

The above-mentioned operation mode has the following disadvantages; first: when the medical staff is not concentrated and the blood sample in the test tube is enough, the hose is not closed in time, which will lead to too many blood samples collected, which will bring unnecessary impact to the patient's health; Its two: because the speed of blood reflux is faster, so the operation skill requirement to medical personnel is higher, general personnel can't operate effectively; Third: because shutting off blood to enter test tube needs manual operation, will bring inconvenience to medical personnel, increase It reduces the labor intensity of medical staff, and it is impossible to guarantee that the amount of blood samples collected will reach an accurate amount.
