A standard wound incision device for primate fingertip skin

Abstract

The invention provides a cutting device for a standard wound of fingertip skin of a primate. The cutting device for the standard wound of the fingertip skin of the primate aims at forming the cutting device on the basis of a primate animal bleeding time measuring model (wound cutting on fingertip skin), the cutting device can effectively, fixedly and accurately cut off the fingertip skin to form into a fingertip standard wound with relative fixed thickness, force and accuracy, accordingly accurate and effective testing data can be obtained and meanwhile an uncertain result and uncomfortable visual feelings caused by an unarmed operating behavior by directly cutting the fingertip through the surgical knife. According to the cutting device for the standard wound of the fingertip skin of the primate, a hollow pipe-shaped object with a suitable size is sleeved on a finger to fix the finger and flatly unfold the finger, a protruding position inside the pipe is used to fix a fingernail position (the front edge of a white line of the fingernail is served as the criterion for the length of the finger) of the finger, a cutter pressure device with a spring is arranged right above the protruding, the thickness of the exposed finger portion is relatively consistent when the finger is abutted,, then the upper cutter with the spring is pressed to cut off the fingertip skin, and the device is taken out conveniently, and the bleeding time is recorded.

Description

technical field [0001] The invention belongs to the field of biomedical devices, in particular to a standard incision tool for primate fingertip skin. Background technique [0002] Bleeding time is a commonly used indicator in clinical practice and animal experiments. It is used to evaluate the coagulation function of the body, related diseases, and the effects of anticoagulant and antithrombotic drugs. Chinese utility model patent and patent application number 201410165171.X, patent name "bleeding time detector" Chinese invention patent application for blood collection needle for bleeding time, used in the determination of bleeding time in primates (such as humans, monkeys, etc.) In practice, a standard skin incision is generally made on the arm of the upper limb to measure the time from bleeding to coagulation. Experiments have proved that using the skin incision at the end of the fingertip is a simple and effective method of measurement. Usually, the operator can use one ...

[0002] Bleeding time is a commonly used indicator in clinical practice and animal experiments. It is used to evaluate the coagulation function of the body, related diseases, and the effects of anticoagulant and antithrombotic drugs. Chinese utility model patent and patent application number 201410165171.X, patent name "bleeding time detector" Chinese invention patent application for blood collection needle for bleeding time, used in the determination of bleeding time in primates (such as humans, monkeys, etc.) In practice, a standard skin incision is generally made on the arm of the upper limb to measure the time from bleeding to coagulation. Experiments have proved that using the skin incision at the end of the fingertip is a simple and effective method of measurement. Usually, the operator can use one hand to hold the animal's fingers against each other. Fixed on the cutting board, use the other hand to take the scalpel to make the incision. This method of freehand operation to form the incision has many disadvantages, such as: the skin slides during the incision process, the incision position is not easy to fix and repeat, and the cutting force is difficult Control, the size and thickness of the incision are not easy to control, and the distance between the nails and pulps of primates is inconsistent, resulting in large errors in the measurement results. The present inventors have invented a set of devices for incision of primate fingertip skin standard wounds, which can make up for the above deficiencies
