AI Technical Summary

Problems solved by technology

However, due to many human factors, the puncture and needle insertion are often inaccurate, which affects the accuracy of treatment.
Sometimes it is necessary to repeat the needle for many times, and in severe cases, it will lead to mispuncture, which will bring great pain and risk to the patient
Therefore, the existing medical technology still has the problem that it is difficult to accurately locate the puncture point, which will have a great impact on the nearby skin tissue
At the same time, there are problems such as incomplete and incomplete extraction of congestion, low curative effect, and large side effects.

Embodiment 1

[0029] Please refer to figure 1 , the present embodiment provides a device for pulling out blood congestion, including a tank body 1, an air negative pressure mechanism, and a puncture needle 2 detachably arranged in the tank body 1, wherein the puncture needle 2 includes a needle tube body 21. A needle body 22 arranged at the front end of the needle body 21, and a mounting part 23 arranged at the rear end of the needle body 21, a ventilation hole 211 is opened on the side of the front end of the needle body 21, and is installed in the needle body 21. There is a negative pressure chamber integrally formed in the part 23, the front end of the negative pressure chamber communicates with the air hole 211, and the rear end is connected to the air negative pressure mechanism. In this embodiment, both the air negative pressure mechanism and the tank body 1, and the air negative pressure mechanism and the puncture needle 2 are detachably connected, which facilitates quick disassembly...

Embodiment 2

[0051] The main difference between this embodiment and Embodiment 1 is:

[0052] Described step (1) comprises the following steps:

[0053] First, take pictures on the patient's back with a human body infrared imager to obtain the temperature distribution of each area on the patient's back, and the area with low temperature is the area of ​​blood stasis on the patient's back;

[0054] Then, through the thermal tomography analyzer, the relationship between the heat distribution on the patient's back surface and the depth of the heat source is found, and the information on the depth of the internal heat source, heat radiation value, shape and change of the heat source is obtained, and the blood stasis area on the patient's back is obtained. Through these two steps, the blood stasis area can be accurately found, that is, the area to be punctured.

Abstract

The invention discloses an extravasated blood extraction device which comprises a tank, an air negative-pressure mechanism and a puncture needle, and wherein the puncture needle is detachably arrangedin the tank. The puncture needle comprises a needle pipe, a needle and a mounting portion, the needle is arranged at the front end of the needle pipe, the mounting portion is arranged at the rear endof the needle pipe, a vent hole is formed in the side of the front end of the needle pipe, a negative-pressure cavity is integrally formed in the needle pipe and the mounting portion, the front end of the negative-pressure cavity is communicated with the vent hole, and the rear end of the negative-pressure cavity is connected to the air negative-pressure mechanism. The invention further disclosesan extravasated blood extraction method base don the extravasated blood extraction device. The extravasated blood extraction device is reasonable in structure design, convenient to operate, safe, reliable and practical, puncture points and puncture depth are accurate, extravasated blood is completely extracted, a whole process is safe and reliable, effects are rapid, and side effects are avoided.

Description

technical field [0001] The invention relates to the medical field, in particular to a device for pulling out blood congestion and a method for pulling out blood congestion. Background technique [0002] Congestion in the human body, that is, thrombus, can cause blockage of meridians, which can easily lead to hemiplegia, varicose meridians, etc. In mild cases, it can also cause back pain. There are many traditional methods for treating congestion (thrombosis), some of which use massage, some of which use cupping, some of which use compresses, roasting, and scalding. In recent years, some of them use magnetic therapy, electrotherapy, etc. However, the curative effect is not ideal, and it cannot be cured, but only relieved. [0003] Therefore, with the development of medicine, puncture techniques have appeared for various diseases caused by congestion. When a lesion occurs inside the human body, it is sometimes necessary to use a puncture to biopsy or treat the lesion. Usual...
