Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an infrared-assisted vein positioning blood collection needle. Background Art

[0002] A venous blood collection needle is a medical device used to collect venous blood samples from the human body. It usually consists of a needle and a pipe connected to a blood collection tube. An existing venous blood collection needle (publication number: CN214073308U) has at least the following defects during use:

[0003] 1. When using the above-mentioned venous blood collection needle, medical staff need to find a vein suitable for blood collection by observation, touch, etc., which requires certain skills and experience. If the medical staff fails to find a suitable vein position, it may lead to blood collection failure or require multiple needle insertions, thereby reducing the success rate of blood collection. Therefore, a venous blood collection needle with infrared scanning is urgently needed;

[0004] 2. Since the above-mentioned venous blood collection needle cannot be installed with an infrared scanning device during use, and the existing blood collection needles are mostly disposable, if the infrared scanning device is directly installed on the disposable venous blood collection needle, the infrared device will also be discarded when it is discarded, which is costly. Therefore, a venous blood collection needle with a detachable fixing clip is urgently needed;

[0005] 3. Since the above-mentioned venous blood collection needle cannot directly observe the exact position of the blood vessel, it can only rely on feel and experience to judge the position of the blood vessel, which is not as accurate as directly observing the image. It is easy to cause medical staff to insert the needle inaccurately or require multiple attempts. Therefore, there is an urgent need for an infrared-assisted venous blood collection needle with a display. Utility Model Content

[0006] The main purpose of the utility model is to provide an infrared-assisted vein positioning blood collection needle, which can effectively solve the problems in the background technology.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0010] A fixing clip, the fixing clip is mounted on the clamping plate, an infrared scanning device is mounted on the fixing clip, and a data line is mounted on the infrared scanning device;

[0011] A display, the data cable is connected to the display, and the display is equipped with control buttons;

[0012] A conduit is provided with a sealing head.

[0013] Preferably, the display contains a built-in power supply.

[0014] Preferably, the interior of the clamping plate is a hollow pipe.

[0015] Preferably, one end of the conduit is connected to a clamping plate.

[0016] Preferably, the infrared scanning device comprises an infrared light source, a receiver and an image processing unit, and the processing unit calculates the position and depth of the blood vessel according to the infrared signal received by the receiver and generates a corresponding image.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] 1. The utility model installs an infrared scanning device to scan the vein position and depth in real time, so that medical staff can more easily find a suitable position for blood collection, which helps to reduce multiple needle insertions and failures and improve the success rate of blood collection;

[0019] 2. By installing the fixing clip, the disposable blood collection device can be quickly replaced, reducing the risk of disease transmission caused by the reuse of the blood collection device and improving the work efficiency of medical staff;

[0020] 3. By installing a display and transmitting the information scanned by the infrared scanning device to the display, medical staff can intuitively observe the condition of the blood vessels and improve the accuracy of acupuncture. BRIEF DESCRIPTION OF THE DRAWINGS
