The invention discloses an automatic hand expansion device for blood sampling. The automatic hand expansion device for blood sampling comprises an automatic telescopic device and a silicone bag covering the automatic telescopic device; the automatic telescopic device comprises a telescopic motor, and the top of a movable rod of the telescopic motor is connected with a U-shaped ejector rod; the telescopic motor is provided with a power wire and a power plug; the left end of the silicone bag is provided with a switch which can control the startup and the shutdown of the telescopic motor; the front end of the silicone bag is connected with four silicone sleeves for sleeving the other fingers, except the thrum, of a hand, the left end or the right end of the back end of the silicone bag is provided with a thumb silicone sleeve for sleeving the thumb. Through the coordination of the specially-made automatic telescopic device and the elastic bag, the automatic hand expansion device for blood sampling can drive the hand to automatically perform clenching and opening actions.
Description
technical field [0001] The invention relates to an auxiliary device for blood collection, in particular to an automatic hand expansion device for blood collection. Background technique [0002] When taking blood, the general nurse will ask the blood taker to hold an elastic object, such as an elastic ball, and then need to keep holding and releasing the elastic ball during the blood collection process, the purpose is to make the blood vessels Filling, to avoid vasoconstriction sticking to the cut surface of the needle, causing blockage; but many people will have a certain sense of tension when taking blood, which makes the hands very unnatural, resulting in clenching and relaxing movements that are not smooth, thus affecting blood collection. Contents of the invention [0003] The present invention aims at the above problems and proposes an automatic hand expansion device for blood collection. The expansion device can automatically contract and expand, thereby making the b...
