After the arterial blood sample is collected, the pressure of the arterial blood is high, the time for pressing the blood sample after blood drawing is longer, the time for preparing the venous blood sample is longer, and if the pressing time is short, local hematoma and other complications after blood drawing are easy to cause. Generally, a patient is pressed by using sterile gauze/cotton swabs for 5-10 minutes to stop bleeding, if the patient is receiving anticoagulant drug treatment or the blood coagulation time is long, the patient should be kept pressed on a puncture part for a longer time until the bleeding is stopped, and the force is limited to the condition that a certain amount of blood still passes when the finger artery jumps. However, ICU wards are often cared by no family and are mostly critical patients with unconsciousness, and under the conditions of more patients, less nurses and large workload in night shifts, the puncture points of the patients are always slowly oozed by blood without being found in time or subcutaneous hematoma is caused due to insufficient pressing time. In addition, in the common ward, due to the difference of lack of patience, insufficient pressing time, incorrect pressing mode, incorrect force and culture level of family members, the cotton swab is removed by pressing once to see whether bleeding exists, the bleeding is continuously pressed while the pressing is seen, and the continuous and proper pressing effect is not achieved. The present application therefore aims to provide a disposable tourniquet for collecting arterial blood samples which overcomes the above-mentioned drawbacks.

Detailed Description
The utility model will be further described with reference to the accompanying drawings, without limiting the scope of the utility model to the following:
as shown in fig. 1 and 2, the present application provides a disposable tourniquet for collecting an arterial blood sample, comprising a main body 1 and a band 2, the band 2 being connected to the main body 1. The main body 1 is used for pressing the puncture point to stop bleeding, and the bandage 2 is used for fixing the main body 1. The shape of the body 1 is defined by a hollow cylinder, and the body 1 has elasticity, and the body 1 can be elastically deformed when the body 1 is pressed. The main body 1 may be made of a material such as silicon gel to provide elasticity. Through the elastic deformation of hollow main part 1, can play the cushioning effect, and then can protect the puncture position effectively, avoid excessive extrusion to cause the puncture position painful.
Preferably, the band 2 has an upper band 2a and a lower band 2b, and the main body 1 is disposed between the upper band 2a and the lower band 2b in a state where the upper band 2a and the lower band 2b are stacked on each other, thereby achieving a better binding fixing effect to the main body. As shown in fig. 1, the lower surface of the lower strap 2b may be provided with adhesive such as a sticker so that it can be adhered to the skin of the patient. The upper surface of the lower strap 2b and the lower surface of the upper strap 2a may be detachably adhered to each other. For example, the upper surface of the lower band 2b is provided with a pile surface layer, and the lower surface of the upper band 2a is provided with a hook surface layer.
Preferably, the lower band 2b is provided with a sterile cotton pad 3. The puncture point can be covered and protected by the sterile cotton pad 3, and the infection of the puncture part can be avoided.
Preferably, the upper strap 2a is provided with a timing alarm. The timing alarm 4 can be used for timing the pressing time, and when the set pressing time is reached, the alarm can be given through sound, light and other modes to remind a user of reaching the specified pressing time, so that the hemostatic effect can be improved.
Preferably, the width of the aseptic cotton pad 3 is larger than the diameter of the main body 1. In use, the sterile cotton pad 3 may be tightly bound to the puncture site by the lower strap 2 b. When the upper band 2a is bound, the upper band 2a can properly press the main body 1, and at this time, the main body 1 is elastically deformed, so that the contact area of the main body 1 with the puncture site can be increased, and the pressing effect can be improved. The width of the aseptic cotton pad 3 is large, so that the main body 1 can be pressed and contacted with the peripheral part of the puncture point after being deformed. It will be appreciated that the surface of the sterile cotton pad 3 may be covered with a protective film to protect it from contamination when not in use.
Preferably, both end portions of the body 1 are open, wherein the body 1 can be internally filled with the pressing balls 5. When the blood oozing occurs at the puncture site due to insufficient compression force, the pressing ball 5 may be inserted into the body 1 and moved to the puncture site, thereby increasing the compression force of the puncture site. The position of the midpoint of the length of the body 1 may be used as a position for identifying the puncture point. That is, when pressing each time, all aim at the midpoint of the main body 1 with the puncture point, and then when the position of the pressing ball 5 needs to be adjusted, the pressing ball 5 only needs to be moved to the midpoint of the main body 1, so that the pressing ball 5 can be ensured to be in a state of pressing the puncture point.
