Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a sterile drape for transradial artery access. Background Art

[0002] Transradial artery access refers to a method of establishing an intravascular access by puncturing and catheterizing the radial artery as the target blood vessel. The radial artery is an artery on the wrist, and the diameter of the radial artery at the wrist is small. Applying pressure directly to the puncture site is easy to stop bleeding. For most patients, transradial artery access has higher safety, allowing patients to get out of bed and walk immediately after the operation without being bedridden and immobilized, which can maximize the patient's self-care ability and liberate the legs. Moreover, transradial artery access can significantly improve the patient's comfort, reduce bed-related complications and nursing workload, and can also shorten the hospital stay and reduce the hospitalization cost. Therefore, transradial artery access is widely used in the field of coronary intervention diagnosis and treatment.

[0003] Before transradial artery access, skin disinfection is usually carried out, and then the parts not involved in the operation are covered with a sterile drape, leaving the parts that need to be exposed during the operation, that is, leaving the surgical field, and making the area around the surgical field a large sterile area. However, traditional sterile drapes still have many limitations in the use process. For example, the draping process is cumbersome, which will take a lot of surgical time and thus affect the progress of the operation; there is a possibility of being contaminated, and once contaminated, it is very likely to increase the risk of nosocomial infection, thus increasing the medical cost. Especially the cumbersome draping process further increases the possibility of the drape being contaminated. Summary of the Utility Model

[0025] See Figures 1 to 3 , this utility model provides a sterile drape for transradial artery access, including a drape main body 1. A drape hole 2 is provided on the drape main body 1. The front of the drape main body 1 is used to contact the patient's arm. A hand protection structure 3, an annular fixing structure 4, and a connection structure 5 are provided on the front of the drape main body 1; the hand protection structure 3 includes a hand protection cover 301 and a hand protection cavity 302. The hand protection cover 301 is provided on the left side of the drape main body 1. The hand protection cover 301 and the drape main body 1 jointly form the hand protection cavity 302. The left side of the hand protection cavity 302 is the closed side, and the right side is the open side. Specifically, one side of the hand protection cover 301 and the drape main body 1 jointly form the closed side of the hand protection cavity 302, and the other side of the hand protection cover 301 and the drape main body 1 jointly form the open side of the hand protection cavity 302; the annular fixing structure 4 includes an annular adhesive layer 401 and an annular anti-adhesive layer 402. The annular adhesive layer 401 is provided at the edge of the drape hole 2, and the inner edge of the annular adhesive layer 401 is flush with the edge of the drape hole 2.

[0026] The basic working principle of the sterile drape for transradial artery access involved in the present utility model is as follows: By providing a hand protection structure 3, the hand protection cover 301 can be sleeved on the patient's hand. The patient's hand enters the hand protection cavity 302 through the opening side of the hand protection cavity 302, and the closed side of the hand protection cavity 302 provides more comprehensive protection for the patient. The integrated setting of the hand protection structure 3 and the drape main body 1 can also ensure the integrity of the drape main body 1 and is convenient for manufacturing; By providing an annular fixing structure 4 at the edge of the drape hole 2, the drape main body 1 can be directly fixed at the surgical field site; By providing an annular adhesive layer 401 and an annular anti-adhesive layer 402, when draping is required, only the annular anti-adhesive layer 402 needs to be torn off, and the annular adhesive layer 401 is adhered to the patient's arm to expose the puncture site of the transradial artery access. The drape main body 1 wraps around the patient's arm, and then the upper and lower edges of the drape main body 1 are fixedly connected by using the connecting structure 5, so as to stabilize the sterile drape on the arm and isolate other body surfaces of the patient, greatly simplifying the draping operation and ensuring the aseptic requirements of the surgical field.
