Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a pressure hemostatic bandage. Background Technology

[0002] In hospitals, after blood is drawn from arteries or veins, patients need to apply pressure to the bleeding point with a cotton swab. If the bleeding is not stopped promptly, the pressure is applied improperly, or the time is too short, subcutaneous bruising can easily occur, causing blood to accumulate in the subcutaneous tissue and form a hematoma. Hematomas not only cause pain but may also affect subsequent observation and treatment.

[0003] However, many elderly and critically ill patients in clinical practice have limited mobility and accuracy, making it impossible for them to apply pressure to stop bleeding independently after fluid resuscitation or blood draws. Some patients with poor coagulation function require prolonged pressure to prevent excessive bleeding or subcutaneous hematoma formation. All of these situations require close monitoring and care from medical staff. However, due to limited human resources, medical staff cannot provide prolonged pressure to stop bleeding for every patient, which can lead to complications such as subcutaneous bruising or hematoma in some patients.

The side wall of the push rod 32 is provided with an elastic buckle 34, which has a V-shaped structure. The inner end face of both sides of the support base 31 is provided with a limiting block 35. The limiting block 35 cooperates with the elastic buckle 34. The length of the elastic arms extending from both sides of the V-shaped elastic buckle 34 is greater than the distance between the limiting blocks 35. When the push rod 32 is pressed down, the elastic arms on both sides of the elastic buckle 34 are pressed inward, so that the elastic buckle 34 passes between the limiting blocks 35. Below the limiting block 35, the two elastic arms of the V-shaped elastic buckle 34 spring outward, return to their original shape, and are locked below the limiting block 35, restricting the upward movement of the push rod 32. Through the cooperation of the elastic buckle 34 and the limiting block 35, the push rod 32 is fixed, ensuring the stability of the pressurization. When using, first align the hemostatic cotton 2 with the bleeding point, then tightly attach the bandage to the patient's limb. Next, install the pressure device 3 in the center of the positioning plate 5, and after fixing it, press the push rod 32 to apply pressure to the hemostatic cotton 2. After a certain period of time, tear off the bandage.

[0039] In this embodiment, please refer to Figure 3 The inner end faces of the two side walls of the support base 31 are provided with several limiting blocks 35. The number of limiting blocks 35 can be adjusted to increase the pressure. If the pressure is not enough, the push rod 32 can be pressed down to make the elastic buckle 34 on the push rod 32 cooperate with the limiting block 35 below to increase the pressure and meet the needs of different patients.

[0040] In this embodiment, please refer to Figure 4 The push rod 32 is threadedly connected to the support base 31. The height of the push rod 32 can be precisely adjusted by rotating the thread, thereby controlling the pressure. A knob 6 is fixedly installed on the top of the push rod 32 for easy rotation and up-and-down movement. A pad 36 is installed on the pressure plate 33. The bottom of the pad 36 is fixedly connected to the pressure plate 33 by a spring 37.
