Description

Technical Field

[0001] The invention relates to the technical field of hemostatic patch preparation, and in particular to a device and method for preparing a hemostatic patch for blood drawing. Background Art

[0002] At present, after medical staff draw blood for patients with low platelets, in order to avoid or reduce the occurrence of hematoma in patients, they usually apply a hemostatic patch with an airbag to the patient's puncture site. The surface of the airbag is provided with a drug-containing absorption pad. By inflating the airbag, the drug-containing absorption pad on the airbag effectively presses the patient's puncture site; at the same time, in order to achieve the ice compress effect of the hemostatic patch, the patient usually takes an ice cube and puts it in a sealed bag, then holds the sealed bag with ice cubes against the hemostatic patch, and then applies ice compresses around the puncture site. The whole process requires the patient to hold the sealed bag with ice cubes, which causes great inconvenience to the patient.

[0003] In order to avoid or reduce the inconvenience caused by handheld ice compresses to patients, some medical staff pierce holes in the hemostatic patch, and then connect the sealed bag containing ice cubes to the pierced hole of the hemostatic patch through a strapping tape or a rope, so as to combine the sealed bag containing ice cubes with the hemostatic patch.

The second moving mechanism 501 is installed in the shell 200, and the support seat 502 is installed on the second moving mechanism 501. The second moving mechanism 501 drives the support seat 502 to move closer to or away from the transverse driving mechanism 400. Two punching seats 503 are installed on both sides of the support seat 502 along the moving direction of the second moving mechanism 501, and the top surface of each punching seat 503 is provided with two punching holes 507 arranged at intervals; the two sides of the bottom of the second bracket 506 are respectively connected to the two punching seats 503, the punching cylinder 504 is connected to the second bracket 506 and is located directly above the support seat 502, the telescopic end of the punching cylinder 504 is connected to the bearing seat 505, and four punches 508 are provided at the bottom of the bearing seat 505, two of which are located at one end of the bearing seat 505, and correspond one-to-one to the two punching holes 507 of one punching seat 503; the other two punches are located at the other end of the bearing seat, and correspond one-to-one to the two punching holes of the other punching seat.

[0076] When the transverse driving mechanism 400 drives the hemostatic patch 100 for blood drawing clamped by the clamping mechanism 300 to move to the corresponding position with the punching and inflation mechanism 500, it is in the punching and inflation station; the second moving mechanism 501 drives the supporting seat 502 to move to the bottom of the U-shaped hollow 301, at this time, the two stamping seats 503 are located in the U-shaped hollow 301 of the clamping mechanism 300, and the ends of the first elastic base band 105 and the second elastic base band 106 close to the pressure plate are respectively located on the two stamping seats 503, and the first elastic base band 105 and the second elastic base band 106 are respectively located above the corresponding punching holes 507, and the pressure stop plate 101 and the air bag 116 of the hemostatic patch 100 for blood drawing are located between the two stamping seats 503. Then, the punching cylinder 504 is driven to push the bearing seat 505 and the punch 508 downward, and the punch 508 cooperates with the corresponding punching holes 507 to complete the punching of the two first connecting holes 107 on the first elastic base band 105 and the two second connecting holes 108 on the second elastic base band 106 .

[0077] Specifically, each punching seat 503 has a sliding cavity 509 with an open lower end surface at the bottom surface corresponding to the punching hole 507, and the sliding cavity 509 is connected to the corresponding punching hole 507, and the connection between the sliding cavity 509 and the corresponding punching hole 507 is a shrinking or bell mouth transition.
