Description

Technical Field

[0001] The invention relates to the technical field of PICC cannula hemostasis, in particular to a hemostasis device. Background Art

[0002] From the outside, PICC is a thin, soft and flexible special catheter that is inserted into the peripheral vein of the patient's arm by a specialist nurse, and then the end is placed in the superior vena cava or subclavian vein, which are central veins.

[0003] The primary function of a PICC is to establish a safe and scientific infusion channel for cancer patients or those requiring long-term chemotherapy. As we all know, chemotherapy drugs and intravenous nutrition drugs are highly irritating and can easily cause phlebitis, leakage, and tissue necrosis. PICCs are designed to protect human blood vessels and soft tissues, sparing people from the pain of repeated punctures.

[0004] To investigate the role of cold compress in reducing puncture site bleeding and hematoma after peripherally inserted central venous catheterization (PICC) surgery. Methods: Two hundred patients undergoing PICC were randomly divided into a control group and a treatment group. The control group underwent routine surgical procedures, while the treatment group applied an ice pack (100ml, wrapped in a dry towel) in addition to the dressing at the puncture site. The incidence of puncture site bleeding and hematoma in both groups was observed 24 hours after surgery. Results: After 24 hours, the incidence of puncture site bleeding and hematoma in the treatment group was significantly less than that in the control group. Conclusion: Cold compress at the puncture site after PICC surgery can effectively reduce the incidence of puncture site bleeding and hematoma.

[0005] As the closest prior art, Chinese patent publication CN115363681A relates to the field of medical care technology and discloses a hemostatic device for cold compress after PICC catheterization, comprising a fixing assembly, a cold compress assembly being provided on the fixing assembly, a replacement assembly being provided on the same vertical plane as the cold compress assembly, a fixing belt being provided in the fixing assembly, a first rack being fixedly connected to one end of the fixing belt, and a second rack being fixedly connected to the other end of the fixing belt, and when the gear rotates, the gear will carry the first rack and the second rack on both sides to move toward each other.

[0006] However, due to structural limitations, current hemostatic devices can only be used for cold compress treatment to achieve the purpose of cold compress hemostasis. When the wound is large, it is not conducive to rapid hemostasis. At this time, pressure needs to be applied while cold compress is assisted to stop the bleeding. Summary of the Invention

[0009] The first hemostatic structure is used for cold compress hemostasis at a unilateral location;

[0010] The second hemostatic structure is used for cold compress hemostasis on the other side, and the first hemostatic structure and the second hemostatic structure are designed to be separated;

[0011] The first hemostatic structure includes a first pressurized hemostatic component, which is arranged at the inner center of the first hemostatic structure. The first pressurized hemostatic component includes an ice compress layer, an adhesive layer, a fabric outer layer, a limiting sleeve, a matching frame and a stamping airbag. The upper end of the stamping airbag is provided with a matching frame, and the upper end of the matching frame is fixed to the fabric outer layer through a limiting sleeve.

[0013] Specifically, the plug-in connecting frame is made of plastic material and is elastic. The third Velcro is clamped and fixed to the adapter end frame, which is convenient for quick combination and realizes the binding and fixation of the first hemostatic structure.

[0014] Specifically, the first pressurized hemostasis component also includes a first connecting tube, a first pressurizing valve, a second pressurizing valve and a second connecting tube. The ram airbag is provided with a first connecting tube, and the front end of the first connecting tube is connected to the first pressurizing valve. The ram airbag is provided with a second connecting tube at the end away from the first connecting tube, and the front end of the second connecting tube is connected to the second pressurizing valve. The arrangement of the first connecting tube, the first pressurizing valve, the second pressurizing valve and the second connecting tube facilitates the pressurized inflation of the ram airbag.

[0015] Specifically, the second hemostatic structure includes a fifth link, a sixth link, a fourth Velcro, a fifth Velcro and a second pressurized hemostatic component. The side ends of the second pressurized hemostatic component are fixedly connected with the fifth link and the sixth link. The fifth link and the sixth link are arranged in parallel, and the center of the fifth link and the sixth link is provided with a fourth Velcro. The sides of the fifth link and the sixth link are fixedly connected with the fifth Velcro. The combination of the fifth link, the sixth link, the fourth Velcro, the fifth Velcro and the second pressurized hemostatic component can cooperate with the first hemostatic structure, facilitate operation and use, and increase the usable area.

The first connecting conduit, the first pressurizing valve, the second pressurizing valve and the second connecting conduit can be used to fill the ram airbag with gas to expand the ram airbag. When the ram airbag expands, it can squeeze the ice compress layer, the adhesive layer and the outer layer of the fabric to make the ice compress layer fit the skin. While performing the cold compress, press-type hemostasis can be performed.

[0021] Second, the present invention provides a second hemostatic structure, and the second hemostatic structure can be combined with the first hemostatic structure to perform a large range of hemostatic treatment. The second pressurized hemostatic component inside the second hemostatic structure has the same structure as the first pressurized hemostatic component. The first hemostatic structure and the second hemostatic structure are connected by a fourth Velcro, and then the fifth and sixth connecting straps are wrapped around to achieve overall annular coverage. The fifth Velcro can be coordinated with the second and third Velcros at the inner end of the first hemostatic structure to achieve multi-stage connection, thereby improving the connection stability of the first and second hemostatic structures.
