Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a midline catheter puncture site compression hemostasis device. Background Art

[0002] PI CC catheterization, also known as peripherally inserted central catheter, is now very common in clinical chemotherapy patients. It is a safe and effective catheterization technique. The principle of midline catheter is roughly the same as that of PI CC.

[0003] Clinically, it is common for local bleeding and exudation to occur at the puncture site of PI CC or midline catheter. In the prior art, hospitals usually cut gauze and roll it into a roll, and fix it on the puncture site with medical tape to compress the puncture site to stop bleeding.

[0004] A Chinese patent publication (publication number: CN219982967U) discloses a PI CC, midline catheter puncture site rapid compression hemostasis device, which includes a hemostatic roll and a fixing patch. A compression chamber is provided in the middle of the hemostatic roll, and the compression chamber extends along the length direction of the hemostatic roll, so that the hemostatic roll can be compressed to an elliptical cross-section. The middle of the bottom surface of the fixing patch is connected to the upper surface of the hemostatic roll. The fixing patch includes a first patch and a second patch, and the first patch and the second patch are integrally formed. The fixing patch can be converted between a first state and a second state. When the fixing patch is in the first state, the second patch is folded and attached to the surface of the first patch, and the first patch surrounds the surface of the hemostatic roll. When the fixing patch is in the second state, the first patch and the second patch are both in the same horizontal state to fix the hemostatic roll at the puncture site. In general, the utility model has a simple structure, is easy to use and has strong practicality. However, in actual use, the hemostatic roll is fixed by directly sticking it on the patient's skin through a fixing patch. This method uses an adhesive with poor air permeability, which brings discomfort to the patient. In addition, when replacing the hemostatic roll, it needs to be replaced as a whole, and the hemostatic roll cannot be replaced individually according to usage requirements. In addition, the fixing pressure between the hemostatic roll and the patient needs to be adjusted regularly to avoid excessive compression and discomfort. The utility model cannot regularly adjust the tightness of the hemostatic roll fixed by the bandage, and needs to be manually adjusted regularly, which is time-consuming and labor-intensive, reduces practicality, and is not conducive to hemostasis. For this reason, a midline catheter puncture port compression hemostasis device is proposed. Utility Model Content

[0005] In view of this, the utility model provides a midline catheter puncture site compression hemostasis device to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0009] Further preferably, the inner wall of the hemostatic roll is provided with a sponge tube; through the provision of the sponge tube, the sponge tube is inserted into the gap in the middle of the hemostatic roll to support the hemostatic roll. When the hemostatic roll is manually squeezed, the elastic force of the sponge tube improves the effect of squeezing the hemostatic roll to stop bleeding.

[0010] Further preferably, a release paper is bonded to the top of the bonding sheet; through the provision of the release paper, an adhesive is coated between the bonding sheet and the release paper, and the release paper covers the bonding sheet to prevent the bonding sheet from being contaminated.

[0011] Further preferably, both sides of the release paper are fixedly connected with extension sheets; the provision of the extension sheets facilitates tearing the release paper off the adhesive sheet.

[0012] Further preferably, one end of the fixing rope is fixedly connected to a plastic rope head; through the provision of the plastic rope head, one end of the fixing rope is wrapped, making it convenient for one end of the fixing rope to pass through the rope buckle.

[0013] Further preferably, a rope buckle is installed on the outside of the fixing rope; through the setting of the rope buckle, after the fixing rope passes through between the fixing cloth belt and the elastic bandage, the fixing rope is pulled to adjust the position of the fixing rope according to the compression requirement, one end of the fixing rope is inserted into the rope buckle, the rope buckle is moved to a position close to the fixing cloth belt, and the rope buckle is fixed on the fixing rope. The volume of the rope buckle is larger than the space between the fixing cloth belt and the elastic bandage, which prevents the fixing rope from moving and limits the position of the fixing rope, thereby fixing the position of the elastic bandage after being wrapped.

[0014] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0015] 1. During the use of the utility model, the hemostatic roll is wound and fixed by an elastic bandage, and then the elastic bandage is fixed by a fixing rope and a rope buckle, without the need for bonding with an adhesive, and has high air permeability, making the patient more comfortable, and the hemostatic roll is fixed on the elastic bandage by an adhesive sheet, and when the hemostatic roll needs to be replaced separately, it can be torn off from the elastic bandage and replaced with a new one, which improves practicality and is conducive to hemostasis.
