CN-122005211-A - Medical hemostatic patch

Abstract

The invention relates to the technical field of medical blood sampling and hemostasis, and discloses a medical hemostatic patch which comprises a hemostatic part and a marking part, wherein marking liquid is packaged in the marking part, and at least one tearable packaging piece is packaged in the marking liquid. The hemostatic patch is provided with the marking part, the marking of the blood sampling point of the patient is realized while hemostasis is carried out, and if the patient needs to carry out other nursing operation which can influence the internal or external pressure of the blood vessel of the patient within a certain time after blood sampling, no matter whether the subsequent operation is a replacement, the marking of the previous blood sampling point can be seen when the subsequent operation is carried out, thereby avoiding the blood sampling puncture point of the previous time from bleeding caused by the subsequent nursing operation and avoiding unnecessary pain and risk brought to the patient.

Description

Medical hemostatic patch Technical Field The invention relates to the technical field of medical blood sampling and hemostasis, in particular to a medical hemostatic patch. Background In hospital clinics and outpatients, a large number of patients need to puncture and collect blood for testing every day in order to achieve the purpose of assisting diagnosis. For needle drawing hemostasis, early medical staff presses a lancing point by fingers by using a cotton ball immersed with disinfection alcohol, and later presses by using a cotton swab with a small short stick, and the risk of secondary hemorrhage and even infection due to insufficient pressing time exists due to the fact that the fingers can be far away from the lancing point by using the cotton swab. In order to solve the problem, patent document CN216222005U discloses a blood sampling hemostatic plaster, which comprises a hemostatic layer, an adhesive layer and an elastic compression layer, wherein the elastic compression layer is sealed inside a vacuum bag, a sealing head is arranged at the opening of the vacuum bag, the vacuum bag is positioned between the hemostatic layer and the adhesive layer, and a structure that the elastic compression layer expands and extrudes the hemostatic layer along with the extraction of the sealing head is formed. However, in some clinical patients, other nursing operations such as blood pressure measurement, CT (computed tomography) examination enhancement and the like, which can affect the internal or external pressure of the blood vessel formation of the patient, can be performed within a certain time (for example, within 24 hours) after the blood sampling, and if the operation is performed carelessly, the external compression operation or the puncturing operation is performed on the same limb (hand or foot) with insufficient blood sampling interval time, the previous bleeding (subcutaneous bleeding and swelling as shown in fig. 18) and the drug extravasation (skin injury as shown in fig. 19) can be caused by the increase of the internal pressure of the blood vessel due to the insufficient recovery of the previous blood sampling point. Typical patients such as patients with arteriovenous fistula, breast cancer postoperative, superior vena cava compression syndrome and the like are usually prohibited from carrying out nursing operations such as transfusion, blood pressure measurement, blood drawing and the like on one limb of the patients, and some patients even on two upper limbs (namely two hands) are prohibited from carrying out nursing operations such as transfusion, blood pressure measurement, blood drawing and the like, so that the number of limbs of the patients which can carry out nursing operations such as transfusion, blood pressure measurement, blood drawing and the like is reduced, and the conditions that blood sampling (arteriovenous blood sampling) and blood pressure measurement, transfusion and the like are easy to occur only on the limb on the same side of the patient. In addition, computed Tomography (CT) is widely used worldwide as a common radiological examination means. CT enhancement scanning requires the use of iodine-containing contrast agents to enhance the sharpness of the image, thereby improving the accuracy of the diagnosis. However, the use of iodine contrast agents is not without risk, contrast agent extravasation or leakage is a known complication that occurs when contrast agent leaks from within the blood vessel into the surrounding tissue. Although the clinical consequences of most contrast agent extravasation events are mild, severe extravasation can lead to localized tissue damage and even severe complications such as the inter-fascia syndrome. Before CT enhancement scanning, intravenous needle puncture (special high-pressure-resistant 20G indwelling needle) is needed, and the contrast agent needs to be rapidly injected into blood vessels at high pressure in the injection process. If blood is pumped up and down the puncture blood vessel, the contrast agent can be extravasated, and the limbs of the patient are seriously swollen and severely painful. At present, the mode of avoiding the occurrence of the situation completely depends on the cautiousness of medical staff to realize avoiding, but the needle eye of a puncture needle (blood taking needle and indwelling needle) used clinically is too small, and the puncture part is not easy to be found. The medical staff can memorize the previous blood sampling time and the blood sampling position of the same patient and inquire the previous blood sampling time and the blood sampling position of the patient. However, the memory of the person is limited, the medical staff often has shift or occasionally negligence, the state of the patient can not be remembered, and the risk that the same side limb or the same blood vessel with insufficient blood sampling interval time is selected in clinical treatment operation is difficult to avoid.
