Description

Technical Field

[0001] This utility model relates to the field of hemostatic patch technology, and in particular to a pressure hemostatic patch for use after intravenous blood collection. Background Technology

[0002] Venous blood collection is a very common procedure in clinical diagnosis and treatment. It is widely used in many medical fields such as routine blood tests, biochemical index analysis, infectious disease screening, and gene testing. It is a key step in obtaining patients' blood samples for disease diagnosis, disease monitoring, and health assessment.

[0003] During venous blood collection, the lancet penetrates the skin and blood vessel wall, causing local damage to the vessel and allowing blood to seep into the surrounding tissue. Normally, the body's own clotting mechanism activates, forming a thrombus through a series of complex physiological reactions, such as platelet aggregation and clotting factor activation, to seal the ruptured blood vessel and stop the bleeding. However, this physiological hemostasis process takes time, and blood may continue to seep out in the initial period after blood collection, especially when the vascular pressure at the collection site is high, the patient has abnormal clotting function (such as hemophilia or taking anticoagulants), or the blood collection procedure is improper (such as the needle bevel not being completely withdrawn from the vessel or insufficient pressure time). Currently, hemostasis is mainly achieved by applying pressure to the collection site using hemostatic bandages or adhesive bandages, but this method has many inconveniences. For example, hemostatic bandages or adhesive bandages do not have a pressure function, requiring continuous manual pressure for a period of time. This not only increases the workload of medical staff, but also makes it difficult to accurately control the pressure and duration, easily leading to poor hemostasis or patient discomfort. In addition, for patients with abnormal coagulation function, the hemostatic effect of manual pressure is more limited, and may require longer pressure or other hemostatic measures. Utility Model Content

[0004] This utility model aims to at least solve the technical problem that existing hemostatic bandages or wound dressings lack pressure function, and innovatively proposes a pressure hemostatic patch for use after intravenous blood collection.

[0005] To achieve the above-mentioned objectives of this utility model, this utility model provides a pressure hemostatic patch for use after venous blood collection. The hemostatic patch includes an adhesive part and a hemostatic part, the hemostatic part being disposed on the adhesive part; the hemostatic part includes:

[0006] A hemostatic cotton layer is disposed on the adhesive portion;

[0007] A compression plate is movably mounted on the hemostatic cotton layer;

[0008] A pressure chamber is disposed on the extrusion plate and is used to apply downward pressure to the extrusion plate;

[0009] A limiting plate is disposed at the top of the pressure chamber;

[0010] The control cavity is located on the limiting plate.

[0011] As an optional embodiment of this utility model, the pressure chamber is optionally connected to the air bladder via a connecting pipe, and a switch valve is provided on the connecting pipe.

[0012] As an optional embodiment of this utility model, the pressure chamber may be an air collection bladder.

[0013] As an optional embodiment of this utility model, the connecting pipe may be detachably mounted on the pressure chamber.

[0014] As an optional embodiment of this utility model, the hemostatic patch may further include a timer and a control button. The control button is located on the top of the control cavity and is used to control the state of the timer. The timer is located inside the control cavity.

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] like Figure 1 As shown, a pressure bandage for use after venous blood collection includes an adhesive portion 1 and a hemostatic portion 2, the hemostatic portion 2 being disposed on the adhesive portion 1; the hemostatic portion 2 includes:

[0029] Hemostatic cotton layer 201 is disposed on the adhesive part 1; as Figure 1 and 2 As shown, the hemostatic cotton layer 201 has a rectangular structure, with its two sides fixed to the adhesive part 1 and close to the bottom of the adhesive part 1.

[0030] A compression plate 202 is movably mounted on the hemostatic cotton layer 201. The compression plate 202 has a rectangular structure and is made of a lightweight and elastic material, such as medical-grade plastic or rubber, to ensure sufficient pressure is applied to the hemostatic cotton layer 201 when pressure is applied. Specifically, the compression plate 202 is placed on top of the hemostatic cotton layer 201, and when the compression plate 202 is under pressure, it can directly transmit the pressure to the hemostatic cotton layer 201.

[0031] Pressure chamber 203, disposed on the extrusion plate 202, is used to apply downward pressure to the extrusion plate 202; for example Figure 1 and 2As shown, in this embodiment, the pressure chamber 203 is an air collection bladder, which is similar to a balloon. Specifically, the air collection bladder is inflated by connecting pipe 4 and air filling bladder 3, so that the pressure chamber 203 expands and applies pressure to the extrusion plate 202.

[0032] A limiting plate 204 is disposed on the top of the pressure chamber 203. The limiting plate 204 has a rectangular structure, with both ends fixed to the adhesive part 1 and the bottom close to the top of the pressure chamber 203. It is used to prevent the pressure chamber 203 from applying pressure to the extrusion plate 202. The limiting plate 204 can provide a downward resisting force to the pressure chamber 203, ensuring that the pressure chamber 203 stably applies pressure to the extrusion plate 202.

[0033] A control cavity 205 is disposed on the limiting plate 204. The control cavity 205 stores power, a timer, and an alarm. The control cavity 205 is made of rigid plastic to ensure its structural strength. A control button 6 is located on the top of the control cavity 205, allowing medical personnel to start, stop, and adjust the timer duration. Both ends of the control cavity 205 are fixed to the adhesive portion 1, and its bottom is located on the top of the limiting plate 204.

[0034] In use, first set the hemostasis time using the control button, then fix the hemostasis part 2 to the patient's blood collection site using the adhesive parts 1 at both ends. Next, inflate the pressure chamber 203 using the air bladder 3 through the connecting pipe 4. As the pressure chamber 203 expands, the compression plate 202 applies downward pressure to the hemostatic cotton layer 201, which then provides stable pressure to the patient's blood collection site, achieving hemostasis. When the set hemostasis time is up, the alarm emits an audible and visual alarm signal to remind medical staff or the patient to remove the hemostatic patch promptly.

[0035] The hemostatic patch of this embodiment effectively improves hemostasis, reduces the workload of medical staff, and enhances patient comfort.

[0036] As an optional embodiment of this utility model, the pressure chamber 203 is optionally connected to the air bladder 3 via a connecting pipe 4, and a switch valve 5 is provided on the connecting pipe 4.

[0037] like Figure 1 As shown, the pressure chamber 203 is provided with an installation joint, which is connected to one end of the connecting pipe 4. The other end of the connecting pipe 4 is connected to the air bladder 3. A switch valve 5 is also connected to the connecting pipe 4.

[0038] When in use, open the switch valve 5 on the connecting pipe 4, and press the air bladder 3 to inflate the pressure chamber 203. As the air is continuously inflated, the pressure chamber 203 gradually expands, applying downward pressure to the compression plate 202. The compression plate 202 then transmits the pressure to the hemostatic cotton layer 201, which in turn applies stable pressure to the patient's blood collection site, achieving hemostasis. To stop inflation, simply close the switch valve 5. This design allows medical personnel to easily control the pressure of the hemostatic patch to meet the hemostatic needs of different patients.

[0039] As an optional embodiment of this utility model, the pressure chamber 203 may be an air collection bladder.

[0040] like Figure 2 As shown, the air-collecting bladder allows the pressure chamber 203 to expand evenly during inflation, thereby ensuring that the pressure applied by the compression plate 202 to the hemostatic cotton layer 201 is uniform and stable. Furthermore, the air-collecting bladder has good elasticity and resilience, allowing it to quickly return to its original shape after gas release, facilitating reuse.

[0041] As an optional embodiment of this utility model, the connecting pipe 4 may be detachably mounted on the pressure chamber 203.

[0042] like Figure 1 As shown, in this embodiment, the connecting tube 4 is detachably mounted on the pressure chamber 203. This facilitates the reuse of the connecting tube 4 and the air-filled balloon 3, and also makes it easier to clean and disinfect them, ensuring the hygiene and safety of the hemostatic patch. Furthermore, the detachable design makes the hemostatic patch more flexible, allowing for the replacement of different air-filled balloons 3 or connecting tubes 4 as needed to meet the hemostasis requirements of different patients.

[0043] As an optional embodiment of this utility model, the hemostatic patch may also include a timer and a control button 6. The control button 6 is disposed on the top of the control cavity 205 and is used to control the state of the timer. The timer is disposed inside the control cavity 205.

[0044] like Figure 1 and 2 As shown, during use, control button 6 activates the timer, and the hemostasis time is set; the timer then begins timing. When the set hemostasis time is reached, the timer automatically triggers the alarm, emitting an audible and visual alarm signal to remind medical staff or the patient to remove the bandage promptly. This design not only ensures the accuracy of the hemostasis time but also significantly reduces the workload of medical staff and improves hemostasis efficiency. In this embodiment, the alarm is installed inside the control cavity 205.

[0045] As an optional embodiment of this utility model, the control button 6 may also be used to adjust the timing duration of the timer.

[0046] As an optional embodiment of this utility model, the width of the adhesive part 1 is optionally smaller than the width of the hemostatic part 2.

[0047] like Figure 1 As shown, the width of the hemostatic part 2 is designed to be greater than the width of the adhesive part 1. This design allows the hemostatic part 2 to better cover the patient's blood collection site, providing a larger pressure area and thus improving the hemostatic effect. At the same time, the smaller width of the adhesive part 1 reduces the adhesion area of ​​the hemostatic patch to the patient's skin, reducing patient discomfort.

[0048] As an optional embodiment of this utility model, the bottom of the adhesive part 1 may be provided with a fixing layer 101.

[0049] like Figure 2 As shown, in this embodiment, the fixing layer 101 is specifically a layer of medical-grade adhesive material. This adhesive material has excellent adhesion and skin affinity, enabling it to firmly adhere the hemostatic patch to the patient's skin while avoiding skin irritation or allergies. The fixing layer 101 ensures that the hemostatic patch is not easily detached during use, thereby guaranteeing the stability and durability of the hemostatic effect.

[0050] As an optional embodiment of this utility model, the extrusion plate 202 may be an arc-shaped plate with its arc surface facing the hemostatic cotton layer 201.

[0051] like Figure 1 and 3 As shown, the compression plate 202 is designed as an arc-shaped plate with the arc surface facing the hemostatic cotton layer 201, so that the compression plate 202 can fit more precisely with the blood collection site when pressure is applied, thereby improving the effect of pressure hemostasis.

[0052] As an optional embodiment of this utility model, the material of the hemostatic cotton layer 201 may be medical-grade sterile cotton.

[0053] like Figure 1 As shown, the hemostatic cotton layer 201 in this embodiment is made of medical-grade sterile cotton, which has good moisture absorption and breathability, keeping the blood collection site dry and clean, which is conducive to wound healing. At the same time, the medical-grade sterile cotton can also effectively isolate external bacteria, reducing the risk of infection. The hemostatic cotton layer 201 not only improves the hemostatic effect but also enhances the comfort and safety of the bandage.

[0054] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
