Description

Technical Field

[0001] The present invention relates to the technical field of medical care, and particularly to a hemostatic device for cold compress after intravenous blood collection. Background Art

[0002] In the medical field, intravenous blood collection is a common examination method used to obtain blood samples from patients, and then analyze various components in the blood, providing important bases for the diagnosis, treatment, and prevention of diseases. However, after intravenous blood collection, due to damage to blood vessels, blood is likely to ooze out from the puncture site, resulting in local bleeding, and even may cause adverse reactions such as ecchymosis and swelling, which not only bring physical discomfort and pain to patients, but also may affect subsequent treatment and nursing work.

[0003] Currently, the commonly used hemostatic method in clinical practice is to compress the puncture site with a cotton ball or a gauze pad. Although this method is simple to operate, it has some obvious deficiencies. The hemostatic effect of the cotton ball or gauze pad depends on the pressing force and time of the patient. If the pressing force is insufficient or the pressing time is too short, it may lead to incomplete hemostasis and continuous blood oozing; while if the pressing force is too large or the pressing time is too long, it may cause compressive injury to the local tissue of the patient, resulting in new discomfort. In addition, the cotton ball or gauze pad is prone to displacement during the pressing process, especially when the patient moves, and may not always maintain effective compression on the puncture site, affecting the hemostatic effect.

[0004] In recent years, a few special hemostatic devices for after intravenous blood collection have emerged on the market, but most of these devices have complex structures, are inconvenient to use, and have high costs, making it difficult to be widely promoted and applied in medical institutions at all levels. Some hemostatic devices have a certain cold compress function, but the cold compress effect is not good, and they cannot effectively reduce the local tissue temperature, thus failing to achieve the ideal hemostatic and swelling-reducing purposes.

[0005] In summary, the existing hemostatic means after intravenous blood collection have problems such as unstable hemostatic effect, inconvenient operation, and poor comfort. There is an urgent need for a new hemostatic device that can effectively solve the above problems to improve the hemostatic effect after intravenous blood collection, reduce the pain of patients, and promote the smooth progress of medical care work.

[0016] Preferably, a number of puncture protrusions are intermittently arranged on the lower side wall of the stabbing block. The diameter of the puncture protrusion is set to 5 mm, which is convenient for puncturing the upper side wall of the cold compress bag and the lower side wall of the heat - assisting bag to open water holes.

[0017] Preferably, the upper side wall of the cold compress bag and the lower side wall of the melting aid bag are coplanar, facilitating the interconnection of the cold compress bag and the melting aid bag after puncture.

[0018] (III) Beneficial Effects

[0019] The present invention provides a hemostatic device for cold compress after intravenous blood collection, with the following beneficial effects:

[0020] 1. Based on the principle of heat absorption during the melting of ice cubes in the cold compress bag, this device performs cold compress on the puncture site to stop bleeding. Meanwhile, the melting aid in the melting aid bag accelerates the melting of the ice cubes, enhancing the cold compress effect. The folding mark design on the outer side wall of the cold compress bag enables it to be bent and shaped according to the shape of the puncture site, fitting closely to the patient's skin to ensure uniform and comfortable cold compress.

Detailed implementation mode

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0031] As Figure 1-6 shown, the embodiment of the present invention provides a hemostatic device for cold compress after intravenous blood collection, including a cold compress bag 1. Ice cubes are contained in the cold compress bag 1. A melting aid bag 3 is fixedly connected to the upper side wall thereof. Two limit sleeves 301 are fixedly connected to the upper side wall of the melting aid bag 3 and close to both sides. The melting aid bag 3 is movably connected with a fixing strap 2 through the two limit sleeves 301, which is convenient for the installation or disassembly of the fixing strap 2 and facilitates the reuse of the fixing strap 2. A heat conduction block 103 is fixedly connected to the middle of the bottom of the cold compress bag 1. The cooled heat conduction block 103 is in direct contact with the bleeding part of the patient, so as to perform cold compress hemostasis on the bleeding part of the patient.

[0032] A threaded cylinder 202 is fixedly connected to the middle of the fixing strap 2. The fixing strap 2 is threadedly connected with an adjusting screw 203 through the threaded cylinder 202. The lower end of the adjusting screw 203 is rotatably connected with a top block 206. Rotating the adjusting screw 203 can drive the top block 206 to move up and down. When the top block 206 moves downward, it will push the pricking block 302 downward. A pricking block 302 is fixedly connected to the middle of the upper side wall of the melting aid bag 3. A melting aid agent 303 is arranged inside the melting aid bag 3. The melting aid agent 303 can effectively accelerate the melting of ice cubes and absorb heat, thereby improving the cold compress effect of the cold compress bag.

[0033] A plurality of folding marks 101 are evenly arranged on the outer side wall of the cold compress bag 1, which is convenient for bending, so that the cold compress bag 1 is convenient for wrapping around the bleeding part. An opening is arranged on the left side wall of the cold compress bag 1, and a sealing strip 102 is fixedly connected inside the opening. The sealing strip 102 can seal the cold compress bag 1 to prevent the melted water from discharging.

[0034] On the outer side wall of the left end of the fixed strap 2, a hook-and-loop fastener rough surface 201 is fixedly connected. On the inner side wall of the right end of the fixed strap 2, a hook-and-loop fastener hook surface 205 is fixedly connected. The hook-and-loop fastener rough surface 201 cooperates with the hook-and-loop fastener hook surface 205 to facilitate the fixation of the hemostatic device to the patient's body.

[0035] The upper end of the adjusting screw 203 is fixedly connected with a turntable 204. The top block 206 is arranged opposite to the puncturing block 302. By rotating the turntable 204, the adjusting screw 203 can be driven to rotate, thereby driving the top block 206 to move up and down.

[0036] A melting aid 303 is arranged inside the melting aid bag 3. The melting aid 303 is one or two of brine, alcohol solution and ethylene glycol, which can greatly accelerate the melting speed of the ice cubes.

[0037] Both the melting aid bag 3 and the cold compress bag 1 are made of high-pressure polyethylene material, which can effectively improve the compressive effect of the melting aid bag 3 and the cold compress bag 1.

[0038] A plurality of puncturing protrusions 3021 are intermittently arranged on the lower side wall of the puncturing block 302. The diameter of the puncturing protrusions 3021 is set to 5 mm, which is convenient for puncturing the upper side wall of the cold compress bag 1 and the lower side wall of the melting aid bag 3 to open water holes.

[0039] The upper side wall of the cold compress bag 1 and the lower side wall of the melting aid bag 3 are arranged in the same plane, which is convenient for the cold compress bag 1 and the melting aid bag 3 to communicate with each other after puncturing.

[0040] Working principle

[0041] When using the hemostatic device for cold compress after intravenous blood collection, first pre-freeze the ice cubes in the cold compress bag 1 to make it reach a low temperature state. Then, bypass the fixed strap 2 around the part of the patient that needs cold compress and hemostasis, and fix the hemostatic device on the patient through the cooperation of the hook-and-loop fastener rough surface 201 and the hook-and-loop fastener hook surface 205 to ensure that the cold compress bag 1 is closely attached to the puncture site.

[0042] If it is necessary to enhance the cold compress effect, the turntable 204 can be rotated to drive the adjusting screw 203 to rotate, and then the top block 206 can be moved downward to push the puncturing block 302 to move downward, piercing the interlayer between the cold compress bag 1 and the melting aid bag 3, so that the melting aid 303 contacts the ice cubes. The melting aid 303 can accelerate the melting of the ice cubes. During the melting process, the ice cubes absorb a large amount of heat, and the cold is transmitted to the bleeding site of the patient through the heat conduction block 103 to achieve the effect of cold compress hemostasis.

[0043] The folding mark 101 on the outer wall of the cold compress bag 1 is designed to endow the cold compress bag 1 with good flexibility and plasticity, enabling it to bend and shape according to the shape of the puncture site, better conforming to the patient's skin, and improving the uniformity and comfort of cold compress. The sealing strip 102 effectively prevents the water after the ice melts from draining out of the cold compress bag 1, avoiding the wetting and contamination of the patient's skin by the water stain, keeping the puncture site dry and clean, and being conducive to the healing of the wound.

[0044] The cold compress bag 1 and the melting aid bag 3 are made of high-pressure polyethylene material, which has good compressive performance and flexibility, can withstand the pressure generated during the melting of the ice, and ensures the safety and reliability of the device. The design of the puncture protrusion 3021 on the lower side wall of the puncture block 302 facilitates quickly piercing the interlayer of the cold compress bag 1 and the melting aid bag 3 when needed, enabling the melting aid 303 to fully contact the ice, with simple operation and remarkable effect.

[0045] Embodiment 2

[0046] The difference between this embodiment and Embodiment 1 is that: there is no sealing strip 102 at the opening of the cold compress bag 1. Instead, after adding ice into the cold compress bag 1, it is sealed by a sealing machine. This design simplifies the structure of the cold compress bag 1 to a certain extent, but during use, it is necessary to pay attention to preventing the water after the ice melts from leaking from the opening, and it may be necessary to be more careful and firm during sealing to ensure safety during the cold compress process.

[0047] Embodiment 3

[0048] This embodiment is basically the same as Embodiment 1, with the difference lying in the material and structure of the cold compress bag 1. The cold compress bag 1 is made of a gel material, which has good flexibility and water absorption, can closely conform to the skin, and provide a more uniform cold compress effect. The gel material can maintain a certain shape and hardness after freezing, and at the same time has a certain elasticity, and will not cause excessive pressure on the patient's skin.

[0049] In the internal structure of the cold compress bag 1, multiple layers of intervals are set, and each layer of interval contains ice and the melting aid 303. This multi-layer design can increase the ice storage capacity, extend the cold compress time, and ensure continuous cold compress effect for a relatively long time after venous blood collection. When in use, through the cooperation of the adjusting screw 203 and the top block 206, the puncture block 302 can pierce through multiple layers of intervals simultaneously, enabling the melting aid 303 to contact the ice in each layer and accelerating the melting of the ice.

[0050] In addition, besides the folding marks 101, the outer sidewall of the cold compress bag 1 is also provided with massage bumps. These massage bumps can slightly massage the patient's skin during the cold compress process, promote local blood circulation, and relieve the discomfort that the patient may feel due to long-term cold compress. On the fixing strap 2, besides the hook surface 201 and the loop surface 205 of the Velcro, an elastic stretchable band is added. The design of the elastic stretchable band makes the fixing strap 2 fit the patient's body more closely when fixing, adapt to the shapes and sizes of different parts, and improve the stability and comfort of the fixation.

[0051] Embodiment 4

[0052] Compared with Embodiment 1, the main improvement in this embodiment lies in the design of the fixing strap 2 and the melting aid bag 3. The fixing strap 2 is made of an elastic material, having good elasticity and stretchability, and can more flexibly adapt to the body parts of different patients. Whether it is the arm, leg or neck, etc., it can closely fit and provide uniform pressure to ensure that the cold compress bag 1 is stably fixed at the puncture site. On the inner side of the fixing strap 2, a layer of soft padding is also provided. The padding is made of a material with good air permeability, such as cotton or sponge, which can reduce the friction and pressure of the fixing strap 2 on the patient's skin and improve the wearing comfort, especially suitable for long-term use.

[0053] The melting aid bag 3 is optimized in this embodiment. The melting aid 303 inside it is stored in a separated manner, and the brine, alcohol solution and ethylene glycol are respectively placed in different small sachets. When it is necessary to adjust the cold compress intensity, by rotating the adjusting screw 203, the top block 206 pushes the puncturing block 302 to puncture a specific small sachet, so as to precisely control the type and dosage of the melting aid 303. This separated storage design can not only flexibly select the melting aid 303 according to actual needs, avoid unnecessary waste, but also prevent the reaction between different melting aids 303 before use, ensuring the stability and reliability of the device.

[0054] At the same time, a temperature sensor and an indicator light are added to the outer sidewall of the melting aid bag 3. The temperature sensor can real-time monitor the temperature change inside the melting aid bag 3 and transmit the signal to the indicator light. The indicator light displays the current cold compress state in different colors and blinking frequencies according to the received temperature signal. For example, when the temperature is low, it shows blue and blinks steadily, and when the temperature gradually rises, it turns yellow and blinks rapidly, reminding medical staff or patients to adjust the cold compress device in time or take corresponding measures, further improving the intelligent level and use convenience of the device.

[0055] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
