Description

Technical Field

[0001] This invention relates to the field of medical auxiliary equipment technology, and in particular to an automatic blood draw press device. Background Technology

[0002] There are a large number of discarded plastic products in our daily lives, such as plastic bottles, plastic boxes, and plastic crates. These plastic products are often used to hold chemicals, oils, and other products. The types of substances they hold are complex and they cause serious pollution to the environment. If these discarded plastic products are to be recycled, they must be effectively cleaned to remove impurities from the inner and outer surfaces, such as oil stains and dust. Generally, the recycling and cleaning of plastic products involves first breaking the plastic bottles into pieces before putting them into cleaning equipment for washing.

[0003] Publication number CN217797589U discloses a cleaning device, particularly an automatic pressure device for post-blood drawing. The technical problem is: to provide an automated cleaning device for plastic products that reduces manual operation and improves work efficiency. The technical implementation of this invention is: an automatic pressure device for post-blood drawing, including a base plate, support frames, a water storage frame, and connecting brackets. Three support frames are connected to the top of each base plate; two support frames on one side are connected to the top of a water storage frame; and connecting brackets are connected to both sides of the top of the support frames on the other side. The beneficial effect is: by rotating the winding wheel, the steel wire rope is tightened, thereby the steel wire rope drives the push block to move to the left, and the push block drives the plastic product to move to the left, whereby a brush cleans the plastic product.

[0004] Currently, the most common cleaning method for plastic products is agitation cleaning, which usually involves agitation motor driving an agitator shaft to rotate multiple agitator blades and agitate the plastic products located in the cleaning tank. However, the impurities generated during cleaning can easily accumulate inside the equipment, leading to a decrease in the cleaning efficiency. Therefore, this device provides an automatic pressure press after blood drawing. Summary of the Invention

[0016] The above-described at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0017] Firstly, when patients with coagulation disorders or hemophilia have undergone blood draws and need to apply pressure to the blood draw port, the patient can directly pick up the device and place the center point of the lower end of the adhesive block against the blood draw port. The patient then presses their thumb against the upper end of the adhesive mechanism, which initially applies pressure to the blood draw port. Next, the patient uses their other four fingers to support the lower end of the pressure-reducing mechanism and pushes upwards. During this process, the pressing mechanism ensures that the upper adhesive piece adheres tightly to the patient's skin under pressure, allowing the upper adhesive piece to... The adhesive block adheres tightly to the blood sampling port, and the port is pressed down using a clamping mechanism, confining it to the hand. By rotating the timer on the upper adhesive component, the timer can be set to the desired pressing time. Patients can set the pressing time according to their own condition and the suggestions of medical staff. When the pressing time is reached, a bell will ring to remind the patient, who can then check the specific situation after pressing. This device allows patients to conveniently press the blood sampling port with one hand after blood is drawn, reducing labor intensity.

[0018] Secondly, during the process of the patient observing the specific situation after pressing, the patient can first turn the flip knob away from the timer. Turning the flip knob drives the flip shaft to rotate, which in turn drives the flip frame to rotate within the flip slot. The rotation of the flip frame then drives the adhesive component to rotate, causing the adhesive block to disengage from the blood sampling port. At this point, the patient can observe the pressing situation at the blood sampling port through the flip slot. After observing and waiting for about half a minute, if the blood has already coagulated, no further pressing is needed, and the device can be removed. If the blood has not yet coagulated, or there is still bleeding, immediately reverse the direction. Rotating the flip-open knob returns the adhesive block to its original state, allowing for re-application and pressing of the blood drawing port. The designed adhesive mechanism, upper adhesive layer, and flip-open groove on the upper adhesive layer enable observation of the pressing process without removing the device. This avoids the need to remove the device after pressing for a specified time. If blood has not yet clotted or bleeding occurs, the device must be re-attached for further pressing, increasing the procedure time and complexity. Furthermore, the patient may bleed at any time during this process, requiring subsequent cleaning, which not only worsens the patient's condition but also affects the environment and increases patient discomfort.

[0019] Thirdly, if the blood has not coagulated after pressing for the specified time, or even if there is bleeding, immediately turn the knob in the opposite direction to return the adhesive block to its original state. Then, turn the timer again for about 5 minutes to perform a continuous pressing process. After the timer reaches the required time and rings to indicate that the time has elapsed, the adhesive component can be opened again to check the situation through the opening slot. Depending on the possible situations mentioned above, the opening and pressing can be repeated. This device is simple to operate, small in size, and will not cause discomfort during wear. Remove the device when the blood draw port is completely free of bleeding. Wearing this device will not affect the patient's normal rest and exercise, such as sleeping, eating, walking, and going to the toilet, as long as there is no strenuous exercise.

[0020] Fourth, after the lower and upper adhesive pieces are tightly attached to the patient's skin with the cooperation of the pressing mechanism, the arrangement of several first springs, several second springs, a buffer panel, and two snap-fit ​​plates ensures that the cushioning force borne by the lower adhesive piece is transmitted in three different directions, forming a tripod-like structure. Therefore, after the lower adhesive piece is tightly attached to the patient's skin, it can provide a very stable support and cushioning effect, avoiding bruising, ecchymosis, pain, and discomfort caused by prolonged tight wearing. Furthermore, since the upper and lower adhesive layers are made of cotton fibers and there are several ventilation holes on the lower adhesive plate, the patient is in a relatively comfortable state during the wearing process.

[0021] Fifth, since the lower and upper adhesive pieces are tightly attached to the patient's skin through the cooperation of the pressing mechanism, and the adjustment method and tightness accuracy of the adjustment component are determined by the spacing between several teeth evenly arranged on the side of the locking piece, according to the patient's different tolerance levels, after the upper adhesive piece and the upper adhesive piece are tightly attached to the patient's skin, the adhesive block can be moved away from or closer to the blood drawing hole by rotating the adhesive knob at a small angle. The linear movement of the component through the screw rotation allows for more precise movement distance. Thus, through the cooperation of the pressing mechanism and the adhesive mechanism, it can adapt to patients with different tolerance levels, improve the patient's wearing comfort, and is also widely applicable to different groups of people.

[0022] Sixth, the size of this device is roughly the same as that of a traditional watch, making it small, portable, and easy to operate. Therefore, patients with coagulation disorders and hemophilia can purchase one to carry with them. If they are injured and bleeding due to bumps or other incidents, they can immediately take out the device and wear it to activate the hemostatic pressure effect, greatly improving their safety. Because if the bleeding does not stop, and the wound is not continuously pressed in time, the patient is likely to lose consciousness due to excessive blood loss, posing a significant safety hazard if no one notices. This also avoids the need to constantly apply pressure during medical treatment, which is too tiring and can easily cause local bruising, ecchymosis, pain, and discomfort.

[0023] Seventh, this device can also be used for medicated treatment of the hands or legs. When a patient's hands or legs are injured, the appropriate upper patch can be selected according to the wound condition and the degree of medicated treatment. The upper patch and the locking part are then fixedly connected. The required medicated treatment drug is then pasted onto the lower end of the patch block on the upper patch. The fixing principle is the same as the hemostatic pressure principle. At the same time, the patch block in the patch assembly can be flipped open according to the patching mechanism, so that the patch block is left outside the flip-open groove, which makes it easy to replace the required medicated treatment drug. The wound condition can also be viewed through the flip-open groove.

[0024] When the weather is cold, patients with coagulation disorders and hemophilia may have more difficulty clotting their blood after a blood draw. In this case, a heating layer can be attached to the lower end of the patch to promote blood circulation, reduce the time required for blood clotting, and facilitate blood clotting. After the patient bleeds, a cold compress can also be attached to the lower end of the patch and can come into contact with the wound when the device is pressed to achieve a cold compress effect and provide hemostasis. The cold compress at the lower end of the patch can also be removed at any time depending on the patient's degree of coldness.

[0025] After medical staff have drawn blood from a regular patient's hand, the blood pressure application method is the same as that used for patients with coagulation disorders and hemophilia. The timer is set to the required pressing time, and an alarm will sound when the time is up. The device is then removed to complete the pressing operation. This device allows patients to easily press the blood drawing port with one hand after the blood draw is completed. Attached Figure Description

Detailed Implementation

[0045] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0046] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0047] Reference Figures 1-16 As shown, this embodiment of the invention provides an automatic pressure device after blood drawing, including a timer 1, a lower adhesive component 2, an upper adhesive component 3, a relief mechanism 4, a pressing mechanism 5, and an adhesive mechanism 6. The lower adhesive component 2 is disposed at the upper end of the relief mechanism 4. The lower adhesive component 2 and the upper adhesive component 3 can be driven to adhere to the skin through the cooperation of the pressing mechanism 5 under the action of force. The upper adhesive component 3 is connected to the relief mechanism 4 through the pressing mechanism 5. The timer 1 is disposed on the upper adhesive component 3. The adhesive mechanism 6 is disposed on the upper adhesive component 3. After the lower adhesive component 2 and the upper adhesive component 3 are attached to the skin, the relief mechanism 4 will have a relief and comfort effect.

[0048] After blood is drawn from a normal patient, applying pressure to the puncture site with a cotton swab for about 3 to 5 minutes is usually sufficient. However, patients with coagulation disorders or hemophilia have abnormalities in their blood vessel walls, platelets, coagulation factors, anticoagulation, and fibrinolysis, leading to either increased or decreased blood clotting ability. Therefore, these patients may experience persistent bleeding after blood is drawn. Their blood clotting recovery is weaker compared to normal patients, and bruising and ecchymosis are more likely to occur after prolonged pressure. In such cases, persistent bleeding is more likely, requiring 15 to 20 minutes of pressure on the puncture site. It takes about 10 minutes to achieve the effect of stopping the bleeding. Currently, patients often cannot accurately determine the duration of self-pressure, resulting in insufficient pressure to achieve the desired hemostasis. Furthermore, prolonged pressure can cause excessive arm pain and high labor intensity. In addition, if the patient is bleeding profusely from an injury and the wound is not continuously pressured in time, the patient can easily lose consciousness due to excessive blood loss, posing a significant safety hazard if no one is around to notice. Therefore, this device provides an automatic pressure device after blood drawing, which has the advantages of small size, easy portability and operation. It can be used not only for stopping bleeding after blood drawing but also for applying medication. It is clamped to the required site by means of pressure.

[0049] Preferably, the lower bonding component 2 includes a lower bonding layer 21 and a lower bonding plate 22. The lower bonding plate 22 is disposed on the damping mechanism 4 and is in a sliding fit with the upper and lower parts. The lower bonding layer 21 is disposed on the lower bonding plate 22. The lower bonding plate 22 is provided with a plurality of ventilation holes 221. The lower bonding plate 22 is provided with grooves 222 on both sides of its lower end.

[0050] The lower bonding plate 22 has several ventilation holes 221, which facilitates air circulation and reduces the possibility of bruising and ecchymosis.

[0051] Preferably, the deceleration mechanism 4 includes a deceleration housing 41, a deceleration panel 42, a first spring 43, a second spring 44, side plates 45, a rod 46, and a locking plate 47. The lower fitting plate 22 is inside the deceleration housing 41 and is vertically slidingly fitted. There are two side plates 45, which are symmetrically arranged on the upper ends of both sides of the deceleration housing 41. There are several first springs 43, which are arranged in pairs, forming two groups. The two groups of first springs 43 are symmetrically arranged, and the upper ends of the two groups of first springs 43 are respectively connected to the lower ends of the corresponding side plates 45. The deceleration panel 42 is located at the lower ends of the two groups of first springs 43. There are two locking plates 47, which are symmetrically arranged. The center points of 7 are all connected to the inner sidewall of the buffer housing 41 by shafts and are all rotatably connected. The upper ends of the two buffer panels 42 are provided with slots 421 on both sides. One end of the two snap-fit ​​plates 47 is located in the corresponding groove 222 and the other end is located in the corresponding slot 421. There are two second springs 44. The upper ends of the two second springs 44 are connected to the lower end of the lower fitting 2, and the lower ends of the two second springs 44 are connected to the upper end of the buffer panel 42. There are several rods 46. The several rods 46 are respectively slidably engaged with the lower end of the corresponding side plate 45. The upper ends of the buffer panels 42 are fixedly connected to the several rods 46 on both sides. The several rods 46 are arranged in two groups of two, and the two groups are symmetrically arranged.

[0052] After the upper adhesive piece 2 and the lower adhesive piece 3 are tightly attached to the patient's skin with the cooperation of the pressing mechanism 5, refer to... Figures 1 to 4 As shown, through the arrangement of several first springs 43, several second springs 44, a buffer panel 42, and two snap-fit ​​plates 47, the buffering force borne by the lower adhesive piece 2 is transmitted in three different directions, forming a tripod-like state. Therefore, after the lower adhesive piece 2 is tightly attached to the patient's skin, it can play a very stable support and buffering role, avoiding bruising, ecchymosis, pain and discomfort caused by prolonged tight wearing. Furthermore, due to the upper adhesive layer 31 and the lower adhesive layer 21 being made of cotton fibers and the several ventilation holes 221 provided on the lower adhesive plate 22, the patient is in a relatively comfortable state during the wearing process.

[0053] Preferably, the pressing mechanism 5 includes a locking assembly 51 and an adjusting assembly 52. ​​The locking assembly 51 is disposed at the upper end of one side of the deceleration housing 41, and the adjusting assembly 52 is disposed on the locking assembly 51. The locking assembly 51 includes a locking housing 511, a spring piece 512, a locking block 513, and a locking member 514. The locking housing 511 is disposed at the upper end of one side of the deceleration housing 41, and the locking block 513 is located inside the locking housing 511 and at an off-center position. The lower end of the locking block 513 is rotatably connected to the inner wall of the locking housing 511. The spring piece 512 is located inside the locking housing 511 and between the locking block 513 and the inner wall of the locking housing 511. The locking housing 511 is in a state of tight fit with the spring piece 512. The lower end of the locking member 514 extends into the locking housing 511. The side end of the locking member 514 is in a sliding fit with the inner wall of the locking housing 511. The upper end of the locking block 513 is provided with several teeth. The locking member 514 has a plurality of teeth evenly arranged on its side end. The teeth on the upper end of the locking block 513 are in a matching state with the teeth evenly arranged on the side end of the locking member 514. Initially, the teeth on the locking block 513 and the teeth evenly arranged on the side end of the locking member 514 are in an engaged state. The adjusting assembly 52 includes an adjusting shaft 521, an adjusting block 522, and an adjusting knob 523. The adjusting shaft... One end of 521 is rotatably connected to the inner wall of the locking housing 511, and the other end passes through the locking housing 511 and is located outside the locking housing 511. The other end is threadedly connected to the locking housing 511. The adjusting block 522 is sleeved on the adjusting shaft 521 and is located inside the locking housing 511. The lower end of the adjusting block 522 is in contact with the upper end of the locking block 513. The adjusting knob 523 is located at the other end of the adjusting shaft 521 and is located outside the locking housing 511.

[0054] Before using this device, the adjusting knob 523 can be rotated to drive the adjusting shaft 521 to rotate, thereby causing the adjusting block 522 to move closer to the spring piece 512. This results in the spring piece 512 being in a relatively compressed state while the adjusting block 522 is still in contact with the spring piece 512. At this time, several teeth on the locking block 513 are disengaged from several teeth evenly arranged on the side of the locking member 514. Then, the upper contacting member 3 is pulled upward, thereby causing the locking block 513 to move upward within the locking housing 511. When the lower end of the locking member 514 is higher than the lower end of the locking block 513, the adjusting knob 523 is rotated back to its original position, and the locking block 513 returns to its original position via the spring piece 512. Then, the upper contacting member 3 is pressed downward, so that the teeth at the lower end of the locking member 514 engage with the teeth at the upper end of the locking block 513. This state is the initial state of the device.

[0055] Preferably, the upper adhesive component 3 includes an upper adhesive layer 31, the side end of which is connected to the upper end of the locking component 514. The upper adhesive layer 31 is provided with a flip-open groove 311. The timer 1 is set on the upper adhesive layer 31 and located at the side end of the flip-open groove 311. The upper adhesive layer 31 and the lower adhesive layer 21 are made of cotton fibers. The inner side of the upper adhesive layer 31 and the lower adhesive layer 21 are both arc-shaped and the arc shape is adapted to the patient's hand and leg.

[0056] The upper adhesive layer 31 and the lower adhesive layer 21 are made of cotton fibers, which enables the device to have good breathability after pressing. The inner side of the upper adhesive layer 31 and the lower adhesive layer 21 are both arc-shaped, and the arc shape is adapted to the patient's hand and leg, making the device widely applicable to different groups of people.

[0057] The bonding mechanism 6 includes a flip-up component 61 and a bonding component 62. The flip-up component 61 is disposed in a flip-up groove 311 on the upper bonding layer 31, and the bonding component 62 is disposed on the flip-up component 61. The flip-up component 61 includes a flip-up shaft 611, a flip-up frame 612, and a flip-up knob 614. One end of the flip-up shaft 611 is disposed on the inner side wall of the flip-up groove 311 for rotatable connection, and the other end passes through the flip-up groove 311 and is located outside the upper bonding layer 31. The other end of the flip-up shaft 611 is connected to the flip-up groove. 311 is a threaded connection. The flip-up frame 612 and the flip-up groove 311 are adapted to each other. The flip-up frame 612 is located inside the flip-up groove 311 and its side end is sleeved on the flip-up shaft 611. The flip-up knob 614 is located at the other end of the flip-up shaft 611 and at the side end of the upper bonding layer 31. The upper end of the flip-up frame 612 is provided with a stop block 613. One end of the stop block 613 extends beyond the flip-up groove 311. The flip-up frame 612 is provided with a bonding groove 615. The bonding groove 615 is provided with an internal thread.

[0058] By extending one end of the stop block 613 beyond the flip-open slot 311, when the flip-open knob 614 rotates to drive the flip-open shaft 611, and then drives the bonding component 62 on the flip-open frame 612, if the stop block 613 happens to pass through the upper bonding member 3 to block it, the bonding block 621 in the bonding component 62 can contact the blood drawing hole in a horizontal manner, thereby improving the pressing quality of the device.

[0059] The bonding component 62 includes a bonding block 621 and a bonding knob 622. The outer side wall of the bonding block 621 is provided with an external thread that matches the internal thread of the bonding groove 615. The bonding block 621 and the bonding groove 615 are threadedly connected. The bonding knob 622 is located at the upper end of the bonding block 621.

[0060] When the bonding block 621 is pressed against the blood sampling port and the procedure is completed, bacterial infection may occur if the device is used for the next hemostasis operation. Therefore, after the device is used, the bonding block 621 can be rotated in the bonding groove 615 by rotating the bonding knob 622, and the bonding block 621 can be removed from the bonding groove 615. At this time, the bonding component 62 can be taken to the required position for cleaning and disinfection. After cleaning and disinfection, the bonding block 621 can be rotated into the bonding groove 615 by rotation. There is no need to clean and disinfect the entire device, which facilitates cleaning and disinfection and avoids the possibility of bacterial infection during the next hemostasis operation.

[0061] The upper fitting part 3 and the locking part 514 are slidably coupled left and right and are detachable. A fixing knob 515 is provided at the sliding engagement point of the upper fitting part 3 and the locking part 514. The upper fitting part 3 can be of various different shapes. The fixing knob 515 and the locking part 514 are threadedly connected.

[0062] Reference Figure 15 and Figure 16 As shown, when patients with coagulation disorders and hemophilia are injured while out or at home, the appropriate upper fitting 3 can be installed on the locking part 514 according to the shape of the wound. The wound can be pressed by this device, and then the patient can go to the hospital for treatment. This avoids the risk of the patient losing consciousness due to excessive blood loss if the wound is not continuously pressed in time due to unstoppable bleeding, which could cause a great safety hazard.

[0063] By rotating the fixing knob 515, the upper bonding member 3 that is in contact is released, so that the locking member 514 and the upper bonding member 3 are in a sliding state, thereby removing the upper bonding member 3 from one side of the locking member 514. After removal, the appropriate upper bonding member 3 can be replaced. Then, the locking member 514 and the upper bonding member 3 are fixed and limited by rotating the fixing knob 515 again.

[0064] After blood is drawn from patients with coagulation disorders or hemophilia, when pressure needs to be applied to the blood draw port, the patient can directly pick up the device and place the center point of the lower end of the adhesive block 621 against the blood draw port, pressing their thumb against the upper end of the adhesive mechanism 6. This provides initial pressure to the blood draw port. Next, the patient uses their other four fingers to support the lower end of the deceleration mechanism 4 and pushes upwards. During this process, the pressing mechanism 5 ensures that the upper adhesive piece 3 adheres tightly to the patient's skin under pressure, allowing the upper adhesive piece 3 to... The adhesive block 621 is tightly attached to the blood drawing port. The blood drawing port is pressed and confined to the hand by clamping it with a clip. Then, by rotating the timer 1 on the upper adhesive part 3, the timer 1 is set to the required pressing time. The patient can set the required pressing time according to their own condition and the suggestions of medical staff. When the pressing time is reached, the bell will ring to remind the patient. At this time, the patient can check the specific situation after pressing. Thus, after the blood is drawn, the patient can easily press the blood drawing port with one hand and reduce the labor intensity.

[0065] During the process of the patient checking the specific situation after pressing, the patient can first turn the flip knob 614 away from the timer 1. Turning the flip knob 614 drives the flip shaft 611 to rotate. The rotation of the flip shaft 611 causes the flip frame to rotate within the flip groove 311. The rotation of the flip frame 612 causes the adhesive component 62 to rotate, thereby causing the adhesive block 621 to disengage from the pressing position of the blood drawing port. (Refer to...) Figure 14 In the state shown, the patient can observe the pressure of the blood drawing port by flipping open the slot 311. After observing and waiting for about half a minute, if the blood has coagulated, there is no need to continue pressing and the device can be removed. If the blood has not coagulated or there is still bleeding, the flipping knob 614 should be turned in the opposite direction to drive the adhesive block 621 back to its original state and the blood drawing port should be re-adheded and pressed. Through the adhesive mechanism 6, the upper adhesive layer 31, and the flipping slot 311 on the upper adhesive layer 31, the pressure can be observed without removing the device. This avoids the need to remove the device directly after pressing for a specified time. If the blood has not coagulated or there is still bleeding, the device needs to be put back on for pressing, which increases the operation process and time. During this process, the patient may bleed at any time, and after bleeding, cleaning is required, which will not only aggravate the patient's condition but also affect the environment and increase the patient's troubles.

[0066] If the blood has not coagulated after pressing for the specified time, or if there is still bleeding, immediately reverse the rotation of the flip knob 614 to bring the adhesive block 621 back to its original state. Then, turn the timer 1 again to set a timer for about 5 minutes to perform a continuous pressing process. After the timer 1 reaches the required time and rings to indicate that the time has elapsed, the adhesive component 62 can be opened again and the situation can be checked through the flip slot 311. Depending on the possible situations mentioned above, the opening and pressing can be repeated. This device is simple to operate, small in size, and will not cause discomfort during wear. Remove the device when the blood draw port is completely free of bleeding. Wearing this device will not affect the patient's normal rest and exercise, such as sleeping, eating, walking, and going to the toilet, as long as there is no strenuous exercise.

[0067] Since the lower and upper adhesive pieces 3 are tightly attached to the patient's skin through the cooperation of the pressing mechanism 5, and the adjustment method and tightness accuracy of the adjusting component 52 are determined by the spacing between several teeth evenly arranged on the side of the locking piece 514, according to the different pressure levels of the patient, after the upper adhesive pieces 3 are tightly attached to the patient's skin, the adhesive knob 622 can be rotated at a small angle to drive the adhesive block 621 to move away from or towards the blood drawing hole in the adhesive groove 615. The linear movement of the component through the screw rotation can make the movement distance more accurate. Thus, through the cooperation of the pressing mechanism 5 and the adhesive mechanism 6, it can be adapted to patients with different pressure levels, improving the patient's wearing comfort. At the same time, it is also widely applicable to different groups of people.

[0068] This device is roughly the same size as a traditional watch, making it small, portable, and easy to operate. Therefore, patients with coagulation disorders and hemophilia can purchase one to carry with them. If they are injured and bleeding due to bumps or other incidents, they can immediately take out the device and wear it to activate the hemostatic and pressure-relieving effect, greatly improving their safety. Because if the bleeding does not stop, and the wound is not continuously pressed in time, the patient is likely to lose consciousness due to excessive blood loss, which poses a significant safety hazard if no one notices. This also avoids the need to constantly apply pressure during the medical process, which is too tiring and can easily cause local bruising, ecchymosis, pain, and discomfort.

[0069] This device can also be used for medicated dressing treatment on the hands or legs. When a patient's hand or leg is injured, an appropriate upper adhesive piece 3 can be selected according to the wound condition and the degree of medicated dressing application. The upper adhesive piece 3 is then fixedly connected to the locking piece 514. The required medicated dressing treatment medication is then applied to the lower end of the adhesive block 621 on the upper adhesive piece 3. The fixing principle is the same as the hemostatic pressure principle. At the same time, the adhesive block 621 in the adhesive assembly 62 can be flipped open according to the adhesive mechanism 6, so that the adhesive block 621 is left outside the flip-open groove 311, which facilitates the replacement of the required medicated dressing treatment medication. The wound condition can also be viewed through the flip-open groove 311.

[0070] When the weather is cold, patients with coagulation disorders and hemophilia may have more difficulty clotting their blood after blood is drawn. In this case, a heating layer can be attached to the lower end of the patch 621 to promote blood circulation, reduce the time required for blood clotting, and facilitate blood clotting. After the patient bleeds, a cold compress can also be attached to the lower end of the patch 621 and can come into contact with the wound when the device is pressed to achieve a cold compress effect and provide hemostasis. The cold compress at the lower end of the patch 621 can also be removed at any time depending on the patient's degree of coldness.

[0071] After medical staff have drawn blood from the hand of a regular patient, the blood pressure method described above for patients with coagulation disorders and hemophilia can be used. By rotating timer 1 to set the required pressure time, a bell will ring when the pressure time is reached. At this point, the device can be removed to complete the pressure operation. This device allows patients to conveniently press the blood drawing port with one hand after the blood is drawn.

[0072] The above description is merely an embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
