Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of radial artery hemostasis devices, in particular to a radial artery hemostasis device and a production equipment thereof. BACKGROUND

[0002] In radial artery coronary intervention, cardiac radiofrequency ablation and other cardiovascular intervention surgeries, as well as radial artery bypass, arterial repair and other vascular surgeries, radial artery bleeding may occur, and hemostasis needs to be performed through compression, special hemostasis device or surgical suture.

[0003] The radial artery hemostasis device is a medical device for controlling radial artery bleeding, and its core function is to block the radial artery blood flow through physical compression to achieve rapid hemostasis and prevent complications, and to achieve dynamic balance regulation based on pressure blocking.

[0004] A Chinese patent document with the same applicant and the publication number CN221903849U discloses a visible compression hemostatic bandage, which comprises a patch and a transparent body fixed in the middle of the patch, the bottom side of the transparent body is provided with an absorption pad, the bottom side of the transparent body is provided with a limiting groove, the width of the limiting groove is consistent with the diameter of the intervention tube, the arrangement direction of the limiting groove is consistent with the insertion direction of the intervention tube, and one end of the limiting groove is in an open shape.

[0005] In the related technology in the above, in the process of using the above compression hemostasis device for radial artery hemostasis, it is found that since the transparent body is a non-regular non-rotating body structure, the top of the transparent body is for observation, and the bottom of the transparent body is for hemostasis, the transparent body is divided into an observation part at the top and a hemostasis part at the bottom of the transparent body, and the size of the observation part and the hemostasis part directly affects the actual hemostasis effect of the hemostasis device, the size of the observation part directly affects the observation effect of the hemostasis effect on the intervention site, and the size of the hemostasis part directly affects the hemostasis effect on the radial artery puncture site.

[0006] If the taper of the bottom of the transparent body is sharper, the compression hemostasis effect on the radial artery intervention cannula site is better, but as the taper increases, the patient's comfort is reduced, and as the taper decreases, the patient's comfort is improved but the hemostasis effect is reduced, and similarly, if the taper of the observation part increases, the magnification of the wound site is more obvious, but the bulge of the observation part affects the patient's daily life (such as changing clothes and resting the arm on the table), and the flatter the taper of the observation part is, the smaller the magnification of the wound site is, and the observation effect is less obvious, so the size design of the transparent body is particularly important. SUMMARY

[0007] In order to solve the taper problem of the hemostasis device while considering the hemostasis effect, observation effect, patient comfort and observation effect of medical staff, the present application provides a radial artery hemostasis device and a production equipment thereof.

[0008] The radial artery hemostat and the production equipment thereof provided by the application adopt the following technical scheme: The radial artery hemostat and the production equipment thereof comprise a patch and a fixing plate fixed on the patch, a fixing hole is formed in the middle part of the fixing plate, a transparent body is fixedly embedded at the middle part of the fixing plate, the transparent body is a non-rotating body structure arranged symmetrically, the transparent body is divided into an observation part and a hemostatic part by the fixing plate, the observation part is located on the side of the fixing plate away from the skin, the hemostatic part is located on the side of the fixing plate close to the skin, the haze of the transparent body is less than 5%, a penetration groove is formed on the bottom side of the transparent body, the penetration groove is perpendicular to the length direction of the patch, and one side of the penetration groove is in an open state; When the transparent body is cut in half along the length direction of the patch, the length of the observation part / hemostatic part is 16-20 mm, and the height of the observation part is 5-7 mm; that is, the cross section of the observation part along the length direction of the patch is a half-ellipse with a long side of 8-10 mm and a short side of 7.5-9.5 mm, and the cross section of the hemostatic part along the length direction of the patch is a half-ellipse with a long side of 8-10 mm, a short side of 7.5-9.5 mm and a height of 5.5-8.5 mm; When the transparent body is cut in half along the width direction of the patch, the length of the observation part / hemostatic part is 32-40 mm; that is, the cross section of the observation part along the width direction of the patch is a half-ellipse with a long side of 16-20 mm and a short side of 5-7 mm, and the cross section of the hemostatic part along the width direction of the patch is a half-ellipse with a long side of 16-20 mm and a short side of 7.5-9.5 mm; The size of the fixing plate along the length direction of the patch is twice the size of the transparent body along the length direction of the patch, the size of the fixing plate along the width direction of the patch is 1.5 times the size of the transparent body along the width direction of the patch, a separation piece is further arranged on the patch to facilitate the removal of the hemostat, and a suction member is further arranged on the bottom side of the transparent body to absorb blood and body fluid at the wound.

[0009] By adopting the above technical scheme, the radii of the hemostatic part and the observation part of the transparent body are controlled. When the application is cut along the length direction, the length corresponding to the arc surface of the hemostatic part is related to the distance between the ulna and the radius at the wrist of the human body. Since the intervention site is usually located at the radial artery out of the wrist during the intervention surgery, the distance between the ulna and the radius of the human body is 8-12 mm. Therefore, the length of the arc surface of the hemostatic part is controlled to be 16-20 mm, which can not only realize stable hemostasis when the transparent body is inserted between the ulna and the radius, but also reduce the distance between the application and the skin of the wrist caused by the excessive size of the transparent body, thereby reducing the problem of wound infection caused by foreign matter or bacteria entering through the gap between the application and the skin. At the same time, by controlling the height of the short side of the hemostatic part to be 7.5-9.5 mm, the radius of the contact part of the hemostatic part and the skin can be matched with the radius after pressing, which can not only realize stable hemostasis of the radial artery, but also reduce the compression of other blood vessels caused by excessive taper, improve the comfort of the patient, and reduce the discomfort of the patient's wrist caused by the small taper, so that the hemostatic part can effectively enter between the ulna and the radius to realize stable hemostasis, and the thickness of the hemostatic part can be effectively reduced to reduce the distance between the application and the skin of the wrist, and the hygiene performance of the wound is improved.

[0010] The height of the observation part is set to 5-7 mm to effectively control the magnification when the medical staff observes the wound through the observation part. If the height of the observation part continues to increase, the magnification of the observation part will also continue to increase, which may cause distortion of the wound observation, thereby causing misjudgment of the medical staff. At the same time, the higher the height, the thicker the thickness of the observation part, which may cause inconvenience when the patient wears a hospital gown in daily life. If the thickness of the observation part is thinner, the observation degree of the wound will be poor.

[0011] At the same time, the height of the observation part / hemostatic part continues to increase, which may cause difficulty in controlling the haze of the transparent body during the production process. Since the larger the taper, the greater the difference in cooling speed between the center and the periphery of the transparent body, the transparency of the transparent body may be reduced, thereby affecting the accuracy of observation.

[0012] At the same time, when the transparent body is cut along the width direction of the application, the length corresponding to the observation part corresponds to the length from the skin puncture wound (hereinafter referred to as the skin bleeding hole) to the subcutaneous blood vessel wall wound (hereinafter referred to as the subcutaneous bleeding hole) of the blood vessel puncture path. Since the inclination angle is generally 30-45 degrees during the interventional treatment puncture, when effective hemostasis of the wound is required, the hemostatic part needs to effectively cover the skin bleeding hole and the subcutaneous bleeding hole of the entire wound. The length of the hemostatic part is set to 32-40mm. Due to the existence of the interventional groove, the effective compression length is 16-20mm. Due to the height, the interval between the ulna and the radius and the depth of the radial artery are considered. Under this curvature, the normal pressure on the radial artery is 8-10mm. At this time, the part that can effectively compress and hemostasis the subcutaneous bleeding hole and the skin bleeding hole of the radial artery is the tip of the hemostatic part. The effective compression arc length is 4-5mm, which can effectively hemostasis under the condition of 30-45 degrees. If the length of the hemostatic part continues to increase, the effective compression length will indeed increase, but for the wound, it undoubtedly increases the useless compression length, that is, the cost of the transparent body. If the length of the hemostatic part is reduced, the skin bleeding hole or the subcutaneous bleeding hole cannot be effectively hemostasis. Therefore, by controlling the length of the hemostatic part to 32-40mm, effective hemostasis of the radial artery can be achieved while reducing the cost. At this time, the length of the observation part is determined by the length of the hemostatic part.

[0013] At the same time, through the interventional groove opened at the bottom of the transparent body, when the interventional tube is pulled out for hemostasis, the relevant medical staff first presses the transparent body against the interventional puncture site, aligns the puncture site of the interventional tube with the interventional groove, and then slowly pulls out the interventional tube, so that the transparent body stably presses the radial artery for hemostasis. The interventional groove is set to facilitate the fixation of the interventional tube, reduce the expansion of the wound caused by the medical staff pulling out the interventional tube, and improve the subsequent hemostasis effect. At the same time, the interventional groove serves as a mark for the correct direction of the hemostat.

[0014] At the same time, the suction accessory provided on the bottom side of the transparent body can absorb blood and tissue fluid at the wound, forming an "isolation zone" to further reduce the problem of infection caused by foreign matter or bacteria entering the wound through the interval between the application and the skin.

[0015] Meanwhile, through the fixing plate arranged around the periphery of the transparent body, when the radial artery is pressed and hemostasis is performed by wrapping the patch, the fixing plate is clamped with the transparent body to press the transparent body, so that the transparent body is uniformly pressed, the deviation of the transparent body caused by uneven pressing is reduced, the hemostasis effect is affected, meanwhile, the size of the transparent plate is set to be 1.5 times of the size of the transparent body, the gap problem caused by the size of the fixing plate being larger than the width of the wrist is reduced due to the size being too large, and the problem of the transparent body being unable to be uniformly pressed due to the size being too small is reduced.

[0016] Meanwhile, when the patch is removed after the wound is healed, the tearing feeling of the patch and the skin is reduced, so that the use feeling of the patient is improved.

[0017] Optionally, the release member includes a release part arranged on the patch and an adhesive layer arranged on the bottom side of the patch, the release part includes a plurality of air holes arranged on the patch, the air holes are arranged on both sides of the fixing plate, and the air holes are not provided with the adhesive layer.

[0018] By adopting the above technical scheme, the air holes and the release part are arranged, the air permeability of the patch during use is improved, the skin is not always covered by the patch, the skin is not soaked, the skin is not fragile, the tearing pain caused by removing the patch is reduced, and the comfort of the patient is improved.

[0019] Optionally, the absorbing member includes a non-woven fabric layer adhered to the bottom side of the transparent body, the non-woven fabric layer is adhered to the bottom side of the transparent body by pressure-sensitive adhesive, and the side of the non-woven fabric layer close to the opening end of the intervention groove is in an open shape.

[0020] By adopting the above technical scheme, the open non-woven fabric layer is arranged, the use direction is easily distinguished by the medical staff before use, the blood and body fluid are absorbed during use, and the subsequent observation and hemostasis are facilitated.

[0021] During hemostasis, the medical staff moves the hemostat to the intervention site, and exposes the skin bleeding point of the intervention wound at the opening of the non-woven fabric layer, that is, the recess of the non-woven fabric layer "M" is positioned.

[0022] Then, the medical staff slowly moves the hemostat until the skin bleeding point disappears from the opening area of the non-woven fabric layer, and the skin bleeding point cannot be observed from the other side of the non-woven fabric layer, which means that the skin bleeding point is completely covered on the bottom side of the non-woven fabric layer, and at the same time, it means that the effective pressing arc at the bottom of the hemostatic part can press and hemostasis the subcutaneous bleeding point, finally, the medical staff pulls out the intervention tube, presses the transparent body, tears off the release paper layer of the patch, and adheres the patch to the wrist of the patient, so that the transparent body stably presses and hemostasis the wound.

[0023] At the same time, the compatibility of the non-woven fabric layer with the skin is higher than that of the transparent silicone material with the skin, which is beneficial to wound healing.

[0024] Optionally, a clamping groove is arranged on one side of the fixing plate close to the intervention groove, the opening width of the clamping groove is consistent with the diameter of the intervention tube, and a fixing groove is arranged on the outer periphery of the transparent body, the fixing groove is arranged around the transparent body, and the fixing plate is clamped in the fixing groove.

[0025] By adopting the above technical scheme, the pulling-out direction of the intervention tube is fixed by the double limiting of the intervention groove and the clamping groove before use, so as to further reduce the increase of the wound caused by the deviation of the intervention tube during the pulling-out process, thereby reducing the amount of bleeding and facilitating subsequent hemostasis.

[0026] Optionally, the injection molding machine comprises a machine frame, a first fixed mold fixed on the machine frame, a second fixed mold slidingly arranged on the machine frame, and a third fixed mold slidingly arranged on the machine frame, the second fixed mold and the third fixed mold are arranged opposite to each other, the first fixed mold, the second fixed mold and the third fixed mold jointly form a molding cavity for molding the transparent body, the first fixed mold corresponds to the lower half of the hemostatic part, the second fixed mold and the third fixed mold correspond to the upper half of the hemostatic part and the observation part, the second fixed mold and the third fixed mold are arranged symmetrically relative to each other, and the second fixed mold and the third fixed mold are both provided with a spraying assembly for spraying a releasing agent in the inner cavity.

[0027] By adopting the above technical scheme, since the transparent body needs to ensure stable hemostasis and clear observation during the design process, the haze of the transparent body also needs to be accurately controlled, and since the transparent body is injection molded, in order to improve the observation degree, it is necessary to ensure that there is no splicing seam in the middle position of the hemostatic part, and in the prior art, the splicing seam is often removed by grinding, which still affects the observation degree, and the splicing seam affects the healing of the wound during the pressing hemostasis of the transparent body and reduces the comfort of the patient, therefore, in the scheme of the present application, the mold is divided into three groups, the splicing seam at the bottom side of the hemostatic part is shifted from the middle position to the two sides, and the splicing seams on the two sides are covered by the non-woven fabric layer, thereby reducing the discomfort of the patient caused by the splicing seam, and not affecting the observation degree of the medical staff.

[0028] At the same time, the spraying assembly is further arranged to reduce the adhesion between the transparent body and the mold during the demolding process, thereby improving the surface quality of the transparent body and the surface haze of the transparent body.

[0029] Optionally, the second fixed mold and the third fixed mold correspond to the position of the fixed groove are provided with fixed blocks, the fixed blocks protrude from the inner wall of the second fixed mold / third fixed mold, the spraying assembly comprises a liquid storage tank arranged on the second fixed mold / third fixed mold, the fixed blocks are provided with spraying ports, the spraying ports are provided with two groups, each group of the spraying ports comprises two spraying ports oppositely arranged on the fixed blocks, the second fixed mold and the third fixed mold are provided with temporary storage cavities, the temporary storage cavities are in communication with the liquid storage tank, and the temporary storage cavities are provided with the amount of release agent for next time spraying on the inner wall of the second fixed mold / third fixed mold.

[0030] By adopting the above technical scheme, the position of the fixed groove is corresponded by the fixed blocks, and the fixed blocks protrude from the inner surface of the second fixed mold and the third fixed mold, so that the spraying ports provided on the fixed blocks facilitate the spraying of the release agent on the second fixed mold and the third fixed mold. Since the fixed groove is only used to realize the clamping of the fixed plate and the transparent body, the haze at the fixed groove is not affected, so the main spraying part is arranged at the fixed block, which greatly improves the control of the haze on the surface of the transparent body, thereby facilitating the observation of the medical staff on the wound.

[0031] Optionally, the first fixed mold is provided with a positioning block corresponding to the clamping groove, a first temperature sensor is embedded in the inner circumferential wall of the first fixed mold, and a second temperature sensor is fixedly embedded in the positioning block. The second fixed mold and the third fixed mold are provided with cooling flow channels, and the second fixed mold and the third fixed mold are provided with an adjusting assembly for adjusting the flow rate of the cooling liquid in the temporary storage cavity and the cooling flow channel. When the value of the first temperature sensor is less than the temperature value of the second temperature sensor, it indicates that the cooling speed of the outer part of the transparent body is much greater than the cooling speed of the heart part of the transparent body, the adjusting assembly increases the amount of release agent in the temporary storage cavity, and reduces the flow rate of the cooling flow channel. When the value of the first temperature sensor is greater than the temperature value of the second temperature sensor, it indicates that the cooling speed of the outer part of the transparent body is less than the cooling speed of the heart part of the transparent body, the adjusting assembly reduces the amount of release agent in the temporary storage cavity, and increases the flow rate of the cooling flow channel.

[0032] By adopting the technical scheme, since the intervention groove plays a positioning role on the intervention pipe and does not mainly play an observation role, the positioning block is arranged as a structure for measuring the temperature of the heart of the transparent body, that is, by comparing the temperature of the outer peripheral wall and the heart of the transparent body, the cooling rate inside and outside the transparent body is determined, when the temperature of the heart is relatively high, the flow rate in the cooling flow channel is reduced, the external cooling efficiency is reduced, the amount of the release agent is increased, the cooling efficiency of the second fixed mold and the third fixed mold on the outside of the transparent body is reduced, and the adhesion between the transparent body and the second fixed mold and the third fixed mold is reduced by increasing the release agent.

[0033] Meanwhile, when the value of the first temperature sensor is greater than the temperature value of the second temperature sensor, it indicates that the cooling speed of the outside of the transparent body is less than the cooling speed of the heart of the transparent body, so the flow rate of the cooling flow channel is increased, the cooling speed of the outside of the transparent body is increased, and the amount of the release agent is reduced.

[0034] Optionally, a piston plate is slidably arranged in the temporary storage cavity, the piston plate divides the temporary storage cavity into a buffer cavity and a liquid outlet cavity, the buffer cavity is in communication with the liquid storage tank, the liquid outlet cavity is in communication with the liquid outlet, a one-way structure is arranged on the piston plate to allow the release agent to flow from the buffer cavity to the liquid outlet cavity in one direction, and a one-way structure is arranged at the communication position between the buffer cavity and the liquid storage tank to allow the release agent to flow from the liquid storage tank to the buffer cavity in one direction, and a buffer block is slidably arranged in the first fixed mold and the second fixed mold, and the buffer block movably blocks the spraying port.

[0035] By adopting the technical scheme, when the transparent body is injection molded, the piston plate is arranged to slide in the second fixed mold and the third fixed mold away from each other, the piston plate in the second fixed mold slides towards the inner peripheral wall of the second fixed mold, so that the release agent in the liquid outlet cavity is extruded through the spraying hole, and the release agent in the liquid storage tank is extruded into the buffer cavity, and the piston plate in the third fixed mold slides towards the inner peripheral wall of the third fixed mold to spray the release agent on the second fixed mold and the third fixed mold.

[0036] Meanwhile, when the second fixed mold and the third fixed mold slide towards each other, the piston plate in the second fixed mold slides away from the inner peripheral wall of the second fixed mold to extrude the release agent in the buffer cavity into the liquid outlet cavity, which is convenient for the next spraying.

[0037] Meanwhile, by arranging the buffer block, the spraying hole is blocked when the second fixed mold and the third fixed mold slide towards each other, and the spraying hole is opened when the second fixed mold and the third fixed mold slide away from each other.

[0038] Optionally, the positioning block is slidingly arranged on the first fixed mold, and the positioning block is arranged on the inner circumferential wall of the first fixed mold in a movable manner, the first fixed mold is internally provided with a positioning rod and a sliding rod slidingly arranged in the positioning rod, the sliding rod is elastically slidingly arranged on the positioning rod, the first fixed mold is internally provided with an adjusting gear arranged in a rotating manner, the sliding rod is engaged with the adjusting gear, and the first fixed mold is further slidingly provided with a first linkage rod, the first linkage rod is engaged with the adjusting gear, and the first linkage rod is connected with the second fixed mold / third fixed mold.

[0039] By adopting the technical scheme, after injection molding is completed, in the process that the second fixed mold and the third fixed mold move close to or away from each other, the first linkage rod is driven to move away, the first linkage rod drives the adjusting gear to rotate, and the sliding of the positioning rod and the sliding rod is driven.

[0040] In the process that the second fixed mold and the third fixed mold move close to each other, the first linkage rod drives the adjusting gear to rotate, the sliding rod is driven to descend, the sliding rod drives the spring to stretch first when descending, and the positioning rod is driven to descend, until the positioning block descends to the injection position.

[0041] In the process that the second fixed mold and the third fixed mold move away from each other, the first linkage rod drives the adjusting gear to rotate, and the sliding rod is driven to ascend, the spring is relaxed first in the process that the sliding rod ascends, until the second fixed mold and the third fixed mold are separated from the transparent body, and in the process that the sliding rod continues to ascend, the spring is compressed and the positioning block is ejected, so that the transparent body is demolded.

[0042] To sum up, the present application has at least one of the following beneficial technical effects: 1. By controlling the size of the observation part and the hemostasis part of the transparent body, the hemostasis effect is improved, the observation degree of medical staff is improved, the size of the transparent body does not affect the actual use of the patient, and the comfort of the patient is improved. 2.

DETAILED DESCRIPTION

[0045] The following will be described in detail in combination with the accompanying drawings Figures 1-4 The application will be further described in detail.

[0046] The embodiment provides a radial artery hemostat, which comprises a patch 1 and a fixed plate 11 fixed to the patch 1. The patch 1 serves as a basic support structure and provides a carrier for the hemostat to be attached to the skin; and the fixed plate 11 serves to fix and support a transparent body 12. In the application, the transparent body 12 is made of liquid silicone, so as to be transparent and non-toxic, and facilitate the use of medical staff in clinical practice.

[0047] A fixed hole is formed in the middle of the fixed plate 11. The fixed hole not only provides a positioning space for the installation of the transparent body 12, but also reduces the weight of the fixed plate 11 to some extent, so that the overall structure is more portable. The transparent body 12 is fixedly embedded at the middle position of the fixed plate 11. The transparent body 12 is a non-rotating body structure arranged symmetrically. This special structure is to better adapt to the physiological characteristics of the wrist part of the human body and realize stable hemostasis.

[0048] The transparent body 12 is divided into an observation part 13 and a hemostasis part 14 by the fixed plate 11. The observation part 13 is located on the side of the fixed plate 11 away from the skin, so that medical staff can clearly observe the bleeding condition at the wound and timely adjust the hemostasis measures. The hemostasis part 14 is located on the side of the fixed plate 11 close to the skin and directly contacts the wound, thereby playing a role in compression hemostasis.

[0049] It should be noted that the haze of the transparent body 12 is less than 5%, and in clinical use, medical staff need to accurately observe the situation at the wound site, such as the amount of bleeding, color change, etc. through the transparent body 12. If the haze of the transparent body 12 is too high, it will lead to unclear observation, affecting the judgment of medical staff on the patient's condition, thereby delaying the treatment opportunity. The low haze design of the transparent body 12 in the embodiment ensures that medical staff can clearly see the wound situation, providing a strong guarantee for timely and accurate treatment.

[0050] The bottom side of the transparent body 12 is provided with an intervention groove 15, which is perpendicular to the length direction of the patch 1, and one side of the intervention groove 15 is in an open state. When performing the pull-out hemostasis operation of the intervention tube, the medical staff first presses the transparent body 12 against the intervention puncture site, so that the puncture site of the intervention tube is aligned with the intervention groove 15, and the intervention tube corresponds to the intervention groove 15. Then slowly pull out the intervention tube, at this time the transparent body 12 can stably press and stop bleeding of the radial artery. The setting of the intervention groove 15 not only facilitates the fixation of the intervention tube, reduces the risk of wound enlargement caused by the deviation of the intervention tube during operation of the medical staff, and improves the subsequent hemostasis effect, but also serves as a marker for the front and back directions of the hemostat during use, facilitating the rapid and accurate use of medical staff.

[0051] When the transparent body 12 is cut in half along the length direction of the patch 1, the length of the observation part 13 / hemostatic part 14 is 16-20mm, and the height of the observation part 13 is 5-7mm. Specifically, the cross section of the observation part 13 along the length direction of the patch 1 is a half-elliptical shape with a long side of 8-10mm and a short side of 7.5-9.5mm; the cross section of the hemostatic part 14 along the length direction of the patch 1 is a half-elliptical shape with a long side of 8-10mm, a short side of 7.5-9.5mm, and a height of 5.5-8.5mm.

[0052] Because in clinical application, the length corresponding to the arc surface of the hemostatic part 14 is closely related to the distance between the radius and ulna at the wrist of the human body. Generally, when performing an interventional operation, the interventional site is located at the radial artery of the wrist, and the distance between the ulna and radius of the human body is 8-12 mm. Controlling the length of the arc surface of the hemostatic part 14 to be 16-20 mm can not only realize stable hemostasis when the transparent body 12 is inserted between the ulna and radius, but also reduce the problem of excessive distance between the patch 1 and the skin of the wrist when the size of the transparent body 12 is too large. If the distance is too large, foreign matter or bacteria can easily enter through the gap between the patch 1 and the skin, causing wound infection. At the same time, controlling the height of the short side of the hemostatic part 14 to be 7.5-9.5 mm makes the curvature of the contact part of the hemostatic part 14 with the skin match the curvature after pressing. In this way, while stable hemostasis is realized on the radial artery, the compression on other surrounding blood vessels caused by excessive taper can be reduced, and the comfort of the patient can be improved; the thickness of the hemostatic part 14 can also be effectively reduced, the distance between the patch 1 and the skin of the wrist can be reduced, and the hygiene performance of the wound can be improved.

[0053] Setting the height of the observation part 13 to be 5-7 mm can effectively control the magnification when medical staff observes the wound through the observation part 13. If the height of the observation part 13 continues to increase, the magnification of the observation part 13 will also continue to increase, which can easily cause distortion of the wound observation, thereby possibly leading to misjudgment by medical staff. Moreover, the higher the height, the thicker the thickness of the observation part 13, and the patient will feel inconvenient when wearing a hospital gown in daily life. If the thickness of the observation part 13 is too thin, the observation degree of the wound will be affected. At the same time, when the height of the observation part 13 / hemostatic part 14 continues to increase, it is easy to cause difficulty in haze control of the transparent body 12 in the production process. Because the larger the taper, the greater the difference in cooling speed between the center and the periphery of the transparent body 12, which can easily cause the transparency of the transparent body 12 to decrease, thereby affecting the accuracy of observation.

[0054] When the transparent body 12 is cut in half along the width direction of the patch 1, the length of the observation part 13 / hemostatic part 14 is 32-40 mm. That is, the cross section of the observation part 13 along the width direction of the patch 1 is a half-ellipse with a long side of 16-20 mm and a short side of 5-7 mm; the cross section of the hemostatic part 14 along the width direction of the patch 1 is a half-ellipse with a long side of 16-20 mm and a short side of 7.5-9.5 mm.

[0055] When the patch 1 is cut along the width direction, the length corresponding to the observation part 13 corresponds to the length of the intervention wound. When the intervention treatment puncture is performed, the inclination angle is generally 30-45 degrees. In order to effectively stop bleeding of the wound, the compression of the radial artery by the hemostasis part 14 needs to effectively cover the entire wound. The length of the hemostasis part 14 is set to 32-40 mm, and due to the intervention groove 15, the effective compression length is 16-20 mm. The height is set to take into account the distance between the ulna and the radius and the depth of the radial artery. At this time, the height of the hemostasis part 14 is fixed. Under this curvature, the normal pressure on the radial artery is 8-10 mm, which can effectively stop bleeding of the wound of the radial artery. If the length of the hemostasis part 14 continues to increase, the effective compression length can indeed be increased, but for the wound, it will increase the useless compression length, that is, increase the cost of the transparent body 12. If the length of the hemostasis part 14 is reduced, effective hemostasis cannot be achieved. Therefore, by controlling the length of the hemostasis part 14 to be 32-40 mm, effective compression hemostasis of the radial artery can be achieved while reducing the cost, and the length of the observation part 13 is determined by the length of the hemostasis part 14.

[0056] The size of the fixed plate 11 along the length direction of the patch 1 is 1.5 times the size of the transparent body 12 along the length direction of the patch 1, and the size along the width direction of the patch 1 is 1.5 times the size of the transparent body 12 along the width direction of the patch 1. When the patch 1 is wrapped around the radial artery to compress and stop bleeding, the fixed plate 11 is clamped with the transparent body 12 to press the transparent body 12, so that the transparent body 12 is uniformly pressed, and the offset of the transparent body 12 caused by uneven pressing is reduced, which affects the hemostasis effect. The size of the fixed plate 11 is set to be 1.5 times the size of the transparent body 12, which can avoid the problem of gap caused by the fixed plate 11 being larger than the width of the wrist due to too large size, and can prevent the problem of uneven pressing of the transparent body 12 caused by too small size.

[0057] The patch 1 also has a detachment part 2 for taking off the hemostat. The detachment part 2 includes a release part 21 provided on the patch 1 and an adhesive layer 17 provided on the bottom side of the patch 1. The release part 21 includes a plurality of air holes 22 provided on the patch 1, and the air holes 22 are provided on both sides of the fixed plate 11, and the air holes 22 are not provided with the adhesive layer 17. When the patch 1 is taken off after the wound is healed, the release part 21 and the air holes 22 can improve the air permeability of the patch 1 in use. The skin is covered by the patch 1 for a long time, which can cause skin maceration, resulting in fragile skin. The design of the air holes 22 can reduce this situation, thereby reducing the tearing pain when the patch 1 is removed, and improving the comfort of the patient.

[0058] The bottom side of the transparent body 12 is also provided with an absorbing member 3 for absorbing blood and body fluid at the wound site. The absorbing member 3 includes a non-woven fabric layer 31 attached to the bottom side of the transparent body 12. The non-woven fabric layer 31 is attached to the bottom side of the transparent body 12 by pressure-sensitive adhesive, and the side of the non-woven fabric layer 31 near the opening end of the intervention groove 15 is open. As shown in Figs. 3 and 4, the non-woven fabric layer 31 is in the shape of "M". The non-woven fabric layer 31 can absorb blood and tissue fluid at the wound site, forming an "isolation zone", and further reducing the problem of infection caused by foreign matter or bacteria entering the wound site through the gap between the dressing 1 and the skin. At the same time, the open non-woven fabric layer 31 is easy for medical staff to distinguish the direction of use before use, and can absorb blood and body fluid during use, which is convenient for subsequent observation and hemostasis. Figure 1 and Figs. Figure 2 As shown in Figs. 3 and 4, the non-woven fabric layer 31 is in the shape of "M". The non-woven fabric layer 31 can absorb blood and tissue fluid at the wound site, forming an "isolation zone", and further reducing the problem of infection caused by foreign matter or bacteria entering the wound site through the gap between the dressing 1 and the skin. At the same time, the open non-woven fabric layer 31 is easy for medical staff to distinguish the direction of use before use, and can absorb blood and body fluid during use, which is convenient for subsequent observation and hemostasis.

[0059] The fixing plate 11 is provided with a clamping groove 18 on the side near the intervention groove 15, and the opening width of the clamping groove 18 is consistent with the diameter of the intervention tube. The transparent body 12 is provided with a fixing groove 16 on the outer circumferential side, and the fixing plate 11 is clamped in the fixing groove 16. Before use, the intervention tube can be fixed in the pulling-out direction by double limiting of the intervention groove 15 and the clamping groove 18, so as to further reduce the increase of the wound caused by the deviation of the intervention tube during pulling-out, reduce the amount of bleeding, and facilitate subsequent hemostasis.

[0060] In the embodiment of the present application, the utility method for a radial artery hemostat is as follows. First, the medical staff moves the hemostat to the intervention site, and exposes the skin bleeding point of the intervention wound at the opening of the non-woven fabric layer 31, i.e., the recess of the "M"-shaped non-woven fabric layer 31, to complete positioning.

[0061] Then, the medical staff slowly moves the hemostat until the skin bleeding point disappears from the opening area of the non-woven fabric layer 31, and the skin bleeding point cannot be observed from the other side of the non-woven fabric layer 31. At this time, it means that the skin bleeding point on the bottom side of the non-woven fabric layer 31 is completely covered, and it also means that the effective pressure of the bottom of the hemostatic part 14 can press and hemostasis the subcutaneous bleeding point. Finally, the medical staff pulls out the intervention tube while pressing the transparent body 12, tears off the release paper layer of the dressing 1, and sticks the dressing 1 to the wrist of the patient, so as to realize stable pressure hemostasis of the transparent body 12 to the wound site.

[0062] The embodiment also provides a production device for producing the radial artery hemostat transparent body 12, which comprises an injection molding machine frame 4, a first fixed mold 41 fixed on the frame 4, a second fixed mold 42 slidingly arranged on the frame 4, and a third fixed mold 43 slidingly arranged on the frame 4. The second fixed mold 42 and the third fixed mold 43 are arranged opposite to each other, and the first fixed mold 41, the second fixed mold 42, and the third fixed mold 43 enclose a molding cavity 44 for molding the transparent body 12. The first fixed mold 41 corresponds to the lower half of the hemostatic part 14, the second fixed mold 42 and the third fixed mold 43 correspond to the upper half of the hemostatic part 14 and the observation part 13, and the second fixed mold 42 and the third fixed mold 43 are arranged symmetrically relative to each other.

[0063] Since the transparent body 12 needs to ensure stable hemostasis and clear observation during the design process, the haze of the transparent body 12 needs to be accurately controlled. At the same time, the middle position of the hemostatic part 14 of the transparent body 12 corresponds to the wound during the design process, and the transparent body 12 is injection molded. In order to improve the observation, it is necessary to ensure that there is no splicing seam at the middle position of the hemostatic part 14. In the prior art, the splicing seam is often removed by grinding, but the grinding method still affects the observation, and the splicing seam affects the healing of the wound during the pressing hemostasis of the transparent body 12 and reduces the comfort of the patient. The embodiment divides the mold into three groups, and moves the splicing seam at the bottom side of the hemostatic part 14 from the middle position to the two sides. The splicing seams on the two sides are covered by the non-woven fabric layer 31, thereby reducing the discomfort of the patient caused by the splicing seam, and not affecting the observation of the medical staff.

[0064] The second fixed mold 42 and the third fixed mold 43 are each provided with a spraying assembly 5 for spraying a releasing agent in the inner cavity. The second fixed mold 42 and the third fixed mold 43 are each provided with a fixed block 51 corresponding to the position of the fixed groove 16, and the fixed block 51 protrudes from the inner wall of the second fixed mold 42 / third fixed mold 43. The spraying assembly 5 comprises a liquid storage tank 52 arranged on the second fixed mold 42 / third fixed mold 43, and the fixed block 51 is provided with two groups of spraying openings 53. Each group of spraying openings 53 comprises two spraying openings 53 arranged opposite to each other on the fixed block 51. The second fixed mold 42 and the third fixed mold 43 are each provided with a temporary storage cavity 54 in communication with the liquid storage tank 52, and the temporary storage cavity 54 is provided with a quantity of releasing agent for next time spraying the inner wall of the second fixed mold 42 / third fixed mold 43.

[0065] The fixed block 51 is arranged corresponding to the position of the fixed groove 16, and protrudes from the inner surface of the second fixed die 42 and the third fixed die 43. The spraying port 53 arranged on the fixed block 51 facilitates spraying of the release agent on the second fixed die 42 and the third fixed die 43. Since the fixed groove 16 is only used to realize the clamping of the fixed plate 11 and the transparent body 12, the haze at the fixed groove 16 is not affected, and the main part to be sprayed is arranged at the fixed block 51, which greatly improves the control of the haze on the surface of the transparent body 12, thereby facilitating the observation of the medical staff on the wound.

[0066] The first fixed die 41 is provided with a positioning block 55 corresponding to the clamping groove 18, and the inner peripheral wall of the first fixed die 41 is embedded with a first temperature sensor 57, and the positioning block 55 is embedded with a second temperature sensor 58. The second fixed die 42 and the third fixed die 43 are provided with a cooling flow channel 56, and the second fixed die 42 and the third fixed die 43 are provided with an adjusting assembly for adjusting the flow rate of the cooling liquid in the temporary storage cavity 54 and the cooling flow channel 56.

[0067] When the value of the first temperature sensor 57 is less than the temperature value of the second temperature sensor 58, it indicates that the cooling speed of the outside of the transparent body 12 is much greater than the cooling speed of the center of the transparent body 12. The adjusting assembly increases the amount of release agent in the temporary storage cavity 54 and reduces the flow rate of the cooling flow channel 56. Since the intervention groove 15 serves to position the intervention tube and does not mainly serve to observe, the positioning block 55 is arranged to measure the temperature of the center of the transparent body 12. By comparing the temperature of the outer peripheral wall and the center of the transparent body 12, the cooling rate of the inside and outside of the transparent body 12 can be determined. When the temperature of the center is high, the flow rate of the cooling flow channel 56 is reduced, thereby reducing the external cooling efficiency, and the amount of release agent is increased, thereby reducing the cooling efficiency of the second fixed die 42 and the third fixed die 43 on the outside of the transparent body 12, and the adhesion between the transparent body 12 and the second fixed die 42 and the third fixed die 43 is reduced by increasing the release agent.

[0068] When the value of the first temperature sensor 57 is greater than the temperature value of the second temperature sensor 58, it indicates that the cooling speed of the outside of the transparent body 12 is less than the cooling speed of the center of the transparent body 12, and the adjusting assembly reduces the amount of release agent in the temporary storage cavity 54 and increases the flow rate of the cooling flow channel 56, thereby improving the cooling speed of the outside of the transparent body 12.

[0069] The piston plate 6 is slidably arranged in the temporary storage cavity 54, and the piston plate 6 divides the temporary storage cavity 54 into a buffer cavity 61 and a liquid outlet cavity 62. The buffer cavity 61 is in communication with the liquid storage tank 52, and the liquid outlet cavity 62 is in communication with a liquid outlet. The piston plate 6 is provided with a one-way structure 64 for allowing the release agent to flow from the buffer cavity 61 to the liquid outlet cavity 62 in one direction. The communication position of the buffer cavity 61 and the liquid storage tank 52 is also provided with a one-way structure 64 for allowing the release agent to flow from the liquid storage tank 52 to the buffer cavity 61 in one direction. Meanwhile, the first fixed mold 41 and the second fixed mold 42 are both slidably provided with a buffer block 63, and the buffer block 63 movably blocks the spraying hole 53.

[0070] When the second fixed mold 42 and the third fixed mold 43 are slid away from each other during the injection molding of the transparent body 12, the piston plate 6 in the second fixed mold 42 slides towards the inner wall of the second fixed mold 42, so as to extrude the release agent in the liquid outlet cavity 62 through the spraying hole, and at the same time, the release agent in the liquid storage tank 52 is extruded into the buffer cavity 61. At the same time, the piston plate 6 in the third fixed mold 43 slides towards the inner wall of the third fixed mold 43, and the second fixed mold 42 and the third fixed mold 43 are sprayed with the release agent.

[0071] When the second fixed mold 42 and the third fixed mold 43 are slid towards each other, the piston plate 6 in the second fixed mold 42 slides away from the inner wall of the second fixed mold 42, and the release agent in the buffer cavity 61 is extruded into the liquid outlet cavity 62, facilitating the next spraying. At the same time, the buffer block 63 is arranged to block the spraying hole when the second fixed mold 42 and the third fixed mold 43 are slid towards each other, and to open the spraying hole when the second fixed mold 42 and the third fixed mold 43 are slid away from each other.

[0072] The positioning block 55 is slidably arranged on the first fixed mold 41, and the positioning block 55 protrudes from the inner wall of the first fixed mold 41. The first fixed mold 41 is provided with a positioning rod and a sliding rod 7 slidably arranged in the positioning rod. The sliding rod 7 is elastically slidably arranged on the positioning rod. The first fixed mold 41 is rotatably provided with an adjusting gear 72, and the sliding rod 7 is engaged with the adjusting gear 72. The first fixed mold 41 is also slidably provided with a first linkage rod 73, and the first linkage rod 73 is engaged with the adjusting gear 72. At the same time, the first linkage rod 73 is connected with the second fixed mold 42 / third fixed mold 43.

[0073] During the process of moving the second fixed mold 42 and the third fixed mold 43 towards / away from each other after the injection molding is completed, the first linkage rod 73 is driven to move away, the first linkage rod 73 drives the adjusting gear 72 to rotate, thereby driving the positioning rod and the sliding rod 7 to slide.

[0074] In the process of the second fixed mold 42 and the third fixed mold 43 moving close to each other, the first linkage rod 73 drives the adjusting gear 72 to rotate, and drives the sliding rod 7 to descend. When the sliding rod 7 descends, it first drives the spring to stretch, and drives the positioning rod to descend, until it descends to the lowest point. At this time, the positioning block 55 descends to the position of injection molding.

[0075] In the process of the second fixed mold 42 and the third fixed mold 43 moving away from each other, the first linkage rod 73 drives the adjusting gear 72 to rotate, and drives the sliding rod 7 to ascend. At this time, in the process of the sliding rod 7 ascending, it first relaxes the spring, until the second fixed mold 42 and the third fixed mold 43 are separated from the transparent body 12. In the process of the sliding rod 7 continuing to ascend, it drives the spring to compress and eject the positioning block 55, so as to realize the demolding of the transparent body 12.

[0076] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
