Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an ice pack device after coronary angiography. Background Technology

[0002] Clinically, when performing coronary angiography, the radial artery at the wrist is usually selected as the puncture point. Applying ice to the puncture site after radial artery puncture is an important postoperative care measure. Its core purpose is to promote hemostasis, reduce discomfort, and prevent complications.

[0003] Currently, when applying ice to the puncture site, the commonly used method is intermittent ice application. This means that the duration of each ice application is usually controlled to be around 15-20 minutes, and there is a period of time between each application to prevent frostbite of the skin and tissues and allow the skin and tissues time to recover. Typically, the interval is at least 1 hour.

[0004] However, in the actual process of applying ice to the puncture site, the inventors discovered that the current ice application method still has shortcomings, specifically:

[0005] Normally, the ice pack should be removed from the puncture site after each application to prevent it from remaining on the site. This means that both the patient and healthcare professionals need to monitor the duration of ice application to avoid prolonged application. However, when the patient is asleep while receiving ice, or when hospital staff are short-staffed and cannot immediately monitor the patient's ice application, over-icing can easily occur, leading to prolonged application and potentially causing frostbite to the skin and tissues.

[0006] Therefore, how to avoid over-icing and frostbite of the skin and tissues when a patient is asleep while receiving ice application and the hospital is short-staffed and unable to pay attention to the patient's ice application status immediately is a technical problem that urgently needs to be solved. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of current methods for applying ice to the puncture site of patients by providing a post-coronary angiography ice application device. This device aims to prevent excessive ice application and frostbite to the skin and tissues when the patient is asleep while receiving ice application and when hospital staff are short-staffed and cannot immediately monitor the patient's ice application.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] A post-coronary angiography ice pack device includes an ice pack assembly for applying ice to the puncture site of a patient. The ice pack assembly includes a first cylinder and a second cylinder, with the first cylinder fitted inside the second cylinder to allow it to move along the length of the second cylinder. A first baffle is formed on the first cylinder, dividing the space inside the second cylinder into a first chamber and a second chamber. The first chamber is closed. The second cylinder is provided with a vent and a switch. The vent communicates with the first chamber, and the switch controls the size of the vent. An air hole is provided at the bottom of the second cylinder for gas to penetrate the bottom of the second cylinder.

[0010] A return spring is connected between the first cylinder and the second cylinder. The return spring is elastic. When the return spring is in the initial state, the return spring provides elastic force to keep the first cylinder away from the bottom of the second cylinder.

[0011] The first cylinder is used to store the cooling medium.

[0012] As a preferred technical solution of this application, when the first cylinder moves relative to the second cylinder, the minimum distance between the bottoms of the first cylinder and the second cylinder is a, where a≤5mm.

[0013] As the preferred technical solution of this application, the switch has a blocking part formed on it, and the switch is rotatably connected to the second cylinder. By rotating the switch relative to the second cylinder, the area blocked by the blocking part of the vent is adjusted, thereby controlling the size of the vent.

[0014] As the preferred technical solution of this application, the shielding part can completely block the vent, thereby sealing the vent.

[0015] As the preferred technical solution of this application, the reset spring is located in the first chamber, one end of the reset spring is connected to the first baffle, and the other end is connected to the second cylinder.

[0016] As the preferred technical solution of this application, the first cylinder is provided with a liquid injection port, through which the cooling medium can be injected into the first cylinder, and the liquid injection port is adapted to a cover.

[0017] As the preferred technical solution of this application, the bottom of the second cylinder is provided with a number of air holes, so that the bottom of the second cylinder is hollow.

[0018] As a preferred technical solution of this application, the post-coronary angiography ice pack device further includes a restraint strap and a base. The ice pack component is disposed on the base, and the restraint strap is used to restrain the base to the patient's limb so that the ice pack component applies pressure to the patient's puncture site.

[0019] As the preferred technical solution of this application, the second cylinder is rotatably connected to the base. By rotating the second cylinder relative to the base, the second cylinder moves relative to the base along its own length direction, thereby adjusting the pressure applied by the bottom of the second cylinder to the patient's puncture site.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. In the scheme of this application, when applying ice to the patient's puncture site, the cooling medium, which can be ice or ice water, is first stored in the first cylinder, and the first cylinder is positioned close to the bottom of the second cylinder. In this state, after the patient wears the post-coronary angiography ice application device, the first cylinder and the cooling medium are closer to the puncture site, and the return spring is in a state of large deformation. Then, by adjusting the switch to control the size of the ventilation port, and as the return spring gradually recovers its deformation, the speed at which gas in the first chamber leaks out of the ventilation port can be controlled, as well as the speed at which the first cylinder moves relative to the second cylinder. In this way, the first cylinder gradually moves away from the bottom of the second cylinder, thereby gradually weakening the ice application effect of the cooling medium on the patient's puncture site, thus making the coronary angiography device of this application more effective. The ice-cold compress device provided by the post-angiography ice pack gradually weakens over time, and the rate of weakening can be controlled by adjusting the size of the ventilation port. This allows the device to provide the best ice-cold compress effect within 10-20 minutes, and the effect to significantly decrease after 20 minutes. At this point, because the first cylinder and cooling medium are far from the puncture site (e.g., 6cm), the ice-cold compress effect is weak or even negligible, thus avoiding frostbite to the skin and tissues. In this way, when the patient is asleep while receiving ice packs and there is a shortage of medical staff in the hospital, preventing them from paying attention to the patient's ice pack status immediately, over-ice packing and frostbite to the skin and tissues can be avoided.

[0022] 2. Meanwhile, gas exchange between the second chamber and the external environment relies on the pores at the bottom of the second cylinder. As the first cylinder gradually moves away from the puncture site, the space of the second chamber gradually increases, allowing gas from the external environment to enter the second chamber through the pores at the bottom of the second cylinder. The bottom of the second cylinder is usually in contact with the dressing on the puncture site. In this way, while ensuring that gas from the external environment can smoothly enter the second chamber, the airflow around the dressing can be accelerated, the sweat at the puncture site covered by the dressing can be evaporated more quickly, which helps to keep the skin dry and improves patient comfort.

[0023] 3. By making the bottom of the second cylinder hollow, the air permeability of the bottom of the second cylinder is further improved;

[0024] 4. By rotatably connecting the second cylinder to the base, when the second cylinder rotates relative to the base, it can rotate relative to the base along its own length direction, thereby facilitating the adjustment of the pressure applied by the bottom of the second cylinder to the patient's puncture site, thus improving the convenience of applying pressure to the puncture site.

These terms are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] Example 1: This example provides an ice pack device for post-coronary angiography, see [link to example]. Figures 1-3 As shown, the device includes an ice pack assembly 1, which is used to apply ice to the puncture site of the patient. The ice pack assembly 1 includes a first cylinder 2 and a second cylinder 3. The first cylinder 2 is fitted inside the second cylinder 3, allowing the first cylinder 2 to move along the length of the second cylinder 3. A first baffle 4 is formed on the first cylinder 2, which divides the space inside the second cylinder 3 into a first chamber 5 and a second chamber 6. The first chamber 5 is closed. A vent 7 and a switch 8 are provided on the second cylinder 3. The vent 7 communicates with the first chamber 5, and the switch 8 is used to control the size of the vent 7. An air hole 9 is provided at the bottom of the second cylinder 3, which allows gas to penetrate the bottom of the second cylinder 3.

[0035] A return spring 10 is connected between the first cylinder 2 and the second cylinder 3. The return spring 10 is elastic. When the return spring 10 is in the initial state, the return spring 10 provides elastic force to keep the first cylinder 2 away from the bottom of the second cylinder 3.

[0036] The first cylinder 2 is used to store the cooling medium.

[0037] In this application, when applying ice to the patient's puncture site, the cooling medium, which can be ice or ice water, is first stored in the first cylinder 2, and the first cylinder 2 is positioned close to the bottom of the second cylinder 3. In this state, after the patient wears the post-coronary angiography ice application device, the first cylinder 2 and the cooling medium are closer to the puncture site, and the return spring 10 is in a state of significant deformation. Then, by adjusting the switch 8, the size of the vent 7 is controlled. As the return spring 10 gradually recovers its deformation, the speed at which gas in the first chamber 5 leaks out of the vent 7 can be controlled, as well as the speed at which the first cylinder 2 moves relative to the second cylinder 3. In this way, the first cylinder 2 gradually moves away from the bottom of the second cylinder 3, thereby gradually weakening the ice application effect of the cooling medium on the patient's puncture site. Thus, this application... The ice pack effect provided by the post-coronary angiography ice pack device gradually weakens over time, and the rate of weakening can be controlled by adjusting the size of the ventilation port 7. This allows the device to provide the best ice pack effect within 10-20 minutes, and the effect to significantly decrease after 20 minutes. At this point, because the first cylinder 2 and the cooling medium are far from the puncture site (e.g., 6cm), the ice pack effect is weak or even negligible, thus avoiding frostbite to the skin and tissues. In this way, when the patient is asleep while receiving ice packs and there is a shortage of medical staff in the hospital, preventing them from paying attention to the patient's ice pack status immediately, over-ice packing and frostbite to the skin and tissues can be avoided.

[0038] Meanwhile, gas exchange between the second chamber 6 and the external environment relies on the air vent 9 at the bottom of the second cylinder 3. As the first cylinder 2 gradually moves away from the puncture site, the space of the second chamber 6 gradually increases, allowing gas from the external environment to enter the second chamber 6 through the air vent 9 at the bottom of the second cylinder 3. The bottom of the second cylinder 3 is usually in contact with the dressing on the puncture site. In this way, while ensuring that gas from the external environment can smoothly enter the second chamber 6, the airflow around the dressing can be accelerated, the sweat at the puncture site covered by the dressing can be evaporated more quickly, which helps to keep the skin dry and improves patient comfort.

[0039] As a preferred embodiment, based on the above method, when the first cylinder 2 moves relative to the second cylinder 3, the minimum distance between the bottoms of the first cylinder 2 and the second cylinder 3 is a, where a≤5mm.

[0040] Furthermore, by making the minimum distance between the bottoms of the first cylinder 2 and the second cylinder 3 less than or equal to 5mm, the cooling medium inside the first cylinder 2 can be brought closer to the puncture site during the initial stage of ice application, thus ensuring the effectiveness of ice application in the initial stage.

[0041] As a preferred embodiment, based on the above method, the switch 8 is further provided with a blocking part 11. The switch 8 is rotatably connected to the second cylinder 3. By rotating the switch 8 relative to the second cylinder 3, the area of ​​the vent 7 blocked by the blocking part 11 is adjusted, thereby controlling the size of the vent 7.

[0042] Furthermore, by rotating the switch 8 relative to the second cylinder 3, the area blocked by the blocked part 11 on the vent 7 is controlled, thereby improving the convenience of adjusting the size of the vent 7.

[0043] As a preferred embodiment, based on the above method, the blocking part 11 can completely block the vent 7, thereby sealing the vent 7.

[0044] Furthermore, the shielding part 11 can completely block the air vent 7, thereby maintaining the gas volume in the first chamber 5 and fixing the relative position of the first cylinder 2 and the second cylinder 3. This ensures that the distance between the first cylinder 2 and the puncture site remains constant, thus maintaining a relatively constant ice-packing effect of the cooling medium on the puncture site. This further improves the diversity of ice-packing methods of the post-coronary angiography ice-packing device of this application.

[0045] As a preferred embodiment, based on the above method, the reset spring 10 is further located in the first chamber 5, one end of the reset spring 10 is connected to the first baffle 4, and the other end is connected to the second cylinder 3.

[0046] Furthermore, by connecting one end of the return spring 10 to the first baffle 4 and the other end to the second cylinder 3, the return spring 10 can drive the first cylinder 2 to move relative to the second cylinder 3 by its own elastic force.

[0047] As a preferred embodiment, based on the above method, the first cylinder 2 is further provided with a liquid injection port 12, through which the cooling medium can be injected into the first cylinder 2, and the liquid injection port 12 is adapted to a cover 13.

[0048] Furthermore, by providing the injection port 12, the convenience of injecting cooling medium into the cylinder is further improved. Ice or water can be injected into the first cylinder 2 through the injection port 12. At the same time, a cover 13 is provided to facilitate sealing the first cylinder 2 after the cooling medium is injected.

[0049] Example 2: Based on the technical solution of Example 1, further details are provided below. Figure 1 and Figure 3 As shown, the bottom of the second cylinder 3 is provided with a number of air holes 9, making the bottom of the second cylinder 3 hollow.

[0050] Furthermore, by making the bottom of the second cylinder 3 hollow, the air permeability of the bottom of the second cylinder 3 is further improved.

[0051] As a preferred embodiment, based on the above method, the post-coronary angiography ice pack device further includes a restraint strap 14 and a base 15. The ice pack component 1 is disposed on the base 15, and the restraint strap 14 is used to restrain the base 15 to the patient's limb so that the ice pack component 1 applies pressure to the patient's puncture site.

[0052] Furthermore, by setting the restraint strap 14 and the base 15, it is easy to restrain the base 15 and the ice pack component 1 to the patient's limb, thereby facilitating the application of pressure to the puncture site by the ice pack component 1. Specifically, the second cylinder 3 on the ice pack component 1 applies pressure to the puncture site, thereby exerting pressure on the puncture site. The restraint strap 14 can be a detachable Velcro strap. The specific structure of the restraint strap 14 is existing technology and will not be described in detail here.

[0053] In a preferred embodiment, based on the above method, the second cylinder 3 is rotatably connected to the base 15. By rotating the second cylinder 3 relative to the base 15, the second cylinder 3 moves relative to the base 15 along its own length direction, thereby adjusting the pressure applied by the bottom of the second cylinder 3 to the patient's puncture site.

[0054] Furthermore, by rotatably connecting the second cylinder 3 to the base 15, when the second cylinder 3 rotates relative to the base 15, it is possible for the second cylinder 3 to rotate relative to the base 15 along its own length direction, thereby facilitating the adjustment of the pressure applied by the bottom of the second cylinder 3 to the patient's puncture site, thus improving the convenience of applying pressure to the puncture site.

[0055] In this application, the bottom of the first cylinder 2 is thinner so that the cooling medium inside the first cylinder 2 can be conducted through the bottom of the first cylinder 2 to the puncture site and the dressing on the puncture site.

[0056] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
