Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a multi-chamber inflatable compression hemostat. Background Art

[0002] In recent years, with the continuous development of diagnosis and treatment technology, more and more pacemakers are implanted. When the pacemaker pocket is used to stop bleeding, complications such as bleeding at the wound, pocket hematoma, and pocket infection often occur. Many studies have shown that different compressors, compression methods, and compression time have a significant impact on the hemostatic effect and the occurrence of complications.

[0003] At present, pouch hemostasis mainly relies on conventional bandage pressure dressing and visual inspection. However, these methods have many shortcomings, such as the inability to achieve effective compression hemostasis and difficulty in real-time monitoring of wound conditions. Some airbag designs in the prior art have certain limitations in compression effects, and fail to achieve sufficient and effective compression of the pouch, resulting in problems such as postoperative bleeding and infection that are difficult to completely resolve. Moreover, there are deficiencies in pressure monitoring, and it is impossible to provide visual information. It is difficult for medical staff to observe the pressure status of the bandage in real time, and thus it is impossible to understand whether the pouch hemostasis is up to standard. If the pressure is too high, it may cause ischemia and necrosis of the wound and pouch tissue and skin, leading to serious complications.

[0004] After searching, the patent number is CN202320773477.8, and the patent name is a Chinese patent for an inflatable radial artery compression hemostat, which mainly includes: a fixing belt; an air bag, which is composed of a main air bag and type I and II auxiliary air bags; three air injection holes connected to the main air bag and type I and II auxiliary air bags; ventilation tubes I and II are connected to type I auxiliary air bags and type II auxiliary air bags respectively. The above-mentioned prior art alternately inflates and deflates two types of auxiliary air bags at the same time, but the size of the required compression area cannot be adjusted according to the wound area, and the pressure cannot be monitored.

[0005] The patent number is CN201820066949.5, and the patent name is a Chinese patent for an inflatable arterial compression hemostat, which includes an upper plate buckle, a lower plate buckle, a main airbag and an auxiliary airbag. The upper plate buckle is provided with an airbag box, and the main airbag and the auxiliary airbag are located in the airbag box. The lower end of the airbag box is provided with symmetrically distributed adjustment plates, and the lower end of the airbag box is provided with slideways at the corresponding positions of the two sides of the adjustment plate. The two sides of the airbag box are provided with openings at the corresponding positions of the slideways, and the adjustment plate slides in the slideway through the openings. The above-mentioned prior art can limit the size of the compression area of ​​the main airbag through two adjustment plates, but it is impossible to monitor the pressure in real time.

[0006] Therefore, it is extremely important to design a multi-chamber inflatable compression hemostat. Utility Model Content

[0007] The utility model aims to overcome the above-mentioned shortcomings of the prior art and provides a multi-chamber inflatable compression hemostat.

[0008] The hemostat is designed to adjust the wound compression area by arranging multiple air chambers in a multi-chamber compression device. At the same time, it is also necessary to monitor the pressure in the air chamber and be able to indicate that the pressure has reached a predetermined value.

[0009] Based on the above technical ideas, the technical solution adopted by the utility model is:

[0010] A multi-chamber inflatable compression hemostat, comprising: a fixing belt and an inflating device, and also comprising:

[0011] A multi-chamber compression device, which is arranged on the fixing belt and connected to the inflation device. The multi-chamber compression device is used to perform multi-layer compression on the wound to stop bleeding, and the size of the compression area can be adjusted;

[0012] A pressure monitoring device is provided on the multi-chamber compression device, and is used to monitor the pressure in the multi-chamber compression device and to serve as a warning.

[0013] In the above technical solution, preferably, the multi-chamber compression device includes a plurality of air chambers, the plurality of air chambers have the same shape and are arranged in sequence, the plurality of air chambers are not connected and are independently connected to the inflation device.

[0014] As a further limitation of the above technical solution, the plurality of air chambers are all annular and increase in size from the inside to the outside.

[0015] In the above technical solution, it is further defined that the plurality of air chambers are all made of transparent material.

[0016] In the above technical solution, further, the pressure monitoring device is pressure-sensitive paper, and pressure-sensitive paper is arranged in each of the plurality of air chambers.

[0017] Beneficial effects of the utility model:

[0018] First: The utility model provides a multi-chamber compression device, which includes multiple air chambers. The multiple air chambers have the same shape but different sizes and are arranged in sequence. The multiple air chambers can be inflated independently, and the compression area can be adjusted according to the patient's wound condition. When the patient's wound area is small, only the innermost air chamber can be inflated. When the patient's wound area is large or there is hematoma, the outer air chamber can be inflated to increase the compression area of ​​the wound. The required compression area can be adjusted according to the patient's wound condition.

[0019] Second: The utility model sets pressure-sensitive paper in multiple air chambers and inflates each of the multiple air chambers independently. When the pressure value is reached, the pressure-sensitive paper in the air chamber will change color, and inflation can be stopped at this time to ensure that the pressure on the wound is sufficient and effective. When a certain air chamber is damaged, the temperature changes, shifts, etc., causing the pressure of the multi-chamber compression device to drop below the specified pressure value, the pressure-sensitive paper will change back to its original color, thereby issuing a warning and achieving the purpose of real-time pressure adjustment.

[0020] Third: The air chambers are all transparent, and the air chambers located at the patient's wound are relatively flat areas.

[0021] Therefore, the compression and hemostasis of the wound can be observed here, and whether there is bleeding or swelling can be observed, so as to achieve the purpose of wound status monitoring. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Please refer to the following Figure 1-5 , the complete technical scheme and embodiments of this application are explained in detail. Example

[0032] This embodiment provides a multi-chamber inflatable compression hemostat, such as Figure 1-3 As shown, it includes: a fixing belt and an inflation device, and also includes: a multi-chamber compression device 2, which is arranged on the fixing belt and connected to the inflation device. The multi-chamber compression device 2 is used to perform multi-layer compression hemostasis on the wound, and the size of the compression area can be adjusted. A pressure monitoring device, the pressure monitoring device is arranged on the multi-chamber compression device 2, and the pressure monitoring device is used to monitor the pressure in the multi-chamber compression device 2 and serve as a warning.

[0033] The fixing belt in this embodiment includes a chest belt and a shoulder belt 102, wherein the chest belt includes a first chest belt 1 and a second chest belt 101, wherein the first chest belt 1 and the second chest belt 101 are detachably connected and the length is adjustable, and the other ends thereof are connected to the relative outer surface of the outermost air chamber 201, and the shoulder belt 102 is detachably connected to the chest belt and the length is adjustable, and the other ends thereof are connected to the outer surface of the outermost air chamber 201.

[0034] In this embodiment, the first chest strap 1 and the second chest strap 101 are detachably connected and have their lengths adjusted by Velcro. This is not limited to Velcro, but can also be set to a Japanese buckle or multiple buttons to achieve detachable connection and length adjustment. Similarly, the shoulder strap 102 can be detachably connected to the chest strap. The fixing strap here is designed based on the example of wound compression and hemostasis after pacemaker puncture surgery. The pacemaker implantation puncture wound is located on the anterior chest wall below the clavicle. When wearing it, the first chest strap 1 and the second chest strap 101 need to be passed through the patient's armpits and around the patient's back. The position of the multi-chamber compression device 2 is adjusted so that the multi-chamber compression device 2 is located at the patient's wound. According to the patient's chest size, it is adjusted to a suitable length, the first chest strap 1 and the second chest strap 101 are connected by Velcro, and then the shoulder strap 102 is passed around the patient's shoulders to the patient's back. The length is adjusted and the shoulder strap 102 is connected to the chest strap. A flexible protective pad can also be sleeved outside the chest strap and the shoulder strap 102 to make the patient more comfortable to wear.

[0035] The multi-chamber compression device 2 comprises a plurality of air chambers 201, which are of the same shape and are arranged in sequence, are annular and increase in size from the inside to the outside, and are not connected and are independently connected to the inflation device.

[0036] The multi-chamber compression device 2 in this embodiment includes three air chambers 201, which are triangular ring-shaped, and the three air chambers 201 have the same shape but different sizes. The three air chambers 201 are arranged in sequence, and the size of the air chambers 201 increases from the inner circle to the outer circle. The multiple air chambers 201 can be inflated independently, and the compression area can be adjusted according to the patient's wound status. When the patient's wound area is small, only the innermost air chamber 201 can be inflated. When the patient's wound area is large or there is hematoma, the outer air chamber 201 can be inflated to increase the compression area of ​​the wound, and the required compression area size can be adjusted according to the patient's wound status. The air chamber 201 can also be not limited to being set to three, but can also be set to two, four or more, which can be adjusted in real time according to the actual clinical situation. The multi-chamber compression device 2 is made of flexible material, preferably medical-grade polyurethane material, to ensure that it is friendly to the patient's skin.

[0037] The air chamber 201 is arranged in a ring shape. When the required compression area increases and the outer ring air chamber 201 needs to be inflated, the compression of the wound by the air chamber 201 can be extended in a corrugated shape, so that the compression of the wound by the air chamber 201 is more uniform and effective; and because a pressure-sensitive paper 203 needs to be arranged in each air chamber 201, when the predetermined pressure value is reached, the pressure-sensitive paper 203 will change color, and medical staff or family members also need to observe whether the patient's wound has bleeding or swelling through the wound area of ​​the multi-chamber compression device 2. At this time, it is only necessary to observe from the hollow part of the air chamber 201, and the color change of the pressure-sensitive paper 203 will not interfere with the observation of the wound.

[0038] The inflation device in this embodiment includes a gas pressure source, one end of which is connected to an inflation tube 301, the inflation tube 301 is connected to a valve 302, the other end of the valve 302 is connected to multiple ventilation tubes 303, the multiple ventilation tubes 303 are respectively connected to the multiple ventilation holes 202 on the air chamber 201, and a two-way valve 304 is arranged between the ventilation hole 202 and the ventilation tube 303.

[0039] The gas pressure source in this embodiment is an inflatable handball bag 3, and a micro-electric air pump or a compressed air source can also be used as the gas pressure source. The valve 302 is set to transport the gas to each air chamber 201. Three air chambers 201 are set in this embodiment, so the valve 302 here is a four-way valve, and three ventilation pipes 303 are connected to the other end of the four-way valve. The three ventilation pipes 303 are respectively connected to the ventilation holes 202 of the three air chambers 201 to realize independent inflation of the three air chambers 201. The two-way valve 304 is set so that when the pressure in the air chamber 201 reaches a predetermined value, the two-way valve 304 of the air chamber 201 can be closed to stop inflation of the air chamber 201, and the ventilation pipe 303 can be removed from the two-way valve 304.

[0040] The plurality of air chambers 201 are transparent and the area for compressing the wound is relatively flat, so that it is convenient to inspect the wound after pacemaker surgery through this area, observe the compression and hemostasis of the wound, and whether there is bleeding or swelling, so as to achieve the purpose of monitoring the wound status.

[0041] The pressure monitoring device is a pressure-sensitive paper 203 , and each of the plurality of air chambers 201 is provided with a pressure-sensitive paper 203 .

[0042] Pressure sensitive paper 203 is a special type of paper that has a pressure sensitive coating (also called a pressure sensitive film) on its surface. This coating reacts to applied pressure, usually by changing color to indicate the presence of pressure. This color change is due to the specific chemicals contained in the pressure sensitive coating changing when subjected to a certain amount of pressure, resulting in a change in the wavelength of visible light, thus showing a different color.

[0043] Each inflatable chamber 201 is provided with a piece of pressure-sensitive paper 203. When the pressure in the air chamber 201 reaches the specified value, the color of the pressure-sensitive paper 203 will change, indicating that the pressure in the air chamber 201 has reached the standard. At this time, the inflation can be stopped to ensure that the pressure on the wound is sufficient and effective when worn. The air chamber 201 is set to be transparent, which is also convenient for timely observation of the color change of the pressure-sensitive paper 203. When a certain air chamber 201 is damaged, temperature changes, shifted, etc., causing the pressure of the multi-chamber compression device 2 to drop below the specified pressure value, the pressure-sensitive paper 203 will change back to its original color, thereby issuing a warning and achieving the purpose of real-time pressure adjustment.

[0044] The multi-chamber inflatable compression hemostat of the utility model can also be used for hemostasis of the femoral artery, radial artery, brachial artery, etc. The basic structure and principle of the multi-chamber compression device 2 are the same. It is only necessary to provide multi-chamber compression devices 2 of different sizes and specifications according to different parts. At the same time, it is also necessary to provide fixing belts of different sizes and specifications according to the wearing part of the hemostat. Example

[0045] This embodiment is an improvement on the basis of embodiment 1. Figure 4-5 As shown, the difference in design is that the shape of the air chamber 201 is semicircular, which has the same structural design principle as the air chamber 201 in Example 1, but with a different shape. A pressure-sensitive paper 203 is provided in each air chamber 201 for pressure monitoring. In order to facilitate observation of the wound and fully and effectively compress the wound, the straight segment area in the semicircular air chamber 201, that is, the flat area, is the area for compressing the patient's wound.

[0046] Similarly, the air chamber 201 of the present invention is not limited to the shapes in the above two embodiments, and can also be set to a polygonal ring shape, as long as the pressure-sensitive paper 203 is set in each of the multiple air chambers 201 and the area for compressing the wound is relatively flat.

[0047] Patient Huang, an 84-year-old male, underwent permanent pacemaker implantation for sinus bradycardia. After the pacemaker wound was sutured, he wore this device to compress and stop bleeding.

[0048] When wearing it, the first chest strap 1 and the second chest strap 101 need to be passed through the patient's armpits and around the patient's back, and the position of the multi-chamber compression device 2 is adjusted so that the multi-chamber compression device 2 is located at the patient's wound. According to the patient's chest size, it is adjusted to an appropriate length, and the first chest strap 1 and the second chest strap 101 are connected by Velcro. Then, the shoulder strap 102 is passed around the patient's shoulders to the patient's back, and the length is adjusted. The shoulder strap 102 and the chest strap are connected to fix the fixing belt and the multi-chamber compression device 2.

[0049] Connect the inflation tube 301 with the two-way valve 304, open the two-way valve 304 of the air chamber 201 to be inflated, squeeze the inflatable handball bag 3 to expand the air chamber 201, observe the color of the pressure-sensitive paper 203 in the air chamber 201, and when the color changes, the predetermined pressure value is reached, and there is no bleeding or exudation from the wound. At this time, stop inflating, close the two-way valve 304, and then remove the ventilation tube 303, valve 302, inflation tube 301 and inflatable handball bag 32 from the two-way valve 304, so that the air chamber 201 always keeps compressing the wound. During the compression process, medical staff or the patient's family members also need to observe the patient's wound compression hemostasis in real time, observe whether there is bleeding or swelling, and monitor the wound status. The compression time is 24 hours. After 6 hours of compression without bleeding or exudation of the wound, the compression pressure of the 201 air chamber can be reduced.

[0050] Then, the compression area can be adjusted according to the patient's wound status. When the patient's wound area is small, only the innermost air chamber 201 can be inflated. When the patient's wound area is large or there is hematoma, the outer air chamber 201 can be inflated to increase the compression area of ​​the wound. The required compression area size is adjusted according to the patient's wound status. Taking the compression hemostasis of the puncture wound after pacemaker surgery as an example, the required compression area is approximately a circle with a diameter of 10 cm, and when hematoma occurs, the required compression area will increase. When it is necessary to stop the compression, just open the two-way valve 304 at the vent 202 of the air chamber 201, and let the air in the air chamber 201 out to stop the compression of the wound.

[0051] It should be clear that the above detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
