Description

Technical Field

[0001] The invention relates to the technical field of battlefield first aid hemostasis equipment, in particular to a battlefield first aid hemostasis device used for limbs. Background Art

[0002] Massive bleeding is one of the main causes of death for battlefield casualties. Therefore, hemostasis technology is the key technology of the "Platinum Ten Minutes" on-site first aid for domestic and foreign military forces, and is of key significance for reducing the death rate and improving the survival rate of the wounded. A series of first-line treatment equipment for vascular injuries and combat trauma has been introduced and successfully applied on the modern battlefield, playing an important role in reducing the amputation rate and mortality rate on the battlefield and improving the ability to treat combat trauma.

[0003] The most important means of effectively stopping bleeding for wounded soldiers with vascular injuries in war trauma is to use a tourniquet. At present, the traditional tourniquet is mainly a rotary tourniquet. Improper use can also cause complications such as local pain, neuromuscular injury, ischemia-reperfusion injury, and venous thrombosis. In particular, when the tourniquet pressure is insufficient, venous return will be blocked without compressing the artery, thereby aggravating bleeding. Therefore, it is urgent to design a battlefield emergency hemostasis device to improve the battlefield survival rate of the wounded and reduce complications such as limb ischemia and necrosis caused by the use of traditional tourniquets. Summary of the invention

[0004] In response to the above technical problems, the present invention provides a battlefield emergency hemostasis device, which can stop bleeding on the wound by inflating and pressurizing the airbag. The overall width of the airbag can be adjusted to accommodate wounds of different sizes, and the airbag inflation and hemostasis time can be controlled in a timely manner. It not only meets more usage needs, but also reduces the problem of limb necrosis caused by long pressurized hemostasis time.

[0005] To achieve the above object, the technical solution of the present invention is as follows:

[0006] A battlefield first aid hemostatic device, characterized in that it comprises a fixing part, a pressurized hemostatic component, a dressing component and a control panel, wherein the control panel is mounted on the outside of the fixing part and is located at the center, the inside of the fixing part is equipped with a pressurized hemostatic component, and the inner side of the pressurized hemostatic component is equipped with a dressing component.

[0007] The pressurized hemostasis assembly consists of an airbag, an air pump, an air delivery pipe, a connecting pipe, an electric control valve and a pressure sensor. Three groups of the airbags are arranged at intervals on the inner side of the fixed part. Adjacent airbags are connected through connecting pipes. The connecting pipe is equipped with an electric control valve. The air inlet of one of the airbags is connected to the air outlet of the air pump through an air delivery pipe. A pressure sensor is arranged in the air delivery pipe. The air pump is installed in a control panel.

[0008] Furthermore, an air intake pipe is provided at the air intake end of the air pump, the front end of the air intake pipe extends from the control panel and a filter is provided at the front end of the air intake pipe to filter the incoming gas to prevent impurities in the air from entering the airbag.

[0009] The dressing assembly consists of a bandage, hemostatic powder and an adhesive film. The bandage is connected to the inner side of the airbag, and the hemostatic powder and the adhesive film are arranged on the bandage in sequence.

[0010] A mounting cover is provided at the lower side of the bandage, and a chip-type humidity sensor is installed in the mounting cover. The chip-type humidity sensor is arranged in contact with the bandage, and is installed in the mounting cover to protect the chip-type humidity sensor through the mounting cover to prevent the sensor from being squeezed and damaged by the airbag pressurizing the hemostasis.

[0011] Furthermore, the hemostatic powder is a medicine powder containing chitosan components, and is used to quickly stop bleeding from wounds.

[0012] Furthermore, a protrusion is provided on one end of the attachment film, so that the user can quickly tear off the attachment film through the protrusion.

[0013] The control panel is composed of a housing, a rear cover, a display screen, a circuit board, a gear key, a timing key and a display light. The housing is provided with a rear cover, a circuit board is fixedly installed inside the housing, a main control chip is provided on the circuit board, and the housing is provided with a display screen, a gear key, a timing key and a display light.

[0014] Furthermore, the display light consists of a red light and a green light. When the red light is on, it means that bleeding is detected at the wound, and when the green light is on, it means that there is no bleeding at the wound.

[0015] The control chip is electrically connected to the air pump, the electric control valve, the pressure sensor, the chip-type humidity sensor, the display screen, the gear key, the timing key and the display light respectively to control the operation of the electronic components.

[0016] Specifically, the airbag is made of transparent plastic material.

[0017] Specifically, the fixing part is made of a soft ruler material to fix the device on the bleeding site.

[0018] The hemostatic device designed by the present invention can be clamped on the bleeding site at the limbs and other positions through the fixing part, and the attached film on the bandage is torn off and taken out, so that the hemostatic powder on the bandage contacts the wound to stop bleeding, and the width of the airbag is adjusted by the gear key on the control panel according to the size of the bleeding hole. When the bleeding hole can be pressurized and hemostatic, the electric control valve on the connecting pipe connecting the airbag and the other two groups of airbags is in a closed state; when the wound is too large and the number of airbags needs to be adjusted, the gear key is used to control the electric control valve to be in an open state, so as to complete the adjustment of the overall width of the airbag and meet more usage requirements;

[0019] The pressure sensor designed in the present invention can be used to detect the air pressure in the airbag to avoid excessive pressure causing aggravation of wound pain, and the inflation hemostasis time can be controlled by the timing key set on the control panel to achieve control of the pressurized inflation hemostasis time to avoid complications or limb necrosis caused by too long a time.

[0020] The present invention provides a chip-type humidity sensor on the lower side of the bandage in the dressing assembly. The chip-type humidity sensor monitors the humidity of the bandage to determine whether the bleeding site is bleeding. After the detection situation is transmitted to the control chip on the circuit board, the control chip controls the corresponding light in the display light to light up, thereby assisting personnel in determining the bleeding situation of the wound, especially at night or in dark environments, to avoid the risk of exposure caused by the need to use lighting equipment to observe the wound location.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] Example 1

[0032] As shown in the figure, the control panel 1 is installed on the outer surface of the fixed part 2 and is located at the center of the fixed part 2. The fixed part 2 is made of a soft ruler. It should be noted that the soft ruler is made of spring steel. The spring steel is usually installed inside the snap ring. Spring steel sheets are the key component to achieve its snap-close function. The principle is that the spring steel sheets have good elasticity and memory, and can quickly return to a curled state after being straightened, thereby tightly encircling the wrist.

[0033] A pressurized hemostasis component is installed on the inner side of the fixed part 2, and the pressurized hemostasis component consists of an airbag 31, an air pump 6, an air supply pipe 32, a connecting pipe 33, an electric control valve 34 and a pressure sensor. The three groups of airbags are arranged at intervals on the inner side of the fixed part 2, and the adjacent airbags 31 are connected by a connecting pipe 33, and an electric control valve 34 is installed on the connecting pipe 33. The electric control valve 34 controls the connectivity of the three groups of airbags 31, thereby adjusting the number of inflation airbags 31, thereby adjusting the pressurized width. In addition, the airbag 31 used in the present application is made of transparent plastic material.

[0034] The air inlet of the outermost airbag 31 among the three groups of airbags 31 is connected to the air outlet end of the air pump 6 through an air pipe 32, and a pressure sensor is provided in the air pipe 32 to monitor the pressure in the airbag. The air pump 6 is installed in the housing 11 of the control panel 1.

[0035] like Figure 6 Furthermore, an air intake pipe 61 is provided at the air intake end of the air pump 6, and a front end of the air intake pipe 61 extends out from the control panel 1 and a filter screen 7 is provided at the front end of the air intake pipe 61, through which the filter screen 7 is used to filter the incoming gas to prevent impurities in the air from entering the airbag 31.

[0036] like Figure 1 and 4 As shown, a dressing assembly is provided on the inner side of the three groups of airbags 31, and the dressing assembly is composed of a bandage 41, hemostatic powder and an attachment film 42. The bandage 41 is connected to the inner side of the airbag 31, and the bandage 41 is provided with hemostatic powder and an attachment film 42 in sequence. The attachment film 42 is to prevent the hemostatic powder on the surface of the bandage 41 from being directly exposed to the outside and contaminated by bacteria. The disposable attachment film 42 is provided on the inner side of the bandage 41 to protect the inner surface of the bandage 41 and the hemostatic powder from being contaminated by bacteria. Among them, the hemostatic powder can be a powder containing chitosan components, which is used to quickly stop bleeding from wounds.

[0037] In addition, a mounting cover 43 is provided on the lower side of the bandage 41. A chip-type humidity sensor is installed in the mounting cover 43, and the chip-type humidity sensor is arranged in contact with the bandage 41. The sensor is installed in the mounting cover 43 to protect the chip-type humidity sensor through the mounting cover 43, so as to prevent the airbag 31 from squeezing and damaging the sensor when applying pressure to stop bleeding. It should be noted that the chip-type humidity sensor used is an existing device, so its specific structure will not be described or shown in detail in this application.

[0038] Furthermore, a protrusion 421 is provided at a corner of the attachment film 42 , so that the user can quickly tear off the attachment film 42 through the protrusion 421 .

[0039] like Figure 5and 6 A rear cover 12 is provided at the mounting slot of the shell 11 of the control panel, and a circuit board 5 is fixedly installed in the mounting slot of the shell 11. A main control chip 51 is provided on the circuit board 5, and a display screen 52, a gear key 54, a timing key 54, a red light 551 and a green light 552 are provided on the front side of the shell 11. The red lights 551 and 552 are used to display the bleeding situation of the wound. When the red light 551 is on, it means that bleeding from the wound is detected, and when the green light 552 is on, it means that there is no bleeding at the wound.

[0040] like Figure 6 As shown, the control chip 51 is electrically connected to the air pump 6, the electric control valve 34, the pressure sensor, the chip-type humidity sensor, the display screen 52, the gear key 54, the timing key 53, and the red light 551 and the green light 552, respectively, and the operation of these electronic components is controlled by the control chip 51.

[0041] Example 2

[0042] When using the present invention, the fixing part 2 is bent and formed arbitrarily, and then the device is clamped on the bleeding part at the limbs and the like. Before clamping on the bleeding part, the attachment film 42 on the bandage 41 should be torn off and removed, so that the hemostatic powder on the bandage 41 contacts the wound to stop bleeding, and the width of the airbag can be adjusted by the gear key 54 on the control panel 1 according to the size of the bleeding hole.

[0043] When one airbag 31 is used to apply pressure to stop bleeding, the electric control valve 34 on the connecting pipe 32 connecting the airbag and the other two groups of airbags is in a closed state; when the wound is too large and the number of airbags needs to be adjusted, the corresponding gear key 54 is selected and pressed to transmit a signal to the control chip 51, and the control chip 51 controls the electric control valve 34 to open, so that multiple airbags 31 are inflated, thereby adjusting the overall width of the pressurization to meet more usage requirements;

[0044] In addition, a pressure sensor is added to the air supply pipe 32 for supplying air to the airbag 31 to detect the air pressure in the airbag 31 to avoid excessive pressure causing aggravation of wound pain, and the inflation hemostasis time can be operated by the timing key 53 set on the control panel 1. The timing operation is performed by the timing key 52, and the signal is transmitted to the control chip 51, which controls the pressurized inflation hemostasis time. When the time is up, the inflation pump 6 is controlled to stop working to avoid complications or limb necrosis caused by too long a time.

[0045] A chip-type humidity sensor is provided on the lower side of the bandage 41 in the dressing assembly. The humidity of the bandage is monitored by the chip-type humidity sensor to determine whether the bleeding site is bleeding. After the detection situation is transmitted to the control chip 51 on the circuit board 5, the control chip 51 controls whether the display light is red light 551 or green light 552, so as to assist personnel in judging the bleeding situation of the wound, especially at night or in dark environments, to avoid the risk of exposure caused by the need to use lighting equipment to observe the wound location.
