Description

Technical Field

[0001] The present invention relates to the technical field of first aid equipment, and more particularly to a single-person self-rescue device. Background Art

[0002] When faced with life-threatening situations such as severe bleeding, the ability to take effective self-rescue measures during the "golden rescue window" before professional rescuers arrive directly affects the victim's chance of survival. Single-person self-rescue equipment, as a tool that can be operated independently by an individual in an emergency and provides survival protection, enables individuals to take immediate self-rescue action. While awaiting external assistance, they can create a relatively safe living environment, maintain vital signs, and buy themselves more time to survive.

[0003] In the event of blood loss caused by trauma, if the injured person does not have effective single-person self-rescue equipment to manage the bleeding, not only will their physical functions decline due to the blood loss, making self-rescue more difficult, but prolonged blood loss may also lead to serious consequences such as shock, endangering their lives. At the same time, when the injured person has lost a large amount of blood, timely blood replenishment is also crucial to saving lives. At the scene of injury and bleeding, when professional rescue personnel and blood transfusion resources are not available in time, a single-person self-rescue device with blood collection and transfusion functions allows the injured person or on-site personnel to quickly initiate self-rescue. This device can reduce the injured person's dependence on external blood bank resources and professional blood transfusion equipment. In an emergency, there is no need to wait for a blood supply with a matching blood type, and the use of one's own blood for transfusion not only solves the problem of blood source but also reduces the risk of transfusion reactions caused by blood type mismatch.

[0004] Therefore, developing a single-person self-rescue device that can achieve timely hemostasis, blood collection and blood transfusion, so that the injured can independently complete blood transfusion while waiting for professional rescue, is of great significance for improving the survival rate of the injured and filling the gap in emergency rescue.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0028] Example:

[0029] This embodiment provides a single-person self-rescue device that can stop bleeding in time and can collect and transfuse blood, so that the injured person can independently complete blood transfusion while waiting for professional rescue. At the same time, the single-person self-rescue device can also supplement and transfuse pre-prepared autologous blood back into the injured person's body, which can greatly improve the injured person's chance of survival in an emergency.

[0030] For details, see Figures 1-4 The single-person self-rescue device includes at least one device shell 1, inside of which are installed a blood pump 2, a built-in blood tank 3 and a control chip 4. A silicone blood-sucking ring 5 containing a hemostatic agent is installed on the bottom edge of the device shell 1. The inner circle area of ​​the silicone blood-sucking ring 5 is connected to the inlet blood vessel of the blood pump 2, and the outlet blood vessel of the blood pump 2 is connected to the inlet of the built-in blood tank 3.

[0031] During use, the injured person aims the silicone blood-sucking ring 5 at the wound and presses it. The silicone blood-sucking ring 5 can block the blood flowing out of the wound, and then the blood pump 2 will first collect the blood into the built-in blood tank 3 to prevent it from being lost and wasted. At the same time, the silicone blood-sucking ring 5 also contains a hemostatic agent, which can quickly activate coagulation factors after contacting blood, forming a gel-like hemostatic layer, thereby achieving the effect of quickly stopping bleeding from the wound.

[0032] Also matched with the device housing 1 are a blood monitor body 6, a power supply battery 7, an external blood tank 8, and an autologous blood tank 9. The blood monitor body 6 and the power supply battery 7 are installed in the device housing 1, and the power supply battery 7 is electrically connected to the blood monitor body 6, the blood pump 2, and the control chip 4 respectively. The blood monitor probe is inserted into the blood pump 2 to measure the bleeding rate and bleeding pressure of the wound; the control chip 4 is integrated with a position module, a wireless communication module, etc. The control chip 4 is communicated with a remote monitoring device (such as a smart phone or a computer), and the remote monitoring device monitors and obtains the injured person's blood parameters, location information and distress signals.

[0033] The external blood tank 8 and the autologous blood tank 9 are placed as a whole in a waist-mounted container 10 outside the device housing 1 to facilitate the user to carry; the inside of the device housing 1 is also provided with an external guiding channel 11 and a blood return channel 12, one end of the external guiding channel 11 is connected to the outlet of the internal blood tank 3, and the other end of the external guiding channel 11 is connected to the inlet of the external blood tank 8 in the waist-mounted container 10 through a flexible telescopic channel tube 14, the outlet of the external blood tank 8 is connected to the inlet of the autologous blood tank 9, and the outlet of the autologous blood tank 9 is connected to the blood return channel 12 inside the device housing 1 through a corresponding flexible telescopic channel tube 14, and the port of the blood return channel 12 extending outside the device housing 1 can be connected to a preset return needle 13 through a corresponding flexible telescopic channel tube 14.

[0034] In actual situations, a sterilization and filtration component can be set up during the blood transfusion process to sterilize and filter the returned blood, thereby improving the safety of the injured during blood transfusion.

[0035] Alternatively, to further save costs, in this embodiment, the blood pump and the blood sterilization and filtration component can be integrated into one structure. This structure is called CATS (also called autologous blood transfusion machine) in the prior art, but the CATS in this embodiment should be a miniature version under the certification background of the existing CATS.

[0036] During use, the injured person can insert the preset reinfusion needle 13 into the corresponding arterial site for blood reinfusion; alternatively, the preset reinfusion needle 13 can be pre-buried in the body of the device carrier in advance. During use, the injured person can directly connect the corresponding flexible telescopic channel tube 14 to the preset reinfusion needle 13, which reduces the difficulty of operation.

[0037] In practical embodiments, multiple device housings 1 containing the blood monitor body 6 and power supply battery 7 may be provided, while only one waist-mounted container 10 containing the external blood canister 8 and autologous blood canister 9 is typically provided. In other words, the patient can carry multiple device housings 1 with corresponding internal structures, allowing them to select the device housing 1 closest to the corresponding pre-placed reinfusion needle 13 and connect it to the pre-placed reinfusion needle 13, thereby achieving rapid connection of the blood reinfusion channel 12.

[0038] It should also be noted that the diameter and length of the corresponding flexible telescopic channel tube in this embodiment need to be matched with the corresponding equipment to ensure that the amount of blood flowing through it does not exceed the maximum limit and return rate that the human body can withstand.

[0039] In a further specific embodiment, the device housing 1 can be designed to have a shape similar to that of a three-dimensional mouse housing, and a mouse control circuit board can also be installed inside the device housing 1. A mouse control switch and several mouse control keys are correspondingly set on the outer wall of the device housing 1.

[0040] In other words, the single-person self-rescue device in this embodiment can also be designed to have the function of a mouse to further expand the usage scenarios of the single-person self-rescue device.

[0041] In a further specific embodiment, the device housing 1 is made of medical-grade transparent adhesive material, which allows the user to clearly see the working status of each mechanism in the device housing 1, especially the blood status in the built-in blood tank 3.

[0042] In this embodiment, the internal blood tank 3 is a 250cc blood tank, the external blood tank 8 is an initially empty 400cc blood tank, and the autologous blood tank 9 is a blood tank that initially stores 400cc of autologous blood. Furthermore, the internal blood tank 3, the external blood tank 8, and the autologous blood tank 9 are all graduated, flexible medical bags or flat bottles, minimizing the overall size of the device.

[0043] At the same time, the autologous blood tank 9 can be designed accordingly (such as an autologous blood tank that can be refrigerated at low temperatures) to ensure that the autologous blood pre-stored therein will not deteriorate.

[0044] In a further specific embodiment, the blood pump used in this embodiment is a magnetic levitation blood pump, and the impeller is placed in the blood pump through a magnetic levitation bearing. The impeller is in a suspended state and rotates at high speed while completely out of contact with the pump casing.

[0045] The magnetic levitation blood pump uses magnetic levitation technology to achieve contactless rotation of the impeller. Compared with traditional mechanical bearing blood pumps, the magnetic levitation structure design is more compact, so the blood pump can be made smaller and easier to integrate into the equipment housing.

[0046] In a further specific embodiment, a temperature regulator 15 electrically connected to the power supply battery 7 is also installed in the device housing 1. The temperature control probe in the temperature regulator 15 is used to control and adjust the temperature inside the device housing 1 so that the blood in the blood retransfusion channel 12 can be infused back into the injured person's body at a suitable temperature.

[0047] In this embodiment, the total weight of the blood monitor body 6 , the power supply battery 7 , and the temperature regulator 15 does not exceed 600 grams, so as to minimize the volume of the device.

[0048] In a further specific embodiment, the device housing 1, the blood monitor body 6, the power supply battery 7 and the waist-mounted container 10 can all be coated with stealth radiation-proof coatings.

[0049] Stealth anti-radiation coatings can achieve the dual functions of "reducing the probability of target detection" and "blocking / attenuating harmful radiation". They can enhance the concealment of equipment in military confrontations and ensure the stable operation of equipment and personnel safety in industrial, medical and other fields.
