Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a composite hemostatic device. Background Art

[0002] Hemostatic devices are used in medical institutions for infusion, blood drawing, blood transfusion and hemostasis in routine treatment and rescue, and are also used for emergency hemostasis of limb bleeding. There are many types of devices currently used for hemostasis.

[0003] Commonly used tourniquets require manual operation by medical personnel, and it is difficult to control the binding strength of the tourniquet: if the binding strength is too light, effective bleeding may not be achieved; if the binding strength is too strong, the bleeding can be stopped, but long-term binding may cause tissue damage to the patient's body.

[0004] The Chinese utility model with the authorization announcement number CN205758653U discloses an arterial compression device, such as Figure 1 As shown, the pressing device includes: a wristband; a pressure balloon, which is connected to the air inlet to inflate the airbag; a pressure sensor, which is arranged on the working surface or the front of the airbag; a time relay, which is connected to the pressure sensor, and starts timing when the pressure sensor measures that the inflation pressure in the airbag reaches a preset pressure, and at the same time, the time relay is connected to the solenoid valve, so as to start the internal solenoid valve to discharge the gas in the airbag after the preset time is completed; the internal circuit located on the airbag is connected to the external circuit through a plug connector. Although the device can control pressure and time, since the pressure sensor is arranged on the working surface or the front of the airbag, the pressure felt at the wound site will be different from the value measured by the pressure sensor, and the pressure value and pressing time cannot be adjusted.

[0005] The Chinese invention patent application with publication number CN17547325A discloses an adaptive intelligent hemostasis device. Figure 2 As shown, the hemostatic device includes: a tourniquet, having a distal end and a proximal end, which are respectively the axial ends of the tourniquet, a first tensioning mechanism, arranged at the distal end, and configured to be able to tighten the distal end; a second tensioning mechanism, arranged at the proximal end, and configured to be able to tighten the proximal end; a blood pressure detection device, arranged on the tourniquet and located between the first tensioning mechanism and the second tensioning mechanism, for detecting the patient's blood pressure; and a controller, which is configured to adjust the tightening force of the first tensioning mechanism and the second tensioning mechanism according to the patient's blood pressure. The tensioning mechanism includes an elastic band 5, a winding shaft 6, a motor 7, and a reducer 8. Although the device achieves rapid hemostasis of the tourniquet through the first tensioning mechanism, and after achieving hemostasis with the minimum hemostatic pressure by using the second tensioning mechanism and the blood pressure detection device, the tensioning force of the first tensioning mechanism is reduced to avoid tissue damage caused by excessive hemostatic force. The hemostatic device has a complex structure, and the blood pressure detection device and the tourniquet are an integrated structure.

[0006] The Chinese invention patent application with publication number CN117580525A discloses a monitoring system for a tourniquet, which is used to monitor the hemostasis of a patient in clinical practice, such as Figure 3 , 4 As shown, the monitoring unit 48 includes a housing 100, a controller 102, a data storage unit 104, a charging / communication port 106, a transmitter / receiver 108 configured to communicate with a remote device 110, a communication interface 112 including two LEDs 114, 116 and / or a sound device 115, an input / output display 118, a tension component pressure sensor 66, a pressure component pressure sensor 76, and a power supply 120 for powering the monitoring unit 48. The clinician connects the tension pad 50 to the monitoring unit 48 before fixing the tourniquet 10 on the tension pad. The tourniquet of the invention has a complex structure, and the monitoring unit and the tourniquet interact with each other through a network connection to carry out hemostasis-related information.

[0007] The above-mentioned existing technology can meet the needs of treating the injured when used in daily rescue. However, when a major natural disaster such as an earthquake occurs, a large number of people will be injured in a very short period of time. The injuries of the injured vary, there is a serious shortage of medical staff, and the rescue site may be without power, the Internet, or traffic. It is difficult for other rescue personnel and relief supplies to arrive in time. Under such extreme conditions, how to ensure that the injured can receive as much treatment as possible in the first time and reduce secondary injuries caused by treatment is a problem that needs to be solved.

[0026] In order to make the technical solution of the utility model clearer, the following Figure 5-7 The utility model is described in detail.

[0027] The hemostatic composite device of the utility model comprises a tourniquet 10 and a monitoring device 20 which are separately arranged. The utility model can fix the tourniquet 10 and the monitoring device 20 at the proximal end and the distal end of the injured limb of the injured person respectively by designing the tourniquet 10 and the monitoring device 20 separately, so that the medical staff can operate the two without interfering with each other, thereby avoiding the additional pain that may be caused to the injured person when operating the tourniquet.

[0028] like Figure 5 As shown, the tourniquet 10 of the present invention comprises: an air bag 101 , a pressure balloon 102 , and a first restraining belt 103 .

[0029] The airbag 101 is fixed to the first restraint belt 103 by snaps, buttons, hooks and loops, straps, hook holes, bonding, etc. The airbag 101 has a rigid interface 1011 and an exhaust port 1012 , and the exhaust port 1012 has an adjustable exhaust valve 1013 .

[0030] The pressure balloon 102 includes a balloon body 1021 having an air inlet 1022 with an air inlet check valve, a rigid air outlet 1023 with a pressurized check valve, and a rubber hose 1024. The rigid air outlet 1023 is the same size as the rigid interface 1011 of the air bag 101, and they are connected together through a rubber hose 1024 of a corresponding size. When the medical staff squeezes the pressure balloon 102, the air in the balloon body 1021 is delivered to the air bag 101 through the rigid air outlet 1023 and the rubber hose 1024, while the air is continuously replenished into the balloon body 1021 through the air inlet 1022.

[0031] The first strap 103 is used to fix the tourniquet 10 on the injured limb of the injured person. The first strap 103 consists of three parts. The middle part 1031 fixed to the airbag 101 is not elastic. The two end parts 1032 and 1033 with a certain length are not elastic. One side of one end part 1032 has a furry surface, and the other side of the other end part 1033 has a hook surface. The part between the middle part 1031 and the two end parts 1032 and 1033 is elastic and can be adjusted in tightness. In this way, by adjusting the tightness of the first strap 103 and / or adjusting the bonding range of the furry surface and the hook surface at both ends of the first strap 103, the strap can be applied to different injured persons and different injured limb parts of the injured person.

[0032] When the tourniquet 10 of the present invention is manufactured and not used, the air bag 101, the pressure balloon 102, and the first binding belt 103 are usually connected together, and medical personnel can use it by taking it out of the package, which saves the time of medical personnel.

[0033] In the present invention, the monitoring device 20 is used in conjunction with the tourniquet 10 and is fixed to the distal end of the injured limb of the injured person, such as the wrist or ankle. Figure 6 As shown, the monitoring device 20 is similar in appearance to a watch, and a group of buttons 201 and a display screen 202 are provided on the surface of the shell of the monitoring device 20; the shell is generally rectangular, but can also be circular, elliptical or other shapes, and a pair of connecting mechanisms 208 are symmetrically arranged on both sides of the shell, and the connecting mechanism 208 is used to connect the shell to a second restraint belt (not shown); the shell of the monitoring device 20 is provided with: a pulse sensor 203, a counter 204, an information prompt unit 205, a microprocessor 206, and a battery 207. Figure 7 A principle block diagram of the monitoring device 20 is shown.

[0034] A group of buttons 201 includes a switch button 2011, a time setting button 2012, and a prompt information setting button 2013. The switch button 2011 is used to turn on or off the monitoring device 20. The time setting button 2012 is used for the medical staff to input the pressing time, relaxation time, and the number of pressing-relaxing cycles, and the prompt information setting button 2013 is used for the medical staff to input the prompt information of how to output the pressing time, relaxation time, and the number of pressing-relaxing cycles to reach the preset pressing time, preset relaxation time, and preset number of pressing-relaxing cycles. The button 201 can be a touch type, and different touch modes correspond to different setting contents, so that one touch button can set different contents. For example, the time setting button 2012 uses a touch button, and clicking the touch button once is used for the medical staff to input the time required to be pressed, clicking the touch button twice continuously is used for the medical staff to input the number of pressing-relaxing cycles, and long pressing the touch button once is used for the medical staff to input the relaxation time. Similar settings can also be made for the prompt information setting button 2013.

[0035] The display screen 202 is used to display the content input by the medical staff and the actual elapsed pressing time, relaxation time, and number of pressing-relaxation cycles counted by the counter 204. For example, the pressing time, relaxation time, and number of pressing-relaxation cycles input by the medical staff are displayed in a smaller font at the upper left of the display screen, and the actual elapsed pressing time, relaxation time, and number of pressing-relaxation cycles are displayed in a larger font in the middle of the display screen.

[0036] The pulse sensor 203 is used to sense the pulse information of the injured limb of the injured person and transmit the sensed pulse information to the microprocessor 206. The tourniquet of the utility model does not have a pressure sensor, but a pulse sensor is set in the monitoring device, so that the hemostasis of the injured limb can be accurately monitored to avoid tissue damage of the injured limb of the injured person.

[0037] The counter 204 is used to count the time the injured limb of the injured person is pressed, the time the injured limb is relaxed, and the number of times the pressed-relaxed cycle is passed, and transmit the result to the microprocessor 206. The counter 204 can count in a positive direction, that is, it can count from zero until a preset time or number of times is reached; the counter can also count in a negative direction, that is, it counts down from a preset time or number of times until the count returns to zero.

[0038] The information prompting unit 205 includes at least a buzzer and an LED light. The buzzer is used to output a voice prompt, and the LED light is used to output the prompt information in the form of light. Of course, a vibrator can also be used as an alarm, but when the vibrator outputs vibration information, a slight vibration may cause discomfort or pain to the injured person.

[0039] The microprocessor 206 processes the pulse information collected by the pulse sensor 203 and the count information of the counter 204. When it is detected that the pulse at the wrist or ankle of the injured limb of the injured person changes from being present to being absent, or from being absent to being present, a prompt message is output; the microprocessor 206 compares the count information of the counter 204 received with the preset time and number information to determine whether the current time and number have reached the preset time and number, and if so, a prompt message is output. The type of prompt message output can be preset or set by medical staff.

[0040] Since the network is not used in the process of information exchange between the monitoring device 20 and the medical staff or the injured, the present invention can be used even in the extreme case of network disconnection.

[0041] The battery 207 is used to power other components of the monitoring device 20. The battery 207 is a portable battery, such as a button battery, which can reduce the size and weight of the monitoring device 20 and make it easier to carry. Another advantage of using a portable battery is that it can last for a period of time even under extreme conditions of power outage. The microprocessor 206 can monitor the power level of the battery 207 in real time. When the power level of the battery 207 is lower than a certain value, a prompt message can be output in a flashing manner at the upper right corner of the display screen 202.

[0042] The monitoring device 20 also includes a second restraint (not shown), which is used to fix the monitoring device 20 at the distal end of the injured limb of the injured person. The second restraint includes two sub-bands with a certain length, one side of the first sub-band has a furry surface, and the other side of the second sub-band has a hook surface. In this way, by adjusting the bonding range of the furry surface and the hook surface of the two sub-bands of the second restraint, the monitoring device 20 can be fixed to different injured persons or different limb parts of the injured persons.

[0043] The tourniquet 10 and the monitoring device 20 can be placed in a packaging box or a packaging bag in pairs, and multiple packaging boxes or packaging bags can be integrated and placed in a large container, so that they can be carried separately or transported in an integrated manner.

[0044] The actual use process of the utility model is further described below.

[0045] The medical staff fixes the tourniquet 10 to the proximal end of the bleeding wound of the injured limb of the injured person.

[0046] The medical staff presses the switch button 2011 of the monitoring device 20 to start the monitoring device 20 .

[0047] The medical staff presses the time setting button 2012 according to the bleeding of the injured limb, and sets the pressing time, the relaxation time, and the number of pressing-relaxing cycles. When the injured is in a light condition, it can be set to one pressing and pressing time; when the injured is in a serious condition, the pressing time cannot be too long, and it can be set to a repeated cycle of pressing once, relaxing, pressing again, and relaxing.

[0048] The medical staff presses the information prompt setting button 2013 to set the output method of the prompt information according to the severity of the injury of the injured person. For example, when the injured person's injury is not serious and he can monitor the bleeding situation by himself, he can be set to output light prompt information; when the injured person's injury is serious and he cannot monitor the bleeding situation by himself and needs medical staff to monitor, it can be set to voice prompt information, so that the medical staff can know the bleeding situation of the injured person even if they are not with the injured person.

[0049] After the setting is completed, the medical staff fixes the monitoring device 20 at the distal end of the injured limb of the injured person. For example, when the injured limb is an upper limb, the monitoring device 20 can be fixed at the wrist of the injured upper limb, so that the pulse sensor 203 is close to the radial artery; when the injured limb is a lower limb, the monitoring device 20 can be fixed at the ankle or foot of the injured lower limb, so that the pulse sensor 203 is close to the foot artery. After being fixed, the monitoring device 20 starts to monitor the pulse of the injured person.

[0050] The medical staff repeatedly squeezes the pressure balloon 102, and compressed air continuously enters the balloon 101. As the pressure in the balloon 101 increases, the artery is compressed, resulting in a decrease in blood flow through the injured limb, and the pulse at the distal end of the injured limb becomes weaker and weaker. When there is no blood flowing, the pulse stops. Therefore, when the monitoring device 20 detects that the detection signal of the pulse sensor 203 changes from a signal to no signal, a voice prompt message such as "The pressure is enough, stop squeezing" is output to prompt the medical staff to stop squeezing.

[0051] During the process of maintaining pressure to stop bleeding, under normal circumstances, the detection signal of the pulse sensor 203 remains at zero. If the monitoring device 20 detects that the detection signal of the pulse sensor 203 changes from zero to a certain value, it indicates that there is a leak, resulting in insufficient pressure in the airbag 101, and the pressure needs to be increased. At this time, the monitoring device 20 outputs corresponding prompt information to remind the injured or medical staff. The medical staff re-squeezes the pressure balloon 102 to replenish the pressure of the airbag 101, and at the same time checks the cause of the air leakage of the tourniquet 10.

[0052] When the pre-set compression time of the medical staff arrives, the monitoring device 20 outputs corresponding prompt information to remind the injured or medical staff, such as outputting light information to the injured who are not seriously injured. If the bleeding is well stopped, the injured can stop bleeding by themselves; or outputting voice information such as "The compression time is up, come and deal with it", reminding the medical staff to proceed to the next step: if it is necessary to continue to stop bleeding, the medical staff will operate the exhaust valve 1013 of the airbag 101 to release or partially release the air in the airbag 101, and relax the injured limb for a short time to avoid necrosis of the injured limb tissue due to long-term compression. When the relaxation time is over, the medical staff will start to pressurize the airbag again, and the counter 204 will increase the number of cycles by 1, and enter the next compression-relaxation cycle.

[0053] In summary, the present invention designs the hemostasis 10 and the monitoring device 20 separately, and fixes the tourniquet and the monitoring device at the proximal end and the distal end of the injured limb respectively, so that the medical staff can operate the two without interfering with each other, thereby avoiding the pain that the injured person may experience during the operation; the tourniquet 10 and the monitoring device 20 do not use the network to exchange information, and can be used even under extreme conditions of network disconnection; there is no pressure sensor on the tourniquet 10, but a pulse sensor is set in the monitoring device 20, which can accurately monitor the hemostasis of the injured limb and avoid tissue damage to the injured limb of the injured person; the binding belt of the tourniquet 10 has both elastic parts and adhesive parts, which greatly increases the applicable population of the tourniquet 10; different prompt information types are set in the monitoring device 20 according to the injured person's injuries, so that people with lighter injuries can assist medical staff in monitoring their own hemostasis, ensuring that medical staff can focus on the treatment of people with serious injuries; the monitoring device 20 uses a battery as a power source, and can be used for a period of time even under extreme conditions of power outage, and is convenient to carry.
