Description

Technical Field

[0001] The present invention relates to the technical field of medical puncture instruments, and particularly relates to a cricothyroid membrane puncture first-aid device with lighting and oxygen supply functions and a usage method thereof. Background Art

[0002] In first-aid medical scenarios, cricothyroid membrane puncture is an important first-aid measure for quickly establishing an airway and relieving patients' dyspnea. To overcome related technical problems, those skilled in the art have continuously explored. For example, the rotary blood department bone marrow puncture needle with the Chinese patent publication number CN109009249A can reduce the number of punctures, avoid puncture needle blockage and sampling contamination, but still has the following problems: Firstly, it has a single function. Traditional devices only have the puncture function and lack auxiliary functions such as lighting and oxygen supply, which are difficult to meet the complex first-aid needs and reduce the first-aid efficiency and success rate. Secondly, the lighting condition is poor. In a dim environment, medical staff are difficult to accurately judge the puncture position and depth, which affects the puncture success rate and may even cause additional harm to patients and delay first aid. Thirdly, the oxygen supply is not timely. After successful puncture, traditional devices cannot supply oxygen immediately. During the golden first-aid time, patients may be damaged due to hypoxia and endanger their lives, highlighting the shortcoming of traditional devices in oxygen supply. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: to overcome the deficiencies of the prior art and provide a cricothyroid membrane puncture first-aid device with lighting and oxygen supply functions and a usage method thereof.

[0004] The technical solution adopted by the present invention is as follows: A cricothyroid membrane puncture first-aid device with lighting and oxygen supply functions includes an integrated liquid extractor, a puncture needle assembly, a rotary joint sleeve, and a gas supply needle assembly, wherein: The liquid extractor includes a syringe barrel and a needle pusher and a piston arranged inside the syringe barrel; a power supply assembly is installed on the side of the syringe barrel, and several lighting lamps are arranged at the bottom of the syringe barrel facing the puncture needle assembly direction; the power supply assembly is respectively connected to the lighting lamps; The puncture needle assembly includes a tracheal passage and a puncture needle arranged inside the tracheal passage; the tracheal passage includes an upper end joint matched with the syringe barrel, an oxygen supply joint matched with the gas supply needle assembly, and a sleeve matched with the puncture needle; The rotary joint sleeve includes a joint sleeve body and a strap fixing ring obliquely arranged on the periphery of the joint sleeve body; the joint sleeve body is sleeved outside the tracheal passage and a fixing hole for the oxygen supply joint is reserved; a buckle for the strap to pass through is reserved between the strap fixing ring and the joint sleeve body; The air supply needle assembly includes an air supply needle, a sealing pad and a connecting cover which are arranged in sequence from the inside to the outside; the air inlet end of the air supply needle is connected to the oxygen supply conduit, and the air outlet end of the air supply needle is inserted into a silicone plug in the oxygen supply connector; the connecting cover is fixedly connected to the oxygen supply connector through threads.

[0005] This technical solution integrates the lighting, oxygen supply and puncture functions into one, reducing the equipment and operating steps required during the first aid process and improving the efficiency of first aid. For example, in an emergency, medical staff no longer need to prepare lighting equipment and oxygen supply equipment separately. They only need to use this device to complete the puncture, lighting and oxygen supply operations, which greatly shortens the first aid time and wins precious treatment time for patients. Compared with traditional devices, this device can immediately supply oxygen to patients after a successful puncture, avoiding hypoxia damage caused by untimely oxygen supply, and improving the patient's chance of survival and recovery quality. The built-in high-brightness LED light and intelligent photosensitive chip can automatically adjust the brightness according to the ambient light, ensuring sufficient lighting under various lighting conditions and improving the success rate of puncture.

[0006] In addition, the cricothyroid membrane puncture emergency device with lighting and oxygen supply functions according to the present invention also has the following additional technical features: According to one embodiment of the present invention, the power supply component includes a button battery and a button, and the two sides of the button battery are limited on the limit platform inside the button through the negative plate and the positive plate respectively; the positive plate and the negative plate are respectively connected to the positive and negative poles of the lighting lamp below through wiring.

[0007] In this technical solution, the button battery and the button are compactly integrated into the side of the syringe, which does not take up too much space and does not affect the overall use and portability of the device. The light is turned on and off by the button, which is simple and convenient to operate. It can be operated quickly in an emergency without complicated steps, which improves the efficiency of first aid.

[0008] According to one embodiment of the present invention, the lighting lamps are evenly distributed around the periphery of the bottom of the syringe which is arranged in a columnar shape; the lighting lamps include LED lamps and photosensitive chips, and the photosensitive chip automatically adjusts the brightness according to the ambient light to project sufficient light toward the puncture needle.

[0009] In this technical solution, the photosensitive chip is composed of multiple photosensors. The photosensitive chip monitors the ambient light in real time and feeds back the information to the LED lamp drive circuit. The drive circuit adjusts the brightness of the LED lamp according to the feedback information to ensure that the lighting lamp can always provide appropriate light intensity. In a dim environment, the photosensitive chip will detect that the light is weak, thereby increasing the current of the LED lamp and improving its brightness; in a bright environment, the photosensitive chip will detect that the light is strong, thereby reducing the current of the LED lamp and reducing its brightness.

[0010] According to one embodiment of the present invention, the tracheal channel is arranged in a Y shape, the oxygen supply connector is located on the side of the upper end connector and the angle between the two is an acute angle, and oxygen enters the tracheal channel from the oxygen supply connector via the air supply needle at an angle; the sleeve is arranged in an arc shape with the same bending degree as the puncture needle; the oxygen supply connector is equipped with a silicone plug that matches the air supply needle.

[0011] In this technical solution, the tilt angle guides oxygen to enter the tracheal passage more smoothly, reducing airflow turbulence and energy loss; the arc of the sleeve matches the bending degree of the puncture needle, which can provide stable support for the puncture needle and prevent the puncture needle from deflecting or shaking during use. The sleeve wraps the upper part of the puncture needle.

[0012] According to one embodiment of the present invention, the upper end connector is connected to a liquid extractor for extracting sputum; or, the upper end connector is connected to a positive pressure ventilator for providing breathing.

[0013] In this technical solution, the upper end connector is connected to the aspirator, which drives the piston to pull outward through the needle push to form negative pressure, and the sputum in the patient's airway is sucked into the syringe; when the patient's own respiratory function is insufficient and effective gas exchange cannot be maintained, a positive pressure ventilator is needed to provide respiratory support; the positive pressure ventilator helps the patient complete breathing movements and improve ventilation and oxygenation by delivering gas of a certain pressure and flow into the patient's airway.

[0014] According to one embodiment of the present invention, a plurality of air holes are provided on the puncture needle, and oxygen supply and atomization drug administration are synchronously performed by using the air holes during puncture, and sputum suction is synchronously performed while oxygen supply; the sputum is connected to the syringe through the upper end connector.

[0015] In this technical solution, the pores are not only used for oxygen supply and atomization, but also play a key role in sputum suction. The pores serve as the entrance for sputum to enter the puncture needle, so that the sputum suction operation can be performed directly in the airway, improving the efficiency of sputum suction. Continuous oxygen supply ensures the patient's oxygenation state and avoids hypoxia caused by sputum suction. The two are carried out simultaneously, which not only ensures the patient's breathing safety, but also effectively removes sputum in the airway.

[0016] According to one embodiment of the present invention, the oxygen supply conduit is made of polyurethane and is connected to the oxygen supply and drug administration interface of the emergency jet ventilator.

[0017] In this technical solution, the polyurethane material has good biocompatibility and chemical stability, and will not break easily or affect the delivery of oxygen and drugs. Through the connection between the oxygen supply conduit and the ventilator interface, the emergency jet ventilator can accurately control the flow of oxygen and drugs.

[0018] According to an embodiment of the present invention, the power supply assembly and the oxygen supply connector are both arranged on the side where the puncture needle is bent; when holding the syringe barrel for cricothyroid membrane puncture operation, the side of the power supply assembly and the oxygen supply connector is a non-interference area.

[0019] In this technical solution, when performing cricothyroid membrane puncture operation, it is usually necessary to hold the syringe barrel with one hand or both hands and insert the puncture needle into the cricothyroid membrane at a certain angle and force; arranging the power supply assembly and the oxygen supply connector on the side where the puncture needle is bent is based on the ergonomic principle, so that when medical staff hold the syringe barrel, the natural placement positions of the fingers and palms will not interfere with these components. The structure of the syringe conforms to the natural posture of human hand holding, and it is easier and more accurate to exert force.

[0020] To achieve the above object, the present invention also provides a method for using a cricothyroid membrane puncture first aid device with lighting and oxygen supply functions.

[0021] A method for using a cricothyroid membrane puncture first aid device with lighting and oxygen supply functions includes the following steps: S1. Take out the device from the packaging bag. The syringe, the puncture needle assembly, the rotary joint sleeve and the gas supply needle assembly of the device have been pre-assembled. S2. Turn on the emergency jet ventilator and connect it to the gas supply needle assembly through the oxygen supply catheter. S3. Press the button of the power supply assembly. The lighting lamp automatically adjusts the brightness according to the ambient light to provide sufficient illumination; hold the patient's neck with one hand and hold the syringe barrel of the syringe with the other hand and puncture the cricothyroid membrane of the patient using the puncture needle assembly. S4. During puncture, use the gas supply needle assembly to supply oxygen and atomize medicine synchronously, and use the syringe to aspirate sputum synchronously while supplying oxygen. S5. After the syringe aspirates the sputum, remove the syringe from the puncture needle assembly and connect the puncture needle assembly to the positive pressure ventilator. S5. Adjust the tightness of the strap using the strap fixing ring and leave the device on the patient; at this time, the positive pressure ventilator provides respiratory support and the gas supply needle assembly provides oxygen and atomized medicine.

[0022] This technical solution integrates the lighting and oxygen supply functions, effectively solves the problem of single function of traditional devices, enables medical staff not to need to prepare additional lighting and oxygen supply equipment during the first aid process, reduces the operation steps and time, and improves the first aid efficiency.

[0023] Compared with the prior art, the present invention has the following beneficial effects: (1) Integrates the lighting and oxygen supply functions, effectively solving the problem of single function of traditional devices; (2) It is equipped with a high-brightness LED lamp and an intelligent photosensitive chip, which can automatically adjust the brightness according to the ambient light, facilitating accurate operations such as puncture.

Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Embodiment 1 As Figures 1 to 4 shown, this embodiment provides a cricothyrotomy first-aid device with lighting and oxygen supply functions, including a syringe 1, a puncture needle assembly 2, a rotary joint sleeve 3, and a gas supply needle assembly 4 integrated together, where: As Figure 5 shown, the syringe 1 includes a syringe barrel 11, a plunger rod 12, and a piston 15 disposed inside the syringe barrel 11; a power supply assembly 13 is installed on the side of the syringe barrel 11, and a plurality of lighting lamps 14 are disposed at the bottom of the syringe barrel 11 facing the puncture needle assembly 2; the power supply assembly 13 is respectively connected to the lighting lamps 14; As Figure 6 shown, the puncture needle assembly 2 includes a tracheal passage 21 and a puncture needle 22 disposed inside the tracheal passage 21; as Figures 7 to 8 shown, the tracheal passage 21 includes an upper end joint 211 that mates with the syringe barrel 11, an oxygen supply joint 212 that mates with the gas supply needle assembly 4, and a sleeve 213 that mates with the puncture needle 22; As Figure 9 shown, the rotary joint sleeve 3 includes a joint sleeve body 31 and a strap fixing ring 32 inclinedly disposed on the periphery of the joint sleeve body 31; the joint sleeve body 31 is sleeved outside the tracheal passage 21 and a fixing hole for the oxygen supply joint 212 is reserved; a buckle for the strap to pass through is reserved between the strap fixing ring 32 and the joint sleeve body 31; As Figure 10 and Figure 11 shown, the gas supply needle assembly 4 includes a gas supply needle 41, a gasket 42, and a connection cover 43 sequentially arranged from the inside to the outside; the intake end of the gas supply needle 41 is connected to an oxygen supply conduit 5, and the outlet end of the gas supply needle 41 is inserted into a silica gel plug inside the oxygen supply joint 212; the connection cover 43 is fixedly connected to the oxygen supply joint 212 by threads.

[0038] As Figures 1 to 11As shown, this technical solution integrates lighting, oxygen supply, and puncture functions, reducing the equipment and operation steps required during first aid and improving the efficiency of first aid. For example, in an emergency, medical staff no longer need to separately prepare lighting equipment and oxygen supply equipment. They can simply use this device to complete puncture, lighting, and oxygen supply operations, greatly shortening the first aid time and winning precious treatment opportunities for patients. Compared with traditional devices, this device can immediately supply oxygen to patients after successful puncture, avoiding hypoxia damage caused by untimely oxygen supply and improving the survival rate and rehabilitation quality of patients. The built-in high-brightness LED lights and intelligent light-sensitive chips can automatically adjust the brightness according to the ambient light, ensuring sufficient lighting under various lighting conditions and increasing the success rate of puncture.

[0039] In addition, the cricothyroid membrane puncture first aid device with lighting and oxygen supply functions proposed above according to the present invention also has the following additional technical features: According to an embodiment of the present invention, the power supply component 13 includes a button battery 131 and a button 134. The two sides of the button battery 131 are respectively limited on the limiting platform 135 inside the button 134 through a negative plate 132 and a positive plate 133; the positive plate 133 and the negative plate 132 are respectively connected to the positive and negative electrodes of the lower lighting lamp 14 through wires.

[0040] In this technical solution, the button battery 131 and the button 134 are compactly integrated on the side of the syringe 11, without occupying too much space and not affecting the overall use and carrying of the device. The lighting lamp 14 is controlled to be turned on and off through the button 134, and the operation is simple and convenient. In an emergency, it can be quickly operated without complicated steps, improving the efficiency of first aid.

[0041] According to an embodiment of the present invention, the lighting lamps 14 are evenly distributed on the periphery of the bottom of the columnar syringe 11; the lighting lamp 14 includes an LED lamp and a light-sensitive chip, and the light-sensitive chip automatically adjusts the brightness according to the ambient light and projects sufficient light toward the puncture needle 22.

[0042] In this technical solution, the light-sensitive chip is composed of multiple photosensitive sensors. The light-sensitive chip monitors the ambient light in real time and feeds back the information to the driving circuit of the LED lamp. The driving circuit adjusts the brightness of the LED lamp according to the feedback information to ensure that the lighting lamp 14 can always provide an appropriate light intensity. In a dim environment, the light-sensitive chip will detect weak light, thus increasing the current of the LED lamp to increase its brightness; in a bright environment, the light-sensitive chip will detect strong light, thus reducing the current of the LED lamp to reduce its brightness.

[0043] According to an embodiment of the present invention, the tracheal channel 21 is arranged in a Y shape. The oxygen supply joint 212 is located on the side of the upper joint 211 and the included angle between them is an acute angle. Oxygen enters the tracheal channel 21 obliquely from the oxygen supply joint 212 via the gas supply needle 41. The sleeve 213 is arranged in an arc shape that is consistent with the bending degree of the puncture needle 22. A silica gel plug that cooperates with the gas supply needle 41 is built into the oxygen supply joint 212.

[0044] In this technical solution, the inclination angle guides oxygen to enter the tracheal channel 21 more smoothly, reducing the turbulence of the air flow and energy loss. The arc shape of the sleeve 213 matches the bending degree of the puncture needle 22, which can provide stable support for the puncture needle 22 and prevent the puncture needle 22 from shifting or shaking during use. The sleeve 213 wraps the upper half of the puncture needle 22.

[0045] According to an embodiment of the present invention, the upper joint 211 is connected to the aspirator 1 for aspirating sputum; alternatively, the upper joint 211 is connected to a positive pressure ventilator for providing respiration.

[0046] In this technical solution, the upper joint 211 is connected to the aspirator 1. The aspirator 1 drives the piston 15 to pull outwards through the needle push 12 to form a negative pressure, and the sputum in the patient's airway is aspirated into the syringe barrel 11. When the patient's own respiratory function is insufficient to maintain effective gas exchange, it is necessary to rely on a positive pressure ventilator to provide respiratory support. The positive pressure ventilator helps the patient complete the breathing action by delivering a certain pressure and flow of gas into the patient's airway, improving ventilation and oxygenation.

[0047] According to an embodiment of the present invention, a plurality of air holes are provided on the puncture needle 22. During puncture, oxygen supply and atomized drug delivery are carried out synchronously through the air holes, and sputum aspiration is carried out simultaneously while supplying oxygen. The sputum is connected to the syringe barrel 11 through the upper joint 211.

[0048] In this technical solution, the air holes are not only used for oxygen supply and atomized drug delivery, but also play a key role during sputum aspiration. The air holes serve as the entrance for sputum to enter the puncture needle 22, enabling sputum aspiration to be directly carried out in the airway, improving the efficiency of sputum aspiration. Continuous oxygen supply ensures the patient's oxygenation status and avoids hypoxia caused by sputum aspiration. The two are carried out synchronously, ensuring the patient's respiratory safety and effectively clearing the sputum in the airway.

[0049] According to an embodiment of the present invention, the oxygen supply catheter 5 is made of polyurethane material and is connected to the oxygen supply and drug delivery interfaces of the emergency jet ventilator.

[0050] In this technical solution, the polyurethane material has good biocompatibility and chemical stability and will not break easily or affect the delivery of oxygen and drugs. By connecting the oxygen supply catheter 5 to the ventilator interface, the emergency jet ventilator can precisely control the flow rates of oxygen and drugs.

[0051] According to an embodiment of the present invention, the power supply assembly 13 and the oxygen supply connector 212 are both arranged on the side where the puncture needle 22 is bent; when holding the syringe barrel 11 to perform cricothyroid membrane puncture operation, one side of the power supply assembly 13 and the oxygen supply connector 212 is a non-interference area.

[0052] In this technical solution, when performing cricothyroid membrane puncture operation, usually one hand or both hands are used to hold the syringe barrel 11, and the puncture needle 22 is inserted into the cricothyroid membrane at a certain angle and force; arranging the power supply assembly 13 and the oxygen supply connector 212 on the side where the puncture needle 22 is bent is based on the ergonomic principle, so that when the medical staff holds the syringe barrel 11, the natural placement positions of the fingers and palm will not interfere with these components. The structure of the syringe 1 conforms to the natural posture of human hand holding, and the force can be exerted more easily and accurately.

[0053] Embodiment 2 On the basis of Embodiment 1, as Figures 1 to 11 shown, this embodiment provides a usage method of a cricothyroid membrane puncture first aid device with lighting and oxygen supply functions, including the following steps: S1. Take out the device from the packaging bag. The syringe 1, the puncture needle assembly 2, the rotary joint sleeve 3 and the gas supply needle assembly 4 of the device have been pre-assembled. S2. Turn on the emergency jet ventilator and connect it to the gas supply needle assembly 4 through the oxygen supply conduit 5. S3. Press the key 134 of the power supply assembly 13. The lighting lamp 14 automatically adjusts the brightness according to the ambient light to provide sufficient illumination; hold the patient's neck with one hand, and hold the syringe barrel 11 of the syringe 1 with the other hand and puncture the cricothyroid membrane of the patient by using the puncture needle assembly 2. S4. During puncture, use the gas supply needle assembly 4 to supply oxygen and atomize drugs synchronously, and use the syringe 1 to aspirate sputum synchronously while supplying oxygen. S5. After the syringe 1 aspirates the sputum, remove the syringe 1 from the puncture needle assembly 2, and connect the puncture needle assembly 2 to the positive pressure ventilator. S5. Adjust the tightness of the strap by using the strap fixing ring 32, and leave the device on the patient; at this time, the positive pressure ventilator provides respiratory support, and the gas supply needle assembly 4 provides oxygen and atomizes drugs.

[0054] This technical solution integrates the lighting and oxygen supply functions, effectively solves the problem of single function of the traditional device, enables the medical staff to no longer need to prepare additional lighting and oxygen supply equipment during the first aid process, reduces the operation steps and time, and improves the first aid efficiency.

Without departing from the spirit and essence of the present invention, those of ordinary skill in the art may make various equivalent modifications or substitutions to the embodiments of the present invention, and such modifications or substitutions should all fall within the scope of the present invention. / Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
