Description

Technical Field

[0001] This utility model belongs to the field of medical emergency technology, specifically relating to a cricothyroid membrane puncture device. Background Technology

[0002] In the complex clinical scenarios of emergency medicine, emergencies such as head and facial trauma, upper airway obstruction, and laryngeal respiratory distress are like deadly killers lurking in the shadows, constantly threatening the lives of patients. These emergencies are often accompanied by the risk of acute airway obstruction. Once the airway is blocked, the patient will face the desperate situation of suffocation. Medical research clearly points out that for such life-threatening emergencies, rescuers must quickly establish an effective airway within the golden rescue window of 4-6 minutes. Otherwise, the patient will suffer irreversible brain damage or even death due to hypoxia.

[0003] Among numerous techniques for establishing airway access, cricothyroid membrane puncture stands out due to its unique advantages. Evidence-based medicine research provides a solid theoretical basis for it. The anatomical location of the cricothyroid membrane is very clear, with an average thickness of only 1.04±0.32mm. This characteristic makes the puncture operation highly accurate. At the same time, this procedure is highly efficient, with an average establishment time of only 42 seconds, which can buy patients a precious chance of survival in the shortest possible time. Therefore, cricothyroid membrane puncture has been clearly listed as the preferred technique for pre-hospital emergency care in the "Guidelines for Emergency Airway Management," occupying a crucial position in the field of emergency care.

[0004] However, despite the significant advantages of cricothyroid membrane puncture, the existing puncture devices on the market have many technical defects that urgently need to be addressed, which seriously restricts their efficient application in pre-hospital emergency care.

[0005] From the perspective of device design, current puncture devices are generally complex in structure. During the preoperative preparation stage, medical staff need to spend a lot of time assembling and debugging them, which increases the preoperative preparation time by 38%. In addition, the operating mechanism of current puncture devices also has obvious deficiencies. They fail to set up a graded force application structure based on the actual operation level of the operator. Without the assistance of a graded force application structure and in emergency situations, non-professionals often find it difficult to accurately grasp the force and rhythm of application, resulting in a low success rate. According to statistics, the success rate of non-professionals using current commercial puncture devices is less than 62%, which means that many patients cannot receive timely and effective airway management when they urgently need treatment. Utility Model Content

[0006] The purpose of this invention is to provide a cricothyroid membrane puncture device to solve the technical defects in the prior art, which is that the debugging process of the puncture device is not only time-consuming, but also that the current puncture device fails to set up a graded force application structure according to the actual operation level of the operator, resulting in a low success rate.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A cricothyroid membrane puncture device, comprising: Handheld propulsion component; The lower guide assembly is slidably connected to the handheld push assembly, and the lower guide assembly is provided with a force level adjustment component; A fastening component is located at the bottom of the lower guide component and is connected to the lower guide component; The puncture component is located within the handheld push component and is connected to the delivery component; When the hand-held pushing component moves along the length of the lower guide component, the puncture component and the force adjustment component are movably connected and extend into the fastening component.

[0008] Furthermore, the handheld pushing component includes: The push shell is a structure with one end open and the other end sealed, and pressing blocks are symmetrically provided on the inner side of the open end of the push shell; An elastic unit is sleeved on the outside of the puncture assembly, with its end abutting against the bottom of the two pressing blocks; The lower guide assembly includes: The guide shell has a sliding groove on its outer side, which pushes the open end of the shell to slide in the sliding groove; Limiting blocks are disposed on opposite sides of the guide shell; The protrusions are symmetrically arranged at the bottom of the wire housing and are connected to the fastening assembly; When the push shell moves in the sliding groove, it drives the elastic unit to make the puncture component abut against the top of the limiting block.

[0009] Furthermore, push rods are symmetrically provided on the sealing end of the push shell, and the push rods are perpendicular to the axial direction of the push shell.

[0010] Furthermore, a through hole is provided at the bottom of the guide shell, the fastening assembly is located below the through hole, and the puncture assembly is movably connected to the through hole.

[0011] Furthermore, the fastening assembly includes a support plate having a movable hole thereon, the movable hole axially coinciding with the through hole; Silicone pads are symmetrically arranged at the bottom of the support plate and located on both sides of the movable hole; A bonding plate is disposed at opposite ends of the support plate, and an elastic strap is connected to the end of the bonding plate, and the two elastic straps are bonded together.

[0012] Furthermore, the bonding plate has an arc-shaped structure.

[0013] Furthermore, the intensity level adjustment component includes: Mounting slots are provided on opposite sides of the lower guide component, and multiple slots are provided at intervals along the length of the lower guide component. A stop cone rod is disposed in one of the plurality of mounting slots, the end of which extends to the outside of the lower guide assembly.

[0014] Furthermore, the puncture assembly includes a needle tube 102, one end of which is disposed in the sealing end of the push shell, and the other end extends into the opening end and is provided with damping.

[0015] Furthermore, crossbars are symmetrically provided on the outer side of the guide shell.

[0016] Furthermore, the conveying assembly includes: The fixing sleeve is connected to the hand-held push assembly at one end and to the external infusion tube at the other end. A sealing ring is disposed on the inner wall of the fixing sleeve.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. During operation, medical staff only need to push the hand-held push component to move along the length of the lower guide component. With the assistance of the force adjustment component, the puncture component automatically completes the puncture and extends into the fastening component. Compared with the complex and step-by-step operation of traditional devices, this device greatly simplifies the operation process and reduces the difficulty of operation. Even inexperienced personnel can get started quickly, improving the convenience and operability of operation.

[0018] 2. Limiting blocks are set on both sides of the guide shell. When the push shell moves in the sliding groove, it drives the elastic unit to make the puncture component abut against the top of the limiting block. The limiting block plays a role in precise positioning, avoiding treatment failure or unnecessary damage to the patient due to insufficient or excessive puncture depth, and improving the accuracy and stability of puncture operation.

[0019] 3. The symmetrically arranged push rods provide the operator with two clear points of leverage, allowing the operator to operate the puncture assembly with greater force and more stable control.

[0020] 4. The through hole at the bottom of the guide shell provides a puncture channel for the puncture assembly. During the puncture process, the puncture assembly moves along the axial direction of the through hole, ensuring the accuracy of the puncture direction.

[0021] 5. The silicone pads, symmetrically arranged at the bottom of the support plate and on both sides of the movable hole, have good elasticity and softness, which can buffer the pressure of the puncture component on the patient's neck skin and tissues, reducing pain and discomfort during puncture.

[0022] 6. The curved structure of the adhesive plate can better conform to the physiological curve of the neck and fit closely to the surface of the neck. Compared with the flat structure of the adhesive plate, it greatly increases the contact area with the neck.

[0023] 7. Because the mounting slots are arranged at intervals along the length of the lower guide component, medical staff can quickly and conveniently switch between different gears during actual operation.

[0024] 8. Damping can reduce the impact force when the needle 102 is inserted, making the stimulation of the neck tissue by the needle 102 gentler. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] In the description of the embodiments of this utility model, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the utility model. Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] To address the technical deficiencies mentioned in the background section, this embodiment provides a cricothyroid membrane puncture device. The present invention will be further described in detail below with reference to the accompanying drawings: like Figures 1-3 As shown, the device includes a handheld pushing component 1; a lower guide component 2, slidably connected to the handheld pushing component 1, and a force adjustment component in the lower guide component 2; a fastening component 6, located at the bottom of the lower guide component 2 and communicating with it; and a puncture component, located in the handheld pushing component 1 and connected to a delivery component 3. When the handheld pushing component 1 moves along the length of the lower guide component 2, the puncture component is movably connected to the force adjustment component and extends into the fastening component 6. During operation, medical personnel only need to push the handheld pushing component 1 along the length of the lower guide component 2. With the assistance of the force adjustment component, the puncture component extends into the fastening component 6 and automatically completes the puncture operation. Compared to the complex and multi-step operation of traditional devices, this device significantly simplifies the operation process, reduces the difficulty of operation, and allows even inexperienced personnel to quickly learn how to use it, improving the convenience and operability of operation.

[0035] In addition, the force adjustment component in the lower guide assembly 2 provides multiple force levels to choose from, depending on the specific condition of different patients and the operator's skill level. During the puncture, the force adjustment component helps the operator to accurately control the amount of force applied, avoiding excessive damage to the patient's airway tissue due to excessive force, or insufficient puncture due to insufficient force, thereby ensuring the safety and effectiveness of the puncture operation.

[0036] The fastening component 6 is located at the bottom of the lower guide component 2 and is connected to the lower guide component 2, providing stable support and guidance for the puncture process. During puncture, the fastening component 6 can be fixed to the patient's neck on the one hand, and ensure that the puncture direction is accurate on the other hand, preventing puncture deviation, ensuring puncture accuracy, reducing the risk of complications caused by puncture direction deviation, and further improving the safety of puncture operation. Moreover, it can complete the puncture operation more accurately, improve the success rate of operation, and enable more patients to receive timely and effective airway management when they urgently need treatment.

[0037] With the above-mentioned structural design, the puncture device can be applied to a variety of pre-hospital emergency scenarios, such as accident scenes and outdoor rescues. In these emergency and complex environments, medical staff can quickly and accurately use the device to establish an airway for patients, meet the needs of different emergency scenarios, and strive for more survival opportunities for patients.

[0038] like Figure 1As shown, the handheld pushing component 1 includes a pushing shell 101, which is an open-end and closed-end structure. Pressing blocks 103 are symmetrically arranged on the inner side of the open end of the pushing shell 101. An elastic unit 4 is sleeved on the outside of the puncture component, and its end abuts against the bottom of the two pressing blocks 103. When the pushing shell 101 moves downward, the two pressing blocks 103 can squeeze the elastic unit 4 to drive the puncture component to move downward.

[0039] As shown in the figure, the lower guide assembly 2 includes a guide shell 201, which consists of two identical parts, both of which are fixedly connected to the fastening assembly 6 via protrusions 204. A sliding groove 202 is provided on the outer wall of the guide shell 201, and the open end of the push shell 101 slides in the sliding groove 202. Limiting blocks 203 are provided on opposite sides of the guide shell 201. When the push shell 101 moves downward in the sliding groove 202 to perform a puncture operation, it can simultaneously drive the elastic unit 4 to make the puncture assembly abut against the top of the limiting block 203, thus completing the puncture operation while avoiding damage to the patient's body.

[0040] Because the guide shell 201 has a sliding groove 202 and a crossbar on its outer side, the open end of the push shell 101 can slide in the sliding groove 202. This sliding guide structure provides the operator with a clear operating trajectory, making the pushing action more stable and smooth. The operator only needs to push the push shell 101 along the direction of the sliding groove 202 to complete the puncture operation. There is no need for complicated operating methods or skills, which reduces the difficulty of operation and improves the convenience of operation. Especially in emergency pre-hospital emergency scenarios, it can quickly and accurately perform puncture.

[0041] The limiting block 203 plays a precise positioning role, ensuring that the puncture component can reach the predetermined puncture position every time, guaranteeing the accuracy of puncture depth and direction, avoiding treatment failure or unnecessary damage to the patient due to insufficient or excessive puncture depth, and improving the accuracy and stability of puncture operation.

[0042] The elastic unit 4 is sleeved on the outside of the puncture assembly, and its end abuts against the bottom of the two pressing blocks 103. When the push shell 101 is pushed to perform the puncture operation, the elastic unit 4 can play a buffering role, making the puncture process more stable and reducing the impact on the patient. At the same time, the elasticity of the elastic unit 4 also helps the operator to better control the puncture force, further improving the accuracy and stability of the operation.

[0043] like Figure 1 As shown, the push shell 101 has a Y-shaped structure, with push rods symmetrically arranged on its sealing end. The push rods are perpendicular to the axis of the push shell 101, allowing the operator to more intuitively feel the magnitude and direction of the applied force, which facilitates precise control of the pushing force.

[0044] Furthermore, the bottom of the guide shell 201 has a through hole, and the fastening component 6 is located below the through hole. The piercing component is movably connected to the through hole, providing a clear piercing channel for the piercing component. During the piercing process, the piercing component moves along the axial direction of the through hole, ensuring the accuracy of the piercing direction. At the same time, because the piercing component is movably connected to the through hole, during operation, the piercing component is constrained by the through hole and can only move on a predetermined trajectory, reducing piercing errors caused by factors such as operator hand tremors or uneven force application, making the piercing operation more stable and reliable.

[0045] The fastening assembly 6 includes a support plate 601 with a movable hole 602 axially aligned with a through hole; silicone pads 603 symmetrically positioned at the bottom of the support plate 601 on either side of the movable hole 602; and adhesive plates 604 positioned at opposite ends of the support plate 601, with elastic straps 605 connected to the ends of the adhesive plates 604, the two elastic straps 605 being bonded together. The movable hole 602 provides a certain degree of restraint to the puncture assembly. After puncture, the puncture assembly is positioned within the movable hole 602, reducing the shaking of the puncture assembly. This is crucial for maintaining the stability of the puncture site, especially when the patient may move slightly due to pain or breathing, effectively preventing displacement of the puncture assembly and ensuring the puncture effect.

[0046] During the puncture, the silicone pad 603 cushions the pressure of the puncture components on the patient's neck skin and tissues, reducing pain and discomfort. Simultaneously, the silicone pad 603 also provides protection, preventing direct contact between the support plate 601 and the patient's skin from causing friction damage, thus improving patient comfort. The elastic band 605 connected to the end of the fitting plate 604 can adaptively adjust according to the patient's neck size. The elastic band 605 has a certain degree of elasticity, allowing it to fit snugly and comfortably around the patient's neck, avoiding both excessive tightness causing pain and excessive looseness causing the device to shift. This comfortable fit reduces patient tension and discomfort during the puncture process, facilitating a smooth procedure.

[0047] The two elastic bandages 605 are connected by an adhesive method, which is simple and reliable and can provide sufficient fixation force. After the puncture is completed, the elastic bandages 605 firmly fix the entire fastening component 6 to the patient's neck, preventing the device from shifting due to patient movement or external factors, ensuring the stability of the puncture site, and providing a guarantee for subsequent treatment and care.

[0048] Specifically, the fitting plate 604 has an arc-shaped structure, which can better fit the neck area; the ends of the two elastic straps 605 are provided with adhesive layers 606, and the strong adhesive force of the two adhesive layers 606 makes the two elastic straps 605 firmly fastened together.

[0049] like Figure 3 As shown, the force adjustment component includes a mounting groove 205, which is opened on both sides of the lower guide component 2 and multiple grooves are arranged at intervals along the length of the lower guide component 2; and a stop cone rod 206 is disposed in the multiple mounting grooves 205, with its end extending to the outside of the lower guide component 2.

[0050] In operation, the stop cone rod 206 is plugged into the mounting groove 205. The puncture assembly includes a needle tube 102, one end of which is located in the sealing end of the push shell 101, and the other end extends into the opening end and is equipped with damping 5. Before the puncture operation, the puncture force can be estimated in advance according to the patient's age, physical condition and illness, and the end of the stop cone rod 206 corresponding to the force can be pressed and pushed accordingly, so that the conical end of the stop cone rod 206 extends into the guide shell 201. During the movement of the needle tube 102, the stop cone rod 206 can resist the damping 5 on the needle tube 102.

[0051] The end of the handheld push assembly 1 away from the lower guide assembly 2 is equipped with a delivery assembly 3. The delivery assembly 3 includes a fixed sleeve and a sealing ring. One end of the fixed sleeve is connected to the handheld push assembly 1, and the other end is connected to the external infusion tube. The sealing ring is set on the inner wall of the fixed sleeve to prevent leakage of the medicine.

[0052] In summary, this cricothyroid membrane puncture device, through innovative designs such as optimized structural design and the addition of force adjustment components, effectively solves the problems existing in existing puncture devices. It has many beneficial effects, such as simplifying preoperative preparation, improving the success rate of operation, lowering the operation threshold, and ensuring puncture accuracy and safety, and has broad application prospects in the field of pre-hospital emergency care.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit its protection scope. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that after reading this utility model, they can still make various changes, modifications or equivalent substitutions to the specific implementation of the utility model, but these changes, modifications or equivalent substitutions are all within the protection scope of the pending claims of the utility model.
