Description

Technical Field

[0001] The utility model relates to the technical field of airway models, and particularly relates to a detection device for identifying cricothyroidotomy ventilation. Background Art

[0002] Cricothyroidotomy is an emergency tracheotomy for critically ill patients with acute laryngeal obstruction. Generally, after the dyspnea is relieved by this operation, a routine tracheotomy is performed. A transverse incision is made between the thyroid cartilage and the cricoid cartilage, the anterior cervical muscles are separated, the cricothyroid membrane is felt clearly, the cricothyroid membrane is incised transversely about 1 cm with a small knife, and the incision is opened with a knife handle or a hemostatic forceps to establish a ventilation tract. Therefore, it is crucial for doctors to master cricothyroidotomy proficiently.

[0003] For learning and practicing cricothyroidotomy, simulation tools are essential. For existing simulation tools, most of them are disposable tools. After being used multiple times, the entire airway model needs to be remade, which will result in a high training cost. Moreover, the existing simulation tools are default to directly install the plug, and cannot be used to detect the conventional unblocked situation, so the teaching effect is poor.

[0004] Therefore, how to provide a detection device for identifying cricothyroidotomy ventilation to solve the high use cost of existing simulation tools is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Utility Model

[0005] For this reason, the utility model provides a detection device for identifying cricothyroidotomy ventilation to solve the problems of poor teaching effect and high use cost caused by the low reusability of simulation tools and the inability to simulate various situations in the prior art.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

Specific implementation mode

[0041] The following specific embodiments illustrate the implementation mode of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0042] Please refer to Figures 1 - 6 , and now a detection device for identifying cricothyrotomy ventilation disclosed by the present utility model will be described. The present utility model is composed of six parts, as Figure 1 , including thyroid cartilage 1, simulation component 2, clamping component 3, installation clamping piece 4, detection component 5 and connecting piece 6. The left end of the thyroid cartilage 1 is internally inserted with the connecting piece 6, and the left end of the connecting piece 6 is connected to the air supply system. The installation clamping piece 4 is installed at the lower right of the thyroid cartilage 1, the right end of the installation clamping piece 4 is installed with the clamping component 3, the right end of the clamping component 3 is connected to the detection system, the detection component 5 is installed at the front end of the installation clamping piece 4, the left and right ends of the simulation component 2 are respectively clamped in the thyroid cartilage 1 and the clamping component 3, the bottom of the simulation component 2 is clamped in the installation clamping piece 4, the thyroid cartilage 1, the installation clamping piece 4 and the clamping component 3 are integrally formed, an installation space is formed between the thyroid cartilage 1, the installation clamping piece 4 and the clamping component 3, and the simulation component 2 is inserted into the installation space.

[0043] When the utility model is in use, it is divided into two usage scenarios. The first is for non-cricothyroidotomy ventilation. The simulation component 2 without the detection piece 26 and the baffle 27 is installed in the installation space. During installation, the two connecting rings 21 are respectively stuck in the first arc groove 11 and the second arc groove 31, and then the insertion block 23 is inserted into the rectangular groove 41 to complete the installation of the simulation component 2. After installation, the connector 6 is used to connect the mask or the intubation tube of the air supply system, and the clamping component 3 is connected to the pipeline of the detection system. At this time, the air pump of the air supply system provides gas. Since there is no baffle 27, the gas can flow through the simulation component 2 normally and the detection system can detect the gas. After detecting the gas, it can be recognized as non-cricothyroidotomy ventilation. Because the gas flow area is different, the detected pressure is also different. The second is for the cricothyroidotomy ventilation state. Since the detection piece 26 and the baffle 27 are installed in the simulation component 2, during installation, the detection piece 26 needs to be installed in the installation groove 55 first, then the two connecting rings 21 are respectively stuck in the first arc groove 11 and the second arc groove 31, and then the insertion block 23 is inserted into the rectangular groove 41. At this time, the detection piece 26 acts as a trigger switch to contact the detection block 53 to generate a signal, and the signal is transmitted to the PCB board 54 through the transmission rod 52. The PCB board 54 gives a feedback and judges that the cricoid cartilage 24 is in a blocked state. At the same time, the gas provided by the air supply system cannot be detected by the detection system, and cricothyroidotomy is required. A scalpel is used to cut the arc-shaped opening at the left end of the cricoid cartilage 24. The arc-shaped opening is the cricothyroid membrane. After cutting, a needle is inserted, and the needle is connected to the air pump to introduce air through the incision. At this time, the detection system detects the gas signal again. However, because the gas has a small volume and the pressure will increase, the detection system will detect a gas pressure signal different from the normal state.

[0044] In a specific embodiment, such as Figure 2 , the simulation component 2 includes connecting rings 21, a circular trachea 22, insertion blocks 23, a cricoid cartilage 24, and clamping rings 25. The left end of the circular trachea 22 is connected to the cricoid cartilage 24. The connecting rings 21 are arranged in pairs and are respectively installed on the right side of the circular trachea 22 and the left side of the cricoid cartilage 24. The clamping rings 25 are arranged in pairs and are installed on the outer sides of the two connecting rings 21. The clamping rings 25 are clamped in the thyroid cartilage 1 and the clamping component 3. The insertion blocks 23 are arranged in pairs and are installed below the circular trachea 22 and the cricoid cartilage 24. The left and right ends of the insertion blocks 23 are respectively connected to the clamping rings 25, and the insertion blocks 23 are inserted into the installation fasteners 4. The designs of the cricoid cartilage 24 and the circular trachea 22 are both for simulating the human trachea. Because of its realistic effect, it can be used alone or added to various simulation medical models including cricothyroidotomy training. The designs of the insertion blocks 23 and the clamping rings 25 are for facilitating the installation and disassembly of the simulation component 2. This way, when the simulation component 2 cannot be used, only the simulation component 2 needs to be replaced, effectively saving the production cost.

[0045] In a specific embodiment, such as Figure 3 , the simulation component 2 further includes a detection piece 26 and a baffle 27. The baffle 27 is installed in the left clamping ring 25, and the detection piece 26 is installed at the lower end of the front plug 23. The design of the baffle 27 is used to simulate the airway occlusion situation, and the detection piece 26 and the baffle 27 appear on the same simulation component 2 simultaneously.

[0046] In a specific embodiment, such as Figure 4 , a first circular arc groove 11 is opened inside the right end of the thyroid cartilage 1, a second circular arc groove 31 is opened inside the left end of the clamping component 3, a rectangular groove 41 is opened inside the mounting clip 4, and the first circular arc groove 11, the second circular arc groove 31 and the rectangular groove 41 are connected and form a mounting space. Through the design of the first circular arc groove 11, the second circular arc groove 31 and the rectangular groove 41, it is not only convenient for the disassembly and installation of the simulation component 2, but also can effectively prevent the simulation component 2 from sliding during the simulation training.

[0047] In a specific embodiment, such as Figure 5 , the detection component 5 includes a mounting block 51, a transmission rod 52, a detection block 53, a PCB board 54 and a mounting groove 55. The mounting block 51 is installed on the front side of the mounting clip 4, a mounting groove 55 is opened in the mounting block 51, the mounting groove 55 extends into the mounting space, the detection block 53 is installed in the mounting groove 55, the transmission rods 52 are arranged in pairs and installed at the front end of the detection block 53, the PCB board 54 is installed in the mounting groove 55, the PCB board 54 is installed at the front end of the detection block 53, and the PCB board 54 is in contact connection with the transmission rod 52. Through the design of the mounting groove 55, it is convenient for the insertion of the baffle 27. The detection block 53 and the detection piece 26 sense through contact, and transmit the occlusion signal of the baffle 27 to the PCB board 54 through the transmission rod 52. The PCB board 54 feeds back the occlusion signal to the user through the internal feedback module such as a buzzer.

[0048] In a specific embodiment, the simulation component 2 is made of a soft and elastic material. The simulation component 2 will be made of silicone material. Using this material, it is soft, elastic, vivid, has a strong anti-tearing degree, one part can withstand multiple punctures, and the reusability is higher.

[0049] In a specific embodiment, such as Figure 6 , the connecting piece 6 includes a mounting hole 61 and a connecting pipe 62. The right end of the connecting pipe 62 is inserted into the thyroid cartilage 1, and the mounting holes 61 are arranged in pairs and opened on the side wall of the connecting pipe 62. The setting of the mounting holes 61 is to facilitate the connection of the mask.

[0050] Although the present utility model has been described in detail above with general descriptions and specific embodiments, on the basis of the present utility model, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model all fall within the scope of protection required by the present utility model.
