Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical devices, in particular to a mold circuit flip cover mechanism integrated with an electronic APL valve and an anesthesia machine. BACKGROUND

[0002] The APL valve (adjustable pressure release valve) commonly used in the market is mainly of mechanical structure. The mechanical APL valve is usually installed on the anesthesia circuit through a threaded structure, and a circuit cover plate is provided at the upper part as a decorative part. The existing circuit cover plate is generally installed in a flat push-pull type. When high-temperature sterilization and disinfection of the circuit is required, the operator needs to first remove the circuit cover plate, then unscrew the mechanical APL valve, and finally remove the circuit for disinfection. This process is complicated and inconvenient to operate, especially when the clinical workload is heavy or the equipment needs to be switched urgently, which significantly increases the workload.

[0003] Although the mechanical APL valve structure is relatively simple and reliable, it has the following obvious deficiencies in actual application:

[0004] Installation and disassembly are complicated: the cover plate needs to be removed first, and then the valve body needs to be screwed, which takes a long time, and frequent disassembly and assembly can cause thread wear, reducing the service life of the circuit.

[0005] Low control accuracy and response speed: the mechanical APL valve relies on a manual knob for adjustment, which has poor airway pressure adjustment accuracy and slow response, which is not conducive to accurate control of the patient's airway pressure.

[0006] Data cannot be traced: the mechanical APL valve does not have electronic recording function, and clinical data is difficult to save and trace, which cannot meet the data management needs of modern anesthesia machines.

[0007] Compared with the mechanical APL valve, the electronic APL valve has the advantages of high control accuracy, fast response, and traceable data, but it controls the airway pressure through electronic circuits such as stepper motors and potentiometers, and integrates multiple electronic components, which cannot withstand high-temperature sterilization. In the existing structure, the electronic APL valve is integrally connected with the circuit, and when the circuit is subjected to high-temperature sterilization and disinfection, the electronic APL valve must be completely removed, which is prone to omission or non-standard operation. If a component containing electronic components is mistakenly placed in the disinfection equipment, the key components are likely to be damaged, causing economic losses and the risk of equipment downtime.

[0033] The application will be further described in detail below in combination with the drawings and specific embodiments.

[0034] Embodiment 1

[0035] As shown in FIGS. 1 to Figure 6 The integrated electronic APL valve mold circuit flip mechanism disclosed in the embodiment mainly consists of a circuit flip shell 1, a flip cover plate 5, a flip assembly 3, an electronic APL valve 6, a circuit board isolation structure, a flip lock 12 and related auxiliary components. The components cooperate to realize reliable installation of the electronic APL valve 6, convenient flip operation of the circuit and effective isolation of the electrical elements and the circuit.

[0036] 1. Circuit flip shell and related components (FIGS. 1(a), 1(b))

[0037] The circuit flip shell, as the basic bearing structure of the entire device, is assembled by screwing the circuit flip shell 1 and the flip cover plate 5 to provide an installation carrier for the components. Two transparent windows 4 are installed on the circuit flip shell 1, and the flip cover plate 5 forms a groove extending to the shell at the positions corresponding to the transparent windows 4, with a hollow area inside the groove. On the one hand, the groove is used to press the transparent windows 4, making the transparent windows 4 more stable during installation and not blocking the visual range of the transparent windows 4; on the other hand, the hollow area in the groove can reduce the overall structure weight.

[0038] The transparent windows 4 are installed on the circuit flip shell 1 and fixed by pressing with the flip cover plate 5. The operator can directly observe the action of the flap piece when inhaling and exhaling through the transparent windows 4, and real-time master the working state of the circuit. The flip cover plate 5 is used to press the transparent windows 4 to ensure that the installation of the transparent windows 4 on the circuit flip shell 1 is firm and prevent the transparent windows 4 from loosening during device operation or flipping.

[0039] 2. Electronic APL valve and installation structure (FIGS. 1, Figure 2 )

[0040] The electronic APL valve 6 is installed on the APL valve seat 11, and its power supply circuit and control circuit are connected to the circuit board 8 and realize signal transmission with the main board of the anesthesia machine. The operating end of the electronic APL valve 6 extends out of the circuit flip shell 1, and the shaft end (screw guide) extends out of the flip cover plate 5, facilitating external operation. A stepping motor for the electronic APL valve 6 is also installed inside the circuit flip shell 1 to provide precise adjustment function.

[0041] The APL valve seat 11 is fixed inside the circuit flip shell 1 by screws and is used to bear the electronic APL valve 6, providing a stable installation basis for the electronic APL valve 6 and ensuring the position of the electronic APL valve 6 stable during device operation.

[0042] 3. Circuit board isolation structure (Figure 2 )

[0043] The circuit board 8 is connected with the power supply line and control line of the electronic APL valve 6, used for receiving and processing electrical signals, and connected with the main board of the anesthesia machine through the connecting line to realize signal transmission. The circuit board 8 is assembled in the circuit board isolation shell 9 made of non-metallic material, located in the groove of the circuit flip cover shell 1, which can effectively isolate the circuit board 8 from the circuit flip cover shell 1, avoid static damage to the circuit board 8, and ensure the normal work of electronic components.

[0044] 4. The flip assembly 3 and the rack 2 Figure 2 、 Figure 4 )

[0045] The rack 2 is the fixed base of the device, connected with the circuit flip cover shell 1 through the flip assembly 3, providing support for the entire circuit flip cover mechanism.

[0046] The flip assembly 3 includes a flip cover connecting block 18, a first rotating shaft 14, a first torsional spring 15, a bump stop pad 17 and a second wire pressing plate 16.

[0047] The flip cover connecting block 18 adopts a V-shaped structure, connected with the rack 2 through the first rotating shaft 14, so that the circuit flip cover shell can be flipped by 90°, saving installation space. The flip cover connecting block 18 is provided with a groove 19 for hiding the lines connected with the electronic APL valve 6 and the circuit board 8, and fixed through the second wire pressing plate 16, so that the line layout is neat and beautiful.

[0048] The first rotating shaft 14 provides a rotating shaft for the flip cover connecting block 18, which can be smoothly flipped on the rotating shaft. The first torsional spring 15 is installed on the first rotating shaft 14, which can support the flip cover when the circuit flip cover shell is opened, preventing the flip cover from freely rotating due to gravity and affecting the disassembly and assembly operation of the circuit.

[0049] The bump stop pad 17 is installed at the contact part of the flip cover connecting block 18 and the rack 2, which can buffer the impact between the two when the circuit flip cover shell is opened, effectively reducing noise.

[0050] The second wire pressing plate 16 presses the lines of the electronic APL valve 6 and the circuit board 8 in the groove 19 of the flip cover connecting block 18, realizing line fixation and hiding, and making the overall structure neat and beautiful.

[0051] 5. The structure of the flip cover lock 12 Figure 2 、 Figure 5 、 Figure 6 )

[0052] The flip cover lock 12 is used to lock and unlock the circuit flip cover mechanism and the circuit cover 25, and mainly comprises a base 22, a second rotating shaft 20, a button 23, a limiting block 21 and a second torsion spring 24.

[0053] The base 22 is installed on the circuit flip cover 1, and provides a mounting basis for other components of the flip cover lock 12, and ensures that the relative positions of the components are fixed.

[0054] The second rotating shaft 20 passes through the limiting holes of the base 22 at both ends, and is connected with the button 23 at one end and the limiting block 21 at the other end. The second rotating shaft 20 is provided with a D-shaped shaft structure at both ends, which is matched with the D-shaped holes on the button 23 and the limiting block 21, so as to ensure that the button 23, the second rotating shaft 20 and the limiting block 21 rotate synchronously and reliably transmit the torque.

[0055] The limiting block 21 is installed on the second rotating shaft 20 and rotates synchronously with the button 23 and the second rotating shaft 20, and is provided with a hole through which the arm of the second torsion spring 24 passes, so as to provide a support point for the second torsion spring 24.

[0056] The button 23 is installed at one end of the second rotating shaft 20. When the button 23 is pressed, the second rotating shaft 20 and the limiting block 21 are rotated, so that the second torsion spring 24 is deformed. When the button 23 is released, the elastic force of the second torsion spring 24 makes the button 23, the second rotating shaft 20 and the limiting block 21 reset. The hook on the button 23 is clamped into the groove of the circuit cover 25 in the locked state, so as to achieve locking. In the unlocked state, the hook is away from the groove.

[0057] One arm of the second torsion spring 24 is supported on the circuit flip cover 1, and the other arm passes through the hole in the limiting block 21, so as to provide an elastic force for the reset of the button 23, and ensure that the locking and unlocking actions are reliably achieved.

[0058] The circuit cover 25 is matched with the circuit flip cover 1, and is provided with a groove which is matched with the hook on the button 23, so as to achieve locking of the circuit flip cover.

[0059] 6. Proximity sensor and wire pressing structure Figure 2 , Fig. 3(a), Fig. 3(b)

[0060] The proximity sensor 13 is installed on the circuit flip cover 1, and its line is first connected to the circuit board 8, and then connected to the main board of the anesthesia machine through the connecting wire. As shown in Fig. 3(a), when the circuit flip cover mechanism is in the closed state, the magnet on the proximity sensor 13 senses the metal element of the circuit cover 25, outputs an electrical signal and transmits it to the circuit board 8, and then transmits it to the main board of the anesthesia machine by the circuit board 8, prompting that the circuit flip cover mechanism has been closed in place.

[0061] As shown in Figure 3(b), when the circuit flip-top mechanism is in the open state, the proximity sensor 13 cannot sense the circuit housing 25, outputs a corresponding electrical signal and transmits it to the anesthesia machine main board via the circuit board 8, indicating that the circuit flip-top mechanism has been opened.

[0062] The first pressure plate 10 is located inside the loop cover housing 1 (two are provided in this embodiment) and is used to organize and fix the internal wiring to prevent messy wiring from affecting the operation of the device and to ensure that the wiring layout is neat and orderly.

[0063] The second pressure plate 16 is used to press the lines of the electronic APL valve 6 and the circuit board 8 into the groove 19 of the flip-top connecting block 18, so as to hide and stabilize the lines.

[0064] As can be seen from the above detailed description of the present invention, the modular circuit flip-top mechanism for the integrated electronic APL valve provided in this embodiment has at least the following technical effects:

[0065] This invention integrates the electronic APL valve 6, the flip cover plate 5, the circuit flip cover shell 1, the flip assembly 3, and the flip lock 12, making the overall structure of the device compact, occupying little space, and making installation and maintenance more convenient.

[0066] The combination of APL valve seat 11 and electronic APL valve 6 ensures reliable installation of electronic APL valve 6 in the circuit, avoids damage to electronic components due to high-temperature sterilization along with the circuit housing 25, and improves product durability.

[0067] Setting up a transparent window 4 allows operators to visually observe the movement of the valve plates within the circuit, facilitating real-time assessment of the circuit's operating status and enhancing operational visibility and safety.

[0068] The flip assembly 3 allows the circuit flip cover 1 to flip up to a large angle of 90°, facilitating the disassembly and assembly of the circuit, and prevents the flip cover from rotating freely through the first torsion spring 15. The flip cover connecting block 18, the groove 19, and the second wire pressing plate 16 can hide the wiring, making the appearance neat and beautiful.

[0069] The flip lock 12 has a reasonable structural design. The button 23 is locked in place with the groove of the circuit housing 25, and the unlocking and resetting actions are reliable, ensuring the safety of the flip.

[0070] The proximity sensor 13 can detect the opening and closing status of the flip cover in real time and transmit the signal to the main board of the anesthesia machine, which enhances the safety and prompting function of the equipment operation.

[0071] The anti-collision pad 17 cushions the impact when the flip cover is opened, reducing noise and improving the user experience.
