Description

Technical Field

[0001] This application belongs to the field of medical device technology, and in particular relates to a press-type ejection mechanism and an anesthesia machine. Background Technology

[0002] The coil is a component of the anesthesia machine circuit, used to store the patient's inhaled or exhaled gases. It has a total capacity of approximately 1500 ml, and its internal structure resembles a coiled tube, hence the name "coil." The main body of the coil, after removing the sealing cap, looks like... Figure 1 As shown.

[0003] In existing anesthesia machines, the coil is stored inside the machine body. When disassembly is needed, the storage casing must be pried open by hand to pull the coil out. Because the stress-bearing parts of the storage casing are tightly fitted to the adjacent parts of the anesthesia machine casing, it is inconvenient to apply force. Furthermore, the exposed part of the coil needs to be smooth with the surrounding surface to prevent injury to the user during use. This makes it quite difficult to pull the coil directly out of the anesthesia machine by hand. Utility Model Content

[0004] The purpose of this application is to overcome the defects of the prior art and propose a push-type pop-out mechanism, including: a gas spring 1, a semi-enclosed cavity 2 with an open front end, and a mounting base 3;

[0005] The gas spring 1 is fixedly mounted on the mounting base 3;

[0006] The mounting base 3 is fixed to the outer wall of the rear panel of the semi-enclosed cavity 2; the rear panel of the semi-enclosed cavity 2 has a through hole that allows the piston rod to pass through relative to the position of the piston rod of the gas spring 1.

[0007] The interior of the semi-enclosed cavity 2 is used to house the device 4;

[0008] When the gas spring 1 is in the retracted state, its piston rod contacts the device 4 through the through hole in the rear panel of the semi-enclosed cavity 2; when the device 4 is pressed inward at the front end of the semi-enclosed cavity 2, the piston rod pops the device 4 out by a set stroke, so that the gas spring 1 changes from the retracted state to the open state.

[0009] As an improvement to the aforementioned pop-out mechanism, it also includes: handle box 5;

[0010] The handle box 5 includes a front panel, a rear panel, and two side panels that are assembled together to form a groove 6;

[0011] The overall dimensions of the rear panel of the handle box 5 are matched with the dimensions of the front panel of the device 4, and the handle box 5 is fixed to the front panel of the device 4 through its rear panel;

[0012] When the gas spring 1 is in the retracted state, the groove 6 of the handle box 5 and the device 4 are hidden in the semi-enclosed cavity 2; by pressing the handle box 5 inward, under the action of the gas spring 1, the device 4 pops the handle box 5 outward, exposing the groove 6.

[0013] As an improvement to the above-mentioned ejection mechanism, it also includes a limiting structure 7 disposed on the side panel of the semi-enclosed cavity 2, and a limiting accessory that cooperates with the limiting structure 7 is provided at a corresponding position on the surface of the device 4.

[0014] As an improvement to the aforementioned pop-out mechanism, the limiting structure 7 includes: a rivet 71, a steel ball 72, and a spring piece 73;

[0015] The rivet 71 is used to fix the spring piece 73 to the outer wall of the side panel of the semi-enclosed cavity 2;

[0016] The steel ball 72 is disposed between the spring piece 73 and the outer wall of the semi-enclosed cavity 2; the outer wall of the semi-enclosed cavity 2 has a circular through hole with a diameter smaller than that of the steel ball 72 at a position opposite to the steel ball 72, and the steel ball 72 protrudes through the circular through hole to the inner wall of the semi-enclosed cavity 2 by a certain size;

[0017] The limiting accessory is a recess 8 located on the outer side wall of the device 4 for engaging with the steel ball 72.

[0018] As an improvement to the aforementioned ejection mechanism, the spring 73 is made of 0Cr18Ni9 material and has a thickness of 0.5mm.

[0019] As an improvement to the aforementioned ejection mechanism, the bottom plate of the semi-enclosed cavity 2 is provided with a triangular rib 9, or the bottom of the device 4 is provided with a triangular rib 9.

[0020] As an improvement to the aforementioned pop-up mechanism, a platform is also included;

[0021] The platform is fixed to the rear panel of the device 4, and the gas spring 1 pushes the device 4 out by applying elastic force to the platform.

[0022] As an improvement to the above-mentioned ejection mechanism, the gap between the inner wall of the side of the semi-enclosed cavity 2 and the outer wall of the side of the device 4 is greater than or equal to 1.5 mm.

[0023] As an improvement to the aforementioned pop-out mechanism, the side panel of the device 4 has at least one external connection window 10.

[0024] The side wall of the semi-enclosed cavity 2 has a window of the same size corresponding to the external connection window 10 of the device 4.

[0025] This application also provides an anesthesia machine, including the above-mentioned push-to-release mechanism, wherein the device 4 is a coil.

[0026] Compared with existing technologies, the advantages of this application are:

[0027] 1. The press-and-pop mechanism enables a device, such as a coil, to be popped out by pressing once. This is similar to opening a drawer, making it easier to pull the coil out by hand.

[0028] 2. A handle box connected to the equipment is provided. The groove in the handle box can be used to pull out pullable objects such as wires or pipes from the equipment, which is convenient for manual operation and aesthetically pleasing. The equipment can also be pulled out by hand like pulling out a drawer.

[0029] 3. A limiting structure is set up so that when the device is pressed again, it can be hidden and limited to a suitable position in the semi-enclosed cavity. This second press allows the gas spring to change from the open state to the retracted state, and the limiting structure also allows the gas spring to remain in the retracted state.

[0030] 4. Ribs are provided on the lower panel of the equipment or the lower panel of the semi-enclosed cavity, so that the lower panel of the equipment and the lower panel of the semi-enclosed cavity form a point connection, which reduces the friction caused by the large-area contact between the lower panel of the equipment and the lower panel of the semi-enclosed cavity.

[0058] The technical solution of this application will be described in detail below with reference to the accompanying drawings and embodiments.

[0059] like Figure 2 As shown, this application provides a push-to-pop mechanism, including: a gas spring 1, a cuboid semi-enclosed cavity 2 with an open front end, and a mounting base 3;

[0060] Mounting base 3 is disposed on the outer wall of the rear panel of the semi-enclosed cavity 2, and has a second mounting hole 32, such as Figure 3 As shown;

[0061] The rear panel of the semi-enclosed cavity 2 has a through hole that corresponds to the position of the piston rod of the gas spring 1, allowing the piston rod to pass through.

[0062] like Figure 4 As shown, the gas spring 1 extends to both sides from the middle to form a fixing plate for fixing to the mounting base 3, and the fixing plate has a first mounting hole 31 on both sides.

[0063] like Figure 5 As shown, when the gas spring 1 is installed on the mounting base 3, the first mounting hole 31 and the second mounting hole 32 coincide, which facilitates fixing with screws or rivets.

[0064] like Figure 6 As shown, the interior of the semi-enclosed cavity 2 is used to house the device 4.

[0065] The semi-enclosed cavity 2 can be made of sheet metal, which can ensure that the cables and screws inside the anesthesia machine can be covered after the device 4 is removed, thus serving to conceal the unsightly parts.

[0066] The gas spring 1 has a pop-out stroke of approximately 35mm on the first press, which is just the right distance for the device 4 to pop out and be held by hand. This gas spring 1 can be made from a standard part.

[0067] When the gas spring 1 is in the retracted state, its piston rod contacts the device 4 through the through hole in the rear panel. When the device 4 is pressed inward at the front end of the semi-enclosed cavity 2, the piston rod ejects the device 4 by a set stroke, causing the gas spring 1 to change from the retracted state to the extended state. At this time, the piston rod may contact the device 4, such as... Figure 7 As shown, it may also be detached from device 4. For example, suppose the piston rod can only extend 37mm, while the coil needs to extend 50mm; in this case, the piston rod is not in contact with device 4.

[0068] A preferred push-to-open mechanism also includes: a handle box 5, and such as Figure 8 As shown;

[0069] Handle box 5 includes a front panel, a rear panel, and two side panels that are assembled together to form a recess 6;

[0070] The overall dimensions and window dimensions of the rear panel of the handle box 5 are matched with the dimensions and window dimensions of the front panel of the device 4, respectively. The handle box 5 is fixed to the front panel of the device 4 through its rear panel.

[0071] The handle box 5 can be fixed to the front panel of the device 4 via its rear panel using a bayonet method. Figure 6 The front panel of the device has four buckles, and the rear panel of the handle box 5 has four matching buckles, which can be used to connect the handle box 5 and the device 4.

[0072] When the gas spring 1 is in the retracted state, the groove 6 of the handle box 5 and the device 4 are hidden in the semi-enclosed cavity 2. By pressing the handle box 5 inward, the device 4 will pop the handle box 5 outward under the action of the gas spring 1, exposing the groove 6.

[0073] At this point, you can easily apply force when you put your hand into the groove 6. When needed, you can pull the device 4 out further, just like pulling out a drawer.

[0074] Considering that the gas spring 1 is in the extended state after the device 4 pops out, in order to completely retract the device 4 into the semi-enclosed cavity 2 and change the spring from the extended state to the retracted state, the push-type pop-out mechanism preferably also includes a limiting structure 7 provided on the side panel or bottom panel of the semi-enclosed cavity 2, and a limiting accessory that cooperates with the limiting structure 7 is provided at the corresponding position on the surface of the device 4.

[0075] When the device 4 is pressed inward again through the limiting structure 7, the device 4 is limited within the limiting structure 7, thus realizing the process of hiding the device 4 in the semi-enclosed cavity 2 and changing the gas spring 1 from the open state to the retracted state.

[0076] The limiting structure 7 can be implemented in various ways. This application provides a specific implementation method, such as... Figure 9 As shown, the limiting structure 7 includes: rivet 71, steel ball 72 and spring piece 73.

[0077] Rivet 71 is used to fix the spring clip 73 to the outer wall of the side panel of the semi-enclosed cavity 2. The structure of rivet 71 and spring clip is as follows: Figure 10 As shown;

[0078] The steel ball 72 is disposed between the spring 73 and the outer wall of the side of the semi-enclosed cavity 2. The outer wall of the side of the semi-enclosed cavity 2 is provided with a through circular hole with a diameter smaller than that of the steel ball 72 at the location corresponding to the steel ball 72, so that the steel ball 72 protrudes from the inner wall of the side of the semi-enclosed cavity 2 by a set size.

[0079] The recess 8 located on the outer side wall of device 4 for engaging with steel ball 72, such as Figure 11 As shown.

[0080] It is important to note that the rivet 71 must not protrude in any part inside the semi-enclosed cavity 2, because the semi-enclosed cavity 2 is used to pull out the device 4, such as the coil, so it must be kept smooth and without any protrusions or obstructions.

[0081] In one embodiment, the steel ball 72 can protrude 2.5 mm beyond the inner wall of the semi-enclosed cavity 2, such as... Figure 12 As shown, the outer wall of the corresponding device 4 will have a pit 8, such as Figure 11 As shown. When device 4 reaches the appropriate position, steel ball 72 will engage with the recess 8 on the outer wall of device 4. The depth of recess 8 can be 1mm, such as... Figure 13 As shown.

[0082] The elastic force of the spring piece 73 is crucial; it must be less than the dynamic friction force generated when the device 4 is ejected and the elastic force of the gas spring 1. Therefore, the thickness of the spring piece 73 is also important. In one embodiment of this application, 0.4-0.6 mm is selected. An inappropriate thickness may result in a large elastic force of the spring piece 73, confining the device 4 within the limiting structure 7, which would prevent the force of the gas spring 1 from ejecting the device 4. Furthermore, the material of the spring piece 73 is also important. It can be a spring steel spring piece; preferably, in one embodiment of this application, 0Cr18Ni9 stainless steel is selected.

[0083] Preferably, the gap between the inner wall of the semi-enclosed cavity 2 and the outer wall of the device 4 is greater than or equal to 1.5mm to prevent the device 4 from getting stuck when the coil is pulled out. Figure 14 The case with a gap of 1.5mm is given. Preferably, the bottom plate of the semi-enclosed cavity 2 is provided with triangular ribs 9, or the bottom of the device 4 is provided with triangular ribs.

[0084] Figure 15 Two triangular ribs were designed at the bottom of device 4, such as the coil. These two ribs form a point connection with the bottom panel of the semi-enclosed cavity 2, which reduces the friction caused by large-area contact when there are no ribs.

[0085] Preferably, considering that the rear panel of the protective device 4 may not be flat, making it inconvenient for the piston rod of the gas spring 1 to apply elastic force to the device 4, the push-type pop-out mechanism also includes a platform; the platform is fixed to the rear panel of the device 4, and the gas spring 1 pushes the device 4 out by applying elastic force to the platform.

[0086] Considering that device 4 is usually connected to the outside, in order to enable device 4 to still be connected to the outside even when placed inside the semi-enclosed cavity 2, preferably, the side panel of device 4 has at least one external connection window 10; the semi-enclosed cavity 2 has a window that matches the external connection window 10 of device 4. Figure 6The document describes that when the device is a coil, the coil has two external connection windows 10: a driving gas inlet and an anesthetic gas inlet / outlet. Correspondingly, two connection windows are opened on the side of the semi-enclosed cavity 2.

[0087] For ease of observation, this application also provides a schematic diagram of the press-type pop-up mechanism after rendering the device 4, as shown in the embodiment. Figure 16 As shown; a schematic diagram of the press-type pop-up mechanism after rendering of the handle box 5 is also given, as follows. Figure 17 As shown. The push-to-pop mechanism with handle box 5 is a preferred embodiment of this application, which is convenient for pressing and further pulling out of the device 4, and is also more aesthetically pleasing.

[0088] This application embodiment also provides an anesthesia machine, in which device 4 is a coil and includes any of the above-mentioned push-to-pop mechanisms.

[0089] The push-to-release mechanism of this application allows the coil to be stored inside the anesthesia machine. When disassembly is needed, pressing the handle box activates a gas spring to eject the coil. To retract the coil, pressing the handle box again, with the assistance of a limiting structure, retracts the coil. Because the coil can be pulled out and retracted simply by pressing the handle box, the push-to-release mechanism of this application is convenient, easy to use, and aesthetically pleasing.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application do not depart from the spirit and scope of the technical solutions of this application, and should all be covered within the scope of the claims of this application.
