Description

Technical Field

[0001] This utility model belongs to the field of medical facility technology, and in particular relates to a desktop locking device for a ventilator. Background Technology

[0002] Ventilators are commonly used equipment in healthcare settings. As an effective means of artificially replacing spontaneous ventilation, they are widely used for respiratory failure caused by various reasons, anesthetic respiratory management during major surgery, respiratory support therapy, and emergency resuscitation, occupying a very important position in the field of modern medicine. Ventilators are crucial medical devices that can prevent and treat respiratory failure, reduce complications, and save and prolong patients' lives. Currently, ventilators are simply placed on a table during use. Due to the long cables and tubing, they are prone to displacement and instability during use due to accidental pulling of the cables and tubing, and may even fall from the table to the ground, causing damage to the equipment. Furthermore, the vibrations generated by the ventilator during operation can also cause it to gradually shift on the table, ultimately leading to the aforementioned instability or even falling problems.

[0003] In summary, a locking device needs to be developed and designed to solve the aforementioned technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a desktop locking device for a ventilator, which provides a reliable locking function for the ventilator and avoids instability caused by the ventilator's own operating vibration and the tension on cables and tubing.

[0005] The technical solution adopted by this utility model is as follows: a desktop locking device for a ventilator, including a desktop panel with two panel windows on the left and right sides. A bracket is installed in the lower middle part of the desktop panel, and locking components are installed at the left and right ends of the bracket. The locking components include a housing, a support base is fixedly installed on the side of the housing, an upper connecting arm is installed on the top of the housing via a pivot, a lower connecting arm is installed on the support base via a pivot, and a base is also included. The upper ends of the upper and lower connecting arms are each connected to the base via pivots. A clamping plate is hinged on the base, and a rubber pad is installed on the clamping plate. The clamping plate is located inside the panel windows. A drive mechanism is also installed on the housing to drive the upper connecting arm to deflect outward or inward.

[0006] Preferably, the drive mechanism includes a driving gear and a driven gear installed inside the housing, which mesh and drive each other. The driven gear is installed on the shaft at the lower end of the upper connecting arm. A worm gear is provided on the side of the driving gear, and a worm is also included. The worm gear and the worm form a worm gear mechanism. A crank is also installed at the end of the worm.

[0007] Preferably, a limit stop is installed on the side of the base, and when the clamping plate rotates to the upright position, its bottom contacts the limit stop.

[0008] Preferably, the rubber pad is fixed in the middle of the clamping plate, and a through finger hole is provided at the end of the clamping plate.

[0009] Preferably, the bracket includes a top plate and a bottom plate, with a connecting plate between the top plate and the bottom plate. The top plate is fixedly connected to the tabletop plate with screws. Bending plates are provided at both ends of the bottom plate. An adapter is installed on the side of the outer shell, and the adapter is fixedly connected to the bending plate of the bottom plate with screws.

[0010] The advantages and positive effects of this utility model are:

[0011] This invention provides a desktop locking device for ventilators, used to lock the placed ventilator on the desktop. By providing a reliable locking function, it prevents instability caused by the ventilator's own vibrations and the tension on cables and tubing during use, thus avoiding equipment damage and interruption of use due to ventilator instability or drops. This desktop locking device has two panel windows on the left and right sides of the desktop panel, and two locking components are installed on the left and right sides below the desktop panel. By rotating the clamping plates and their rubber pads to an upright position and operating the drive mechanism to cause the four-bar structure consisting of the upper connecting arm, lower connecting arm, base, outer shell, and support seat to deflect and swing inward, the left and right clamping plates and their rubber pads can clamp and lock the ventilator in the center. The locking effect is stable, and the rubber pads prevent damage to the ventilator shell.

[0012] When not in use, the aforementioned four-bar linkage can be operated to swing outward and rotate the clamping plate and its rubber pad to a tilted position. After tilting, the clamping plate and its rubber pad fall completely into the panel window, thus keeping the surface of the desktop flat and not affecting the placement of items on the desktop.

[0018] To further understand the invention content, features and effects of this utility model, the following embodiments are provided in detail.

[0019] Please see Figure 1 The present invention relates to a desktop locking device for a ventilator, comprising a desktop panel 1, with two panel windows 2 on the left and right sides of the desktop panel 1, and a bracket 3 installed in the lower center of the desktop panel 1. Locking components are installed at the left and right ends of the bracket 3. In actual use, the desktop panel 1 can be installed and fixed on the top of a cabinet to form a desktop such as that of a bedside table in a ward.

[0020] The locking component can switch between two postures: in the non-use posture, the locking part falls into the panel window 2, at which time the surface of the desktop 1 is flat, thus not affecting the placement of objects on the desktop 1; in the use posture (referring to...), the locking part falls into the panel window 2, and .... Figure 1 As shown in the diagram, the locking component extends from the panel window 2 and the two locking components move towards each other, clamping and fixing the ventilator 4 in the middle, thus locking the ventilator 4 and preventing instability caused by the ventilator 4 due to its own operating vibration and the pulling of cables and tubing.

[0021] Please see Figure 2 and Figure 3 It can be seen that:

[0022] The locking assembly includes a housing 11, with a support base 10 fixedly mounted on the side of the housing 11. The support base 10 is fixedly connected to the side of the housing 11 by screws. An upper connecting arm 12 is mounted on the top of the housing 11 via a pivot, and a lower connecting arm 9 is mounted on the support base 10 via a pivot. The assembly also includes a base 8. The upper ends of both the upper connecting arm 12 and the lower connecting arm 9 are connected to the base 8 via pivots. Specifically, the upper end of the upper connecting arm 12 is connected to the inner side of the base 8 via a pivot, and the upper end of the lower connecting arm 9 is connected to the outer side of the base 8 via a pivot. Therefore, the upper connecting arm 12, the lower connecting arm 9, the base 8, the support base 10, and the housing 11 constitute a four-bar linkage structure.

[0023] A clamping plate 5 is hinged to the base 8, and a rubber pad 6 is mounted on the clamping plate 5. The clamping plate 5 is located inside the panel window 2. A drive mechanism is also installed on the outer casing 11 to drive the upper connecting arm 12 to deflect outward or inward. The drive mechanism can operate the aforementioned four-bar linkage to change shape, thereby causing the clamping plate 5 and its rubber pad 6 to move inward or outward. Figure 1 The image shows the locking posture of the ventilator 4. It can be seen that at this time, the left and right clamping plates 5 and their rubber pads 6 are respectively clamped on both sides of the ventilator 4, producing a locking effect. The rubber pads 6 have a certain degree of flexibility, so they will not cause damage to the shell of the ventilator 4. At the same time, the rubber pads 6 can also provide the friction required for locking, making the locking effect of the ventilator 4 more stable.

[0024] In this embodiment, the drive mechanism includes a driving gear 17 and a driven gear 15 installed inside the housing 11, which mesh and drive each other. The driven gear 15 is mounted on the shaft at the lower end of the upper connecting arm 12. A worm gear 16 is provided on the side of the driving gear 17, and a worm 18 is also included. The worm gear 16 and the worm 18 form a worm gear mechanism. A crank 14 is also installed at the end of the worm 18. The crank 14 can be used to manually operate the worm 18 to rotate forward or in reverse. The worm 18 drives the worm gear 16 to rotate forward or in reverse, and the driving gear 17 rotates forward or in reverse accordingly. The driven gear 15 drives the shaft at the lower end of the upper connecting arm 12 to rotate forward or in reverse accordingly. As a result, the upper connecting arm 12 swings inward or outward, and the aforementioned four-bar linkage changes shape accordingly.

[0025] According to the characteristics of the four-bar linkage, when the four-bar linkage changes shape, the clamping plate 5 and its rubber pad 6, which are in the upright position, move inward or outward, but their upright position does not change.

[0026] In this embodiment, a limiting block 7 is installed on the side of the base 8. When the clamping plate 5 rotates to the upright position, its bottom contacts the limiting block 7. The limiting block 7 is used to limit the upright position of the clamping plate 5. When the clamping plate 5 is turned from the tilted position to the upright position, the clamping plate 5 rotates around the hinge axis between itself and the base 8. When the bottom of the clamping plate 5 contacts the limiting block 7, the clamping plate 5 changes to the final upright position. In the final upright position, the clamping plate 5 is perpendicular to the horizontal plane. In this way, the left and right sets of clamping plates 5 and their rubber pads 6 can provide a more stable clamping and locking effect on the ventilator 4.

[0027] In this embodiment, the rubber pad 6 is fixedly installed in the middle of the clamping plate 5, and a through finger hole 19 is provided at the end of the clamping plate 5. The purpose of providing the finger hole 19 is to improve the convenience of rotating the clamping plate 5 and its rubber pad 6. When the clamping plate 5 is in a tilted position and falls into the panel window 2, it is necessary to rotate the clamping plate 5 from the tilted position to... Figure 1 When in the upright position shown, fingers can be passed through the finger hole 19, and then the clamping plate 5 can be hooked out from the panel window 2.

[0028] In this embodiment, the bracket 3 includes a top plate and a bottom plate, with a connecting plate between the top plate and the bottom plate. The top plate is fixedly connected to the desktop plate 1 with screws. Bending plates are provided at both ends of the bottom plate. An adapter 13 is installed on the side of the outer shell 11. The adapter 13 is fixedly connected to the side of the outer shell 11 with screws. The adapter 13 is fixedly connected to the bending plate of the bottom plate with screws.

[0029] How to use:

[0030] When not in use, the clamping plate 5 and its rubber pad 6 are turned to a tilted position and fall into the panel window 2. At this time, the surface of the desktop 1 is flat and does not affect the placement of items on the desktop 1.

[0031] When it is necessary to clamp and lock the ventilator 4, the operator inserts their fingers into the finger holes 19 at the end of the clamping plate 5, and then hooks the clamping plate 5 and its rubber pad 6 out from the panel window 2. The clamping plate 5 is gradually turned into an upright position until the bottom of the clamping plate 5 contacts the limiting block 7 to reach the final upright position. Then, the ventilator 4 is placed on the tabletop 1, between the left and right clamping plates 5 and their rubber pads 6. Then, the cranks 14 of the left and right locking components are operated from below. The four-bar structure of the locking components changes shape, and the left and right clamping plates 5 and their rubber pads 6 move toward the ventilator 4. Finally, the rubber pads 6 press against the shell of the ventilator 4. At this time, the left and right clamping plates 5 and their rubber pads 6 clamp and lock the ventilator 4 to prevent instability.

[0032] When it is necessary to unlock the ventilator 4, operate the cranks 14 of the left and right locking components to change the shape of the four-bar structure of the locking components. The left and right clamping plates 5 and their rubber pads 6 move away from the ventilator 4, releasing the clamping and locking effect on the ventilator 4. Then the ventilator 4 can be removed. After that, operate the clamping plates 5 and their rubber pads 6 to change from an upright position to a tilted position. Finally, the clamping plates 5 and their rubber pads 6 fall into the panel window 2, and the surface of the desktop 1 returns to flat. Of course, as mentioned above, this desktop locking device can usually be applied to such as a bedside table in a ward. In this case, the locking components are located inside the cabinet, and the cabinet door needs to be opened to perform the aforementioned operation.
