Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a protective device for a pushable anesthesia machine. Background Art

[0002] Because pushable anesthesia machines are frequently moved between different medical settings, such as operating rooms and emergency rooms, their internal electronic components are extremely susceptible to collisions and impacts during transportation and use. Since electronic components are sensitive to vibration and shock, damage can not only affect the anesthesia machine's monitoring accuracy and functional stability, but can also cause equipment failure, endangering the patient's life. Currently, most push-type anesthesia machines utilize traditional medical rubber protective shells as their protective structure. While rubber has a certain degree of shock absorption and can mitigate the impact of minor collisions, its energy absorption capacity is limited in the face of more severe collisions or high-energy impacts, making it difficult to meet the increasingly stringent safety protection requirements in clinical environments. Summary of the Invention

[0027] The following is combined with Figure 1-6 The present invention is described in further detail.

[0028] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0029] See also Figure 1-6 As shown, a protective device for a pushable anesthesia machine is shown, including a steel base 1. The steel base 1 has a high structural strength and can effectively protect the anesthesia machine components. The base 1 includes a base body 11 and a cover plate 12 provided on the base body 11. An inner cavity 2 for accommodating the anesthesia machine components is formed between the base body 11 and the cover plate 12. A connecting plate 13 is also provided on one side of the base body 11 in the width direction. The connecting plate 13 is relatively fitted with one side of the cover plate 12 and the two are connected by bolts. The cross section of the base body 11 is rectangular, and four universal wheels 6 for movement are provided at the bottom.

[0030] In this embodiment, combined with Figure 3 As shown, the protection device further includes a limiting portion 3 provided in the inner cavity 2 , the limiting portion 3 having a limiting surface 31 abutting against the anesthesia machine components, and a shock absorbing component 4 is further provided between the limiting portion 3 and the cavity wall of the inner cavity 2 .

[0031] Specifically, the limiting portion 3 includes two symmetrical limiting plates 32 corresponding to the longitudinal walls of the inner cavity 2. The two limiting plates 32 are parallel to each other and extend along the width of the inner cavity 2. The two ends of each limiting plate 32 are connected to the two width walls of the inner cavity 2. A limiting cavity 33 for accommodating anesthesia machine components is formed between the two limiting plates 32. Two damping assemblies 4 are respectively disposed between the two limiting plates 32 and the corresponding cavity walls.

[0032] In this way, the two limiting plates 32 can respectively abut against the two sides of the anesthesia machine components through their respective limiting surfaces 31, effectively avoiding the displacement of the anesthesia machine components when the base 1 faces collision or impact, and improving the position stability of the anesthesia machine components; at the same time, the shock-absorbing components 4 on both sides can cushion the anesthesia machine components from both sides, with good shock-absorbing effect, which can prevent the anesthesia machine components from being damaged.

[0033] In this embodiment, the damping assembly 4 includes a damping groove 41 formed between the limiting plate 32 and a side wall of the inner cavity 2 along its length, and a damping medium (not shown) contained within the damping groove 41. The length of the damping groove 41 aligns with the length of the limiting plate 32, and the damping medium is silicone oil. Silicone oil has a high viscosity and can convert vibration energy from anesthesia machine components into heat energy through friction between its molecules, thereby reducing the vibration amplitude of the anesthesia machine components.

[0034] In this embodiment, combined with Figure 4 As shown, the upper cover of the shock absorbing groove 41 is provided with a groove plate 42, and the side of the groove plate 42 facing the shock absorbing groove 41 is provided with a compensation part 43, and the compensation part 43 is deformable. Among them, the compensation part 43 is an air spring. During the shock absorbing process of the silicone oil, its volume will change to a certain extent. The air spring can compensate for the volume of the silicone oil through its own deformation to ensure that the silicone oil can continue to have an excellent shock absorbing effect. When the silicone oil expands due to heat, the air spring will be compressed to absorb the excess volume; when the silicone oil cools and shrinks or there is a small amount of loss, the air spring will expand to replenish the volume of the silicone oil to maintain the normal working state of the shock absorbing component 4.

[0035] The circumferential side of the slot plate 42 is bolted to the circumferential side of the damping slot 41, with a sealing ring (not shown) positioned between the two. If the silicone oil in the damping slot 41 is significantly depleted, the slot plate 42 can be manually removed and silicone oil added to the damping slot 41.

[0036] In this embodiment, again combined Figure 3 As shown, six first baffles 44 are spaced apart along the length of the shock absorbing groove 41. A first groove body 411 is formed between each two adjacent first baffles 44. Each first groove body 411 contains a damping medium. The damping medium in the five first groove bodies 411 can provide overall shock absorption for the anesthesia machine components along the length of the limit plate 32, effectively improving the uniformity of shock absorption.

[0037] The first partition plate 44 includes a damping hole 47, the diameter of which gradually decreases along the direction from the seat body 11 to the connecting plate 13. The damping holes 47 on the first partition plate 44 enable the damping medium to flow throughout the plurality of first slots 411, effectively improving the damping medium's uniformity. Furthermore, the damping holes 47 reduce the flow rate and flow velocity of the damping medium, thereby enhancing its damping effect.

[0038] In this embodiment, a second slot 412 is formed between the first of the six first baffles 44 and one sidewall of the seat body 11 in the width direction, and between the last of the six first baffles 44 and the other sidewall of the seat body 11 in the width direction. Two compensating portions 43 are provided, each housed in the two second slots 412. When the damping medium expands due to heat, it can flow through the multiple damping holes 47 into the two second slots 412, compressing the air spring and absorbing the excess volume. When the damping medium cools and contracts or experiences a small amount of loss, the air spring expands, pushing the damping medium in the two second slots 412 into the first slot 411 to replenish the overall volume of the damping medium.

[0039] In this embodiment, each first trough 411 is provided with three second baffles 46 that are parallel to each other and extend in a curved manner along the direction from the limiting plate 32 to the cavity wall. The second baffles 46 are S-shaped, with one end of the second baffle 46 connected to the limiting plate 32 and the other end having a gap 49 between the cavity wall of the inner cavity 2. Two interconnected S-shaped first damping channels 45 are formed between the three second baffles 46. When the base 1 encounters a collision or impact, the damping medium can flow along the S-shaped first damping channels 45, effectively increasing the flow resistance of the damping medium and enhancing the damping medium's absorption effect on vibration energy. The interconnection of the two first damping channels 45 enables the damping medium to flow as a whole within the first trough 411, effectively improving the damping effect of the damping medium.

[0040] Two second damping channels 48 are formed between each pair of adjacent first baffles 44 and the two first damping channels 45. One sidewall of the second damping channel 48 is an S-shaped second baffle 46, and the other sidewall is a first baffle 44. The second damping channel 48 can cooperate with the first damping channel 45 to achieve damping of the anesthesia machine components by the damping medium.

[0041] In this embodiment, four buffer columns 5 are further provided on one side of each limiting plate 32 facing the anesthesia machine components. The four buffer columns 5 are each deformable. The deformable buffer columns 5 can abut against the anesthesia machine components and further cushion the anesthesia machine components through their own deformation, thereby further preventing damage to the anesthesia machine components.

[0042] Specific, combined Figure 3and Figure 6 As shown, the buffer column 5 extends along the depth direction of the buffer groove and includes a first column 51 and a second column 52 arranged opposite each other. The first column 51 is embedded in the limit plate 32. A slot 53 extending along its length is provided on one side of the first column 51 facing the second column 52. Three elastic members 54 are provided in the slot 53 along its length. The elastic members 54 are springs. A slide bar 55 extending along its length is provided on one side of the second column 52 facing the first column 51. The slide bar 55 is inserted into the slot 53 and connected to the three elastic members 54. The first column 51 and the second column 52 can move closer or farther away from each other under the action of the elastic members 54 to achieve buffering of the anesthesia machine components.

[0043] The implementation principle of the protection device in the embodiment of the present application is: When the base 1 is subjected to a severe collision or impact, the limiting plates 32 on both sides press against the anesthesia machine components through their respective limiting surfaces 31, the first column 51 and the second column 52 are relatively close to each other and the elastic force of the elastic member 54 is used to cushion the anesthesia machine components. The damping medium in the shock-absorbing groove 41 flows along the first damping channel 45 and the second damping channel 48 during the collision. During the flow, the damping medium gradually absorbs the vibration energy.

[0044] The embodiments of this specific implementation method are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
