Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a main unit of a foaming device and a foaming device. Background Art

[0002] At present, when many hospitals and medical institutions conduct foaming tests, the preparation and injection of foaming liquid are both carried out manually. And during the preparation of the foaming liquid, an additional separate infusion stand is required for cooperation. When in use, the normal saline bottle is hung on the infusion stand, and then the infusion tube of the normal saline bottle is connected to the syringe pipeline used in the foaming test, so that the syringe can smoothly draw normal saline during the preparation and injection of the foaming liquid. However, since the infusion stand occupies additional indoor space, it is not conducive to the passage of medical staff. At the same time, when the equipment needs to be transferred after the preparation and injection of the foaming liquid are completed, the infusion stand and the equipment required for the foaming test need to be transferred separately, which is time-consuming and laborious.

[0012] Among them, the damping rotating shaft further includes an angle adjustment limiting structure. The angle adjustment limiting structure includes a limiting open ring fixedly or integrally connected to the surface of the second turntable facing the first turntable, and a limiting protrusion fixedly or integrally connected to the surface of the first turntable facing the second turntable; when the second turntable drives the limiting open ring to rotate to a preset angle, it is blocked by the limiting protrusion and cannot continue to rotate in the same direction.

Detailed implementation manners

[0028] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0029] The following will describe the implementation manners of the present utility model in detail with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0030] In the first aspect of the embodiment of the present utility model, a main body of a foaming device is provided. Referring to Figure 1 , the main body of the foaming device includes a main body housing 1 and a hanging bracket 2 for hanging an injection bottle (mainly referring to a physiological saline bottle, but can also be replaced with other medicine bottles according to needs); the non - hanging end of the hanging bracket 2 is rotationally mounted on the main body housing 1 through a rotating mechanism 3 and can be positioned at a suitable position when rotated relative to the main body housing 1 to a suitable position.

[0031] Combined with Figure 2, the main body of the foaming device provided by the embodiment of the present utility model is equipped with a hanging bracket 2 for hanging injection bottles. The hanging bracket 2 has a use state and a storage state. When in use, it is rotated and opened, and the hanging bracket 2 is positioned relative to the main body housing 1. The normal saline bottle is hung on the hanging bracket 2. When the foaming device main body works, the syringe in the foaming injection assembly 100 in the main body can smoothly extract normal saline. In this process, there is no need to prepare an additional infusion stand, saving the floor space occupied by the infusion stand. Therefore, the floor area occupied during use is smaller, which is more conducive to medical staff moving indoors. When not in use, the hanging bracket 2 is rotated so that the hanging bracket 2 and the main body housing 1 are rotated to the same horizontal plane for storage, which is beneficial to reducing the space occupied during storage and facilitating packing. Moreover, since there is no need to transfer the infusion stand additionally, the efficiency and portability during transfer are improved.

[0032] To enable the non-hanging end of the hanging bracket 2 to be positioned at a suitable position when rotated to a suitable position relative to the main body housing 1 by the rotating mechanism 3, the design structures that can be selected include providing a rotary pin structure on the main body housing 1 to block the rotating end (i.e., its non-hanging end) of the hanging bracket 2 that has been rotated in place, or providing other locking structures for position locking. However, this method is slightly complicated to use. Therefore, in this embodiment, preferably, the above-mentioned rotating mechanism 3 is a damping rotating shaft.

[0033] The damping rotating shaft can provide torque by using the friction between the internal damping sheets, so that the rotating part automatically stays at the rotated position after rotation. Only when a greater torque is applied can the current position be changed, and the positioning is reliable. There are various specific structural forms of the damping rotating shaft. It can be a constant force rotating shaft that provides a constant rotational damping force, or a damping rotating shaft whose rotational damping force can be adjusted. Preferably, the damping rotating shaft is a rotating shaft with adjustable force.

[0034] For the convenience of assembly, a disc damping rotating shaft is preferably used. Specifically, referring to Figure 3 and Figure 4 , in combination with Figure 1 、 Figure 2, the damping rotating shaft is an adjustable-force disc damping rotating shaft, which specifically includes a rotating shaft 31, a first turntable 32, a second turntable 33, a nut 34 and a gasket 35. The second turntable 33 is fixedly connected to one end of the rotating shaft 31. The first turntable 32, the gasket 35 and the nut 34 are sleeved on the outside of the rotating shaft 31 in sequence from one end of the rotating shaft 31 close to the second turntable 33 to the end away from the second turntable 33. The nut 34 is threadedly connected to the rotating shaft 31 and squeezes the gasket 35 towards the second turntable 33, thereby generating a rotational damping force between the first turntable 32 and the second turntable 33. The first turntable 32 is fixedly connected to the main body housing 1, and the second turntable 33 is fixedly connected to the non-suspension end of the suspension bracket 2. Thus, if you want to rotate the suspension bracket 2 relative to the main body housing 1, an external force that can overcome this rotational damping force needs to be provided. When this external force is removed, the suspension bracket 2 remains in its current relative position relative to the main body housing 1, ensuring the suspension stability during use and preventing the suspension bracket 2 from automatically opening due to shaking during storage.

[0035] The rotational damping force provided by the above disc damping rotating shaft is regulated by the initial squeezing degree of the nut 34 on the gasket 35. The more the nut 34 is screwed towards the second turntable 33, the tighter the squeeze, the greater the rotational damping force, and the greater the external force torque required to rotate the suspension bracket 2.

[0036] Among them, a rotating shaft mounting hole 101 is provided on the main body housing 1. The rotating shaft mounting hole 101 is a stepped hole, and at least two screw posts 11 distributed circumferentially around the rotating shaft mounting hole 101 are provided on its stepped surface. At least two screw holes corresponding to the screw posts 11 one by one are provided on the first turntable 32, and the first turntable 32 is fixedly connected to the screw posts 11 by screws.

[0037] Among them, an end connection housing 21 is provided at the non-suspension end of the suspension bracket 2. One side of the end connection housing 21 is provided with a groove and this side is inserted into the rotating shaft mounting hole 101 and is blocked in the outer hole section of the rotating shaft mounting hole 101 outside the stepped surface, so that the end connection housing 21 covers the outside of the damping rotating shaft; the end connection housing 21 is fixedly connected to the second turntable 33 by screws, thereby protecting the internal damping rotating shaft structure, preventing it from rusting when encountering water, and at the same time increasing the appearance simplicity and beauty of the main body of this foaming equipment.

[0038] In addition, the disc damping rotating shaft further includes a Figure 4 corner adjustment and limit structure as shown. The corner adjustment and limit structure includes a limit open ring 36 fixedly or integrally connected to the surface of the second turntable 33 facing the first turntable 32, and a limit protrusion 37 fixedly or integrally connected to the surface of the first turntable 32 facing the second turntable 33; when the second turntable 33 rotates with the limit open ring 36 to a preset angle, it is blocked by the limit protrusion 37 and cannot continue to rotate in the same direction. (Specifically, for the limit open ring 36 and the second turntable 33, they are actually fixedly connected or of an integral structure. Figure 4To show the limiting relationship between the limiting open loop 36 and the limiting protrusion 37, the exploded separation state of the two is shown).

[0039] This corner adjustment limiting structure can limit the angular range of the suspension bracket 2 rotating relative to the main machine housing 1 to better control the suspension bracket 2 to open to a suitable position.

[0040] Among them, further make the limiting open loop 36 a 270-degree circular ring, that is, the circumferential angle occupied by the main body part of the limiting open loop 36 is 270 degrees, and the circumferential angle occupied by the opening area is 90 degrees, so that the angular range of the second turntable 33 rotating relative to the first turntable 32 is 90 degrees. The limiting open loop 36 makes the operation of rotating the suspension bracket 2 relative to the main machine housing 1 more convenient and easy to control.

[0041] And / or, set: when the suspension bracket 2 is in the use state, the included angle between the suspension bracket 2 and the horizontal plane is 90 degrees; when the suspension bracket 2 is in the storage state, the suspension bracket 2 is parallel to the horizontal plane, that is, set the initial position of the suspension bracket 2 to extend horizontally. When in use, the suspension bracket 2 can be rotated 90 degrees relative to the main machine housing 1 to reach the vertically upward extended position (the aforementioned suitable position). When not in use, the suspension bracket 2 is rotated 90 degrees relative to the main machine housing 1 and returned to its place for storage. Because when the suspension bracket 2 is in the storage state, the suspension bracket 2 is parallel to the horizontal plane, thus, during storage, it can be ensured that the suspension bracket 2 will not protrude upward or downward from the main machine housing 1, so as to ensure the smallest occupied storage space and further reduce the volume of the storage bag.

[0042] The above "and / or" means that for the foaming equipment main machine provided by the embodiments of the present invention, for the structure of "making the limiting open loop 36 a 270-degree circular ring" and the structure of "when the suspension bracket 2 is in the use state, the included angle between the suspension bracket 2 and the horizontal plane is 90 degrees; when the suspension bracket 2 is in the storage state, the suspension bracket 2 is parallel to the horizontal plane", the design is carried out simultaneously or selectively.

[0043] In addition, in the second aspect of the embodiments of the present invention, a foaming equipment is further provided. Refer to Figure 5 and Figure 6 , this foaming equipment includes an equipment trolley 4, a tray 5, and the foaming equipment main machine provided by any optional implementation manner in the first embodiment. The tray 5 is fixedly installed on the top of the equipment trolley 4, and the foaming equipment main machine is detachably installed on the top surface of the tray 5.

[0044] The foaming device provided by the embodiment of the present utility model adopts a detachable design of the foaming device main body and the device trolley 4. In the scenario where foaming tests need to be carried out in other consulting rooms or other hospitals, the foaming device main body can be detached from the device trolley 4, and only the foaming device main body needs to be carried directly, without the need to push or transport the entire large-scale foaming device, which greatly increases the portability of the foaming device main body, thereby expanding its usage scenarios and improving the utilization rate of the foaming device main body.

[0045] Among them, a fixing nut 12 is fixedly connected to the bottom surface of the main body housing 1 of the foaming device main body. The connection method includes but is not limited to: providing a protruding screw post on the bottom surface of the main body housing 1 of the foaming device main body, and then hot-melting a copper nut on the screw post; a through hole 51 is provided on the tray 5, and the main body housing 1 is detachably installed on the top surface of the tray 5 by screwing a screw through the bottom surface of the tray 5 through the through hole 51 into the aforementioned fixing nut 12. This connection method can stably install the foaming device main body on the tray 5 during use to avoid shaking, and ensure that the foaming device main body can be quickly detached when a transfer is required.

[0046] The tray 5 is preferably a metal tray to increase the bearing capacity.

[0047] Among them, a semi-hidden handle 13 is provided on the main body housing 1 of the foaming device main body, and / or a control pedal 6 is provided on the device trolley 4. The control pedal 6 is signal-connected to the main body control system of the foaming device main body. The semi-hidden handle 13 is used for convenient grasping when the main body is detached from the device trolley 4 and carried for use during transfer; the control pedal 6 allows the user to step on the control pedal 6, thereby replacing the user's need for manual operation to respond to the control instructions sent by the main body control system, and solving the problem that the user cannot respond to some control instructions in a timely manner when both hands are busy. For example, when the foaming device main body completes one process and needs to start the next process, step on the control pedal 6 to respond, and the foaming device main body enters the next process. Responding to the control instructions by stepping on the control pedal 6 greatly improves the efficiency of the foaming test.
