[0025] The relevant technologies of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] like Figs. 1-5 As shown, this utility model provides a medical squeeze-type auxiliary water cup, including: a cup body 1, a cup lid 2, and a drinking tube 3. The cup lid 2 is detachably sealed and covers the mouth of the cup body 1. The inner opening of the drinking tube 3 is located in the inner cavity of the cup body 1, and the outer opening of the drinking tube 3 extends outside the cup body 1. The part of the drinking tube 3 outside the cup body 1 is an adjustable-angle flexible silicone tube or a flexible hose. The outer opening of the drinking tube 3 is a normally closed duckbill-shaped opening 15. The angle of the flexible silicone tube can be adjusted to a suitable angle for drinking by patients with swallowing difficulties, or it can be easily inserted into the base of the tongue of patients with swallowing difficulties for convenient drinking. The normally closed duckbill opening 15 ensures that even if water in the cup body 1 flows to the outer opening of the drinking tube 3 without external force, it will not flow out of the duckbill opening 15, effectively preventing aspiration, choking, and suffocation. Only when medical staff pump water or squeeze to supply water, and the water pressure is high, can the duckbill opening 15 be opened to allow water to flow out for convenient drinking.

[0027] The side wall of the cup body 1 is provided with a compression zone 4 that can deform inward along the side wall; the wall thickness of the compression zone 4 is 0.8 to 2 mm, and the Shore hardness of the compression zone 4 is 30 to 50 A; the compression zone 4 is used to provide sufficient pressure to the inside of the cup body 1, so that the water inside the cup flows upward from the drinking pipe 3.

[0028] Furthermore, the squeeze-type auxiliary water cup is equipped with a press-type metering water delivery device 5, which includes a piston 6, a cylinder 7, and a piston rod 8. The piston 6 can reciprocate within the cylinder 7. The rodless chamber of the cylinder 7 is connected to the inner cavity of the cup body 1, and the rod chamber of the cylinder 7 is connected to the outside of the cup body 1. The piston rod 8 is connected to the piston 6, and the distal end of the piston rod 8 extends outside the cup body 1. When the piston rod 8 is manually pressed down, the piston 6 applies pressure to the rodless chamber of the cylinder 7, and the rodless chamber of the cylinder 7 transmits the pressure to the inside of the cup body 1, causing the water inside the cup to flow upward from the drinking pipe 3 for drinking.

[0029] Furthermore, the press-operated metering water delivery device 5 is located inside the cup lid 2. The press-operated metering water delivery device 5 is integrated into the cup lid 2, which makes the internal structure of the cup body 1 simple and easy to clean. The cup lid 2 can be removed and cleaned separately, thus making it convenient for users to clean the press-operated metering water delivery device 5. In addition, the press-operated metering water delivery device 5 is located inside the cup lid 2, which makes it convenient to manufacture the cup body 1 and the cup lid 2 separately, improving production efficiency and saving production costs.

[0030] Furthermore, the cup lid 2 is provided with a vent hole 9, which is connected to the rod chamber of the cylinder 7 from the outside to the inside. The vent hole 9 is used to maintain the balance between the rod chamber of the cylinder 7 and the external pressure, so that the operator can press down the piston rod 8 with less effort.

[0031] Furthermore, a scale 10 is provided on the piston rod 8 along the extension and retraction direction of the piston rod 8; the scale makes it convenient for operators to supply water quantitatively according to specific needs. Once the water supply is determined, it is only necessary to press down the fixed scale to achieve quantitative water supply, which is more convenient and faster to use.

[0032] Furthermore, a first spring 11 is sleeved on the piston rod 8 along the extension and retraction direction of the piston rod 8. One end of the first spring 11 is connected to the piston rod 8, and the other end of the first spring 11 is connected to the cup body 1 and / or the cup lid 2. The first spring 11 facilitates the piston rod 8 to return to its original position after being pressed down, so that the next press can be made at any time to dispense water in a metered manner.

[0033] Furthermore, the drinking pipe 3 is equipped with a normally open stop valve 12; the stop valve 12 is used to immediately cut off the water flow in the drinking pipe 3 in an emergency, ensuring the drinking safety of patients with swallowing disorders.

[0034] Furthermore, the stop valve 12 is provided with a return spring 13; the return spring 13 allows the stop valve 12 to be returned to its original position after being pressed, so that it can be used for the next emergency stop at any time.

[0035] Furthermore, the cup lid 2 is threaded onto the mouth of the cup body 1, and a sealing gasket 14 is provided at the connection between the cup lid 2 and the cup body 1.

[0036] Furthermore, the cup body 1 is made of transparent material, and the shape of the cup body 1 includes: cylindrical, drum-shaped, and waisted; different shapes of cup body 1 can be selected according to different needs. The drum-shaped cup body 1 has a larger capacity, while the waisted cup body 1 is more convenient for operators to manually press and squeeze the water out.

[0037] Example

[0038] In this embodiment, the cup body 1 has corrugated squeezing zones 4 on both sides. The wall thickness of the squeezing zone 4 is 1.2±0.1mm, and the Shore A hardness of the squeezing zone 4 is 40A. The squeezing zone 4 is corrugated. The corrugated squeezing zone 4 adopts a three-layer composite structure: outer layer PP, middle layer TPE, and inner layer medical-grade silicone. Directly squeezing the squeezing zone 4 on the cup body 1 triggers a rapid water flow of 200-500ml / min. The Shore A hardness of 40A ensures that the squeezing zone 4 will not deform when the piston 6 is pressed for precise water dispensing, thus not affecting the precise water dispensing volume. When medical personnel squeeze the squeezing zone 4, a large flow of water can be easily generated without consuming a lot of gripping or squeezing force. At the same time, the pressure generated by pressing the piston 6 and the Shore A hardness of 40A allows the water flow to easily open the duckbill valve to ensure water supply.

[0039] The piston rod 8 of the press-to-dispense water device 5 is engraved with a stroke, for example: 0-50mm. Rotate the piston rod 8 to the corresponding buckle to unlock the piston rod 8 and press the piston rod 8 down to the scale position; every 5mm advance dispenses 10ml of water.

[0040] The outer opening of the drinking tube 3 of the cup body 1 is set with an angle adjustment tube, and a duckbill opening 15 is provided at the outer opening of the drinking tube 3. The drinking tube 3 is made of medical grade silicone, and the minimum bending radius of the drinking tube 3 is R8mm.

[0041] The cup body 1 is also equipped with a stop valve 12. Pressing the stop valve 12 cuts off the flow; the water pipe 3 is directly squeezed by the stop valve to stop the flow. The emergency braking mode is activated when there is a choking warning or when the water flow needs to be interrupted immediately. After activation, the water flow can be immediately cut off, effectively preventing aspiration, choking, and suffocation when patients with swallowing disorders drink water.

[0042] The operation process of the squeeze-type auxiliary water cup in this embodiment includes:

[0043] The squeezing area 4 on the side wall of the cup body 1 provides a large amount of water quickly: Cup body 1 → Squeezing area 4 deforms and shrinks → Water stop valve 4 fails, that is, the drinking pipe 3 is normally open (when the pressure is >2kPa) → Drinking pipe 3 main channel (diameter φ5mm) → Duckbill valve 15 unfolds → Oral cavity.

[0044] Pressing the piston rod 8 dispenses a measured amount of water: the piston chamber is pressurized (sealed volume 50ml) → the cup body 1 is pressurized → the drinking tube 3 → the duckbill valve 15 unfolds → the base of the tongue.

[0045] In summary, this invention, by setting a squeezing area on the cup body, a stop valve on the drinking tube, and a normally closed duckbill opening at the outer end of the drinking tube, allows water to be dispensed only by manually pressing the squeezing area under the operation of medical personnel, and the water flow can be stopped at any time by using the stop valve. Therefore, this invention can adjust the water flow in real time according to the patient's condition, or immediately cut off the water flow in an emergency, effectively preventing aspiration, choking, and suffocation when feeding water to patients with swallowing disorders.

[0046] It should be emphasized that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
