Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a water collecting cup device for a ventilator. Background Art

[0002] In modern clinical medicine, ventilators, as an effective means of artificially replacing spontaneous ventilation, play a very important role in the field of modern medicine. Ventilators are vital medical devices that can prevent and treat respiratory failure, reduce complications, and save and prolong patients' lives.

[0003] The ventilator water collection cup is mainly used to collect water vapor and other liquids generated during the use of the ventilator to prevent the liquid from entering the ventilator and breathing circuit, causing ventilator failure or patient injury.

[0004] Patients who need to use a ventilator are generally those suffering from respiratory failure due to various reasons, those undergoing anesthesia respiratory management during major surgery, respiratory support therapy, and emergency resuscitation. These patients usually have weakened immunity, and even the slightest infection can cause accidents.

[0005] Since the traditional water collection cup is a threaded split type, the cup body needs to be unscrewed through the threads to pour out the water in the bottle body, causing the inside of the cup body to be exposed to bacteria and viruses from the external environment. If the cup body is screwed on again, the patient will be infected. Utility Model Content

[0006] In view of the defects in the prior art, the utility model provides a water collecting cup device for a ventilator, so as to improve the sealing performance of the water collecting cup of the ventilator and reduce the probability of infection of the patient.

[0007] The utility model provides a water collecting cup device for a ventilator, comprising a cup body, a water collecting cavity inside the cup body, water collecting pipes communicating with the water collecting cavity are arranged on both sides of the top of the cup body, and the water collecting pipes are connected to the ventilator;

[0008] A piston mechanism, the piston mechanism comprising a piston, the piston is sealingly and slidingly matched with the side wall of the water collecting chamber, the piston divides the water collecting chamber into a water inlet chamber and a water discharge chamber from top to bottom, a piston rod is connected to the side of the piston close to the water discharge chamber, the end of the piston rod away from the piston extends out of the bottom of the cup body and is connected to a handle, and an elastic member is sleeved on the outer periphery of the piston rod, the elastic member is compressed and abutted between the handle and the bottom of the cup body;

[0009] The piston is provided with a water hole, which is a tapered hole with a larger top and a smaller bottom. The water hole is arranged close to the piston rod, and the water inlet cavity and the drainage cavity are connected through the water hole.

[0010] A drain pipe is arranged at the bottom of the cup body, and a valve is arranged on the drain pipe.

[0011] It can be seen from the above technical scheme that the utility model provides a ventilator water collection cup device, in which the water vapor generated by the ventilator gradually condenses into water after passing through the water collection pipe, and the water enters the water inlet chamber through the water collection pipe, and the water in the water inlet chamber can drip into the drainage chamber through the water hole on the piston. When there is a lot of water in the drainage chamber, the medical staff can open the valve and pull the piston rod downward. Under the action of the pulling force, the piston rod drives the piston to move downward synchronously. Due to the sealing and sliding fit between the outer wall of the piston and the inner wall of the water collection chamber, there is a large friction between the two, that is, the outer edge of the piston is subject to a large resistance, and the middle part of the piston is directly connected to the piston rod, which is subject to a large pulling force. Under the combined effect of the pulling force and the resistance, the middle part of the piston will be deformed downward to a certain extent. Under the action of the deformation, the inner wall of the water hole close to the piston rod side is deformed downward, so that the small diameter end of the water hole is gradually closed, and the connection between the water inlet chamber and the drainage chamber is roughly blocked. At the same time, the piston moves downward, compresses the drainage chamber space, and the water in the drainage chamber is pressed out through the drainage pipe. When drainage is completed, the valve is closed, and the medical staff releases the piston rod, which is reset under the action of the elastic member, and the piston is also reset. This achieves drainage without the inside of the water collection cup contacting the external environment, and compared with the nurse pouring the liquid, pulling the piston rod is more efficient in drainage.

[0012] Optionally, there are two water holes, and the two water holes are respectively close to the two sides of the piston rod. Optionally, there are two water holes, and the two water holes are respectively located on the two sides of the piston rod.

[0013] Optionally, the ventilator is provided with a water collecting pipe connected to the water collecting pipe, and the water collecting pipe is connected to the water collecting pipe via a first hose connector;

[0014] A water outlet is provided at the bottom of the cup body, and the water outlet is connected to the drain pipe through a second hose connector.

[0015] Optionally, the valve is a flow stop clamp.

[0016] Optionally, the elastic member is a spring.

[0017] Optionally, the piston is a rubber piston.

[0018] Optionally, the bottom of the piston is provided with two inverted conical bosses protruding downward, the two bosses are coaxially arranged with the two water holes, and the water holes pass through the bottoms of the corresponding bosses. The small diameter end area of ​​the water hole is increased, so when the piston is deformed, the contact area of ​​the small diameter end of the water hole is increased, so that the blocking effect of the water inlet cavity and the water discharge cavity is enhanced.

[0019] Optionally, the inner diameter of the large diameter end of the water hole is 15 mm, and the inner diameter of the small diameter end of the water hole is 1.5 mm;

[0020] The thickness of the piston is 15 mm. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] like Figure 1-2As shown, a water collecting cup device for a ventilator provided in this embodiment includes a cup body, the interior of the cup body has a water collecting chamber 4, water collecting pipes 1 are arranged on both sides of the top of the cup body, the water collecting pipes 1 are connected to the water collecting pipes 1 through a first hose connector 2, and the water collecting pipes 1 are connected to the ventilator. Specifically, two water collecting pipes 3 are arranged on the ventilator, and the water collecting pipes 3 are connected to the corresponding water collecting pipes 1 through the first hose connector 2. The water vapor generated by the ventilator gradually condenses into water after passing through the water collecting pipe 1, and the water enters the water collecting chamber 4 through the water collecting pipe 3. A water outlet 7 is arranged at the bottom of the cup body, and the water outlet 7 is connected to the drain pipe 6 through a second hose connector 8. A valve 9 is arranged on the drain pipe 6, and the valve 9 is specifically a stop clamp.

[0031] Specifically, the first hose connector 2 and the second hose connector 8 have the same structure. The inner circumferences at both ends of the first hose connector 2 are respectively interference fit with the outer circumferences of the water collecting pipe 1 and the water collecting pipe 3, and the inner circumferences at both ends of the second hose connector 8 are respectively interference fit with the outer circumferences of the water outlet 7 and the drain pipe 6.

[0032] The ventilator water collection cup device of this embodiment also includes a piston mechanism 5, which includes a piston 501 made of rubber material, and the piston 501 is sealed and slidably matched with the side wall of the water collection chamber 4. The piston divides the water collection chamber 4 into a water inlet chamber 401 and a drainage chamber 402. The side of the piston 501 close to the drainage chamber 402 is connected to a piston rod 502, and the end of the piston rod 502 away from the piston 501 extends out of the bottom of the cup body and is connected to a handle, and an elastic member 503 is sleeved on the outer periphery of the piston rod, and the elastic member is compressed and abutted between the handle and the bottom of the cup body. Specifically, the elastic member 503 is a coil spring.

[0033] Furthermore, the piston 501 is provided with two water holes 5011, which are respectively close to the two sides of the piston rod 502. The water holes 5011 are tapered holes with a larger top and a smaller bottom, and are provided close to the piston rod 502. The water inlet chamber 401 and the water outlet chamber 402 are connected through the water holes 5011.

[0034] Furthermore, the bottom of the piston 501 is provided with two inverted conical bosses protruding downward, and the two bosses are respectively coaxially arranged with the two water holes 5011, and the water holes 5011 pass through the bottom of the corresponding bosses. In this embodiment, the inner diameter of the large diameter end of the water hole 5011 is 15 mm, and the inner diameter of the small diameter end of the water hole is 1.5 mm; the thickness of the piston is 15 mm.

[0035] In practice, the number of the water holes 5011 can also be designed to be 1, 3, or other numbers, as long as the conduction or disconnection between the water inlet cavity 401 and the drainage cavity 402 can be satisfied.

[0036] The working principle of the ventilator water collecting cup device of this embodiment is as follows: the water vapor generated by the ventilator gradually condenses into water after passing through the water collecting pipe 1, and the water enters the water inlet chamber 401 through the water collecting pipe 1. The water in the water inlet chamber 401 can drip into the drainage chamber 402 through the water hole 5011 on the piston 501. When there is a lot of water in the drainage chamber 402, the medical staff can open the valve 9 and pull the piston rod 502 downward. Under the action of the pulling force, the piston rod 502 drives the piston 501 to move downward synchronously. Due to the sealing and sliding fit between the outer wall of the piston 501 and the inner wall of the water collecting chamber 4, there is a large friction between the two, that is, the outer edge of the piston 501 is subject to a large resistance, and the middle part of the piston 501 is directly connected to the piston rod 502, which is subject to a large pulling force. Under the combined action of the pulling force and resistance, the middle part of the piston 501 will be deformed downward to a certain extent. Under the action of the deformation, the inner wall of the water hole 5011 close to the piston rod 502 is deformed downward, so that the small diameter end of the water hole 5011 is gradually closed, roughly blocking the connection between the water inlet chamber 401 and the drainage chamber 402. At the same time, the piston 501 moves downward, compressing the space of the drainage chamber 402, and the water in the drainage chamber 402 is pressed out through the drain pipe 6. When drainage is completed, the valve 9 is closed, and the medical staff releases the piston rod 501 . The piston rod 501 is reset under the action of the elastic member 503 , and the piston 501 is also reset accordingly.
