Description

Technical Field

[0001] This utility model relates to the field of human necessities, further to the field of ventilators, and especially to the field of medical auxiliary equipment, particularly a water collection cup for ventilator tubing. Background Technology

[0002] Currently, ventilators used in clinical settings have heating and humidification functions. When used for a long time, condensation will accumulate in the tubing. Excessive accumulation of condensation can easily cause patients to choke through the nasal cannula. Therefore, a water collection cup is usually connected in series with the ventilator tubing to collect the condensation.

[0003] In existing technology, the condensate cup usually requires unscrewing the cup body to pour out the condensate accumulated in the condensate cup, which is very inconvenient. If the condensate could be directly suctioned out by connecting it to the negative pressure socket used for suctioning at the head of the hospital bed, the efficiency of condensate emptying would be greatly improved. However, if the condensate cup is directly connected to the negative pressure socket, the negative pressure will affect the main circuit of the ventilator, drawing oxygen and air from the patient's body through the main circuit, which will affect the patient. Summary of the Invention

[0004] The purpose of this utility model is to provide a condensate cup for ventilator tubing, which solves the technical problem that the condensate in the condensate cup of ventilator tubing needs to be emptied frequently by hand in the prior art.

[0005] A ventilator tubing water collection cup includes a cup body with a cup lid and a ventilator tubing interface on the cup lid. A partition is horizontally arranged inside the cup lid, a pressure rod is located at the top of the cup lid, a suction tube is located on one side of the cup lid, and a one-way valve is located on the other side of the cup lid. A through hole is formed in the partition. A press valve is located below the partition and is situated on the central axis of the through hole. The pressure rod is vertically arranged relative to the partition, with one end passing through the top of the cup lid and connected to the press end of the press valve. A plug is horizontally arranged on the pressure rod, with a diameter larger than the diameter of the through hole, and the plug covers the through hole. One end of the suction tube is located outside the cup lid, and the other end is located near the bottom of the cup body. The press valve is connected to the suction tube. The inlet end of the one-way valve is located outside the cup lid, and the outlet end is located inside the cup lid.

[0006] Furthermore, the inner wall of the cup is vertically provided with an identification groove, and a float ball is provided in the identification groove.

[0007] Furthermore, the outer wall of the cup is provided with graduations along the direction of the marking groove.

[0008] Compared with existing technologies, the advantages of this invention are positive and obvious:

[0009] 1. The suction tube of this utility model is connected to the negative pressure socket, and the condensate in the water cup is sucked away by negative pressure, thereby improving the efficiency of condensate pouring.

[0010] 2. The lever of this utility model is connected to the pressure valve. The pressure valve will connect to the suction tube only after the lever is pressed down, so that the water suction behavior is controllable. At the same time, when the lever is pressed down, the plug blocks the through hole, so that the negative pressure area is isolated from the main circuit of the ventilator, avoiding the impact on the patient when the negative pressure water is suctioned.

[0011] 3. The one-way valve of this utility model provides air intake in the negative pressure area when drawing water under negative pressure, which helps to facilitate smooth water intake.

[0012] The working principle of this utility model:

[0013] The suction tube is connected to a negative pressure socket at the head of the hospital bed, allowing condensate to be drawn directly from the condensate cup, greatly improving the efficiency of condensate emptying. A control lever is installed on the condensate cup lid, connected to a pressure valve. The valve only connects to the suction tube when the lever is manually pressed, thus making the suction process controllable. Simultaneously, when the lever is pressed down, the plug blocks the through-hole, isolating the negative pressure area from the ventilator main circuit and preventing any impact on the patient during negative pressure suction.

[0014] It is also equipped with a one-way valve, which provides air intake to the negative pressure area when drawing water under negative pressure, thus assisting in a smooth water drawing process. Attached Figure Description

[0020] The following embodiments will further illustrate the present invention, but are not intended to limit the present invention.

[0021] Example 1

[0022] like Figures 1 to 3 As shown, this embodiment provides a ventilator tubing water collection cup, including a cup body 2, a cup cover 1 threadedly connected to the cup body 2, and two ventilator tubing interfaces 101 provided on the cup cover 1 for connecting the water collection cup in series with the ventilator tubing.

[0023] A partition 102 is horizontally installed in the middle of the cup lid 1. The partition 102 divides the entire water collection cup into two areas: the upper area is a non-negative pressure area and the lower area is a negative pressure area.

[0024] A circular through hole 103 is provided on the partition 102. A valve seat 104 is provided at the center of the through hole 103. The valve seat 104 is located below the partition 102. The top edge of the valve seat 104 is fixed to the partition 102 by fixing rods on both sides, thereby fixing the valve seat 104 in the center of the through hole 103. A press valve 6 is snapped into the valve seat 104. The press valve 6 is also located below the partition 102 and is located on the central axis of the through hole 103. The press valve 6 includes a press end and two ports. Pressing the press end connects the two ports.

[0025] A pressure rod 3 is vertically installed on the top of the cup lid 1 relative to the partition 102. The top of the pressure rod 3 is located outside the water cup, and the bottom of the pressure rod 3 passes through the top of the cup lid 1 and is fixedly connected to the pressing end of the pressing valve 6. When the pressure rod 3 is manually pressed, the pressing end is pressed down, which in turn connects the pressing valve 6, thereby realizing the controllable water absorption behavior.

[0026] A disc-shaped plug 301 is horizontally fixed to the pressure rod 3. The pressure rod 3 passes through the center of the plug 301. The diameter of the plug 301 is larger than the diameter of the through hole 103. The distance between the plug 301 and the through hole 103 is the same as the stroke of the pressing end of the pressure valve 6. When the pressure rod 3 is pressed, the plug 301 tightly covers the through hole 103, thereby separating the negative pressure area from the non-negative pressure area and avoiding the negative pressure water absorption from affecting the non-negative pressure area.

[0027] A suction tube 5 is fixed to one side of the cup lid 1. One end of the suction tube 5 is located outside the cup lid 1 and is connected to a negative pressure socket via a flexible tube. The other end of the suction tube 5 extends downward to the bottom of the cup body 2 for easy water intake. A pressure valve 6 is connected to the suction tube 5 to control whether the suction tube 5 is connected. Specifically, the pressure valve 6 includes an inlet and an outlet. After a section of the suction tube 5 is broken, the two broken ends are connected to the inlet and outlet respectively, thus connecting the pressure valve 6 to the suction tube 5. A plug is connected below the pressing end of the pressure valve 6. A spring is installed below the plug. Before pressing, the plug blocks the inlet and outlet, preventing them from connecting. After pressing, the plug moves downward, connecting the inlet and outlet. After releasing the pressing end, the plug returns to its blocked state via the spring.

[0028] A one-way valve 4 is fixed to the other side of the cup lid 1. The air inlet of the one-way valve 4 is located outside the cup lid 1, and the air outlet is located inside the cup lid 1, so that air outside the cup can enter the cup in one direction. On the one hand, it prevents oxygen from escaping when the ventilator supplies oxygen, and on the other hand, it provides air intake to the negative pressure area when the negative pressure absorbs water, so as to balance the air pressure and facilitate the negative pressure to draw out the condensate.

[0029] How to use this embodiment:

[0030] In use, the outer end of the suction tube 5 is connected to the negative pressure socket through a flexible tube. The pressure rod 3 is manually pressed, which in turn drives the pressing end of the pressing valve 6 to press down, so that the suction tube 5 is connected. At the same time, the plug 301 blocks the through hole 103, so that an isolated negative pressure area is formed below the partition 102. When suctioning, outside air enters the negative pressure area through the one-way valve 4, thereby supplying air to the negative pressure area. The condensate in the water cup is sucked out through the suction tube 5, achieving the effect of quickly draining the condensate.

[0031] After the condensate is sucked up, release the pressure rod 3 and close the pressure valve 6, so that the suction tube 5 returns to the disconnected state; lift the plug 301, so that the non-negative pressure area is connected to the negative pressure area, and the water collection cup returns to the normal use state to continue collecting condensate.

[0032] Example 2

[0033] like Figure 4 As shown, this embodiment is a preferred embodiment of embodiment one. A vertically arranged marking groove 201 is provided on the inner wall of the cup body 2, and a float 202 is installed inside the marking groove 201. The float 202 is red for better visibility and can move within the marking groove according to the liquid level. A scale 7 is provided on the outer wall of the cup body 2 along the direction of the marking groove 201. By observing the position of the float 202, it is easier to understand the content of condensate in the water collection cup, reminding medical staff to drain the condensate in a timely manner.

[0034] In the above embodiments, the push valve, check valve, and negative pressure socket are all well-known technical solutions, and their structures and principles will not be described in detail.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
