Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

All of the features disclosed in the present application, or all of the steps in any method or process disclosed, may be combined in any combination, except for mutually exclusive features and/or steps.

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example one

As shown in fig. 1 to 3, the drip cup capable of automatically stopping liquid in this embodiment includes a housing 1, a liquid inlet 11 at the top thereof and a liquid outlet 11 at the bottom thereof, and a partition plate 2 disposed in the housing 1 and dividing the inner cavity of the housing 1 into an upper chamber 21 and a lower chamber 22, wherein a liquid guide tube 3 for communicating the upper chamber 21 with the lower chamber 22 is disposed on the partition plate 2;

a connecting rod 5 and a cover plate 4 connected to the top of the connecting rod 5 are also included, the connecting rod 5 is inserted into the liquid guide tube 3, the cover plate 4 is closely covered on the upper nozzle 31 of the liquid guide tube, and when the cover plate 4 is acted by the floating force of the liquid in the upper chamber 21, the cover plate 4 moves upwards to be away from the upper nozzle 31 of the liquid guide tube, so that the liquid in the upper chamber 21 can flow into the lower chamber 22 through the liquid guide tube 3.

When the infusion apparatus adopts the drip cup of the utility model, the cover plate 4 is covered on the upper pipe orifice 31 of the catheter in a closed way in the initial state before the infusion is started, obviously, the diameter of the cover plate 4 is larger than the inner diameter of the upper pipe orifice 31 of the catheter; when normal transfusion is started, liquid enters the upper cavity 21 from the liquid inlet 11 of the housing 1, after the liquid in the upper cavity 21 gradually accumulates and rises, the cover plate 4 moves upwards to leave the upper pipe opening 31 of the liquid guide pipe under the action of liquid buoyancy, at the moment, the liquid in the upper cavity 21 can flow into the lower cavity 22 through the liquid guide pipe 3, and then flows to a clinical patient from the liquid inlet 11 of the housing 1. After the liquid in the infusion bottle is completely infused, the liquid in the upper chamber 21 gradually descends, the cover plate 4 also gradually descends until the cover plate 4 is covered on the upper pipe orifice 31 of the liquid guide pipe in a sealing way, and the upper pipe orifice 31 of the liquid guide pipe is sealed, at the moment, the liquid in the lower chamber 22 can not be delivered to the patient any more, and therefore the purpose of automatic liquid stopping is achieved.

Furthermore, a limiting mechanism for preventing the connecting rod 5 from separating from the catheter 3 is arranged on the connecting rod 5. During normal transfusion, the cover plate 4 moves upwards to leave the upper pipe orifice 31 of the liquid guide pipe under the action of liquid buoyancy, the connecting rod 5 rises along with the cover plate 4, and the situation that the connecting rod 5 is separated from the liquid guide pipe 3 can be avoided due to the design of the limiting mechanism. Without the design of the limiting mechanism, once the connecting rod 5 is separated from the catheter 3, after the liquid in the infusion bottle is infused, the connecting rod 5 is difficult to return into the catheter 3, so that the cover plate 4 is difficult to close again to cover the upper tube opening 31 of the catheter, which results in that automatic liquid stopping cannot be realized. Of course, if the rod 5 is long enough, the rod 5 will not be detached from the catheter 3; that is, when the cover plate 4 is raised to the limit position by the buoyancy of the liquid, the lower section of the link 5 remains in the liquid guide tube 3.

Alternatively, in one embodiment, as shown in fig. 1, the limiting mechanism comprises a pull rope 6 connected between the bottom of the connecting rod 5 and the bottom of the catheter 3, and the connecting rod 5 can be prevented from being separated from the catheter 3 by the pull rope 6. During normal transfusion, under the action of liquid buoyancy, the cover plate 4 moves upwards to drive the connecting rod 5 to move upwards, and after the pull rope 6 is stretched straightly, the cover plate 4 and the connecting rod 5 cannot continuously rise, so that the aim of preventing the connecting rod 5 from being separated from the liquid guide tube 3 is fulfilled. Preferably, the pull cord 6 has a plurality (e.g., 4) connected in a circumferential array between the bottom of the connecting rod 5 and the bottom of the catheter 3.

Alternatively, in another embodiment, as shown in fig. 2, the limiting mechanism is a baffle 7 disposed at the bottom of the connecting rod 5, the length of the connecting rod 5 is greater than the length of the catheter 3, the baffle 7 is located below the lower nozzle 32 of the catheter, and the baffle 7 cannot pass through the catheter 3. In particular, the diameter of the baffle 7 is greater than the inner diameter of the lower nozzle 32 of the catheter, so as to achieve the purpose that the baffle 7 cannot pass through the catheter 3. During normal infusion, under the action of liquid buoyancy, the cover plate 4 moves upwards to drive the connecting rod 5 and the baffle plate 7 to move upwards, and when the baffle plate 7 touches the lower pipe opening 32 of the liquid guide pipe, the cover plate 4, the connecting rod 5 and the baffle plate 7 cannot continuously rise, so that the aim of avoiding the connecting rod 5 from being separated from the liquid guide pipe 3 is fulfilled.

Further, as shown in fig. 3, the baffle 7 is provided with a liquid passing port 71 through which liquid can pass. After the liquid flows into the liquid guide tube 3 from the upper chamber 21, the liquid can flow into the lower chamber 22 from the liquid passing port 71 of the baffle 7. The liquid passing port 71 may be a notch or a hole formed around the baffle 7.

Further, as shown in fig. 1 and 2, a liquid passing hole 33 communicating with the lower chamber 22 is laterally provided at a lower portion of the liquid guide tube 3. After the liquid flows into the liquid guide tube 3 from the upper chamber 21, the liquid can flow into the lower chamber 22 from the liquid passing hole 33 of the liquid guide tube 3. Preferably, there are a plurality (e.g. 4) of liquid passing holes 33 arranged circumferentially and laterally on the lower part of the liquid guiding tube 3.

Alternatively, in one embodiment, as shown in figure 1, the bottom of the cover plate 4 is provided with a resilient gasket 41 that can be closed over the upper nozzle 31 of the catheter. The elastic gasket 41 can more reliably block the upper nozzle 31 of the catheter. The elastic pad 41 may be made of medical material having elasticity such as silicone.

Alternatively, in another embodiment, as shown in fig. 2, the bottom of the cover plate 4 is provided with a circular truncated cone 42 adapted to the upper nozzle 31 of the catheter, and the circular truncated cone can be covered on the upper nozzle 31 of the catheter in a sealing manner. The truncated cone 42 (with taper) can more reliably seal the upper nozzle 31 of the catheter. The circular truncated cone 42 may be an elastic circular truncated cone, or may be a hard circular truncated cone. The circular truncated cone 42 can be made of medical materials such as silica gel.

Further, the catheter 3 is coaxial with the housing 1. In other words, the liquid guide tube 3 is provided at the center of the partition plate 2.

Furthermore, the drip cup is made of transparent medical materials. The liquid condition in the drip cup is convenient to observe.
