Description

One-way drainage structure of medical injection pump or infusion pump

Technical Field

The patent of the utility model relates to the field of infusion pumps of medical instruments, in particular to a medical infusion pump or an infusion pump one-way drainage structure.

Background

At present, injection pumps and infusion pumps in the field of medical instruments are widely applied in hospitals, can accurately administer medicine to patients, and have safety functions of abnormality detection, automatic alarm and the like, so that the workload of nurses is greatly reduced, the experience level of patients is improved, and a solid foundation is laid for the development of the medical field.

However, in the practical application process, many unexpected situations, such as damage to the infusion pipeline and leakage, occur, and the liquid may enter the pump to cause damage; in addition, the nurse often enters the pump during the process of cleaning the pump, which may damage the circuit board.

Most of infusion pumps or injection pumps in the prior art adopt a drainage groove structure, liquid entering the pump can be discharged from the pump along drainage holes, however, most of drainage structures have small drainage openings due to aesthetic consideration, the drainage is not easy due to the effect of water tension, and meanwhile, when a nurse wipes the infusion pump reversely, the drainage holes at the moment can become water inlet holes, so that the safety of the medical pump is seriously influenced.

Disclosure of Invention

The patent of the utility model aims at solving the shortcoming of above-mentioned prior art, provides a simple structure, and the outward appearance is pleasing to the eye, and can realize the quick drainage of forward, the one-way drainage structures of medical pump who reversely prevents to intake.

The utility model provides a technical scheme that its technical problem adopted: the one-way drainage structure of the medical injection pump or the infusion pump comprises a pump body, wherein a bottom shell is arranged at the bottom of the pump body, a one-way drainage structure is arranged on the bottom shell and comprises an inner waterproof wall and an outer waterproof wall which are fixed on the bottom shell, the inner waterproof wall is arranged inside the outer waterproof wall, the inner waterproof wall is communicated with the inner surface of the bottom shell, more than one inner water outlet is arranged at the bottom of the inner waterproof wall, more than one outer water outlet is arranged at the bottom of the outer waterproof wall, an inner water storage cavity is formed by enclosing the inner waterproof wall, and an outer water storage cavity is formed by enclosing the inner waterproof wall and the.

Preferably, the inner water outlet and the outer water outlet are respectively arranged below the side surfaces of the inner water storage cavity and the outer water storage cavity.

Preferably, the cross-sectional shapes of the inner and outer bulkheads may be circular, quadrangular or polygonal.

Preferably, the inner drainage opening is circumferentially remote from the outer drainage opening.

Preferably, the bottom shell is provided with more than two one-way drainage structures with the same height, and the bottom shell can be used as a support column of the pump body.

Preferably, the connection area of the inner waterproof wall and the inner surface of the bottom shell is positioned at the lower area of the inner surface of the bottom shell, and accumulated water on the inner surface can be conveniently introduced into the inner water storage cavity through the drainage groove.

Preferably, the number of the waterproof walls can be more than two, namely, the waterproof walls are arranged outside the outer waterproof wall, the bottom of the outer waterproof wall is also provided with water outlets, a water storage cavity is formed between the adjacent waterproof walls, and the adjacent water outlets are far away from each other in the circumferential direction.

The utility model discloses profitable effect is: when the water pump is placed in the forward direction, accumulated water in the water pump is accumulated in the inner water storage cavity, and the accumulated water can be quickly discharged out of the pump from the inner water discharge port and the outer water discharge port under the action of water pressure. When the pump is turned over and is cleaned, a lot of ponding can exist on the drain pan, and outer drainage mouth can become the water inlet this moment, but this moment the water inlet has a take the altitude apart from the drain pan surface, and ponding can not get into from outer drainage wall outlet basically, even there is a small amount of water to get into also can store in outer water storage chamber, when cleaning the normal placement that finishes, this part ponding can flow out outside the pump again.

Description of reference numerals: the pump comprises a pump body 1, a bottom shell 2, a one-way drainage structure 3, an inner waterproof wall 3-1, an outer waterproof wall 3-2, an inner drainage port 3-3, an outer drainage port 3-4, an inner water storage cavity 3-5 and an outer water storage cavity 3-6.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

example (b):

a one-way drainage structure of a medical injection pump or infusion pump comprises a pump body 1, wherein a bottom shell 2 is arranged at the bottom of the pump body 1, a one-way drainage structure 3 is arranged on the bottom shell 2, the one-way drainage structure 3 comprises an inner waterproof wall 3-1 and an outer waterproof wall 3-2 which are fixed on the bottom shell 2, the inner waterproof wall 3-1 is arranged inside the outer waterproof wall 3-2, the inner waterproof wall 3-1 is communicated with the inner surface of the bottom shell 2, more than one inner water outlet 3-3 is arranged at the bottom of the inner waterproof wall 3-1, more than one outer water outlet 3-4 is arranged at the bottom of the outer waterproof wall 3-2, an inner water storage cavity 3-5 is formed by the inner waterproof wall 3-1 in a surrounding mode, and an outer water storage cavity 3-6 is formed by the inner.

As shown in fig. 1, the pump is normally placed, four one-way drainage structures 3 are distributed on the bottom shell, and the pump body 1 is placed on a horizontal table top by the four one-way drainage structures 3. The details of the four one-way drainage structures are shown in figures 2 and 3, the inner waterproof wall 3-1 and the outer waterproof wall 3-2 are both circular in section and cylindrical in structure as a whole, and only one of the inner drainage port 3-3 and the outer drainage port 3-4 is arranged, and the difference between the inner drainage port and the outer drainage port is 180 degrees along the axis of the cylindrical structure.

As shown in fig. 4, when the upper surface of the bottom shell is in the presence of water flow when the bottom shell is placed in the forward direction: because the inner waterproof wall 3-1 is internally provided with the inner water storage cavity 3-5, accumulated water in the bottom shell 2 can be gathered to the inner water storage cavity 3-5, and the height h of the inner water storage cavity 3-5 enables the accumulated water in the inner water storage cavity to have certain pressure, so that the accumulated water in the inner water storage cavity can more easily pass through the inner water outlet 3-3 and the outer water outlet 3-4 in sequence and is discharged out of the pump.

When the pump is wiped in reverse (state shown in fig. 5): at the moment, the outer water discharge port 3-4 of the outer waterproof wall 3-2 becomes a water inlet, however, the water discharge port is positioned at a higher position, water flow is difficult to enter the inner part of the outer waterproof wall 3-2 during wiping, even if the water flow enters the inner part of the outer waterproof wall 3-2 (as shown in figure 6), because the inner water discharge port 3-3 is far away from the outer water discharge port 3-4 and does not correspond to the position, the water flow is accumulated in the outer water storage cavity 3-6, and when the pump is wiped and returns to a normal placing state, accumulated water is discharged from the outer water discharge port 3-4 again.
