Description

Self-emptying negative pressure suction bottle

Technical Field

The utility model belongs to the technical field of the vacuum suction bottle, concretely relates to from evacuation vacuum suction bottle.

Background

The negative pressure suction bottle is commonly used for collecting body fluid and the like in an operation, when the negative pressure terminal of the negative pressure suction bottle is connected, air negative pressure is generated in the negative pressure liquid collection bottle, and the negative pressure guides dirt (such as dirty blood, phlegm and the like) to flow into the negative pressure liquid collection bottle through the conduit. The negative pressure suction bottle is limited by sites, the weight of instruments and the like, the volume which cannot be made by the negative pressure suction bottle is large, when some negative pressure liquid collecting bottles are full, the negative pressure liquid collecting bottles need to be taken down, one person holds the bottles, the other person opens the cover to pour out dirt in the bottles, and in the process of pouring the dirt into a sewage bucket, if dirt particles or liquid drops splash to an operation area, operation infection can be caused, and the dirt particles or the liquid drops can splash to medical staff to increase the occupational exposure risk of the medical staff; if the negative pressure suction bottle is full when a doctor operates in the operation, the operation is stopped to pour sewage, and the operation can be continued until the negative pressure suction bottle reestablishes the negative pressure after the sewage is poured; this will certainly lead to a delay in the time of the operation, an increased risk of the operation and further an increased cost of the operation for the patient.

Therefore, it is necessary to provide a vacuum suction bottle capable of automatically discharging the filth in the bottle.

SUMMERY OF THE UTILITY MODEL

Another object of the utility model is to provide a vacuum aspiration bottle with washing.

In order to solve the technical problem, the utility model discloses a self-emptying negative pressure suction bottle, which comprises a bottle body and a bottle cap, wherein a negative pressure pipe, a liquid inlet pipe, a liquid discharge pipe and a flushing pipe are arranged on the bottle cap in a penetrating way; one ends in the bottle of the negative pressure pipe, the liquid inlet pipe and the flushing pipe extend out to the upper part of the inner cavity of the bottle body, and one end in the bottle of the liquid discharge pipe extends out to the bottom of the inner cavity of the bottle body;

the outer end of the bottle of the negative pressure pipe is connected with the pressure regulator, the outer end of the bottle of the liquid inlet pipe is used for being connected with a sewage discharge outlet of an operation instrument, the outer end of the bottle of the flushing pipe is used for being connected with a clean water source, the outer end of the bottle of the liquid discharge pipe is connected with a sewage pump, and the sewage pump is used for pumping sewage into the large-scale sewage collecting device from the bottle body.

Preferably, the bottle further comprises a sensor arranged on the upper part of the outer side of the bottle body or the bottom of the bottle cap, and the sensor is triggered when the liquid level in the bottle body reaches the height of the sensor.

Preferably, the drain pipe is provided with a check valve for preventing the reverse flow of the sewage.

Preferably, the flushing pipe is provided with an electromagnetic valve.

Furthermore, the electromagnetic valve and the sewage pump are in signal connection with the sensor.

Preferably, a spray head is arranged at one end of the flushing pipe in the bottle.

The utility model discloses a from evacuation negative pressure suction bottle has following advantage at least:

the utility model discloses a from evacuation negative pressure suction bottle simple structure, it is with low costs, can automatic evacuation inside filth after the liquid level reachs the take the altitude in the bottle, still can wash in the bottle after the evacuation, save the manual work, be favorable to guaranteeing going on smoothly of operation.

Detailed Description

The present invention is further described in detail below with reference to examples so that those skilled in the art can implement the invention with reference to the description.

It will be understood that terms such as "having," "including," and "comprising," when used herein, do not preclude the presence or addition of one or more other elements or groups thereof.

As shown in fig. 1, the self-emptying negative pressure suction bottle comprises a bottle body 1 and a bottle cap 2, wherein a negative pressure pipe 3, a liquid inlet pipe 4, a liquid discharge pipe 5 and a flushing pipe 6 are arranged on the bottle cap in a penetrating manner; one ends in the bottle of the negative pressure pipe, the liquid inlet pipe and the flushing pipe extend out to the upper part of the inner cavity of the bottle body, and one end in the bottle of the liquid discharge pipe extends out to the bottom of the inner cavity of the bottle body;

the outer one end of bottle of negative pressure pipe is connected with voltage regulator 7, the outer one end of bottle of feed liquor pipe is used for being connected with the drain of operation instrument, the outer one end of bottle of flushing pipe is used for being connected with clean water source, the outer one end of bottle of fluid-discharge tube is connected with dredge pump 8, dredge pump is used for taking the filth out large-scale filth collection device from the body.

The bottle cap further comprises a sensor 9 arranged at the bottom of the bottle cap, and the sensor is triggered when the liquid level in the bottle body reaches the height of the sensor. The sensor can adopt a non-contact infrared sensor (arranged in or out of a bottle), or a contact pressure sensor, a capacitance sensor (arranged in the bottle) and the like.

The drain pipe is provided with a check valve 510 for preventing the reverse flow of the sewage. The flushing pipe is provided with an electromagnetic valve 610. The electromagnetic valve has much higher cost than the one-way valve, and the liquid discharge pipe is contacted with dirt and can be used at one time or replaced frequently, so that the one-way valve with low cost is more suitable for the liquid discharge pipe; the flushing pipe is not in direct contact with the dirt, so that the electromagnetic valve which is high in cost and can be used for a long time can be adopted.

The electromagnetic valve and the sewage pump are in signal connection with the sensor. So that the electromagnetic valve, the sewage pump and the sensor can be linked.

One end in the bottle of flushing pipe is equipped with shower nozzle 620 for the inner wall of the body can be more even by the erode.

In the use, when negative pressure imbibition, solenoid valve and check valve close, rise gradually until triggering the sensor along with filth liquid level in the bottle, the sensor sends out the signal after being triggered, and the dredge pump starts at this moment and begins to draw the filth from the bottle and discharge in large-scale filth collection device (the voltage regulator is incessant). The solenoid valve waits for a period of time (this time quantum is used for the interior filth evacuation of bottle) after receiving the sensor signal and opens again, and foam, residue and the residual liquid that leave over in the bottle are washed out to clean rivers play, make in the bottle obtain preliminary washing, reduce pollutant concentration, prevent excessive sediment such as residue. After cleaning for 1-2 times (after each cleaning, water is discharged by a sewage pump, and a certain pipeline flushing effect can be achieved), the electromagnetic valve and the one-way valve are closed again, and the negative pressure suction bottle can be normally used.

While the embodiments of the invention have been disclosed above, it is not limited to the applications listed in the description and the embodiments, which are fully applicable in all kinds of fields suitable for the invention, and further modifications may be readily made by those skilled in the art, and the invention is therefore not limited to the specific details and embodiments shown and described herein, without departing from the general concept defined by the claims and their equivalents.
