Abstract

The utility model discloses a negative pressure liquid suction device which is a medical device, mainly comprising an electric pump 10, a negative pressure chamber 6, an air purifying chamber 2, pipelines 3, 4, 5, 8, a suction head and an ob'20. When the electric pump works, the negative pressure suction head combination 06'1 can be formed to directly suck the urine from a U-shaped structure arranged in the artificial making drain operation abdominal cavity of the patient. The urine can not overflow to soak the skin. Thus the pain can be reduced and the possibility of infected can be decreased. The healing of the operation cut of the patient can not be influenced, and the nursing is convenient.

Description

Negative liquid suction device

The negative pressure aspirator belongs to medical apparatus and instruments.

Up to now, manually making in the Lou operation in the clinical medicine use, all is to settle a U-shaped structure at patient's intraperitoneal, to store patient's urine.One end of this U-shaped structure is connected to kidney, to collect urine; The other end is connected to the mouth of making on the skin leakage of urinating.When the urine in the U-shaped structure is stored into when urinating open height, urine mouthful is overflowed from urinating.Also there is the conduit of employing to insert mouthful water conservancy diversion of urinating, or adopts rubber bulb pump to aspirate at the mouth of urinating.No matter yet be to adopt which kind of aforesaid way drain, urine will be impregnated into the skin of the mouth of urinating still unavoidablely, it is the surface of surgical wound, even the skin at other positions of patient body of stretching, especially, usually cause and infect or decubital ulcer the patient of long-term bed, cause suffering, and must have the special messenger to nurse, and come the surface of continuous cleaning skin, cause nursing difficulty.Moreover the standard negative pressure of using is inhaled the urine means now, and pipette is directly inserted in the mouth of urinating, and makes whole U-shaped structure when suction, all is subjected to negative pressure, causes patient's affected part surgical wound to be difficult to healing, is to cause inflammation after the operation so that one of reason of hyperpyrexia.

The present invention aims to provide a kind of negative pressure aspirator new equipment, after overcoming existing usefulness and manually making Lou operation, the drawback of patient urinates means, the skin that urine can be impregnated into again urinate mouthful, and can not make the unlikely negative pressure that is subjected to integral body of Intraabdominal U-shaped structure, and just can directly from the U-shaped structure, derive urine, both reduced the postoperative misery of patient, reduce possibility of infection, made things convenient for patient's nursing again.

The alleged negative pressure aspirator of the present invention is made up of electrodynamic pump, vacuum table, urine bottle, absorption heads, air filter chamber, conduit and " ob " etc.Wherein " ob " is a kind of novel product for women menstruation, utilizes the characteristics of its tool antiseptic hygiene and high dry, can draw moisture content, liquid to greatest extent.Provide one embodiment of the present of invention below:

The structural representation of Fig. 1, negative pressure aspirator.

The structural representation of Fig. 2, negative pressure aspirator absorption heads.

Fig. 3, negative pressure aspirator absorption heads and " ob " bonded sketch map.

Among the figure: the drawing head 2, the air filter chamber that 1, combine " ob "

3, air intake duct 4, air inlet pipe purifies air

5, pipette 6, liquid containing bottle (negative pressure chamber)

7, liquid containing bottle carriage 8, exhaust tube

9, vacuum table 10, electrodynamic pump

11, electrodynamic pump air vent 12, electrodynamic pump power connection

15, the imbibition pipeline of absorption heads

16, the front cavity of absorption heads imbibition pipeline

17, the annular groove on the absorption heads

18, the interface of the absorption heads and the pipe that purifies air

19, the interface of absorption heads and pipette

20、“ob”

Wherein absorption heads is crucial parts, and available non-toxic plastic makes.In two passages are arranged, one is that admission line 14, two is imbibition pipeline 15, their front end has a cavity 16 in the taper front portion 13 of absorption heads in imbibition pipeline 15 small jar 13 imports before the absorption heads taper.When the taper anterior 13 of absorption heads inserts " ob " 20 rear portions, be unlikely the obstruction that causes imbibition pipeline 15.Can be wrapped on the annular groove 17 at the cord that has on the absorption heads on the annular groove 17 " ob " 20, assurance " ob " 20 is unlikely and comes off.The interface 19 that interface 18 that admission line 14 is connected with the air inlet pipe 4 that purifies air and imbibition pipeline 15 and pipette 5 are arranged at the afterbody of absorption heads.The absorption heads 1 that combines " ob " 20 is inserted patient manually to be made in the U-shaped structure of omitting in printing in the urine mouth, energized 12, electrodynamic pump 10 runnings, air in the liquid containing bottle (negative pressure chamber) 6 is sucked from air vent 11 and discharges, liquid containing bottle 6 forms negative pressure, urine in the U-shaped structure is by " ob " 20 absorptions, then via the cavity 16 of imbibition pipeline 15 front ends on the absorption heads taper front portion 13, the interface 19 of imbibition pipeline 15 and pipette 5, pipette 5 is drawn to liquid containing bottle 6, and liquid containing bottle 6 can be pacified carriage 7 for simplicity.Simultaneously, air enters air purifying room 2 clean air from air inlet pipe 3 and manages 4 from purifying air, interface 18, and the admission line 14 on the absorption heads advances " ob " 20, has formed air loop, finishes the process that suction is urinated.

Claims

1, the negative pressure aspirator is a kind of medical apparatus and instruments, it is mainly by electrodynamic pump 10, vacuum table 9, liquid storage is (negative pressure chamber) 6 also, connection tube 3,4,5,8, air purifying room 2 combines the absorption heads 1 of " ob " 20 and forms, it is characterized in that: admission line 14 and imbibition pipeline 15 are arranged on the absorption heads, their front ends are all in the taper front portion 13 of absorption heads, in anterior 13 opening parts of absorption heads taper one cavity 16 is arranged at imbibition pipeline 15, annular groove 17 is arranged on absorption heads, at the tail end of absorption heads the interface 19 of the interface 18 of admission line 14 and the air inlet pipe 4 that purifies air and imbibition pipeline 15 and pipette 5 is arranged, and absorption heads taper anterior 13 to insert former be product for women menstruation " ob " 20.
