Description

Medical suction pump

This utility model relates to a kind of medical apparatus and instruments, especially relates to a kind of patient's medical absorber of pus and blood, secretions on one's body that is used to attract.

Medical suction pump is a kind of hospital medical apparatus and instruments very commonly used, and existing medical suction pump comprises vacuum pump and dirt bottle, and sealing of dirt bottle is inserted with two tubes, and a pipe is connected to the attraction rifle, and another root pipe is connected to the air entry of vacuum pump; When the vacuum pump work, make the interior attraction rifle that produces of dirt bottle of sealing attract the required negative pressure of dirt,, wait the interior dirt of dirt bottle after long-pending expiring by attracting rifle that patient's pus and blood, secretions on one's body is attracted in the dirt bottle, can only extract bottle stopper, with manually toppling over and cleaning, installation resets again, and so not only dismounting is loaded down with trivial details, but operator directly contact dirt, the health that is unfavorable for operator, the labor intensity of cleaning is big, and efficient is low.

The purpose of this utility model is to provide a kind of medical suction pump that can carry out automatic pollution discharge to the dirt in the dirt bottle.

This utility model purpose realizes by following technical measures: it comprises vacuum pump and dirt bottle, sealing of dirt bottle is inserted with dirt sucking tube and negative pressure suction tube, negative pressure suction tube is connected with the air entry of vacuum pump, also be inserted with blow-off pipe and just be pressed into trachea sealing of dirt bottle, just be pressed into trachea and be connected with the gas outlet of vacuum pump, blow-off pipe one end is inserted to the bottom of dirt bottle; Respectively be provided with the bilateral valve on described dirt sucking tube and the blow-off pipe, described negative pressure suction tube and just be pressed into trachea and respectively be provided with the two-position three way valve.

In use, earlier blow-off pipe with just be pressed into valve closing on the trachea, the valve opening on dirt sucking tube and the negative pressure suction tube is in the attraction duty at this moment, vacuum pump makes and produces negative pressure in the dirt bottle, and dirt sucking tube is attracted into dirt in the dirt bottle by attracting rifle; By the time after dirt amasss and completely arrives to a certain degree, again blow-off pipe with just be pressed into valve opening on the trachea, valve closing on dirt sucking tube and the negative pressure suction tube, be in the blowdown duty this moment, the high pressure gas of vacuum pump gas outlet enters the dirt bottle, makes the air pressure of remaining space in the dirt bottle become malleation by negative pressure, when this normal pressure is higher than external atmosphere pressure, dirt in the squeeze bottle is discharged outside the bottle by blow-off pipe rapidly.

Two position three-way valve described in the utility model and two-way valve are hand-operated valve or by the electromagnetic valve of circuit control.

Control circuit described in the utility model comprises control key, position sensor and single-chip microcomputer, control key links to each other with relative trigger signal input part on the single-chip microcomputer respectively with position sensor, and the control signal output ends of single-chip microcomputer links to each other with the corresponding solenoid valve control end; This position sensor is positioned at the dirt bottle.When the dirt liquid level touched pick off in the dirt bottle, pick off produced triggering signal, carries out intelligent blowdown by Single-chip Controlling; Dirt also can be by carrying out automatization's blowdown by control key at any time in the dirt bottle.

As to further improvement of the utility model, also comprise buffering dirt bottle, the described negative pressure suction tube that is connected in the vacuum pump air entry and is provided with two position three-way valve is inserted in this buffering dirt bottle, plugs the negative pressure inlet pipe in addition cushioning between dirt bottle and the dirt bottle; Buffering dirt bottle can prevent that when attracting dirt, dirt can cause the damage of vacuum pump like this in negative pressure suction tube sucks vacuum pump.

Because this utility model is pegged graft between vacuum pump gas outlet and dirt bottle and just is being pressed into trachea, by utilizing the high pressure gas of vacuum pump gas outlet, high pressure gas is entered the dirt bottle through just being pressed into trachea, make the air pressure of remaining space in the dirt bottle become malleation by negative pressure, thereby can be rapidly dirt outside blow-off pipe extruding bottle outlet, can directly enter sewer through the blow-off pipe outlet again, therefore need not with manually toppling over and cleaning the dirt bottle, also need not to carry out loaded down with trivial details dismounting, improve work efficiency greatly, kept the sanitation and hygiene of surrounding working environment; Additional valves can be controlled by single chip circuit, can realize automatization, intelligent blowdown like this, and is more convenient and practical.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is the pipeline structure sketch map of utility model;

Fig. 2 is the schematic diagram of control circuit.

As shown in Figure 1, present embodiment comprises vacuum pump 1, dirt bottle 2 gentle dirt removal thing bottles 13, sealing of dirt bottle 2 is inserted with dirt sucking tube 3, negative pressure suction tube 14, blow-off pipe 6 and just be pressed into trachea 7, dirt sucking tube 3 is connected to and attracts on the rifle, one end of blow-off pipe 6 is inserted to the bottom of dirt bottle 2, the other end can directly feed sewer, just being pressed into trachea 7 is connected with the gas outlet 8 of vacuum pump 1, the other end of negative pressure suction tube 14 inserts sealing of buffering dirt bottle 13, be inserted with negative pressure inlet pipe 4 in addition sealing of buffering dirt bottle 13, negative pressure suction tube 4 is connected with the air entry 5 of vacuum pump 1, buffering dirt bottle 13 can prevent when attracting dirt, dirt avoids causing the damage of vacuum pump in negative pressure suction tube sucks vacuum pump.On dirt sucking tube 3 and blow-off pipe 6, respectively be connected a manual

bilateral valve
