Description
Technical field
This utility model relates to technical field of medical instruments, particularly a kind of portable negative pressure suction device.
Background technology
Pressure ulcer is a long-term bed patient common but severe complication, and it not only brings misery to the patient, and often because of severe infections, whole body depletion appear in obstinate, so that become the one of the main reasons that causes patient death.
At present, the pressure ulcer patient adopts vacuum suction machine or wall negative pressure and special-purpose material to carry out negative pressure wound therapy more, said method has the cost costliness, the shortcoming that inconvenience is moved, part patient as: out-patient, need mobile patient, the band wound surface patient etc. that leaves hospital, often have to adopt easy syringe to extract way even stop negative pressure treatment.
Summary of the invention
The purpose of this utility model provides a kind of portable negative pressure suction device, and the negative pressure that this suction device produces has pressure stability, adjustable in pressure, is convenient to connection, portable characteristics.
The technical scheme that its technical problem that solves this utility model adopts is: design a kind of portable negative pressure suction device, it comprises receiver, sealing-plug, connection tube, it is characterized in that: the upper opening place of receiver is fixed with seal cover, connection tube runs through seal cover and extends in the receiver, connection tube is positioned at the outer part of receiver and is connected with Pressure gauge by pressure-regulating valve, receiver is built-in with piston, the cross section of inboard wall of piston and receiver is complementary, be equipped with check valve on the piston, the lower end of piston is fixedly connected with piston push rod, piston push rod extends going to the bottom of receiver, and the receiver side lower part leaves waste liquid outlet.
Described seal cover is integrative-structure or the rubber seal plug with the receiver once injection moulding.
The front end of described connection tube is connected with three-way interface.
Be socketed with flow-stopping clip on the described connection tube.
The both sides of described receiver respectively are connected with a link, and cross-under has braces in the link.
Described waste liquid outlet is positioned at the bottom of receiver, and waste liquid outlet passes through plug seal.
The beneficial effects of the utility model are: this device can be controlled different negative pressure value by Pressure gauge on the connection tube and pressure-regulating valve according to the difference of patient's traumatic condition, make pressure stability conveniently regulate, simultaneously arranged link in the side of receiver, make this suction device more portable, produce negative pressure by piston, therefore under the situation that need not electric energy and wall negative pressure, can implement voluntarily, avoid the malpractice that causes because of power failure.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the structural representation of this utility model embodiment;
Fig. 2 is structural representation Fig. 2 of this utility model embodiment.
Among the figure: 1, receiver; 2, Pressure gauge; 3, pressure-regulating valve; 4, sealing-plug; 5, connection tube; 6, three-way interface; 7, check valve; 8, piston; 9, piston push rod; 10, waste liquid outlet; 11, stopper; 12, link; 13, braces; 14, flow-stopping clip.
The specific embodiment
As shown in Figure 1, provided the structural representation of the portable negative pressure suction device of this utility model embodiment, it comprises receiver 1, sealing-plug 4, connection tube 5; The plastic bottle that receiver 1 adopts, the upper opening sealing and fixing of receiver 1 has sealing-plug 4, sealing-plug 4 is integrative-structure or rubber seal plugs of once injection moulding, connection tube 5 runs through sealing-plug 4 and extends in the receiver 1, connection tube 5 is positioned at receiver 1 outer part and is connected with Pressure gauge 2 by pressure-regulating valve 3, thereby by regulating the negative pressure in the pressure-regulating valve 3 control receivers 1, receiver 1 is built-in with piston 8, the cross section of inboard wall of piston 8 and receiver 1 is complementary can slipper seal, be equipped with check valve 7 on the piston 8, check valve 7 can enter receiver 1 bottom with the air and the waste liquid on top, and can not oppositely flow into, its genus commercially available prod all is widely used in each field, at this its structure is not elaborated; The piston push rod 9 that the lower end of piston 8 is fixedly connected, piston push rod 9 extends going to the bottom of receiver 1, and piston push rod 9 carries out the slipper seal processing with the contact site that receiver 1 is gone to the bottom, and receiver 1 side lower part leaves waste liquid outlet 10.
During use, at first the front end with connection tube 5 is connected with patient's drainage tube, manually promote piston push rod 9 then, piston 8 moves to receiver 1 top, the air on receiver 1 top moves to receiver 1 bottom by the check valve on the piston 87, piston 8 by receiver 1 top when move in receiver 1 bottom, check valve 7 makes the air of bottom can't enter receiver 1 top, thereby negative pressure is formed at receiver 1 top, the partial slough of wound under the effect of negative pressure, secretions, antibacterials etc. are in connection tube 5 enters into receiver 1, and move to receiver 1 bottom from check valve 7, at last, waste liquid outlet 10 is opened, and the waste liquid of receiver 1 is poured out by the waste liquid outlet 10 of side lower part.
This device also can be according to the different adjustment of patient's traumatic condition different negative pressure value, the negative pressure value that produces in the receiver 1 can show by the Pressure gauge on the connection tube 52, also can control negative pressure value in the receiver 1 by regulating pressure-regulating valve 3 simultaneously.
As shown in Figure 2, present embodiment 2 is substantially the same manner as Example 1, and difference is that the front end of connection tube 5 is connected with three-way interface 6, and is socketed with flow-stopping clip 14 on the connection tube 5, the both sides of receiver 1 respectively are connected with a link 12, and cross-under has braces 13 in the link 12.
The waste liquid outlet 10 of present embodiment is positioned at the bottom of receiver 1, and waste liquid outlet 10 is by stopper 11 sealings, and the stopper 11 with waste liquid outlet 10 when toppling over pulls out, and the liquid in the receiver 1 is poured out by the waste liquid outlet 10 of receiver 1 bottom.
The three-way interface 6 that connection tube 5 front ends connect can be treated a patient's many places wound simultaneously, and each structure can both be connected with patient's drainage tube; Belled flow-stopping clip 14 can carry out snap close to connection tube 5 on the connection tube 5, thus the break-make of control connection pipe 5; The link 12 of receiver 1 sidepiece can make things convenient for carrying of patient, directly articulates link 12 when conveniently articulating and gets final product, and what be inconvenient to articulate also can upload the braces 13 that connects by link 12 and fix.
