Abstract
The invention discloses a negative pressure drainage device with adjustable pressure and belongs to the field of medical equipment. The negative pressure drainage device comprises a liquid storage bottle, a drainage tube, a lock catch connector connecting an inner cavity of the liquid storage bottle and the drainage tube. The drainage tube is sequentially provided with a pressure gage and a pressure regulating valve along the liquid flowing direction. The drainage tube is further provided with a first reverse flow resistance device. A second reverse flow resistance device is disposed at the lock catch connector end in the liquid storage bottle. The liquid storage bottle is further provided with a vacuum indicator communicated with the inner cavity. By the aid of the negative pressure drainage device with adjustable pressure, the volume of liquid in the bottle can be measured precisely, the bottle body is small and light and easy to carry, and the problems of siphon or inadequate drainage caused by too high or too low a negative pressure value can be avoided when pressure is properly adjusted through a pressure adjusting valve. Meanwhile, pressure changes in the bottle can be directly observed through the vacuum indicator, and the risk of retrograde infection can be effectively removed under the action of the double reverse flow resistance devices.
Description
Technical field
The present invention relates to medical instruments field, relate in particular to the adjustable negative pressure drainage device of a kind of pressure.
Background technology
As far back as nineteen seventies, just there are many pieces of documents to explore difficult wound surface and the wound of healing of application of negative pressure treatment in the Soviet Union, just began to propose to treat with vacuum suction and surgical debridement the infective wound surface of suppuration in 1986, the negative pressure product also develops into present negative pressure drainage device by initial rubber tube drain.
Negative pressure drainage device is to utilize principle of negative pressure to extract the hematocele, hydrops etc. of patient's lesions position, promotes the medical apparatus and instruments that wound surface recovers, and clinical use product mainly contains negative pressure suction ball and negative pressure drainage vessel.Wherein the defective of negative pressure suction ball maximum is that negative pressure value is not enough, and drain is insufficient, and infecting often appears in the patient, heating paresthesia; And traditional negative pressure drainage vessel body is heavy, not portable, portioned product also needs allows manual aspiration to make and produces negative pressure in bottle, use inconvenience, and there are the shortcomings such as drain obstruction, drain be insufficient in the lower negative pressure drainage bottle when drain, and high negative pressure drainage bottle often complex structure, volume are large, the use initial stage due to bottle in negative pressure value excessive, easily cause siphon, even to muscle, tissue and organ injury, can not measure simultaneously the volume that flows into reservoir liquid, be unfavorable for clinical observation judgement Wound treating situation, limited the clinical use of product.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of adjustable negative pressure pressure, prevent the adjustable negative pressure drainage device of pressure of adverse current siphon.
Technical scheme: for achieving the above object, the adjustable negative pressure drainage device of a kind of pressure of the present invention comprises the snap close joint of liquid containing bottle, drainage tube, connection liquid containing bottle inner chamber and drainage tube, described drainage tube is provided with Pressure gauge and pressure regulator valve successively along liquid flow direction, also be provided with the first anti back-flow arrangement on described drainage tube, snap close tip side in described liquid containing bottle is provided with the second anti back-flow arrangement, and described liquid containing bottle also is provided with the vacuum indicator of communication with cavity.
Vacuum indicator of the present invention is the elastic bellows of inner hollow, accurately the situation of change of the reaction bulb internal pressure of image.
Described snap close joint is comprised of male female Luer and female female Luer.Public female Luer is connected with liquid containing bottle, and female female Luer is connected with drainage tube, male female Luer be connected rotatably tight connection of female Luer.
Be provided with the conduction hole of some group switching centre symmetries in described drainage tube.
Described liquid containing bottle lateral wall is provided with the measurement scale line for measurement volumes.As further optimization of the present invention, described liquid containing bottle lateral wall also is provided with the little measurement scale line that is 30 ~ 50 ° of angles with measurement scale line.But thereby how much realize the immediate observation drainage-fluid.
The first anti back-flow arrangement of the present invention and the second anti back-flow arrangement include but not limited to check valve or control the device of one-directional fluid flow.
Beneficial effect: but the adjustable interior liquid volume of negative pressure drainage device accurate measurement bottle of a kind of pressure of the present invention, bottle is light and handy, be easy to carry, and can be by the suitable adjust blood pressure of pressure regulator valve to avoid the too high or too low problems such as siphon or inadequate drainage that cause of negative pressure value, simultaneously can also pass through vacuum indicator direct observation pressure of the inside of a bottle situation of change, and under the effect of dual anti back-flow arrangement, can effectively eliminate the risk of retrograde infection.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1, the adjustable negative pressure drainage device of a kind of pressure of the present invention comprises: in have-80KPa ~-liquid containing bottle 1 of 98KPa negative pressure, drainage tube 2, connect the snap close joint 3 of liquid containing bottle 1 inner chamber and drainage tube 2, liquid containing bottle 1 has multiple volume specification, between 100mL ~ 2000mL, liquid containing bottle 1 lateral wall is provided with the measurement scale line 9 for measurement volumes, also be provided with near below liquid containing bottle 1 the little measurement scale line 10 that is 30 ~ 50 ° of angles with measurement scale line, liquid containing bottle bottle inclination measurement when facilitating drainage-fluid less is to reach the purpose that accurately measures.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
