Abstract
Pressure volume measurement anti -drop negative pressure drainage device relates to medical instrument's technical field, including negative -pressure ball, sets up the spring steel ring in negative -pressure ball, sets up discharge orifice and connecting hole on negative -pressure ball, discharge orifice connecting pin, and the stomach tube is connected to the connecting hole, negative -pressure ball's surface sets up pressure sign and volume sign along the direction of height. The utility model discloses to negative pressure drainage device inner spring steel ring mark pressure and volume sign when length is stretched out and drawn back to the difference, the fine -grained management drainage ware of being convenient for.
Description
Technical field
This utility model relates to the technical field of medical apparatus and instruments, the structure of the depression drainage device used when being especially applied to clinical gastrointestinal decompression.
Background technology
Disorder in patients undergoing general surgical operations or intestinal obstruction patient often need gastrointestinal decompression, and per nasal places stomach tube.Depression drainage device connects stomach tube and plays sucking action.Current drainage device is of a great variety, and some drainage effects are not good enough, and what have does not have labelling volume index, can not measure, but all not have pressure flag, carries out pressure adjustment.Often accurate not to the regulation and control of negative pressure, lacked and do not had drainage, many can damage gastrointestinal tract mucously causes mucosal bleeding.In addition, the one end connecting stomach tube often causes coming off with stomach tube because of suction pump gravity.
Normal practice: part is measured after pouring measuring cup into without drainage-fluid in the suction pump of volume index again, and the adjustment only armrest sense to pressure, cannot accurately control.Connect and connect near adapter of plastic.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of can the P-V metering slip-off preventing depression drainage device of accurate measurement.
The purpose of this utility model is achieved in that P-V metering slip-off preventing depression drainage device, and comprise negative pressure ball, in negative pressure ball, arrange steel rim of spring, negative pressure ball arranges discharge orifice and connecting hole, discharge orifice connects stopper, and connecting hole connects stomach tube; At the outer surface of described negative pressure ball, pressure mark and volumetric marks are set along short transverse.
This utility model in different collapsing length tense marker pressure and volumetric marks, is convenient to fine-grained management drainage device to depression drainage device inner spring steel ring.
As improvement of the present utility model, the connecting hole of described negative pressure ball connects rubber pipeline, and rubber pipeline arranges actuator, and the other end of rubber pipeline is connected with described stomach tube by joint; Described actuator is connected and fixed card by connection tube, and fixing card is stuck on stomach tube.Stomach tube and depression drainage device is not easily made to come off, actuator adjustable size or switch.This product only supplies single use, directly throws in yellow refuse bag with rear, and clean, health, can not cause cross infection.
Clinical advantage:
1, metering drainage amount is conducive to;
2, the negative pressure of remaining valid is conducive to by accurate pressure measurement;
3, in accurate range of negative pressure, protect patient gastrointestinal tract mucous can not be damaged because negative pressure is excessive hemorrhage;
4, depression drainage device can be fixed on stomach tube, be unlikely to come off;
5, the fine-grained management of medical personnel to patient is convenient to.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the structural representation that this utility model removes steel rim of spring.
Detailed description of the invention
As shown in Figure 1, 2, P-V metering slip-off preventing depression drainage device, comprises negative pressure ball 10, arranges steel rim of spring 11 in negative pressure ball 10, arranges pressure mark 13 and volumetric marks 12 at the outer surface of negative pressure ball 10 along short transverse.Negative pressure ball 10 arranges discharge orifice 9 and connecting hole 7, and discharge orifice 9 connects stopper 8, and connecting hole 7 connects rubber pipeline 5, and rubber pipeline 5 arranges actuator 6, and the other end of rubber pipeline 5 passes through joint 4 and is connected stomach tube 1.Actuator 6 is connected and fixed card 2 by connection tube 3, and fixing card 2 is stuck on stomach tube 1.
