Abstract
The utility model discloses a central negative-pressure suction device which comprises a connecting pipe, a negative-pressure bottle, the negative-pressure suction device and a sterilized, closed and empty glass bottle. The central negative-pressure suction device is characterized in that air is continuously sucked under central negative pressure for vacuum pumping to keep the sterilized, closed and empty glass infusion bottle to be in a vacuum state, and when a puncture needle under negative pressure enters a pleural cavity, air or liquid in the pleural cavity flows into the sterilized, closed and empty glass infusion bottle under negative pressure. According to the objective indicator, whether the puncture needle enters the pleural cavity or not can be judged and the puncture needle is prevented from being inserted too deeply and damaging visceral organs. A syringe is not required to repetitively suck air because the operation is conducted in a closed state, the safety is improved, the negative pressure is moderate because the central negative pressure is approximately 0.03 to 0.04MPa, the diversion is smooth, the flow rate is constant, the probability of adverse reaction is small, the operation can be conducted by one person and the labor is saved.
Description
Technical field
This utility model relates to suction device, particularly a kind of central negative pressure suction device.
Background technology
Existing thoracentesis is a clinical diagnosis commonly used and therapeutic operating technology, the pleural space puncture method that tradition adopts is all from national institution of higher learning, the method that diagnostics's teaching material is introduced, this method has been used for many years, to diagnosed SARS case is successful, but for as hydrops in a small amount in the encapsulated effusion, the patient of obesity or pachynsis pleurae, adopt the success rate of traditional pleural space puncture method not high, and develop complications easily.
Summary of the invention
The purpose of this utility model is to provide a kind of central negative pressure suction device that utilizes, continues to attract, and extracting vacuum, the self-control Dewar bottle is applied to thoracentesis, obtains better clinical effectiveness.It mainly is to utilize central negative pressure to continue to attract, extracting vacuum, make the empty infusion bottle of sterilization be in vacuum negative pressure condition, when the puncture needle that is negative pressure enters pleural space, gas or liquid in it will flow to the Dewar bottle that is negative pressure, and negative pressure is moderate, and drain is unobstructed, constant flow rate, untoward reaction is few.
Technical solution of the present utility model is such: the confined air vial, the connection tube that comprise sterilization, negative pressure bottle, negative pressure suction device, it is characterized in that having second connection tube to be connected between this new pleural space puncture method apparatus and the traditional pleural space puncture method apparatus, the confined air vial of sterilization is connected with the vacuum suction bottle, the valve assembly of band vacuum meter is connected with negative pressure suction device, band tubing one end of two ends band injection needle is inserted in pleural space, and the other end is inserted in the confined air vial of sterilization.Second connection tube, one end is inserted in the confined air vial of sterilization, and the other end is inserted in the vacuum suction bottle.
First connection tube, one end is inserted in the vacuum suction bottle, the valve assembly of other end connecting band vacuum meter.
Negative pressure suction device connection tube one end is connected with the central negative pressure suction device, and the other end is connected with the valve assembly of band vacuum meter.
The utility model has the advantages that: utilize central negative pressure to continue to attract, extracting vacuum, make the empty infusion bottle of sterilization be in vacuum state, and when in the pleural space that a variety of causes causes during hydrops, it is for not existed at the property cavity, the intracavity negative pressure also disappears thereupon, and when in a single day the puncture needle that is negative pressure entered pleural space, gas or liquid in it can flow to the Dewar bottle that is negative pressure, operation is in sealing state, need not aspirate repeatedly with syringe, reduce the pleural space pollution, overcome that traditional thoracic-puncture needle only relies on patient's experience and feel is judged, avoid the safety of puncturing, central negative pressure is regulated about 003～004Mpa, and negative pressure is moderate, and drain is unobstructed, constant flow rate, untoward reaction is few, but the one man operation saves manpower.
Description of drawings
It is such that the novel structure of this reality constitutes:
Accompanying drawing is that overall structure of the present utility model is connected and installed the use sketch map.
In the accompanying drawing, the band tubing (6) of the valve assembly (2) of traditional pleural space puncture method apparatus (1), band vacuum meter, first connection tube (3), vacuum suction bottle (4), second connection tube (5), two ends band injection needle, this new pleural space puncture method apparatus (7), the confined air vial (8) of sterilization, negative pressure suction device connection tube (9), negative pressure suction device (10).
The specific embodiment
Most preferred embodiment of the present utility model is such: with reference to the preparation of accompanying drawing, material: be ready to the vacuum suction bottle, the confined air vial 500ML of sterilization, No. 12 band tubings of two ends band injection needle, negative pressure bottle and vial have sealing-plug, each bottle, the equal strict sterilization sterilization of pipe utensil.This utility model is by being connected with second connection tube (5) between the new pleural space puncture method apparatus (7) of traditional pleural space puncture method apparatus (1) and this, entering vacuum suction bottle (4) in the equipment that the liquid or the gas of pleural space is being negative pressure stores, can directly not overflow the outer pollution of bottle, but some little trace excessive and to enter the confined air vial (8) of sterilization no longer excessive as stocking, there is negative pressure suction device connection tube (9) to be connected between the valve assembly (2) of negative pressure suction device (10) and band vacuum meter, has first connection tube (3) of negative pressure suction device to be connected between the valve assembly (2) of being with vacuum meter and the vacuum suction bottle (4).Have second connection tube (5) to be connected between the confined air vial (8) of vacuum suction bottle (4) and sterilization, band tubing (6) one ends of two ends band injection needle insert the confined air vial (8) of sterilization, and the syringe needle of the other end enters patient's pleural space.Regulate negative pressure and be no more than 003～004Mpa, continue to attract evacuation.Concrete operations: the valve assembly (2) of vacuum suction bottle one end connecting band vacuum meter, the valve assembly (2) of band vacuum meter is connected with negative pressure suction device (10) again.The confined air vial (8) of another termination sterilization of vacuum suction bottle (4) is regulated negative pressure and is no more than 003～004Mpa, continues to attract evacuation, makes Dewar bottle; By traditional thoracentesis preparation, predetermined point of puncture skin routine disinfection local anesthesia; Band tubing (6) the one end syringe needles of clamping two ends band injection needle with pliers insert pleural space, and the other end inserts the confined air vial (8) of having made sterilization, and be negative pressure in the rubber tube this moment; By the predetermined slow inserting needle of inserting needle direction, open and have liquid or gas to splash into the confined air vial (8) of sterilization when the rubber tube that is negative pressure is multiple suddenly, illustrate that syringe needle enters pleural space, stop inserting needle, fix puncture needle and get final product.
