Abstract
The utility model relates to a medical appliance, particularly a disposable thorax puncture device. The utility model mainly solves the existing problems of puncturing and draining chests at present. The utility model comprises a needle head, wherein a syringe is connected to a needle handle of the needle head through a communicating pipe. The utility model is characterized in that a three-way valve is arranged on the communicating pipe between the needle head and the syringe, and the three-way valve is respectively connected with the needle head, the syringe and an output pipe; the output pipe is communicated with a drainage bag with a plugcock type valve at the bottom end, and scales are arranged on the needle head. The utility model has the advantages of good tightness, no pollution, high accuracy and simple operation, and is suitable for puncturing and draining thoraxes.
Description
Affiliated field
This utility model relates to a kind of medical apparatus and instruments, is specially disposable thoracentesis device.
Background technology
Traditional thoracentesis device of past mainly contains puncture needle, drain pipe clamp, vascular forceps composition.Its shortcoming is a thoracentesis inconvenient operation, loaded down with trivial details, the inserting needle depth easily takes place in the operating process to be difficult to grasp, the easy damaged lungs cause bleeding or pneumothorax, and in the drawing liquid process, easily leak gas, air inlet, even more serious is the hydrothorax such as the random discharging of extracting out, very easily causes environmental pollution and cross infection.
Summary of the invention
The purpose of this utility model is a kind of good leak tightness, disposable thoracentesis device pollution-free, easy and simple to handle.
The technical solution of the utility model is: this disposable thoracentesis device, comprise that syringe needle, syringe are by on the needle handle that is connected syringe needle communicating pipe, it is characterized in that, be provided with three-way valve on the communicating pipe between syringe needle and the syringe, this three-way valve connects syringe needle, syringe, outlet tube respectively; Described outlet tube is communicated with the drainage bag of bottom band plug valve; Described syringe needle is provided with scale.
In order to prevent hydrops backflow thoracic cavity, on the communicating pipe between syringe needle and the three-way valve, to be provided with the roller type infusion regulator.
The beneficial effects of the utility model are:
The first, total enclosing, airtight device can be avoided gas leakage, air inlet effectively fully, in order to avoid the people is for causing pneumothorax.
The second, accuracy, the difference of this puncture needle and conventional needle be, pin has scale can very accurate control depth of needle, is particularly determining more can embody its accurate, controlled, easy-operating advantage under the situation of depth of needle through the ultrasound diagnosis location.
Three, no dirt, the disposable use of this thoracentesis device, the puncture refuse is realized totally-enclosed processing, effectively avoids hospital's sexually transmitted disease (STD) such as environmental pollution and cross infection.
Four, operation convenience.Singlely can finish thoracentesis work.
Description of drawings
Figure is a structural representation of the present utility model.
Among the figure; 1. syringe needle, 2. communicating pipe, 3. roller type infusion regulator, 4. three-way valve, 5. syringe, 6. outlet tube, 7. drainage bag, 8. plug valve, 9. needle handle.
The specific embodiment
As figure.
Disposable thoracentesis device mainly contains and is with graduated piercing needle 1, connection tube 2, roller type infusion regulator 3, three-way valve 4, syringe 5, outlet tube 6, drainage bag 7, plug valve 8 to form.
Syringe needle 1 is connected with communicating pipe 2 by needle handle 9, is provided with three-way valve 4 on the communicating pipe 2 between syringe needle 1 and the syringe 5, and this three-way valve 4 connects syringe needle 1, syringe 5, outlet tube 6 respectively.Described outlet tube 6 is communicated with the drainage bag 7 of bottom band plug valve.Described syringe needle 1 is provided with scale, also can be provided with scale on the drainage bag 7.
Each parts adopts disposable medical material commonly used.
During use, can hand needle handle 9 syringe needle 1 is thrust the thoracic cavity, because the B ultrasonic location is arranged in advance, there is centimeter scale (to amount to 10 centimeter length on the syringe needle 1 again, every centimetre of high range, every millimeter down scale), can control insertion depth fast and accurately, effectively avoid malpractice according to the remainder scale.After insertion work is finished, can utilize 50ml syringe 5 to extract hydrothorax, once unclean as if taking out, can syringe 5 and drainage bag 7 be communicated three-way valve 4 half-twists, pushing syringe 5 injects drainage bag 7 with the liquid of extracting out, after shifting the end onto,, carry out the operation second time then again 90 ° of three-way valve cycles, repeat said process, till patient's hydrothorax is pumped.
The hydrops of extracting out can be connected on test tube plug valve 8 bottoms if need chemical examination, rotates 90 ° on this valve, with hands extruding drainage bag 7, can take out the hydrops that needs.
State shown in the figure, three-way valve 4 make piercing needle 1 communicate with syringe 5, and drainage bag 7 is closed.
Under the state shown in the figure, three-way valve 4 turns clockwise 90 °, and syringe 5 communicates with drainage bag 7, and needle end is closed.
In order to prevent that three-way valve 4 is not tight, mistake is injected go back to the thoracic cavity with the hydrops of gas or extraction, is provided with roller type infusion regulator 3 on the communicating pipe between syringe needle 1 and the three-way valve 4.Before the hydrops in the syringe 5 having been pushed the drainage bag action, earlier infusion regulator 3 asphyxias by external pressure on the chest and abdomen, make communicating pipes 2 sealing at syringe needle 1 place, make operation safe, reliable.
Claims (2)
1, disposable thoracentesis device, comprise that syringe needle, syringe are by on the needle handle that is connected syringe needle communicating pipe, it is characterized in that be provided with three-way valve on the communicating pipe between syringe needle and the syringe, this three-way valve connects syringe needle, syringe, outlet tube respectively; Described outlet tube is communicated with the drainage bag of bottom band plug valve; Described syringe needle is provided with scale.
2, disposable thoracentesis device according to claim 1 is characterized in that the communicating pipe between syringe needle and the three-way valve is provided with the roller type infusion regulator.
