Abstract
The utility model discloses a kind of thoracic cavity encapsulated effusion negative pressure suction device, comprise needle tubing and be placed on the needle cannula of its outside, described needle cannula end establishes a bayonet socket, and described needle tubing end establishes a needle stand; Also comprise syringe, negative pressure device and the drainage tube be connected with negative pressure device, described syringe front end access needle stand, described drainage tube other end connecting needle sleeve pipe bayonet socket.This utility model by needle tubing and be placed on its outside needle cannula puncture enter thoracic cavity, inject anaesthetic by syringe and needle tubing simultaneously, then only need to extract needle tubing, needle cannula indwelling is in thoracic cavity, again drainage tube is accessed needle tubing cover, can hydrops be extracted, need not first injecting anesthetic medicine, to puncture operation at twice again, alleviate patient suffering, and easy to operate.After puncture puts in place, first can extract hydrops in body slightly with syringe, the difference according to hydrops and blood judges that whether puncture position is correct, and can carry out position adjustment, avoids carrying out hydrops drain blindly.
Description
Technical field
this utility model relates to medical apparatus and instruments, particularly a kind of thoracic cavity encapsulated effusion negative pressure suction device.
Background technology
encapsulated intrathoracic fluid (encapsulated effusion) refers to that dirty, the parietal pleura of pleuritis patient stick together a certain position making hydrops be confined to pleural space, are more common in breast lower side posterior chest wall.Be generally repeatedly extract hydrothorax by puncture needle, the injections such as anaesthetic entered, repeatedly work after the hydrops in thoracic cavity has extracted, make troubles to patient on the one hand, on the other hand in extraction, the gas having other in the process of injection enters.
Utility model content
this utility model object is: provide the thoracic cavity encapsulated effusion negative pressure suction device that a kind of injecting anesthetic and drainage catheter indwelling integration are carried out.
the technical solution of the utility model is:
a kind of thoracic cavity encapsulated effusion negative pressure suction device, comprise needle tubing and be placed on the needle cannula of its outside, described needle cannula end establishes a bayonet socket, and described needle tubing end establishes a needle stand; Also comprise syringe, negative pressure device and the drainage tube be connected with negative pressure device, described syringe front end access needle stand, described drainage tube other end connecting needle sleeve pipe bayonet socket.
preferably, described needle cannula length is less than needle tubing length, and needle cannula length is 7-13cm, and internal diameter is 2mm.
preferred described needle tubing is hollow metal tube, and front end is tip-like.
preferably, described needle cannula is carved with scale.
relative to prior art, advantage of the present utility model has:
(1) the thoracic cavity encapsulated effusion negative pressure suction device that provides of this utility model, by needle tubing and be placed on its outside needle cannula puncture enter thoracic cavity, inject anaesthetic by syringe and needle tubing simultaneously, then only need to extract needle tubing, drainage tube in thoracic cavity, then is accessed needle tubing cover by needle cannula indwelling, hydrops can be extracted, need not first injecting anesthetic medicine, to puncture operation at twice again, alleviate patient suffering, and easy to operate.
(2) after this utility model puncture puts in place, first can extract hydrops in body slightly with syringe, the difference according to hydrops and blood judges that whether puncture position is correct, and can carry out position adjustment, avoids carrying out hydrops drain blindly.
Accompanying drawing explanation
below in conjunction with drawings and Examples, this utility model is further described:
fig. 1 is the schematic diagram that thoracic cavity described in the utility model encapsulated effusion negative pressure suction device connects syringe;
fig. 2 is the schematic diagram that thoracic cavity described in the utility model encapsulated effusion negative pressure suction device connects drainage tube and negative pressure device.
wherein, 1, needle tubing; 11, needle stand; 2, needle cannula; 21, bayonet socket; 3, syringe; 4, drainage tube; 5, negative pressure device.
Detailed description of the invention
embodiment:
understand technology contents of the present utility model for convenience of those skilled in the art, below in conjunction with embodiment, this utility model is described in further detail.
as illustrated in fig. 1 and 2, the thoracic cavity encapsulated effusion negative pressure suction device that this utility model discloses, comprise needle tubing 1 and be placed on the needle cannula 2 of its outside, needle cannula 2 length is 10cm, and internal diameter is 2mm, and needle cannula 2 is also carved with scale; Described needle tubing is the hollow metal tube storing liquid medicine, and front end is tip-like, stretches out needle cannula 2; Described needle cannula end establishes a bayonet socket 21, and described needle tubing end establishes a needle stand 11.
during concrete operations, as shown in Figure 1, the syringe 3 front end access needle stand 11 of anaesthetic will be housed, then insert in thoracic cavity by needle tubing 1 together with needle cannula 2, insertion depth, at about 3cm, carries out anaesthetic injection by syringe 3 simultaneously.And then extract liquid in body slightly with syringe 3, difference according to hydrops and blood judges that whether puncture position is correct, incorrect, carry out position adjustment, until the hydrops that syringe extracts is intrathoracic hydrops, finally extracted together with needle tubing 1 by syringe 3, needle cannula 2 is retained in thoracic cavity.As shown in Figure 2, drainage tube 4 is accessed the bayonet socket 21 of needle cannula, under the attraction of negative pressure device 6, extract intrathoracic hydrops.
above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All modifications done according to the spirit of this utility model main technical schemes, all should be encompassed within protection domain of the present utility model.
