Abstract
The invention discloses a coreless pneumothorax puncture needle with low possibility of slipping and convenience for use. The coreless pneumothorax puncture needle comprises a drainage tube and a puncture needle matched with the drainage tube mutually, wherein the drainage tube structurally comprises a tube body, a head part, a drainage hole, a drainage channel, an airbag channel and an airbag, wherein the head and the drainage hole are arranged at one end of the tube body; the drainage channel is arranged in the tube body and is communicated with the drainage hole; the airbag channel is arranged at the outer side of the drainage channel in the tube body; the airbag is arranged in the tube body and is communicated with the airbag channel; the puncture needle structurally comprises a semicircular needle body and a needle head arranged at one end of the semicircular needle body; and a cavity which is mutually matched with the tube body of the drainage tube is arranged in the semicircular needle body. The invention has the advantages that the coreless pneumothorax puncture needle is applied to drainage of clinical aerothorax and pleural effusion and is suitable for popularization and application in basic hospitals and has a simple structure, convenience for use, low possibility of slipping and low manufacturing cost.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, relate in particular to a kind of centreless thoracentesis needle.
Background technology
Old spontaneous pneumothorax is one of clinical common emergency treatment, and pneumothorax is the disease of a kind of serious breathing and blood circulation, and this disease morbidity is unexpected, does not have obvious inducement more, and the diagnosis and treatment of condition of illness severe patient are untimely to cause patient respiratory, circulatory failure causing death.Wound also can cause pneumothorax, hemothorax, infects then to cause empyema easily, and pneumothorax can cause pneumatosis in the thoracic cavity, and hemothorax and empyema can cause hydrothorax.One of a kind of basic skills of treating aerothorax, hydrops of closed drainage of pleural cavity technology during treatment, is cut an osculum earlier on illing skin; Use the trocar to be inserted in patient's the thoracic cavity, the existing trocar has been provided with nook closing member, cooperates drainage tube to carry out drain; Drainage tube is prone to slippage; The length of inserting the thoracic cavity inner drainage tube is not easy control, and drainage tube is prone to give a discount, and drainage effect is bad.
Summary of the invention
Technical problem to be solved by this invention is: a kind of slippage, centreless thoracentesis needle easy to use of being difficult for is provided.
In order to solve the problems of the technologies described above; The technical scheme that the present invention adopts is: the centreless thoracentesis needle; Comprise: drainage tube and the puncture needle that cooperatively interacts with drainage tube, the structure of said drainage tube comprises: body, be arranged on body one end head and conduction hole, be arranged on the drainage channel that is connected with conduction hole in the body, be arranged on the air bag passage in the drainage channel outside in the body and be arranged on the interior air bag that is connected with the air bag passage of body; The structure of said puncture needle comprises: the semicircle needle body be arranged on the syringe needle of semicircle needle body one end, be provided with the cavity that the body with said drainage tube cooperatively interacts in the semicircle needle body.
In order to solve the problems of the technologies described above better, the further technical scheme that the present invention adopts is: the other end at said semicircle needle body is provided with handle.
In order to solve the problems of the technologies described above better, the further technical scheme that the present invention adopts is: in said body, also be provided with irrigation channel between drainage channel and the air bag passage, an end of irrigation channel is connected with conduction hole.
Advantage of the present invention is: above-mentioned centreless thoracentesis needle, be applied to the drain of clinical aerothorax, hydrops, and simple in structure, easy to use, be difficult for slippage, low cost of manufacture is applicable to the promotion and application of basic hospital.

Among the figure: 1, body, 2, head, 3, conduction hole, 4, drainage channel, 5, the air bag passage, 6, air bag, 7, the semicircle needle body, 8, syringe needle, 9, cavity, 10, handle, 11, irrigation channel.
The specific embodiment
Describe particular content of the present invention in detail below in conjunction with accompanying drawing and specific embodiment.
Like Fig. 1, Fig. 2, shown in Figure 3; The centreless thoracentesis needle; Comprise: drainage tube and the puncture needle that cooperatively interacts with drainage tube; As shown in Figure 1, the structure of said drainage tube comprises: body 1, the head 2 that is arranged on body 1 one ends and conduction hole 3, be arranged on the drainage channel 4 that is connected with conduction hole 3 in the body 1, be arranged on the air bag passage 5 in drainage channel 4 outsides in the body 1 and be arranged on the body 1 interior air bag 6 that is connected with air bag passage 5; Like Fig. 2, shown in Figure 3, the structure of said puncture needle comprises: semicircle needle body 7 and the syringe needle 8 that is arranged on semicircle needle body 7 one ends are provided with the cavity 9 that the body 1 with said drainage tube cooperatively interacts in the semicircle needle body 7.
Like Fig. 2, shown in Figure 3, in the present embodiment, be provided with handle 10 at the other end of said semicircle needle body 7.
As shown in Figure 1, in the present embodiment, in said body 1, also be provided with irrigation channel 11 between drainage channel 4 and the air bag passage 5, an end of irrigation channel 11 is connected with conduction hole 3.
Use above-mentioned centreless thoracentesis to aerothorax, when hydrops carries out drain, on illing skin, cut an osculum earlier, utilize puncture needle to be inserted in patient's the thoracic cavity; Extract needle body, drainage tube is kept somewhere the thoracic cavity, inflates through 5 pairs of air bags 6 of air bag passage; After air bag 6 inflations, can well drainage tube be fixed in the thoracic cavity, fixed; Be difficult for slippage, and cutting part is stopped up, prevent that ambient atmos from getting into the thoracic cavity; Reduce subcutaneous emphysema simultaneously and take place, exempt sutured, reduce the patient suffering; Intrathoracic gas or liquid enter into drainage channel 4 through conduction hole 3 and carry out effective drainage, can wash drainage channel 4 through swash of wave passage 11, and it is unobstructed to keep clean.Can easily puncture needle be penetrated or extract in patient's the body through handle 10, simple in structure, easy to use.
