Referring to fig. 1, the present embodiment provides a pneumothorax needle device, including: a vial 10, a sealing cap 20, a puncture needle 30, and a compressible balloon 40; a hollow channel is formed in the puncture needle 30 along the length direction, an anesthetic is injected in the hollow channel, one end of the puncture needle 30 is connected to the sealing cover 20, and a rubber plug 31 is arranged at one end of the hollow channel close to the sealing cover 20 and used for controlling the anesthetic to be discharged from the hollow channel; the bottle body 10 is filled with sterilized water, the sealing cover 20 can be screwed together with the bottle body 10, and the puncture needle 30 is immersed in the sterilized water; the compressible balloon 40 has a compressed state and an inflated state, the compressible balloon 40 covers the puncture needle 30 in the compressed state; in the inflated state, the compressible bladder 40 forms a lumen channel 43, and a one-way valve structure 42 is formed in the lumen channel 43 for controlling the one-way flow of gas in the chest cavity to the outside air. After the puncture needle 30 reaches the designated position, the puncture needle 30 can be pulled out, at this time, the puncture needle 30 is separated from the compressible air bag 40, and the lumen channel 43 formed by the compressible air bag 40 in the filling state is the position of the original puncture needle 30.
Local anesthesia is used during puncture, the anesthesia is extruded into the needle body by extruding the rubber plug on the sealing cover 20, and the anesthesia flows out, so that the complicated processes of on-site extraction and injection of the anesthesia are replaced, and the treatment is started quickly; after the puncture is successful, gas flows out from the opening of the anesthetic rubber plug 31 or the rubber plug 31 floats upwards to indicate that the puncture is in place, then the puncture needle 30 is pulled out and the compressible air bag 40 is inflated to achieve the filling state after the puncture is completed by 0.5 cm. At this time, a lumen channel 43 connecting the interior and the exterior is formed, which ensures that the gas in the thoracic cavity can be drawn out against the pressure without the external air being sucked into the thoracic cavity under the control of the check valve structure 42. The structure of the one-way valve 42 can be two, which are respectively arranged at the positions close to the two ends of the tube cavity channel 43, thereby achieving the effect of increasing the one-way flow safety of the gas in the thoracic cavity of the patient.
Through above-mentioned technical scheme, only can realize fast through this pneumothorax needle device: a series of operations related to closed thoracic drainage, such as disinfection, local anesthetic injection, puncture and the like, improve the efficiency of the operation, and are particularly suitable for emergency treatment; the device can be operated by a single person, is convenient to carry, is suitable for emergency treatment under various conditions, and gets rid of the complicated steps and conditions of the traditional surgical operation.
The open pneumothorax is easy to diagnose, and once the open pneumothorax is discovered, emergency treatment is required immediately, the chest wall wound is closed as soon as possible, and the open pneumothorax is changed into a closed pneumothorax. The emergency treatment generally uses a large first-aid kit of multi-layer cleaning cloth or thick gauze pad, if a large piece of Vaseline gauze or sterile plastic cloth is used more commonly, or clothes and bowls require the sealing dressing to be thick enough to avoid air leakage, but the sealing dressing cannot be stuffed into the wound. In order to improve the operation efficiency of the open pneumothorax, the outside of the bottle body 10 is wrapped with a double-sided adhesive sealing film 50 for closing the chest wall wound. One side of seal membrane 50 is glued in the bottle 10 outside, and as shown in figure 3 after the expansion, the another side of seal membrane 50 occupies the dust-proof membrane, tears the dust-proof membrane, alright paste seal membrane 50 at the corresponding skin surface of human body to the completion becomes closed pneumothorax with open pneumothorax, and this operation is safe accurate moreover, can not lead to the pressurization to wrap scheduling problem not tight because of the misoperation. The closed pneumothorax can be quickly changed into the closed pneumothorax through the sealing film 50, is suitable for various emergency situations, controls the state of an illness in time and reduces lung injury of a patient.
Further, the compressible air bag 40 is butterfly-shaped in the inflated state, which can be combined with fig. 2 specifically, and the compressible air bag 40 in the inflated state is formed with protrusions at two ends and has an elongated structure in the middle. The outer side of the compressible air bag 40 increases the tightness of the channel of the chest wall, the cleanness of the operation incision is ensured, and the inner side of the compressible air bag 40 isolates the port at the inner side of the channel from the lung tissue, so that the injury is reduced.
The outer side of the sealing cover 20 is provided with a depth control structure 21, and the depth control structure 21 is annular. Generally, the needle head is preferably 0.5-1.0 cm far into the thoracic cavity, and the depth of puncture can be controlled through the depth control structure 21, so that an objective index is provided for judging whether the thoracentesis needle enters the pleural cavity, the defect that the traditional thoracentesis needle is judged only by the experience and hand feeling of an operator is overcome, the damage to organs caused by the fact that the puncture needle enters too deep is avoided, the fixation of instruments in the treatment process is facilitated, unnecessary damage caused by too deep or too shallow is reduced, and the puncture success rate and the puncture safety are improved.
Further, the puncture needle 30 is connected with the sealing cover 20 by a thread structure, and the puncture needle 30 is connected at the center of the sealing cover 20. The piercing needle 30 penetrates the sealing cap 20 and exposes the rubber plug 31 to the top of the sealing cap 20 so as to squeeze the rubber plug 31.
In order to rapidly inflate the compressible air bag 40, the compressible air bag 40 can be inflated by means of the puncture needle 30, and specifically, referring to fig. 5, the pneumothorax needle device further comprises a thrust handle 32, wherein the thrust handle 32 is detachably connected with the rubber plug 31 and is used for pushing the rubber plug 31 to slide in the hollow channel, so that the compressible air bag 40 can be inflated by means of the puncture needle 30. When the compressible air bag 40 is not inflated, the push handle 32 and the rubber plug 31 can be separated, and after the push handle 32 is removed, as shown in fig. 4.
