Abstract

The utility model discloses an expansion type double-cavity puncturing drain needle. In the utility model, the upper part of the utility model is a drain pipe of which the inner part is provided with a washing pipe; the lower part of the utility model is a separating needle; the middle of the utility model is a guide block. When the separating needle punctures in the skin of patients and enters thoracic cavities, the rotating drain pipe enters thoracic cavities by the guide block, pushes aside the separating needle and carries out drain emergency treatment for pneumohemothorax patients or carries out washing or put therapeutic medicine. The utility model has passive state separation, has the advantages of small wound of human body tissue, easy wound healing, simple operation and easy emergency and is an ideal device for the emergency treatment and thoracic cavity closed tyoe draining of pneumohemothorax patients.

Description

Expansion type two-chamber puncture drainage needle

This utility model relates to a kind of apparatus that is suitable for pneumohemothorax first aid and closed drainage of pleural cavity.

At present, during to pneumohemothorax first aid and closed drainage of pleural cavity, must undergo surgery after the local anaesthesia, fill in sebific duct then and carry out drain.This method wound is bigger, and inconvenient fixedly drainage tube, and also inconvenience is washed with medicine and inserted.

The purpose of this utility model is at above-mentioned deficiency to pneumohemothorax first aid and closed drainage of pleural cavity, to provide a kind of two-chamber puncture drainage needle.

The purpose of this utility model is to realize like this, the drainage tube upper end is a rubber hose coupling, and the rubber hose coupling bottom is rotary handle fixedly, and external screw thread is arranged at the rotary handle bottom, and match with the female thread of guide pad, the guide pad both sides are fixed a fixed handle respectively, separate pin top in a tubular form and be wrapped on the guide pad, separate the pin bottom and evenly are divided into three lobes and are conical, drainage tube internal fixation scavenge pipe, the scavenge pipe lower end flushes with the drainage tube lower end, and stretch out from a side of drainage tube the upper end, and add seal cover.

The good effect that this utility model produced: can under the perspective state, accurately locate; The expansion type puncture belongs to passivity and separates, and wound is little; Drain can be carried out in one chamber, and another chamber can be cleaned or carry out medicine and insert, and can carry out simultaneously; Simple to operate, be convenient to first aid.

This utility model will be described further in conjunction with the accompanying drawings:

Fig. 1 is a structure cutaway view of the present utility model.

Drainage tube 4 upper ends are rubber hose couplings 1, and the rubber hose coupling bottom is fixed with rotary handle 2, and external screw thread is arranged at the rotary handle bottom, and match with the female thread of guide pad 5, and both sides are fixed a fixed handle 6 respectively on the guide pad 5.Separating pin 7 tops is wrapped on the guide pad 5 in a tubular form; Separation pin bottom evenly is divided into three lobes and is conical, drainage tube 4 internal fixation scavenge pipes 3, and the scavenge pipe lower end flushes with drainage tube 4 lower ends, and stretch out from a side of drainage tube 4 upper end, and add seal cover.

During use, hold guide pad 5 and fixed handle 6, aim at the drain position, patient's body lumen is thrust at the tip of separating pin 7, when making fixed handle 6 press close to skin, proficiency fixed guide piece 5, rotate rotary handle 2 on the other hand, make drainage tube 4 enter the patient thoracic cavity by guide pad 5 and will separate pin 7 separation, drainage tube 4 upper end rubber hose couplings 1 place puts on sebific duct, and the intrathoracic pus and blood gas of patient etc. is excreted.When needing cleaning or placement in the treatment medicine, can operate, finish the available adhesive tape in back fixed handle 6 is fixed on the patient skin by scavenge pipe 3.
