Abstract

The utility model relates to a chest puncturing air exhausting needle, which fills the blank of no special puncturing needle in treating thoracic cavity pneumatosis in medical treatment fighting lines in the country. Because a regulating screw thread is arranged on a needle tube and a depth regulating plate, and a regulating clamp nut are matched with the needle tube, the aim that subcutaneous pneumatosis can not be caused by that the needle head can not slide into skin and injure re-spread lung and the out slide of the needle tube. The utility model has the advantages of simple structure and convenient operation, and can be independently achieved by doctors and nurses. When treating, the utility model has the advantages of less wound, no need of cutting skin in operation, no need of stitching, the chance of secondary infection reducing and the pain of patients in the process of medical treatment lightening.

Description

Exhausting needle for sternal puncture

This utility model belongs to a kind of special-purpose breast that uses in the medical industries and wears exhaust needle.

At present, intrathoracic cannula closed drainage or repeated localised puncture degassing method are generally adopted in state, inside and outside aerofluxus to aerothorax.The closed drainage complicated operation needs strict sterilization apparatus and specialist operation, and wound is bigger; And the repeated localised puncture aerofluxus, the patient is beyond affordability, and is painful big, and curative effect is not good enough.In recent years China has the people to try out No. 16 syringe needles (medical maximum syringe needle internal diameter is 1.2mm), directly puncture, backshank connects the water-sealed drainage bottle drain, but because the smooth no fixing point of needle tubing, most of needle tubing exposes to outside the skin, and backshank is heavier in addition, is fixedly made troubles, even temporary transient fixing, also easily cause because of patient's activity or respiratory movement: syringe needle slips into the multiple lungs of opening of damage; Syringe needle skids off and causes subcutaneous emphysema, all can make the aerofluxus failure.

The purpose of this utility model is to avoid above-described weak point, and provides a kind of simple in structure, and is easy to operate, can treat a kind of special-purpose breast of aerothorax fast and wear exhaust needle.

This utility model is finished by following approach:

Breast is worn exhaust needle and is made of needle tubing, depth adjustment dish and adjusting clamp nut etc.; The first half at needle tubing is processed with the adjusting screw thread, regulates the screw thread bottom depth adjustment dish of adapted with it is housed, and regulates screw thread top the adjusting clamp nut of adapted with it is housed; The needle tubing upper end is provided with the backshank of international standard type.

Accompanying drawing is this utility model master pseudosection:

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

Breast is worn the use of exhaust needle: when patient's local anesthesia, adopt the negative pressure method of needle insertion, in case negative pressure disappears, the proof syringe needle enters the thoracic cavity, can transfer to the local anaesthesia pin, and record depth of needle (this degree of depth is the actual thoracic wall thickness that patient's breast is worn release), adjust and be located at the depth adjustment dish (3) that the adjusting screw thread (5) on the needle tubing (4) matches then, the actual thoracic wall thickness that makes it to wear with this patient's breast release conforms to, immediately breast is worn exhaust needle and vertically thrust skin, the disk end face of depth adjustment dish (3) lower end is closely contacted with skin, clamp nut (2) is regulated in rotation, makes it to link to each other with the other end of the disc face of depth adjustment dish (3), plays constant depth adjustment disk (3), at this moment syringe needle spacing because of depth adjustment dish (3) disk, can not continue to slip in the skin, the multiple lungs of opening of damage are simultaneously with disk and the skin adhesive of adhesive plaster with adjustment disk (3), reach the not outer purpose that slips into of needle tubing, can reach the deflated purpose in thoracic cavity like this.

This breast is worn exhaust needle and can all be adopted stainless steel material to make; Alleviate overall weight and the disposable purpose that breast is worn exhaust needle for reaching, lightweight materials such as regulating clamp nut (2), depth adjustment dish (3) employing plastics can be made.

The utility model major advantage: 1, this apparatus structure is simple, and is easy to operate, but the equal complete independently of doctor, nurse, especially in emergency with do not possess under the closed drainage condition rapidly relief of symptoms, rescue life; 2, use this device treatment wound little, because need not surgical incision skin, need not to sew up, reduced the scabies secondary infection chance, alleviated the misery of patient in treatment; 3, to amassing narrow-minded need not the be patient of closed drainage and the elderly and infirm of PFT difference, rapidly exhaust improves symptom; 4, this device depth adjustment dish (3) can be regulated arbitrarily between 6.0～22mm, and this adjustable range is applicable to the wall of the chest thickness of Chinese thoracic cavity release; 5, the needle tubing internal diameter of this device reaches 1.6mm(greater than No. 16 syringe needle internal diameters), avoid secretion to stop up needle tubing, thereby effectively guaranteed smooth gas discharge; 6, this device has been filled up on China's medical treatment battle line and has been treated the blank that aerothorax does not have puncturing needle special.

Claims

1, a kind of breast is worn exhaust needle, it is characterized in that needle tubing (4) top is provided with adjusting screw thread (5), and the depth adjustment dish (3) of adapted with it is equipped with in the bottom of regulating screw thread, and the needle tubing upper end is provided with the backshank (1) of international standard type.

2, breast according to claim 1 is worn exhaust needle, it is characterized in that regulating screw thread (5) top the solid nut (2) of adjusting spiral shell of adapted with it is housed.
