CN201235105Y - Casing tube type safety thoracic-puncture emergency treatment needle for tension pneumothorax - Google Patents

Abstract

The utility model discloses a pressure pneumothorax bushing-type safe thoracic-puncture first-aid needle, which comprises a needle bat (1), a syringe needle (2) and a needle stand (3). The utility model is characterized in that a thin-film tubular one-way valve (5) is arranged in the cavity of the needle stand (3), a rubber cannula (6) is sleeved on the needle bat (1), the seat end of the rubber cannula (6) is fixed on a rubber disk (7), the rubber disk (7) rotates on the outer wall of the needle stand (3) through a fixed turnbuckle (8), and the lower lateral surface of the rubber disk (7) is provided with an analgesic plaster layer (9). Since the thin-film tubular one-way valve is arranged in the needle stand, and therefore, pressure load can not be endured in the thoracic cavity, since the rubber cannula arranged in the thoracic cavity is a flexible pipe, and therefore, the internal organs can not be stabbed since air in the pneumatothorax is reduced or the pneumatothorax is contracted when in breathing, and meanwhile, analgesic plaster is further added to diminish the inflammation and reduce the pain, pain caused by piercing can be lightened, and therefore, the use is more safe, and the pressure pneumothorax bushing-type safe thoracic-puncture first-aid needle can be widely used in the emergency treatment of pressure pneumothorax.

Description

Tension pneumothorax casing type safety breast is worn Emergency Needle

Technical field

This utility model relates to the improvement that a kind of breast is worn Emergency Needle, and specifically a kind of tension pneumothorax casing type safety breast that is used for tension pneumothorax rescue usefulness is worn Emergency Needle.

Background technology

Tension pneumothorax is the emergency case that often runs in clinical, if untimely processing meeting threat to life immediately.Clinically, emergency case to tension pneumothorax is handled, both intrathoracic gas can be in time discharged in requirement, avoided the thoracic cavity internal gas pressure too high, promoted the strong then lung of diaphragm, compressing heart and compression, cause the respiratory and circulatory function disorder, threat to life, the body ambient atmos when air-breathing of asking for help again can not enter the thoracic cavity, forms open pneumothorax, cause in the thoracic cavity or wound infection, or make and hinder the atrophy of side lung.But still there is not special-purpose emergency equipment in rescuing clinically at present, what adopt usually is the 18-20 syringe needle, tie up altex glove outward, discharge intrathoracic gases at high pressure with puncture, and prevent that ambient atmos sucks in the thoracic cavity when air-breathing, therefore, the deficiency of tying up the method existence of altex glove with common 18-20 pin outward is: 1, poor stability, and also unreliable; 2, when rescuing, need interim the making, waste time and energy, incur loss through delay emergency time.In order to overcome the deficiency of above technology, what have has set up the flexure strip check valve in needle stand, when being higher than the elastic force sum of ambient pressure and flexure strip, intrathoracic gases at high pressure just can emit gas, when air-breathing, the air vent of flexure strip shutoff needle stand, obviously, the shortcoming of this Emergency Needle is that certain bearing capacity that is higher than ambient pressure must be arranged in the thoracic cavity.In addition, above technology also has a deficiency, exactly in the thoracic cavity gas emit that chest can progressively shrink in the process, if the untimely adjustment of syringe needle, then syringe needle can be stabbed internal organs.

Summary of the invention

The purpose of this utility model is to provide a kind of can prevent that when air-breathing, ambient atmos enters in the thoracic cavity, does not increase the intrathoracic pressure that bears again, but also can not wear Emergency Needle because of the tension pneumothorax casing type safety breast that internal organs are stabbed in the minimizing of gas in the thoracic cavity.

For reaching above purpose, the technical scheme that this utility model adopted is: this tension pneumothorax casing type safety breast is worn Emergency Needle, by needle handle, syringe needle, needle stand constitutes, needle handle and needle stand are connected to one, the tube chamber of needle handle and the intracavity inter-connection of needle stand, it is characterized in that needle stand is the short tube shape, intracavity at needle stand is stuck on the needle stand inner bottom part inwall by the internal orifice of elastic ring with thin film cartridge type check valve, the collar extension of thin film cartridge type check valve is in the collar extension of needle stand along the inboard, when this thin film cartridge type check valve flows out at no gas, its collar extension is by the gravity of self and the air pressure and the Electrostatic Absorption power in the outside, collar extension can be sealed, when air-breathing, gas can not enter in the thoracic cavity, when the thoracic cavity internal gas pressure is high, as long as gas pressure is greater than ambient pressure in the thoracic cavity, intrathoracic gas can flow out, therefore, can not increase intrathoracic bearing capacity, on needle handle, overlap gum sleeve, gum sleeve is that medical grade rubber is made, the seat end of gum sleeve is fixed on the rubber disc, establish fixedly swivel nut at the upper side of rubber disc, on the outer wall of needle stand, establish external screw thread, fixedly swivel nut on the rubber disc upper side is rotated on the outer wall of needle stand by female thread, by rotating needle stand, the scalable syringe needle stretches out in the length or retraction gum sleeve of gum sleeve port, on the downside of rubber disc, establish the analgesic plaster layer, on the downside of analgesic plaster layer, be provided with plastics envelope film, be bonded in by the analgesic plaster layer on the surrounding skin of puncture orifice, both play fixedly needle handle and the fixedly effect of gum sleeve, played the effect of analgesic antiphlogistic again.This utility model is also implemented by following measure: described needle handle is the Taper Pipe shape, the overall diameter of its needle handle front end is than the little 0.5-1.5mm of overall diameter of needle handle rear end, adapt with it, its front end of the interior diameter of described gum sleeve is also than the little 0.5-1.5mm in rear end, make needle handle in gum sleeve outwards during the withdraw of the needle, syringe needle is relatively easy to be retracted in the gum sleeve, in being punctured to pneumothorax during the appropriate location, by rotating needle stand, syringe needle is retracted in the gum sleeve, make the end of gum sleeve stay position in the pneumothorax, like this, touch in the pneumothorax by the end of gum sleeve, after gas in pneumothorax reduces, internal organs can be touched in the gum sleeve end, but because gum sleeve is softer, so can not stab internal organs; The length of described needle stand is 2-4cm; The balm that described analgesic plaster layer can adopt the pharmacy to sell gets final product.

The beneficial effects of the utility model are: owing to established thin film cartridge type check valve in needle stand, can not bear pressure load so make in the thoracic cavity; Because the gum sleeve that is in the pneumothorax is a flexible pipe, so can or not breathe to shrink to cause and stab internal organs because of the minimizing of gas in the pneumothorax; Owing to increased the analgesic plaster disk, so fixedly gum sleeve prevents from, and can also analgesic antiphlogistic, alleviate the pain that causes because of puncture, so, use safelyr, can be widely used in the first aid of tension pneumothorax.
