Description
Technical field
This utility model belongs to the medical puncturing technique with the apparatus field relevant to thoracic cavity, relates to a kind of safety type thoracentesis needle.
Background technology
Pleurocentesis, refers to there being the patient of hydrothorax or pneumatosis, in order to diagnose and to treat the needs of disease and extract a kind of technology of hydrops or pneumatosis by thoracentesis needle.The complication of thoracentesis has that pleura reaction, hemothorax, pneumothorax, puncture orifice are hemorrhage, thoracic wall cellulitis, empyema and air embolism etc.Cause the reason of above-mentioned complication to be described below: hemothorax is many owing to puncturing due to intercostal artery and vein; Pneumothorax can not clamp due to sebific duct, due to leaking-in air, can be punctured due to pin scratches because of the lung tissue surface of acutely coughing of patient in piercing process yet; When thoracic wall cellulitis and empyema are puncture, sterilization does not strictly cause that antibacterial infects; Puncture needle contact pleura can cause pleura reaction, and its clinical manifestation is uncomfortable in chest, chest pain, pale complexion, palpitating speed and the discomfort such as dizzy.Above-mentioned complication have an inevitable factor, but defect in the design of the thoracentesis needle of prior art is also to cause one of factor that complication occurs.
Existing thoracentesis needle is comprised of needle tubing, needle stand, sebific duct, and specifically one end of needle tubing is sharp-pointed syringe needle, and the other end of needle tubing is established needle stand, and needle stand is connected with sebific duct.Its syringe needle is tip inclined-plane, and in piercing process, this puncture needle may cause following damage to patient: (1) its tip is exposed, sharp keen, very easily damages lung tissue, or in piercing process, damages patient's intercostal blood vessel, nerve and lung tissue; (2) syringe nipple be connected with rubber tube closely or the loose pincers of assistant air may occur enters breast chamber too early; (3) extract after 50ml, need clamping rubber tube, drains liquid gas in syringe, more repeatedly extracts, so not only time-consuming at every turn, and single being difficult to carries out; (4) depth of needle is difficult to steady control, and operator's attention is not slightly concentrated, and needle body is moved forward and backward in thoracic cavity, increases the probability of damaged lung tissue.
Utility model content
This utility model is that the technical scheme that its technical problem of solution is taked is, design a kind of safety type thoracentesis needle, comprise needle body, the rear end of needle body is provided with needle stand, at described needle body rear portion, be provided with one section of external screw thread, this section of externally threaded length is 1/2nd of needle body length, on this section of external screw thread, after going to, be threaded successively limited location cover and anti-back circle, and the front end of described needle body is crooked arc; Also comprise a latex tubing, this latex tubing is comprised of front connector pipe, rear junction block, latex balloon, one-way pressure valve, changeover valve, front connector pipe and rear junction block are separately positioned on the rear and front end of latex balloon and are communicated with latex balloon, one-way pressure valve is arranged on the inside in front connector pipe stage casing, changeover valve is arranged on the stage casing of rear junction block, the head of front connector pipe is communicated with needle stand, and the afterbody of rear junction block is connected with adaptor, and adaptor is provided with syringe interface and drainage tube interface.
During use, first position-limiting cover and anti-back circle are placed near needle stand, again by changeover valve in opening, follow hand-held needle stand needle body is aimed to site of puncture puncture, because needle body front end is crooked arc, can avoid directly penetrating patient's intercostal blood vessel or coup injury patient's intercostal nerves and lung tissue, when thrusting after subcutaneous, needle point pinches flat latex balloon with hands, gas in latex balloon is discharged from the changeover valve of opening, gas is closed changeover valve after discharging, now latex balloon cannot suck gas in negative pressure state from needle point and changeover valve side, both kept flat form, continue careful puncture, when needle point punctures parietal pleura moment, latex balloon sucks gas or liquid from needle point, latex balloon restores, by observing latex balloon state, even if abecedarian also can find out needle body, oneself thrusts breast chamber, simple and convenient safety, simultaneously because needle body front end is crooked arc, needle body rests in thoracic cavity can not cause major injury to visceral pleura, at needle body, puncture into after desired depth, position-limiting cover is rotated to contacting skin, again anti-back circle is held out against to position-limiting cover, so just can prevent the unexpected breast chamber of deeply thrusting of needle body, more safe and reliable, prevented the generation of contingency, secondly changeover valve is now in closed condition, add uniaxial pressure valve, guaranteed not have air to enter breast chamber from needle body, stopped the generation of pneumothorax, in the time of need to extracting hydrops or pneumatosis, syringe or drainage system are docked with syringe interface or drainage tube interface on adaptor, then opening changeover valve can operate, one-way pressure valve can also guarantee that pneumatosis or hydrops can not reflux, improved work efficiency, safer practicality, in the time of need to changing syringe, close that changeover valve can guarantee not have gas after syringe pulls out or liquid enters or flows out, easy to operate.In sum, this novel a kind of safety type thoracentesis needle can effectively prevent the appearance of iatrogenic pulmonary complication in thoracentesis process, and simple in structure, easy to operate, practical, is convenient to promote the use of in Respiratory Medicine.
