Abstract

The utility model relates to a covered-edge type puncture drainage needle, which is composed of a puncture needle tube (10) and a drainage needle (20) sheathed inside the puncture needle tube (10). The outer surface of the needle tube (10) is provided with a needling dividing ruler, and the front part of the drainage tube (20) is provided with two symmetrical drainage holes. A C-shaped internal slot (11) is arranged on a handle of the needle tube (10), and a quadrate lug (21) is arranged on a handle of the drainage tube (20). When the needle tube (10) is sheathed on the drainage tube (20), the lug (21) can be fixed inside the C-shaped internal slot (11), and a front window and a rear window conduct running fix. The drainage tube (20) is telescopic inside the needle tube (10). The rear part of the handle of the drainage tube (20) is connected with a trickling guide tube (22) provided with a flow-speed regulator (23), and the rear part of the guide tube (22) can be connected with a negative pressure drainage device.

Description

Puncture drainage needle

This utility model relates to a kind of diagnosis, treatment medical apparatus and instruments, particularly relates to a kind of human body puncture of being used for, and carries out extraction gas, liquid and can keep somewhere front-hidden type puncture, the drain two purpose meedle of constant drainage in the body (comprise vomica washes repeatedly, administration).

In clinical, there be many inside and outside sections disease to discharge gas-liquid and obtain medical treatment or gather assay specimen and clarified a diagnosis by puncture (or surgical incision).Especially in pneumothorax treatment, a kind of emergency measures of necessity especially.It is big, dangerous that present domestic puncture, the applied method in drain aspect and apparatus still exist wound, painful more, sometimes even the problem of severe complications or sequela can take place.Never see the relevant operation of need not operating on from up-to-date medical information with report, can make puncture, the drain overall process is disposable finishes, and is applicable to the advanced apparatus generation of multiple medical diagnosis on disease and treatment.With clinical common thoracentesis diagnosis and treatment pneumothorax, liquid breast is example, domestic following method commonly used and apparatus:

［ 1 ］ thoracentesis needle (Fig. 1): its structure adds a short sebific duct (or connecing threeway) by No. 16 syringe needles and forms, by back syringe inserting needle puncture suction.Can be applicable to extraction hydrothorax or pneumatosis, remove the compressing of gas-liquid, or intrapleural injection is got the chest fluid specimen and done laboratory examination etc. the lung heart.Its shortcoming is that (1) doctor reaches the sensation inserting needle by rule of thumb, and the depth is inaccurate, and along with the discharge of gas-liquid, the multiple lobe of the lung of opening may be stabbed by intravital pin cutting edge of a knife or a sword, causes pneumothorax again; (2) once bleed hypervolia or too urgently can open serious consequences such as producing reactive shock or acute lung edema because of pleural pressure rapid drawdown and lungs are multiple suddenly, and the pin cutting edge of a knife or a sword may be stabbed important organ in vivo, can not keep somewhere relatively for a long time again and do the average rate drain in vivo; (3) open, tension pneumothorax and a large amount of hydrothorax, an extraction gas-liquid often can not solve alleviates the problem that compressing is opened the lobe of the lung again, and the repeated multiple times puncture easily causes subcutaneous emphysema, in the chance of stabbing increase.

［ 2 ］ trocar drain: adopt by before the sleeve pipe puncture of being made up of the sleeve pipe and the supporting with it solid nook closing member of inclined-plane pin cutting edge of a knife or a sword, it is long to need to cut skin 4～5mm with scalpel, then can inserting needle.Transfer to nook closing member behind the inserting needle, reuse catheter or silicon are moulded conduit and are inserted in the thoracic cavity in sleeve pipe, and then transfer to sleeve pipe, the conduit other end are connect negative pressure device such as water-sealed drainage bottle and carry out drain.This kind method has avoided stabbing the possibility of internal organs, also realized persistence drain purpose in the indwelling body, but except will being equipped with the scalpel operation, its wound is bigger, and when transfering to nook closing member, outside air directly enters the thoracic cavity, causes the thoracic cavity open artificially, thereby increased the chance of bacterial infection, produced complication such as pleuritis.In addition, soft thin silicon is moulded conduit and is easily blocked, and influences effective drainage.

［ 3 ］ surgical method incision and drainage: for drain aerofluxus liquid fully, extensively take surgery successively to cut thoracic wall and pleura visceralis at present, directly thick sebific duct is inserted the method that constant drainage is carried out in the thoracic cavity.This method is abundant than trocar drain, the aerofluxus liquid measure is big.But (1) surgery operating wound and degree of opening are also bigger.Drain process mesothorax intracavity bacterial infection or sebific duct stimulate the chest pain that is produced, and the case history that fever and thoracic cavity are oozed out is very many, often needs to widely apply antibiotic prophylaxis, control infection.(2) the local pleural adhesion of postoperative, the unbalance stress part involves during lung respiratory movement, can become lung surface pleura and tear, and occurs the open pneumothorax that is difficult to heal even the immediate cause of hemothorax once more.

In a word, ubiquity unsafe or the big complicated operation of wound and developing complications even the sequela problem in puncture, the drain at present.

The purpose of this utility model is to the internist provides a kind of easy and simple to handle safe in utilization, reduces complication and the sequela that occurs in the treatment to greatest extent, and can the disposable puncture drainage needle with sleeving and sealing cap of finishing puncture and drainage.

Puncture drainage needle with sleeving and sealing cap of the present utility model is made up of bevelled puncture needle tubing of front end and the cover blunt drainage tube of nose circle inside.There are two symmetric conduction holes at 2 millimeters places of drainage tube front end.The inserting needle rule is arranged on the needle tubing surface.Have ［ font inside groove on the needle tubing handle.Have the square projection on the drainage tube handle and can be fixed on that ［ front window or the rear window of font inside groove block, projection places rear window to be needled in the body, push projection to front window with hands then, make drainage tube, the pin cutting edge of a knife or a sword is covered in drainage tube carried out drain and the unlikely internal organs of stabbing by leaning out in the puncture needle.

Embodiment:

Puncture drainage needle with sleeving and sealing cap of the present utility model is to be made of puncture needle tubing 10, drainage tube 20.Wherein, ［ projection 21 on font inside groove 11 drainage tubes 20 can ［ sliding before and after the font inside groove and locating in needle tubing 10 handles to have one on needle tubing 10 handles.The conduction hole that drainage tube 20 front portions have two knots to claim.Drainage tube 20 rear portions connect drip conduit 22, and a flow velocity demodulator 23 is installed on conduit 22, and the conduit rear portion can connect depression drainage device.Needle tubing 10 surfaces have the inserting needle scale.

Draw water when using puncture drainage needle with sleeving and sealing cap to diagnose, blood or when carrying out aerofluxus, discharge opeing treatment, need not operate on, according to the syringe needle scale.Directly syringe needle 10 is penetrated in the body, the front window that is fixed on needle tubing 10 with hand push projection 21 blocks then, drainage tube 20 can be released outside the needle tubings, and the needle tubing cutting edge of a knife or a sword is screened.Drainage tube 20 rear portions connect the drip conduit 22 of a band flow regulator 23, and conduit 22 rear portions can connect with depression drainage device, and like this, drainage tube can safety stays the thoracic cavity or other position continues, drain uniformly.
