Description

A kind of closed drainage catheter component
Technical field
The utility model relates to medical instruments fields, more particularly to a kind of closed drainage catheter component.
Background technique
Country's drainage tube has thick intrathoracic drain, using relatively broad with pigtail drainage tube and central vein at present Connecting tube is the thin drainage tube of representative, ductus thoracicus with needle.
1. thick intrathoracic drain: advantage is that caliber is thick, and drainage effect is good.The disadvantage is that operation need to cut skin 1-2cm, separate Wall of the chest muscle layer and intercostal muscle difficulty be larger, it is often necessary to which thoracic surgery specialist completes, and extra heavy pipe easily oppresses intercostal nerve, makes At patient pain's discomfort, patient respiratory is influenced, coughing up of sputum increases patient suffering and extended treatment time.
2. the thin drainage tube that pigtail drainage tube, central venous catheter are representative: advantage is to operate relatively easy, wound Small, patient suffering is light, restores fast etc., is clinically more and more promoted.But its disadvantage is also obvious: (1) two Kind of tubule is all based on Seldinger tube indwelling technology, needs to puncture, is placed in seal wire, expands skin, set pipe, pull out seal wire etc. and is relatively numerous Trivial process.(2) model of piercing needle limits the diameter of seal wire, and thin seal wire can not support the pigtail hand shaft of thicker internal diameter During the expansion skin device and pigtail hand shaft for causing a degree of merging difficult and thicker in drain pleural effusion art are placed in and The larger easy gas leakage in gap between thin seal wire forms the complication such as iatrogenic pneumothorax.
3. ductus thoracicus with needle: being aluminium alloy or stainless steel-like solid metal puncture guiding needle, thin chest in thick ductus thoracicus with needle There are two kinds of puncture guiding needle of solid metal puncture guiding needle or solid puncture guiding needle inner core+inner sleeve combination in pipe.These Puncture guiding needle cannot remind operator to arrived site of puncture in time when reaching the hydrops or pneumatosis of lesion, need to pull out Needle core sees liquid or connection syringe examination pumping sees gas just and can determine that arrival is intralesional.If having not seen liquid or gas, also It needs to be placed in guiding puncture needle core again, readjusts position, increase operating procedure, difficulty and risk.
Comprehensive present Research both domestic and external, shape can be completely closed in drainage tube placement process by pleural effusion not yet occur It is operated under state, precisely prompt paracentesis depth and the drainage catheter component that iatrogenic pneumothorax occurs and reduces operational risk can be reduced.

Referring to Fig. 6, Fig. 6 is the structural schematic diagram for being passivated tip and sharpening edge.Further preferentially, the puncturing head 22 have passivation tip 221;The two sides at the passivation tip 221 are extended respectively sharpens edge 222, the sharpening edge 222 out It is connect with the puncture guiding needle main body 21.The sharpening edge 222 facilitates the relatively-stationary wall of the chest of penetration site, works as entrance Behind thoracic cavity, the passivation tip 221 can reduce the damage to the lungs for having certain mobility and elasticity, increase the safety of operation Property.
Depth reference is provided in order to guide the drainage tube 1 to enter pleural cavity lesions position the puncture guiding needle 2, Avoid the puncture guiding needle 2 be placed in it is too deep stab internal organ or merging too shallowly abjection skin outside, further decrease operational risk.This Embodiment is preferably provided with multistage graduation mark 212 in the puncture guiding needle main body 21.The difference of graduation mark 212 described in multistage Along the circumferential direction setting of the puncture guiding needle main body 21, and graduation mark 212 described in multistage is parallel to each other.The present embodiment is provided with five Graduation mark 212 described in multistage preferably can be respectively separated 2cm by Duan Suoshu graduation mark 212.
The puncture tail portion 23 is cup dolly.The puncture tail portion 23 increases holding to the puncture guiding needle 2 Holding property makes to operate more stable and be convenient for firmly.
Referring to Fig. 7, Fig. 7 is the preferred structure schematic diagram of connecting tube.The connecting tube 3 includes connecting tube main body 31, pressure Power surge bunker 32, attachment cap 33 and calparine cap 34.
The connecting tube main body 31 has connecting pin and free end, the connecting pin of the connecting tube main body 31 and the manifold 14 connections, the pressure surge bunker 32 be set in the connecting tube main body 31 and be located at the connecting pin and the free end it Between.
The pressure surge bunker 32 is made of the medical silica-gel of elasticity.
The attachment cap 33 is set to the connecting pin of the connecting tube main body 31, and the attachment cap 33 connects with the manifold 14 It connects.Preferably, the attachment cap 33 is provided with internal screw thread, and the attachment cap 33 is connected through a screw thread with the manifold 14.
The free end of the connecting tube main body 31 is provided with external screw thread, can by the free end of the connecting tube main body 31 with Syringe, drainage bottle or calparine cap 34 connect.
It is sealed using the calparine cap 34 when needing, the calparine cap 34 is threadingly attached to the connecting tube master The free end of body 31.It is threadedly coupled convenient for the calparine cap 34 is fixed and is removed when operation.
In order to adjust hydrops drainage at any time, the closed drainage catheter component of the embodiment of the present invention is also provided with clip 4. The clip 4 is located in the connecting tube main body 31, and the clip 4 is located at the connecting pin and the pressure surge bunker 32 Between.It can use the clip 4 to clamp the connecting tube main body 31, and then press from both sides and close the connecting tube 3, and by the clip 4 unclamp, then can be with open drainage.
Before puncture and intubation, the free end of the connecting tube 3 is closed using the calparine cap 34, squeezes the pressure surge bunker 32, and the drainage tube 1 is closed with the clip 4 folder, form negative pressure state.The side opening 122 unclamps after puncturing into skin completely The clip 4, when the puncturing head 22 of the puncture guiding needle 2 is punctured to lesion, negative pressure make the drainage tube 1 be drawn onto hydrops or Gas, liquid or gas can flow out into the connecting tube 3 along the drainage channel 10, precisely prompt the guiding puncture The puncturing head 22 of needle 2 reaches lesion, can reach suitable position by slow release drainage tube 1 under the guidance of puncture guiding needle 2, gram Taken current puncture guide pin need to extract out repeatedly reality inner core seen whether gas or liquid outflow can just determine whether to reach The shortcomings that lesions position, simplified operating process.When drainage, the pressure surge bunker 32 can also be squeezed by interruption to prevent Plugging overcomes by squeezing tube body itself come the deficiency of the effect difference of pre- pipe-blocking-proof.
The drainage tube 1, the puncture guiding needle 2 and the connection of the closed drainage catheter component of the utility model Pipe 3 can be set to the external member of multiple specifications and model.
Referring to Fig. 8, Fig. 8 is the drainage effect schematic diagram of the closed drainage catheter component of the utility model.This is practical The application method of novel closed drainage catheter component:
