Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of drainage system based on Wicresoft and blockage resisting hydrothorax.
Background technology
Drain pleural effusion is common operation in clinical position, drainage-fluid can be chemically examined clear and definite hydrops character to assist diagnosis, also can extract hydrops and alleviate lungs pressure symptom, also can carry out chest cavity administration by it by it.Existing hydrothorax puncture drainage apparatus-form is various.The most frequently used traditional thoracic drainage and thoracentesis equipment mainly contains following two kinds: 1. utilize metal thoracentesis needle, with syringe extract hydrothorax after entering thoracic cavity under local anaesthesia.To once extracting, hydrops amount is restricted, therefore a large amount of hydrothorax or malignant pleural effusion need repeated multiple times row thoracic drainage and thoracentesis art; Drain hydrothorax needs again to puncture next time, and patient need bear misery and puncture risks (spike pierces lung causes pneumothorax) again.2. pleural cavity closed drainage device: need incision patient thoracic wall to be about 1cm and go directly in thoracic cavity, place diameter and be about 0.5cm silica gel drainage tube, external drainage bag constant drainage.This device has following shortcoming: comparatively large to patient trauma, is easy to infect; Outside air enters pleural space and causes pneumothorax; Drainage tube slippage.
When doing pleurocentesis, as shown in Figure 1, under local anaesthesia, the metal puncture of the foot section brought rubber tube is needled into thoracic cavity, external syringe, extracts hydrothorax.Puncture needle is extracted and covering of sterilizing after end.If the state of an illness needs drain hydrothorax again, then need repetition all operations.The pleural cavity closed drainage device used as shown in Figure 2, needs to cut skin and is about 1cm, is separated subcutaneous tissue and muscle and goes directly pleural space, implant soft rubber pipe, external drainage bag or drainage bottle.
In view of medically drain pleural effusion has speed and quantitative limitation, the short time, a large amount of drain can cause pulmonary edema.Therefore a lot of repeated multiple times drain of needs of patients.Use the drain of thoracentesis needle repeated localised puncture large to patient trauma; Careless manipulation, draw point punctures lungs and causes pneumothorax.Existing pleural cavity closed drainage device after the implantation can indwelling a couple of days, can regulate drainage flow and speed as required.But separation thoracic wall holostrome need be cut and be about 1cm, comparatively large to patient trauma, be easy to infect; Outside air enters pleural space and causes pneumothorax; Drainage tube slippage may.Patient is handicapped.
Utility model content

Detailed description of the invention
Below in conjunction with detailed description of the invention, this utility model is described in detail.
This utility model provides a kind of drainage system based on Wicresoft and blockage resisting hydrothorax, as shown in Figure 3, the puncture needle 1 comprising hollow (can select syringe, and porose by wearing in the middle part of syringe) and seal wire 2, seal wire 2 passes from the two ends of puncture needle 1, the front end of seal wire 2 is provided with crotch, seal wire 2 is arranged with and expands skin conduit 3, expand on skin conduit 3 and be connected with drainage tube 4, one end that drainage tube 4 inserts thoracic cavity is provided with the self-expanding mechanism 11 of hollow, the other end of drainage tube 4 is provided with interface 10, drainage tube 4 is provided with scale marker 9 and clip 5, interface 10 is connected with calparine cap 6 or drainage bag mechanism.
Drainage bag mechanism comprises drainage bag 7, and the two ends of drainage bag 7 are respectively arranged with feed tube 14 and drain pipe 15, drain pipe 15 are provided with valve mechanism 12.
As shown in Figure 6, valve mechanism 12 comprises spherical drain valve 16 and the knob 8 of interconnective hollow, and drain valve 16 is arranged in drain pipe 15, and knob 8 is arranged at outside drain pipe 15.Knob 8 is provided with fixed axis 13, knob 8 is connected by fixed axis 13 with drain valve 16.
In use, during for patients with pleural puncture drainage, first thrust hydrothorax by puncture needle 1, seal wire 2 enters hydrothorax place along puncture needle afterbody.Fixing seal wire 2 is motionless, extracts puncture needle 1, expansion skin conduit 3 is thrust thoracic cavity along seal wire 2 and carries out expansion skin, enter thoracic cavity to facilitate drainage tube 4.Fixing seal wire is motionless, extracts and expands skin conduit 3, drainage tube 4 is sent into thoracic cavity, and exit seal wire 2 and fixing drainage tube 4, wherein, seal wire 2 plays the role of positioning, and the organization grows act as around by seal wire expanding skin conduit 3 facilitates drainage tube 4 to enter.Because the self-expanding mechanism 11 of drainage tube 4 front end hollow expands, expand draining hole area to a great extent, greatly reduce the probability that blocking occurs, meanwhile, self-expanding mechanism 11 also serves and this device is fixed to intrathoracic effect.If tangible material is too much in hydrothorax, cause tube chamber to block, after reaching target drainage flow, remove drainage bag 7, calparine cap 6 is connected with interface 10, prevents external source from polluting, safe and reliable.Patient's portability drainage tube institution freedom is movable, compared with the past equipment, practical and convenient, significantly improves patient comfort degree.
Rinsed by interface 10 by syringe.Also carry out chest cavity administration by this device simultaneously and (as tuberculous pleural effusion patient, inject adhesion agent; Bacterial infection patients, injection of antibiotics).As for qualification drainage-fluid character (whether have cancerous cell as searched, repeated multiple times sampling may be needed to determine), hydrothorax chemical examination can be extracted, for clinical treatment provides objective evidence by this equipment at any time.
When needing drain to discharge, rotary knob 8, makes drain valve 16 opening state, as shown in Figure 7, now the drainage-fluid in drainage bag 7 can be discharged from drain pipe 15, when not needing to discharge drain, rotary knob 8, makes drain valve 16 be in closure state, as shown in Figure 6, now, be in closed state between drain pipe 15 and drainage bag 7, drainage bag mechanism can be made like this to reuse, saved resource, and can effectively avoid medical personnel to contact drain, save manpower and materials.
This device is sent into thoracic cavity by deep venouspuncture puncture technique by this device, can repeat the drain of breast hydrops, little to patient trauma.The self-expanding mechanism of drainage tube leading portion is made up of Elastic memory material, without sharp tips, automatically swelling in thoracic cavity.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but this utility model is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, many variations can also be made to it.
