Description
Technical field
The present invention relates to technical field of medical instruments, particularly relate to a kind of anti-needle body and to dissociate drainage device for thoracocentesis.
Background technology
Hydrothorax is a kind of common frdquently encountered disease clinically, is the pleural effusion caused by Different types of etiopathogenises.At present, often adopt the mode of puncture drainage to treat clinically, patient's pressure symptom can be alleviated by thoracic puncture drainage, alleviate dyspnea, assay is carried out, for clinical diagnosis and treatment provide valuable information to the hydrops extracted out.
Prior art needs first to strain patient chest skin by medical personnel by two finger expanded supports for the process of patients with pleural, by skin tensioning so that puncture inserting needle, then puncture needle is vertically thrust intrathoracic wall, intrathoracic hydrops is extracted out by puncture needle with syringe, carry out biopsy of pleura with autocratic Pleura biopsy needle after drawing liquid completes, biopsy send pathologic finding.
Existing thoracentesis drainage device comprises puncture needle and syringe mostly, the hydrops in chest is extracted with syringe, after puncture needle thrusts chest, its needle body generally can dissociate, also there is no special needle body fixture at present, needle body is easy to extract in puncture procedure process, cause cross infection, add work difficulty to medical worker.
Summary of the invention
The present invention, for solving the deficiencies in the prior art, provides a kind of anti-needle body simultaneously with good stability easy and simple to handle to dissociate drainage device for thoracocentesis.
The scheme solving the technology of the present invention problem is:
Anti-needle body dissociates drainage device for thoracocentesis, is made up of syringe, syringe cover, operation tube, pressure handle cylinder, upper pressing handle, lower pressure handle, slipmat, locating ring and expanded support locating rack.
Syringe cover is placed on syringe, and operation tube is enclosed within syringe and puts, and pressure handle jacket casing is in operation tube, and described syringe cover all becomes clearance fit relationship with syringe cover, pressure handle cylinder with operation tube with syringe, operation tube.Be that overlap with syringe be the locating ring of holistic annular in the bottom of syringe cover, there is the rubber ring be bonded as one with locating ring the bottom surface of locating ring.
Each described expanded support locating rack is formed by expanded support handle and expanded support bar.Expanded support bar is the bonding jumper of circular arc, and the upper and lower surface of expanded support bar is all bonded with rubber, and the upper surface at the two ends of expanded support bar is hinged with one end of an expanded support handle respectively, and the end of the other end of each expanded support handle and the lateral wall of operation tube is along hinged.Three expanded support locating racks are uniformly distributed in around operation tube, the axial line of the inner of each expanded support handle all point operation cylinder.Upper pressing handle hinged each other and lower pressure handle is had between two expanded support handles of each expanded support locating rack, lower pressure handle is positioned at the below of upper pressing handle, along hinged, the edge of the lower end of lower pressure handle and the upper surface of described locating ring is hinged at the end of the upper end of upper pressing handle and the outer wall of pressure handle cylinder.The bottom surface of lower pressure handle has a groove, and the slipmat of quality of rubber materials is inlayed and is adhered in described groove and the bottom surface of the lower pressure handle of protrusion.The axial line of every upper pressing handle of being hinged for a pair and the equal point operation cylinder of lower pressure handle.
During operation, first syringe is upwards carried, make the needle point of syringe be in the inside of syringe cover, then pressure handle cylinder is upwards carried, make every upper pressing handle of being hinged for a pair and lower pressure handle be straight line at vertical direction.Then by operation tube slide downward, the bottom of bottom lower than locating ring of expanded support bar is made.Then the bottom of the expanded support bar of three expanded support locating racks is affixed on the skin around inserting needle position and also firmly moves down operation tube, three expanded support bars under the promotion of expanded support handle by the skin around inserting needle position to extrapolation, make skin tensioning, then syringe is overlapped slide downward, the bottom surface of locating ring is made to be pressed on skin, and then by pressure handle cylinder slide downward, make the end outwards motion that is hinged of upper pressing handle and lower pressure handle, the slipmat of final lower pressure handle bottom surface is pressed on the upper surface of expanded support bar, article three, upper pressing handle and the folded formation of lower pressure handle become the Cortex Cinnamomi Tamalae being connected expanded support bar and locating ring along locating ring radial direction, make cannot send relative motion between expanded support bar and locating ring, then syringe is moved downward, the needle point of syringe lower end vertically thrusts intrathoracic wall.
Adopt such scheme, compared with prior art, the present invention has following marked improvement:
1. because the present invention is by evenly stretching out the skin around entry point towards three directions being mutually 120 ° around the equally distributed positioning supporting frame of operation tube, compared with the mode that this and use in prior art point tensioning the skin, make the level of stretch of skin more all thoroughly even, be more conducive to inserting needle.
2. because upper pressing handle of the present invention, lower pressure handle and expanded support handle, stay bolt bar and syringe cover together constitute the framework of a three-legged support shape, this just makes the skin around the bottom surface of the axial line of syringe and described three-legged support i.e. entry point keep vertical, therefore this invention ensures that puncture needle can vertically thrust intrathoracic wall, avoid syringe needle situation free after thrusting chest and occur.
3., because the present invention also has the radial direction of upper pressing handle, lower pressure handle to reinforce between locating ring and stay bolt bar, make described three-legged support more firm.
