Detailed description of the invention
Multifunctional nerve blockage puncture pin as shown in Figure 1, comprise needle tubing 1 and be positioned at the syringe needle 2 of needle tubing 1 front end, the tail end of needle tubing 1 is connected to the support 3 of metal, and support 3 is in tubular, its inside has the passage being communicated with needle tubing 1 inner chamber, and this passage and needle tubing 1 inner chamber are on an axis.Flexible pressing body 4 is overlapped in support 3 periphery, is loaded with local anesthetic 5 between elasticity pressing body 4 and support 3 outer wall, and support 3 is provided with the hole 6 of local anesthetic 5 introduction channel.
During puncture, as shown in Figure 3, elasticity pressing body 4 is pressed into support 3 by forefinger and the thumb of holding pin hands, is extruded, after puncture needle thrusts skin by local anaesthetics from hole 6, finger unclamps, move after holding pin position (cause elasticity pressing body after loosing one's grip and between negative pressure), as syringe needle 2 thrusts blood vessel, then due to intravascular pressure and underbalance effect, vessel inner blood can flow in elasticity pressing body 4, judges accordingly to avoid intravascular injection.
As further preferred embodiment, hole 6 is covered with isolating membrane 7, after elasticity pressing body 4 pressurized, isolating membrane 7 is washed open by local anesthetic 5.Isolating membrane 7 original state to be all overlying on hole 6 passage and local anesthetic 5 to be isolated, and is washed open after pressurized by local anesthetic 5, but its edge has at least part to be connected with the wall in hole 6, to prevent isolating membrane 7 blocking channel always.
As further preferred embodiment, as depicted in figs. 1 and 2, elasticity pressing body 4 is transparent rubber sleeve, and first it has elasticity, and material transparent in addition facilitates medical personnel to observe inner situation, to have judged whether that blood pressure flows into.
As further preferred embodiment, syringe needle 2 is coniform, compared to current beveled point, less to nerve injury.
As further preferred embodiment, the perisporium of syringe needle 2 is provided with liquid outlet 21.
As further preferred embodiment, needle tubing 1 is made by development material or needle tubing 1 is coated with development material layers.The development material of the main B ultrasonic of development material, has these a large amount of development materials on the market, such as can adopt the B ultrasonic developer composition of application number involved by 0311318.5 patent, also can adopt other existing development materials.By development material, this puncture needle can be combined B ultrasonic and be used, and complete operation under B ultrasonic display, reduces the generation of nerve block related complication as far as possible.
As further preferred embodiment, needle tubing 1 is provided with scale 11, and these scales 11 can develop equally, and associating B ultrasonic uses.
As further preferred embodiment, also comprise syringe union joint 8, syringe union joint 8 is connected in passage by flexible pipe 81, and medical personnel connect syringe by syringe union joint 8 and inject to puncture needle.
As further preferred embodiment, syringe union joint 8 is circumscribed with pressure display unit 82, as small-sized Pressure gauge, can show the pressure (15psi, 20psi, 25psi) during injection, with objective display injection pressure, avoid neural inner injection as far as possible.
As further preferred embodiment, also comprise nerve stimulation instrument line 9, nerve stimulation instrument line 9 is connected on syringe needle 2 through passage and needle tubing 1, and syringe needle 2 is the metal material of conduction, nerve stimulation instrument is electrically connected, with its conbined usage by nerve stimulation instrument line 9.
With reference to second embodiment of figure 3 and Fig. 4, the Pressure gauge of the no longer outer connection small of syringe union joint 8, but connect pressure alarm 83 capable of automatic alarm, this pressure alarm 83 is provided with electronic display 84, for showing injection pressure.
The concrete structure of this pressure alarm 83 and operation principle can with reference to such as under type:
Syringe union joint 8 is approximately tubulose, has a hole at its outer wall.Described pressure alarm 83 comprises thin film 831, two groups of swept resistance silks 832 and two microprocessors 833 below thin film 831.Wherein, thin film 831 is covered on hole and is sealed in hole, and two swept resistance silks 832 are attached to thin film 831 surface, but the length of thin film 831 is longer than in the end of every bar swept resistance silk 832, and two swept resistance silks 832 are cross-shaped but insulated from each other.Every bar swept resistance silk 832 is connected with a microprocessor 833 in the position of thin film 831 both sides by the metallic object of wire or conduction and is supplied a stable voltage.The metallic object of wire or conduction is not fixedly connected with swept resistance silk 832, but being slidably connected of always keeping in touch.
When injecting, bulging deformation is there is in thin film 831 because being subject to the pressure of syringe union joint 8 internal liquid, swept resistance silk 832 is out of shape with thin film 831 and protruding, because its distortion, swept resistance silk 832 meeting opposing leads or conducting metal body generation slippage, but the absolute position of wire or conducting metal body is constant, namely the relative length of the part of swept resistance silk 832 above thin film 831 becomes large; Meanwhile, again because voltage constant, according to I=U/R, namely create change by the electric current of microprocessor 833, microprocessor 833 by the change of electric current through date processing change into distance that swept resistance silk 832 slides with thus obtain the changing value of pressure and pressure.
When pressure is larger, thin film 831 deformation quantity is larger, and curent change is also larger, and therefore the change of pressure is also larger.
This embodiment is provided with two swept resistance silks 832 and two microprocessors 833, can measure the data obtained correct process.
By above mode, pressure energy during injection is automatically detected, shows, and automatic feedback thus send warning.The puncture needle for nerve block of above-mentioned two embodiments has and is the scope of application widely, at least can be used for:
1. traditional blind spy peripheral blockade;
2.B is super guides lower peripheral blockade;
3. nerve stimulation instrument guides lower peripheral blockade.
The above is the preferred embodiment of the present invention, and it does not form limiting the scope of the invention.
