Abstract
The utility model relates to an automatically-controlled injection boosting device which is a medical remote-control injection boosting device during injecting and is especially suitable for the vivo graphy under the irradiation of the X-ray. As the vivo graphy of liver and gallbladder surgery, urinary surgery, gynecology, orthopaedics, etc., applied under the irradiation of the X-ray is increased, the doctor suffers from the severe radioactive damage. The utility model replaces the operation of the doctor and avoids the damage of the doctor. The utility model is composed of an electric motor, a gear wheel, a propeller and a remote-control device. The propelling plate of the propeller is in rail connection with a positioning plate, and the baffle plate of the propeller is in embedding connection with a pressure control device. When in use, the pressure control device effectively and automatically decelerates or stops injecting according to the injected resistance force.
Description
This utility model is a kind of injection assist device of the medical automatic control of the time using about injection.
In the clinical medicine as Genneral Surgery, Urology Surgery, gynecological, orthopaedics always need the doctor directly under radiation exposure in the patient body injectable drug, especially in operation process, the doctor is subjected to inevitable radiation injury, and it is more and more that this generic operation is carried out, and the radiation injury that causes is more serious naturally.For avoiding this type of damage, by Chinese patent CN8621043 μ a kind of electric pushing-aid device of being made up of micromachine, gear, worm screw, screw mandrel, propeller, potentiometer etc. has been proposed, can realize its automatic boosting injection effect.But it does not inject pressure control device, is no more than motor power as long as inject resistance, and it is all done and continues to inject motion.Like this, when injected organ in the body has when blocking, will cause the organ damage of breaking; When pressure surpasses the holding capacity of syringe, will cause the damage of syringe.Therefore, it is used to have the organ that blocks that certain danger is arranged.
The purpose of this utility model provides a kind of injection assist device of automatic control, it can be effectively, control injection process automatically according to injecting pressure safely, thereby reach the purpose of avoiding operator to suffer radiation injury and avoiding injected visceral organ injury; It can also be used for general clinically intravenous injection, reaches the labour-saving purpose.
Technology of the present utility model is achieved in that it is made of motor (9), gear (7,8), propeller (3) and beepbox (2 ', 23).Feature of the present utility model is: propeller (3) is made up of pushing plate (11) and baffle plate (1), and pushing plate (11) matches with the guide-track groove (12) of location-plate (13) below, and both are guide rail and connect; There is the tooth that matches with gear (7) pushing plate (11) below, and is with the latter and is connected with a joggle; Baffle plate (1,15) is gone up the setting pressure control device, and the latter be pressure controller or be made up of pressure experience device (2 ') and beepbox (23) that pressure control device is connected with syringe (16), injects resistance with direct impression.
According to pushing plate (11) forward travel distance, several distance display switches (5) have been installed on location-plate (13), and have been connected, to show the injection process with corresponding display lamp (4).
Motor (9) starts, transmitting gear (8,7), the latter drives pushing plate (11), and pushing plate (11) is by the preceding syringe bolt (18) that pushes away of baffle plate (1), when propelling resistance reaches the intensity that pressure control device limits, pressure control device just stops or the reducing motor running automatically, thereby the power of injecting is controlled within certain scope, realizes that it is effective, safe boost function.Simultaneously, pushing plate is constantly opened different distance display switches (5) in the process of advancing, make operator can grasp nimblely medicine injection volume and take the photograph sheet opportunity.
This utility model is because there is pressure control device, so can control injecting of syringe automatically according to the big or small effective and safe ground of injecting pressure; Pressure control device is connected with syringe, and therefore, piezometry is accurate; Pushing plate is guide rail with location-plate and is connected, and it is steady especially to make syringe inject motion; According to position display switch and the corresponding display lamp that the propulsive distance of syringe bolt is established, make that to take the photograph sheet operation very convenient.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1: the assist device sketch map is injected in control automatically.
Fig. 2: beepbox sketch map.
This utility model is made up of motor (9), plurality of gears (7,8), location-plate (13), pushing plate (11), baffle plate (1,15), pressure controller (2) or pressure experience device (2 ') and beepbox (23), except that beepbox (23), wrap up by shell (6).There are swallow-tail form or T shape or triangular guide groove (12) in location-plate (13) below, and there is the semi-circular groove (17) that matches with syringe (16) profile location-plate (13) top, with fixing syringe (16).The tooth that matches with gear (7) is arranged below the pushing plate (11), and be meshing with the latter and be connected, baffle plate (1,15) is connected with pushing plate (11) with location-plate (13) respectively, and connect with the two ends of syringe (16), before plaing a part, baffle plate (1) pushes away syringe bolt (18).Pressure controller (2) or pressure experience device (2 ') can be contained on baffle plate (1) or the baffle plate (15), and the former directly contacts with syringe (16), injects the size of resistance with induction.
Pressure control device is pressure controller (2) or is made up of pressure experience device (2 ') and beepbox (23).Remote control unit (23) is connected with motor (9) with pressure experience device (2 ') respectively by lead, it comprises computer (single piece plate) (19), on and off switch (20), display lamp (21), screen (22), has to analyze pressure experience device (2 ') information that transmits and the function of controlling this utility model running.
Location-plate (13) is gone up the difference of the distance that is pushed into according to syringe bolt (18), different distance display switches (5) and corresponding display lamp (4) are installed, it touches different distance display switches (5) when moving forward by baffle plate (1), to realize the different display lamp of its switch color (4), with the medicine surplus in the prompting syringe (16).
Operation process of the present utility model: turn on the power switch (20), motor (9) starts and driven gear (8,7), drives pushing plate (11) by gear (7) after the speed change, baffle plate (1) with pushing plate (11) along guide-track groove (12) to front slide, thereby advance syringe bolt (18).When baffle plate (1) touched range switch (5), corresponding red led (4) was opened, and prompting syringe (16) inner liquid medicine surplus this moment is 2m1, and operator can select to take the photograph sheet opportunity according to it.Meanwhile, in the process of baffle plate (1) reach, pressure control device (2 ') is constantly experienced propelling resistance, when resistance surpasses tolerance band, the pressure experience device (2 ', 23) can send instruction, deceleration or out of service automatically automatically.
