Description
TECHNICAL FIELD
[0001] The present application relates to the field of syringes, in particular to an oral anesthesia booster and a control method. BACKGROUND
[0002] An oral anesthesia syringe generally needs to be operated with one hand, and the needle is first held to puncture, then advanced to the appropriate position, and then needs to be withdrawn, and after confirming that the needle tip is not in the blood vessel position, slow injection is performed. Generally, medical personnel need to hold other instruments with one hand and hold the oral anesthesia syringe with the other hand, so it is not convenient to control the oral anesthesia syringe with both hands. The existing oral anesthesia syringe mainly has a manual syringe and an oral anesthesia booster that uses a small motor to achieve automatic pushing and suction. The manual syringe needs to control the injection speed and injection volume according to experience, and needs to accumulate certain experience, so the operation is difficult. The automatic oral anesthesia booster also has some problems. The oral anesthesia booster is small in size, and multiple keys need to be arranged in a straight line. If the keys are arranged side by side, the spacing is small, and it is difficult to accurately control. When the spacing is large, it is difficult to control with one hand, and the operation amplitude is large when controlling, which may affect the position of the needle. Therefore, although the existing oral anesthesia booster is labor-saving, it is not very convenient to operate and control.
[0003] A patent application with the name "Oral anesthesia injection device" and the patent announcement number "CN113425949B" discloses an oral anesthesia injection device, which comprises a shell, a push barrel, a motor and a main control chip. The process of the main control chip controlling the working state of the motor is as follows: receiving the trigger signal collected by the trigger signal collection assembly; when the trigger signal is received, a forward rotation control signal is sent, which is used to drive the motor to rotate forward; when the received trigger signal is interrupted, a reverse rotation control signal is sent, which is used to drive the motor to rotate in reverse. The trigger signal collection assembly is arranged on the shell, and the trigger signal input by the user is collected through the trigger signal collection assembly. When the trigger signal is received, the main control chip sends a forward rotation control signal to drive the motor to rotate forward. When the received trigger signal is interrupted, the main control chip sends a reverse rotation control signal to drive the motor to rotate in reverse. The doctor only needs to lift his finger to control the whole injection process, which minimizes unnecessary movement of the needle during injection and facilitates verification of the needle position. However, this design still has some defects. During oral anesthesia, gloves are generally worn. Ordinary gloves will affect touch control. In addition, it only controls one key, and it is difficult to perform operations for adjusting multiple aspects such as injection dose, injection speed, advance and retreat control. It mainly executes certain steps according to a certain procedure, and cannot be freely adjusted. The control flexibility is poor. SUMMARY
[0004] The present application provides an oral anesthesia booster and a control method to at least solve the single-hand control technical problem existing in the prior art.
[0005] According to a first aspect of the present application, an oral anesthesia booster device is provided, comprising an injection body, a control module and a control circuit board, the control module and the control circuit board are installed on the injection body, the control circuit board is provided with at least a first control switch and a second control switch, the control module is provided with at least a first control member, the first control member is directly or indirectly installed on the injection body in a rotatable manner, the first control member triggers the first control switch when rotated in a first direction, and the first control member triggers the second control switch when rotated in a second direction.
[0006] Compared with the prior art, the oral anesthesia booster device and the control method have the following beneficial effects: Thus, different rotations at the same position can trigger two different control switches to achieve different control functions, facilitating dose adjustment and injection control when holding the oral anesthesia injection device with one hand. The triggering control of the control switches can be single click, double click, constant pressing, etc. Different functions can be achieved by combining the first control switch and the second control switch, for example, single click of the first control switch by rotating the first control member in the first direction once for regular bolus injection, double click of the first control switch by rotating the first control member in the first direction twice for slow bolus injection, and long press of the first control switch by maintaining the rotation angle of the first control member in the first direction for fast bolus injection. Single click of the second control switch by rotating the first control member in the second direction once for regular back extraction, double click of the second control switch by rotating the first control member in the second direction twice for slow back extraction, and long press of the second control switch by maintaining the rotation angle of the first control member in the second direction for fast back extraction. Single click, double click and long press can also be defined as the difference in back extraction amount, i.e. single click is the first back extraction amount, double click is the second back extraction amount, and long press is continuous back extraction. These functions can be realized by modifying the program. The present application provides a hardware basis by setting the first control switch and the second control switch, and the first control switch and the second control switch are controlled by rotating the first control member, i.e. different rotation methods at the same position can achieve different function control. In addition, for the booster device with sound reminder function, the second control switch can be set as volume adjustment function or volume off function, i.e. the function can be customized according to user demand, and the program can be modified.
[0007] In an implementation manner, the control circuit board is provided with a third control switch, and the first control member triggers the third control switch when moved in the first axis direction. Setting different direction control switches can reduce misoperation, i.e. the control switch can be controlled by the sense of touch of the finger to increase the convenience of operation.
[0008] In an embodiment, the control circuit board is further provided with a fourth control switch and a fifth control switch, the fourth control switch and the fifth control switch are arranged on both sides of the third control switch, the first control switch and the second control switch are arranged on both sides of the third control switch, the first control switch and the second control switch are arranged along the second axis direction, and the fourth control switch and the fifth control switch are arranged along the third axis direction. In this way, the five control switches can be controlled by the first control member, and complex control operations or parameter adjustments can be realized by program definition setting, and thus the control is more convenient than the prior art.
[0009] In an embodiment, the control module is further provided with a second control member, the second control member is rotatably mounted on the injection body, and the first control member is rotatably mounted on the second control member; or the first control member is mounted on the injection body by a ball hinge, so that the first control member can rotate relative to the injection body in four rotation directions around at least two rotation axes, thereby controlling the four control switches.
[0010] In an embodiment, the first control member is provided with a finger ring, the first control member is located in the first axis direction of the finger ring, and the finger ring is provided with a finger hole in the second axis direction, so that the thumb can be inserted into the finger hole in the second axis direction. The thumb is more flexible and has more power than other fingers, which facilitates the rotation of the first control member in different directions to trigger different control switches and complete complex control.
[0011] In an embodiment, the finger ring includes a positioning half-ring seat and an elastic buckling belt, the positioning half-ring seat is fixedly formed in one body with the first control member, and the two ends of the positioning half-ring seat extend upward and are buckled with the two ends of the elastic buckling belt by a buckle structure. In this way, the thumb is inserted into the fixed range of the positioning half-ring seat, and the elastic buckling belt can fix the finger ring on the thumb, and the movement of the thumb can realize the control of the control switch, and the elastic buckling belt has a certain elasticity and is not easy to fall off.
[0012] In an embodiment, the ring includes a positioning seat and a ring-shaped finger band, the ring-shaped finger band is capable of being wrapped around the thumb, the ring-shaped finger band is provided with an elastic clamping hole, the positioning seat is fixed to the first control member, and the positioning seat is provided with a clamping portion which is clamped with the elastic clamping hole. The ring-shaped finger band is made of soft material, which is more comfortable to use and can be more firmly fixed to the thumb, facilitating the control of the thumb. The ring-shaped finger band is provided with the elastic clamping hole and the clamping portion to achieve elastic clamping. Under the action of external force, the clamping portion can be removed from the elastic clamping hole, that is, after the anesthetic injection is completed, the injection body can be removed first, or the injection body can be temporarily removed during use. In addition, the ring-shaped finger band is separated from the injection body, which is easier to wear, and the ring-shaped finger band can be worn with the assistance of others. When anesthetic injection is needed, the clamping portion is clamped into the elastic clamping hole. The ring-shaped finger band can also be made into an integrated structure with a glove. Only the elastic clamping hole needs to be provided at the corresponding position of the glove. The elastic clamping hole can be a blind hole, which does not affect the use of the glove. In addition, the glove can be customized as a special glove for oral surgery.
[0013] In an embodiment, the ring-shaped finger band includes a first ring-shaped segment and a second ring-shaped segment. When worn, the first ring-shaped segment is located at the proximal phalanx, and the second ring-shaped segment is located at the distal phalanx. The first ring-shaped segment and the second ring-shaped segment are at least partially connected. The second ring-shaped segment is tapered, such that the circumference of the second ring-shaped segment at a position close to the first ring-shaped segment is greater than the circumference of the second ring-shaped segment at a position away from the first ring-shaped segment. The elastic clamping hole is provided on the second ring-shaped segment. The front end of the finger is relatively thin in thickness compared to the rear end, so the circumference of the front end is smaller than that of the rear end. The circumference of the joint position is also slightly larger than the circumference of the phalanges at both ends of the joint. The first ring-shaped segment is fixed to the proximal phalanx and is not easily removed from the finger under the action of the joint. However, the thumb is more flexible at the distal phalanx. Therefore, the elastic clamping hole is provided on the second ring-shaped segment. The pulling force of the first ring-shaped segment on the second ring-shaped segment is used to assist in limiting the position of the second ring-shaped segment. The tapered structure of the second ring-shaped segment can also avoid large-scale movement of the second ring-shaped segment towards the first ring-shaped segment. In this way, the first control member can be well controlled by the thumb.
[0014] According to a second aspect of the present application, a control method of an oral anesthetic booster instrument is provided. In a first interface, a first control switch outputs an injection instruction after being triggered, and a second control switch outputs a back-pulling instruction after being triggered. In an injection or back-pulling interface, a fourth control switch outputs an acceleration instruction after being triggered, a fifth control switch outputs a deceleration instruction after being triggered, and a third control switch outputs an emergency stop instruction after being triggered. The first interface can be a main interface, and the operation is very convenient after the instrument is directly controlled after being turned on. The third control switch can be set as a start button, that is, the instrument can be started by pressing the button. In this way, there is no need to set parameters after starting the instrument before operation, and the instrument can be operated with one hand.
[0015] In an implementation, under the first interface, the first control switch triggers once to output a slow bolus injection instruction, the first control switch triggers twice in succession within one second to output a fast bolus injection instruction, and the first control switch triggers once within one second to trigger the second control switch to output a periodontal membrane bolus injection instruction. In this way, the mode switching is more convenient and no pre-setting is required.

An elastic buckle hole 184 is arranged on the second ring-shaped section 189. The positioning seat 182 is arranged to be buckled with the elastic buckle hole 184. The positioning seat 182 can be arranged to be buckled with the elastic buckle hole 184 through a spherical buckling part 186. The first ring-shaped section 188 can be made of an elastic material to facilitate wearing. Alternatively, the first ring-shaped section 188 can be arranged in a buckle structure to facilitate size adjustment and more stable wearing. The positioning seat 182 is in an integral structure with the first control member 11 or is fixed on the first control member 11. The first control member 11 cooperates with the second control member 12 to control the five control switches.
[0034] Embodiment 5 As shown in Figure 14 and Figure 15 The difference between the embodiment 3 and the embodiment 5 is that the first control member 11 is provided with a special glove 180. The special glove 180 is provided with an elastic buckle hole 184 at the thumb. The elastic buckle hole 184 is partially designed to be thickened. The positioning seat 182 is arranged to be buckled with the elastic buckle hole 184 through a spherical buckling part 186.
[0035] Embodiment 6 The control method of the oral anesthesia booster instrument. Under the first interface, the first control switch 21 outputs a bolus injection instruction after being triggered, and the second control switch 22 outputs a backflow instruction after being triggered. Under the bolus injection or backflow interface, the fourth control switch 24 outputs an acceleration instruction after being triggered, the fifth control switch 25 outputs a deceleration instruction after being triggered, and the third control switch 23 outputs an emergency stop instruction after being triggered.
[0036] In an implementation, under the first interface, the first control switch 21 triggers once to output a slow bolus injection instruction, the first control switch 21 triggers twice in succession within one second to output a fast bolus injection instruction, and the first control switch 21 triggers once to trigger the second control switch 22 within one second to output a periodontal membrane bolus injection instruction.
[0037] As shown in Figure 16 and Figure 17 The oral anesthesia booster uses an nRF52832 single-chip microcomputer, and the driving member is a motor and a screw rod cooperating to realize the change from rotation to linear motion. The linear motion of the push rod driven by the screw rod pushes the piston of the pen core with a large torque to realize booster injection. The motor speed regulation adopts PWM control, and the system will adaptively change the PWM duty cycle according to the load change during injection to realize uniform injection. The motor is designed with a built-in encoder that can accurately feedback the real-time running position of the motor, thereby achieving accurate dose control. The oral anesthesia booster can be provided with multiple key form control switches to realize forward injection and backward withdrawal, as well as confirmation, return, power on, volume, directory, up, down, add, and subtract function key switches. The frequently used ones can be controlled through the first control member 11 and the second control member 12. The first control member 11 and the second control member 12 can control five key switches, so that a circuit diagram can be designed with five control switches. One control switch is provided for each of INJECTION forward injection and EXTRACT backward withdrawal, one control switch is provided for each of UP and DOWN parameter adjustment, and one control switch is provided for MOOD directory or cross-section switching and confirmation. A switch-off function can also be additionally realized by long pressing.
