Description

[0001] ASSISTANT GRIP FOR SYRINGE WITH PRESSING FORCE MEASUREMENT [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auxiliary grip for a syringe, and more particularly, to an auxiliary grip for a syringe which can be removably installed in a cylinder of a syringe for the convenience of the user.

Generally, a syringe-type cylinder is composed of a main injection unit filled with a solution (hereinafter referred to as a "barrel") and a piston for pushing and discharging a solution filled in the barrel. Such a syringe type cylinder is generally used for the purpose of treating a patient in a hospital, but recently it is used not only for the beauty of the user but also in various industrial fields.

Such a prior art related to a syringe-type cylinder is disclosed in Japanese Patent Application Laid-Open No. 2008-0104570 entitled " Disposable syringe capable of injecting a certain amount of chemical solution ". The syringe according to the prior art comprises an inner ring projection formed on the inner peripheral surface of the barrel and a plunger assembly composed of a rod reciprocating the packing along the inner peripheral surface of the barrel, .

Here, in the conventional syringe, when the packing moved along the inner circumferential surface of the barrel is caught by the inner ring protrusion, the user applies a pressure greater than the pressure that the packing was supposed to move without being caught by the inner ring protrusion. That is, when a large pressure is applied in a state where the packing is hooked on the inner ring projection, the packing passes through the inner ring projection which is caught. However, since the packing has to be adjusted to reduce the large pressure applied to the packing after passing through the inner ring projection, there is a problem that the user requires a lot of proficiency because it depends on the feeling of its pressure only.

As described above, in the case of the novice, the above-described pressure control is not easy, and even when the pressure is not controlled, the packing is continuously applied with a large pressure, .

In addition, since the user relies only on the sensation of the pressure applied to the packing, it is difficult to finely adjust the movement distance of the packing, and it is difficult to control the injection speed of the chemical liquid finely.

On the other hand, JP-A-10-1707475 discloses a " syringe metering device "as another conventional prior art related to a syringe-type cylinder. The dosing device according to the prior art is characterized in that it is connected to a syringe including a piston to adjust the injection amount of the drug. However, the elastic rib part for controlling the injection amount of the drug is also formed by a structure in which it is caught in the recessed / There was the same problem as described.

More specifically, it is an object of the present invention to provide an auxiliary grip for a syringe which can visually identify a measured value of the pressing force applied to the piston rod and can measure the pressing force of the piston rod so that the pressing force can be easily adjusted.

Another object is to provide an auxiliary grip for a syringe which can recognize a set pressure range according to the pressing force applied to the piston rod.

Another object of the present invention is to provide an auxiliary grip for a syringe which is capable of measuring a pressing force capable of detecting whether or not a charged liquid filled in a barrel is leaked.

Another object is to provide an auxiliary grip for a syringe which is capable of measuring a pressing force capable of preventing a piston rod coupled to a barrel from separating from a barrel.

Another object is to provide an auxiliary grip for a syringe which is capable of measuring a pressing force capable of guiding the piston rod coupled to the barrel to be lifted straight along the longitudinal direction of the barrel.

In order to achieve the above object, an auxiliary grip for a syringe capable of adjusting the pressure of a rod according to the present invention is an auxiliary grip mounted on a syringe composed of a barrel forming a flange and a piston rod coupled to the barrel, A wing is provided and an inlet and an outlet through which the connecting flange of the barrel is detachably connected are provided at the center of one side and the piston rod is passed through the center of the upper side so as to be connected to the inside of the barrel A body having a through hole in a shape of a hole to be formed; And pressing force measuring means provided on both sides of the body for measuring a pressing force applied to the piston rod by the user in a grip state for use of the syringe.

The pressing force measurement means may include a PCB substrate provided inside the wing; A battery provided inside the wing for supplying power to the PCB substrate; A load cell disposed under the wing in a state of being electrically connected to the PCB substrate and measuring a supporting force of a finger supporting a lower portion of the wing corresponding to a pressing force of a finger pressing the piston rod; And a display provided on the wing in a state of being electrically connected to the PCB substrate, wherein the display identifies the measured value measured by the load cell.

The auxiliary grip may further include light emitting means for emitting light with a predetermined color corresponding to a pressure range that matches the measured value of the load cell and the pressure range stored in the PCB substrate.

The light emitting means may include an LED lamp electrically connected to the PCB substrate and emitting light in a state that the LED lamp is disposed on an upper side of the wing; A comparison unit for comparing the measured value of the load cell with a stored pressure range of the database unit and transmitting an operation signal corresponding to a matching pressure range, And an operation module that controls the LED lamp according to an operation signal transmitted from the operation module.

The auxiliary grip may further include leakage sensing means for sensing a state in which the solution filled in the barrel leaks to the outside of the barrel in a state where the piston rod is coupled to the barrel.

The leakage sensing unit may include a seat disposed on the connection flange of the barrel to sense whether the solution filled in the barrel is leaking. And a hollow that is fixed to the connection flange in a close contact state and has a diameter corresponding to a cross-sectional diameter of the piston rod, And a transmission cap made of a transparent material so as to be sensed.

The transmission cap is fixed to the connection flange of the barrel in a state in which the sheet is fastened to the barrel while being fastened to the through hole of the body, thereby fixing the connection flange in close contact with the body.

In addition, the auxiliary grip may further include a release preventing member for preventing the piston rod coupled to the barrel from being separated from the barrel.

Preferably, the release preventing member comprises a slider provided on the through-hole penetrating from the one side of the transmission cap to slide along the longitudinal direction of the through-hole.

When the piston rod is coupled to the barrel and the one end of the piston rod is moved to the inside of the hollow by the user, The piston rod can be prevented from being separated from the barrel.

According to the auxiliary grip for a syringe capable of measuring the pressing force according to the present invention, since the pressing force applied to the syringe during the use of the syringe can be numerically confirmed through the pressing force measuring means, the pressing force applied to the piston rod can be easily controlled. Thereby, the speed at which the piston rod is moved forward along the longitudinal direction of the barrel can be kept constant. That is, when a solution filled in the barrel is injected, a certain amount of solution can be continuously injected, and the injection amount can be finely adjusted.

Since the pressing force measurement means is provided on both sides of the auxiliary grip, the pressing forces applied to both sides of the auxiliary grip can be compared with each other when using the syringe, so that it is possible to prevent the auxiliary grip from tilting toward one side. That is, it is possible to keep the inclination of the syringe being used as it is according to the same pressing force applied to both sides of the auxiliary grip. Therefore, during use of the syringe, the syringe can be prevented from deviating greatly from the designated position, thereby preventing a problem that may occur in the medical part or the manufacturing part.

Further, since the pressing force applied to the syringe through the light emitting means is recognized so as to be able to be distinguished step by step, the pressing force applied when the syringe is used can be more easily adjusted.

In addition, since the leakage of the solution filled in the barrel can be detected through the leakage detection means, it is possible to determine whether the syringe is defective or whether a solution filled in the barrel is provided.

In addition, the leak detecting means can be easily fixed to the flange of the barrel by simple fastening of the permeable cap fastened to the body.

Further, as the transmission cap is fastened to the body, the test strip is fixed to the flange of the barrel, and at the same time, the flange of the barrel is fixed to the body. That is, since the syringe and the auxiliary grip are integrally coupled to each other, the syringe does not swing between the syringe and the auxiliary grip, so that the use of the syringe is very easy.

In addition, when the piston rod is pulled in order to fill the solution inside the barrel by preventing the piston rod coupled to the barrel from being detached from the barrel through the release preventing means, even if the pulling force of the piston rod is excessively applied, Can be easily prevented from being separated from the barrel, thereby preventing a problem that the solution filled in the inside of the barrel can be poured to the outside of the barrel in advance.

In order to use the syringe 10 more conveniently, the auxiliary grip 100 described below may be coupled to the connection flange 20a of the barrel 20 in the present invention. Particularly, in the present invention, the syringe 10 can be more easily used through the pressing force measuring means 130 provided in the auxiliary grip 100, which will be described below.

The auxiliary grip 100 includes a body 110 and a pressing force measuring means 130 as shown in Fig.

2, the body 110 is provided with a wing 111 protruding on both sides thereof. The body 110 has a barrel 20 (see FIG. 2) And the piston rod 30 passes through the inlet port 113 so as to be coupled to the inside of the barrel 20 in a state that the piston rod 30 passes through the center of the inlet flange 20a. Through holes 115 communicating with the through holes 115 may be provided.

The body 110 is formed with a seating seat 113a in which the lower end of the connecting flange 20a is seated inside the entrance 113 and a hole in which the barrel 20 is inserted into the seating seat 113a A fitting hole 113b may be provided. The fitting hole 113b may have an opening having a diameter corresponding to the diameter of the barrel 20 and a width smaller than a diameter of the barrel 20 in the direction of the entrance 113. Accordingly, the body 110 is connected to the barrel 20 inserted through the opening 113, that is, the opening, and the connection flange 20a of the barrel 20 is seated on the seating sheet 113a, And may be disposed at the other end where the connection flange 20a is formed.

As such, the ancillary grip 100 may be removably mounted to the connection flange 20a portion of the barrel 20 and may be removably attached to the body (not shown) The index finger and the stop finger are disposed on the wing 111 provided on both sides of the piston rod 110 and the thumb is disposed on the pressure plate 33c of the piston rod 30. [

The pressing force measuring means 130 is for measuring the pressing force of the user who grips the syringe 10 on which the auxiliary grip 100 is mounted as described above and includes a PCB substrate 131, A load cell 133, a load cell 135, and a display 137.

The PCB substrate 131 is configured to apply electric power to a load cell 135 and a display 137 to be described later and can be configured to have a general structure in which a circuit is printed on a board such that electric power supplied from a battery 133 have.

Meanwhile, the PCB substrate 131 may be provided with an operation module 153.

The operation module 153 is configured to control a light emitting unit 150 to be described later and may be mounted on one side of the PCB substrate 131 as shown in FIG. The operation module 153 includes a database unit 153a, a comparison unit 153b, and a control unit 153c.

The database unit 153a has a configuration in which a set pressure range is stored, and a pressure range can be set in advance through a separate setting. For example, the database section 153a may be configured with a first pressure range as a reference, a second pressure range having a pressure range lower than the first pressure range, and a third pressure range having a pressure range higher than the first pressure range .

The comparison unit 153b compares the measured values of the load cell 135 with the measured values of the database unit 153a and a load cell 135 described later, 3, it is possible to transmit an operation signal belonging to the range to the controller 153c to be described later. For example, when the measured value of the load cell 135 corresponds to the first pressure range, the comparator 153b transmits a first operation signal to the controller 153c. When the measurement value of the load cell 135 corresponds to the second pressure range, And transmits the third operation signal to the control unit 153c when the third pressure range is satisfied.

The control unit 153c controls the LED lamp 151 to be described later and applies power to the LED lamp 151 according to the operation signal transmitted through the comparison unit 153b to cause the LED lamp 151 to emit light . For example, when the first operation signal is received through the comparison unit 153b, the controller 153c controls the LED lamp 151 to emit green light. When the second operation signal is received, the LED lamp 151 emits blue light And when the third operation signal is received, the LED lamp 151 can be controlled to emit red light.

The battery 133 is configured to provide power to the display 137, the load cell 135, or the LED lamp 151, which will be described later. The battery 133 is mounted on one side of the PCB substrate 131 as shown in FIG. . The battery 133 is a typical configuration, and a detailed description thereof will be omitted.

The load cell 135 measures the pressing force applied to use the syringe 10 and is connected to the wing 111 of the body 110 in a state of being electrically connected to the PCB substrate 131, Respectively. The load cell 135 is exposed in a state where it is disposed at the lower portion of the wing 111 and the index finger and the stop finger for gripping the syringe 10 as shown in Fig. have. As a result, the load cell 135 can be consequently supported by the index finger and the stop finger of the user. That is, the load cell 135 measures the supporting force of the index finger and the stop finger, which support the lower portion of the wing 111, corresponding to the pressing force of the thumb that presses the piston rod 30 to be described later for use of the syringe 10 can do.

The display 137 is configured to display the measured value (bearing force) measured from the load cell 135 described above and is electrically connected to the PCB substrate 131 as shown in FIG. (Not shown). The display 137 may be disposed at an upper portion of the wing 111, and may externally expose a screen capable of numerically displaying a measured value. Accordingly, the display 137 can display the measurement value measured through the load cell 135 in a numerical value for the user to confirm.

Therefore, the pressing force measuring means 130 measures the pressing force of the thumb finger pressing the piston rod 30 during the use of the syringe 10 through the supporting force of the index finger and the stop finger corresponding to the pressing force of the thumb pressing the piston rod 30 The pressing force can be indirectly measured. That is, at the time of using the syringe 10, the pressing force of the thumb, which presses the piston rod 30 through the pressing force of the index finger and the stop finger (hereinafter, referred to as pressing force) through the pressing force measuring means 130, It is possible to keep the pressing force of the piston rod 30 constant, whereby the injection rate of the solution filled in the barrel 20 can be kept constant.

Since the pressing force measuring means 130 can compare the pressing force of the index finger and the stop finger with each other, the user can adjust the pressing force applied to the load cell 135 equally. Accordingly, when the syringe 10 is used, the auxiliary grip 100 can be easily maintained in a horizontal state on the basis of the inclination of the state in which the barrel 20 is initially disposed. That is, when the syringe 10 is used, since the inclination of the barrel 20 can be maintained in the used state, the direction in which the syringe 10 is directed can be maintained, and furthermore, It is possible to prevent the problem that may occur in the medical part or the manufacturing part due to the flow of the syringe 10 in advance.

Meanwhile, the auxiliary grip 100 for a syringe capable of measuring the pressing force according to the present invention may further include a light emitting unit 150.

The light emitting means 150 includes a LED lamp 151 and an operation module 153. The LED lamp 151 and the operation module 153 are configured to emit light in predetermined colors according to the measurement values of the load cell 135 described above.

The LED lamp 151 is configured to emit light. For example, the LED lamp 151 has a structure of an LED lamp 151 including three colors, and may emit green, blue, and red light. The structure of the LED lamp 151 including multiple colors is conventional, and a detailed description thereof will be omitted.

The LED lamp 151 may be electrically connected to the PCB substrate 131 as shown in FIG. 3 and may be provided on the wing 111 of the body 110, respectively. The LED lamp 151 may be disposed at an upper portion of the wing 111 and may be exposed to the outside. Accordingly, the LED lamp 151 can easily emit light that can be discerned by the user to the outside of the wing 111.

The operation module 153 has the structure described above with reference to the PCB substrate 131, and a detailed description thereof will be omitted.

Accordingly, the light emitting unit 150 can emit light in any one of green, blue, and red colors through the LED lamp 151 according to the flow of the operation module 153. That is, since the light emitting means 150 expresses the measurement value measured by the load cell 135 in the color within the set pressure range, the user can easily control the intensity of the pressing force for pressing the piston rod 30 . As a result, the user can more easily adjust the intensity of the pressing force using the syringe 10.

Meanwhile, the auxiliary grip 100 of the syringe capable of measuring the pressing force according to the present invention may further include a leakage sensing means 170.

The leakage detecting means 170 is configured to detect a state in which the solution filled in the barrel 20 leaks to the outside of the barrel 20 in a state where the piston rod 30 is coupled to the barrel 20, The structure is such that the solution charged in the barrel 20 is leaked to the connecting flange 20a through the opening of the barrel 20 through the packing portion 31 of the piston rod 30, And a transmission cap 173.

The sheet paper 171 is configured to sense the solution leaking through the opening of the barrel 20, and may be formed of a circular paper having a hollow as shown in FIG. For example, the sheet paper 171 absorbs the solution leaking through the opening of the barrel 20, and the color is changed by the absorbed solution, and a detailed description thereof will be omitted.

The sheet paper 171 may be placed on the connecting flange 20a of the barrel 20 as shown in Fig. The sheet 171 can be fixed through a transparent cap 173, which will be described later, together with the transparent cap 173.

The transmission cap 173 is configured to fix the sheet paper 171, and may have a hollow cylindrical shape as shown in Fig. The transmission cap 173 can be integrally coupled to the body 110 through a structure in which a male thread formed on the outer circumferential surface is screwed to a female thread formed on the inner circumferential surface of the through hole 115 of the body 110 . The lower end of the transmission cap 173 is seated on the connection flange 20a of the barrel 20 while the transmission cap 173 gradually enters the lower portion of the through hole 115 through the above- It is possible to contact the surface of the sheet paper 171 and fix the sheet paper 171 in close contact with the connection flange 20a.

The transmission cap 173 is fixed to the upper portion of the connection flange 20a and the connection flange 20a is fixed to the seating sheet of the body 110 as shown in FIG. 113a. The transmission cap 173 can integrally fix the connection flange 20a of the barrel 20 and the body 110 to prevent the barrel 20 or the body 110 from rocking.

Here, the transparent cap 173 is preferably made of a transparent material. This is to allow the user to visually confirm the sheet 171 with the transparent cap 173 in a state where the sheet 171 is fixed. Accordingly, the user can easily determine whether the sheet 171 is discolored through the transmission cap 173.

Meanwhile, the auxiliary grip 100 of the syringe capable of measuring the pressing force according to the present invention may further include the release preventing member 190.

The release preventing member 190 is configured to prevent the piston rod 30 coupled to the barrel 20 from being separated from the barrel 20 and is formed in the shape of a bar having a predetermined length as shown in FIG. And a slider that is slidably moved along the longitudinal direction of the through hole 173a passing through the hollow of the transmission cap 173 from one side of the transmission cap 173 as shown in FIG. For example, the separation preventing member 190 may be formed at one side with a groove 191a so as to be easily moved along the longitudinal direction of the through passage 173a by the user, 173b may be formed.

4, when the one end of the release preventing member 190 is moved by the user into the hollow of the transmission cap 173 along the longitudinal direction of the through passage 173a, The piston rod 30 can be easily prevented from being separated from the barrel 20 as the support plate 33a of the piston rod 30 is caught by one end of the release preventing member 190. [

On the other hand, when one end is moved to the inside of the hollow as described above, the release preventing member 190 can be brought into a state in which one end is in surface contact with a part of the connecting rod 33b of the piston rod 30 have. In this case, the slider may guide the linkage 33b, which is moved along the longitudinal direction of the barrel 20, to move in a straight line along the longitudinal direction of the barrel 20. That is, the slider can prevent the inclination of the piston rod 30 moving along the longitudinal direction of the barrel 20 from being deformed.

Thus, the release preventing member 190 can detachably couple the piston rod 30 to the barrel 20 via the slider, and can easily prevent the inclination of the piston rod 30 from being deformed .

Meanwhile, the auxiliary grip 100 for a syringe capable of measuring the pressing force according to the present invention may be provided with a grip portion 117 extending to the lower end.

The grip portion 117 has a configuration corresponding to the fitting hole 113b of the body 110 as shown in FIG. 5, and is configured to grip the solution when the solution is filled in the accommodation space of the barrel 20, And a rib protruding in the longitudinal direction of the body 20. The grip portion 117 may be provided with a slip preventing member 117a for preventing the slip of the finger on a part of the outer circumferential surface. Accordingly, the gripper 117 can be in a state of wrapping a part of the upper portion of the barrel 20 as shown in Fig.

Thus, when gripping the solution into the receiving space of the barrel 20, the grip portion 117 supports the grip portion 117 with the thumb and the index finger of one hand, The rod 30 is pulled out. The user grips the grip portion 117 located at the upper portion of the barrel 20 and thus the handle 23 provided at the lower side of the barrel 20, that is, the position adjacent to the injection needle, It is possible to prevent the occurrence of an accident that the needle is stuck to the needle when gripped.
