Description

ELECTRONIC ASPIRATOR

The present invention relates to a drainage system for continuously collecting body fluids by using a low vacuum pressure by a vacuum pump, and more particularly, to an electromagnetic type aspirator which can safely carry and move freely without cross contamination of a vacuum pump .

BACKGROUND ART [0002] As a drainage system for discharging a body fluid in a body during surgery or after surgery, there is well known a device for continuously collecting body fluid by using a low vacuum pressure. The device includes a hand or electric vacuum pump generating a low vacuum pressure, a body fluid container, and a generally elongated suction conduit inserted into the body through the body of the patient. Wherein the body fluid container is connected between the vacuum pump and the conduit, and is used after being cleaned, reused, or preferably used once. When the vacuum pump is operated, negative pressure is applied to the body fluid container, and the body fluid is forced to be sucked and discharged through the conduit. Body fluids discharged to the outside of the body are collected in a body fluid container. The body fluid container filled with body fluids is washed and then reused, preferably disposable.

Such a drainage system is fixed and mobile, and a mobile type is preferable for convenience and restoration of a patient who can be moved. However, the conventional portable drainage system only allows the patient's behavior to be limited. Particularly, since there is a lack of safety such as discomfort for collecting the body fluid container and cross contamination of the pump side equipment, .

The so-called 'drain pump unit' disclosed in the following patent document 1 includes a body fluid collection container detachably attached to a pump housing, and a connection unit capable of being connected to a patient side drain pipe and a body fluid collection container do. That is, when the body fluid collecting container is emptied or replaced, only the body fluid collecting container can be easily removed without separating the drain tube.

The following Patent Document 2 proposes a method for appropriately controlling the operation of the vacuum pump by sensing the internal pressure of the patient and detecting the amount of drainage to inform the replacement time of the drainage collection container.

On the other hand, Patent Document 3 discloses an apparatus equipped with an ultraviolet lamp which sterilizes the extracts collected in a suction tank.

A common problem of the conventional portable drainage system including the cited references mentioned above is that since the vacuum pump side and the inside of the body fluid container are not spatially separated and are connected to each other and therefore the posture of the apparatus is greatly tilted or can not be stably maintained, Some of the body fluids collected in the container may flow into the vacuum pump side and become contaminated. In addition, if the fluid container is not replaced in a timely manner, the collected fluid may overflow and become contaminated. If the vacuum pump-side mechanism is contaminated, it can no longer be used.

As such, the conventional systems are not safe during movement due to the cross contamination problem of the vacuum pump side mechanism, which is expensive equipment, and the patient's behavior is limited, resulting in inconvenience.

The accompanying drawings are merely exemplary and are not to be construed as limiting the present invention. In addition, some elements may be exaggerated or omitted in the drawings, and may differ from actual ones.

A preferred embodiment of the present invention comprises a main body 1 and a body fluid collecting cartridge 2 as shown in Fig. The main body 1 includes a main body case 3 which is a synthetic resin injection molding and the aforementioned vacuum pump and its control circuit elements incorporated in the main body case 3.

The collar 5 formed on the upper surface of the main body case 3 can be easily carried by hanging a necklace string (not shown). The main body case 3 has a transparent window 6 on its front side and a power switch 8 provided at the bottom of the front side of the window 6 with a screen of the indicator 7 visible. A switch 9 is provided. Here, a screen of the display unit 7 is provided with a user interface in which, for example, operation and usage information such as driving and stopping of a vacuum pump, set vacuum pressure, battery remaining amount, and usage information are displayed in real time. The power switch 8 can be used, for example, to press and hold the main power to turn on and off the main power, and to start and stop the vacuum pump operation by pressing the main power switch short. The vacuum pressure setting switch 9 is a swing operation type for selectively setting the drain time and the drain operation pressure according to the patient condition or the type of body fluid to be drained.

The body fluid collecting cartridge 2 is a body in which the vacuum container 10 and the body fluid pouch 11 are integrated and detachable with respect to the main body 1 described above. The specific desorption structure will be described later. The vacuum container 10 is made of a transparent and rigid material, for example, a transparent synthetic resin injection molding. The body fluid bag 11 accommodated in the vacuum container 10 is flexible and stretchable, and preferably made of a transparent material such as PVC, rubber, or silicone. A connection conduit 12 and a body fluid outlet 13 connected to the body fluid bag 11 are drawn out through the vacuum container 10 at the lower end of the vacuum container 10. The connection conduit 12 is for connecting with a normal conduit for drainage on the body side, which is not shown in the drawing. Preferably, a common valve, a tube connector or the like not shown is used. The end of the body fluid outlet 13 is sealed with, for example, a rubber seal, so that an injection needle (not shown) can be stuck to collect the sample for examination of a component of the body fluid collected in the body fluid pocket 11 or the like.

2, the vacuum pump 4 built in the main body case 3 is connected to a hub 15 formed on the bottom of the main body case 3 through a separate tube 14, The connection pipe 16 formed in the vacuum container 10 is fitted. Between the connection pipe 16 and the inner wall surface of the hub 15 is sealed by a packing ring 17. The lid 18 at the lower end of the vacuum container 10 is only for receiving and assembling the bodily fluid bladder 11, and the periphery thereof is also hermetically fixed. The lid 18 may be configured such that it is closed with the liquid bag 11 for one time, for example, and the remaining body of the vacuum container 10 can be opened for reuse.

The vacuum pump 4 and the vacuum container 10 are spatially communicated with each other, and the vacuum container 10 forms a closed space in which the periphery thereof is blocked. Therefore, the vacuum pump 4 can be operated to apply a negative pressure to the sealed space of the vacuum container 10, and a separate vacuum pressure sensor 19 can be installed to control the sound pressure to be maintained at a constant level You can. The body fluid bag 11 accommodated in the vacuum container 10 forms a space separated from the inside of the vacuum container and when the pressure in the divided space is larger than the sound pressure acting on the closed space in the vacuum container 10, And the body fluid of the patient can be collected and stored through the drain conduit connected thereto through the connection conduit 12 in accordance with the operation.

Meanwhile, as shown in FIG. 2, a separate cartridge detection switch 20 may be installed in the main body 1. FIG. The cartridge detection switch 20 is for detecting whether or not the body fluid collection cartridge 2 is engaged with the main body 1. Any switch type or any position may be used as long as the switch is capable of generating a switching signal in its fully engaged state. The cartridge detection switch 20 can prevent, for example, a vacuum pump from operating accidentally during incomplete coupling, and can provide continuity of program control that was previously performed even when the bodily fluid collection cartridge is replaced and replaced during drainage.

3, the control circuit of the vacuum pump 4 includes a battery 31, a control unit 32, a power supply unit 33, an input unit 34, a sensor sensing unit 35, a display unit 36, , And a vacuum pump driving unit 38. The battery 31 is for power supply of the control circuit and is replaceably accommodated in the body case 3 as shown in Fig. The battery 31 may be any type of primary battery or secondary battery. The control unit 32 is programmed to instruct the operation and stop of the above-described vacuum pump 4 according to the conditions input through the input unit 34 using the processing mechanism of the microcomputer and to output the display information in real time. Program routines can be created and loaded at the normal skill level, so a detailed description thereof will be omitted for convenience. The power supply unit 33 is used to supply and manage the power required for each circuit part such as the control unit 32 from the power source of the battery 31. For example, a well-known PMIC (power management IC) can be used. The input unit 34 inputs the above-described power switch 8 and the vacuum switch setting switch 9 signal to the control unit 32. The sensor sensing unit 35 converts the analog signals of the vacuum pressure sensor 19 and the cartridge sensing switch 20 into digital data and inputs them to the control unit 32. [ The display unit 36 displays the real-time display information outputted therefrom in accordance with the instruction of the control unit 32 on the display unit 7 described above. The boosting unit 37 is for boosting the voltage of the battery 31 to a voltage required for driving the vacuum pump 4 and can use, for example, a well-known booster and a flyback converter. The vacuum pump driving unit 38 interrupts the voltage applied through the voltage step-up unit 37 in response to the command from the control unit 32. Each part of the control circuit is well known in the field of driving a vacuum pump, and can be easily implemented, so that detailed description will be omitted for the sake of convenience.

4 is one of the program control routines of the control unit 32 described above for maintaining the negative pressure acting on the closed space in the vacuum container 10 of the vacuum pump 4 constant. That is, when the vacuum pressure and the operating time by the user are initially set (step S1) while the power is applied, the vacuum pump driving (step S4) is started while the set operating time is counted (Step S4) on the basis of the vacuum pressure information inputted in real time from the vacuum pressure detector 19 through the sensor detection section 35 (step S4), and the negative pressure acting on the closed space in the vacuum container 10 It is determined whether or not the set value has been reached (step S5), and the vacuum pressure check step S4 is repeated in real time or at predetermined time intervals until the negative pressure reaches the set value. Next, when the negative pressure reaches the set value, the driving of the vacuum pump 4 is stopped (step S6), and it is judged whether or not the operating time has elapsed (step S7). If the operating time has not elapsed yet, the vacuum pressure is checked again (step S8) to compare the present vacuum pressure with the set value (step S9). If the vacuum pressure falls below the set value, the vacuum pump driving step S3 (S7) of repeating the step of determining whether the operation time has elapsed or not. On the other hand, when the operation time elapses, the program is terminated. In this way, a constant negative pressure can be applied to the closed space in the vacuum container 10.

Fig. 5 relates to a control routine for continuity of the vacuum pump operation in response to the replacement of the body fluid collecting cartridge 2 during the operation of the vacuum pump by the control unit 32 described above. That is, it is judged whether or not the body fluid collecting cartridge 2 is detached (step S11) based on the signal of the cartridge detecting switch 20 described above during the operation. If it is determined that the body fluid collecting cartridge is detached, (Step S12), and then, the signal of the cartridge detection switch 20 is used for collecting the body fluid (for example, When it is determined that the cartridge 2 is connected (step S13), the vacuum pump operation is resumed (step S13) with the use information stored in the previous step. According to such a control routine, continuity of the previous control can be achieved without newly setting the operation time and vacuum pressure after replacement of the body fluid collection cartridge. In addition, as long as the user does not stop the operation with the power switch 8, the power vacuum pump can be prevented from operating in a no-load state even if the body fluid collection cartridge is separated due to an excessive impact during use, It can be done.

Fig. 6 shows a preferred rotary attachment / detachment structure of the body 1 and the bodily fluid collection cartridge 2 described above. The engaging protrusions 41 and the engaging grooves 42 are formed on the bottom surface of the main body 1 and on the upper surface of the body fluid collecting cartridge 2 for the rotary attachment and detachment coupling structure. The engaging jaw 41 and the engaging groove 42 are formed along concentric arcs around the connecting pipe 16 of the vacuum container 10 described above. That is, the body fluid collecting cartridge 2 can be pushed into the main body 1 in the 90 ° direction as shown by a phantom line in the drawing, and then rotated clockwise to be mutually engaged, will be. The overrunning jaw 43 formed in the engaging jaw 41 and the engaging groove 42 serves to prevent a coupling error due to excessive rotation during operation during rotation.

Next, FIG. 7 shows the use of a stopper button 50 in the form of a ball stop, which is a locking device capable of preventing the main body 1 and the body fluid collecting cartridge 2 from falling off arbitrarily in the rotary detachable coupling structure shown in FIG. The stopper button 50 is provided, for example, inside one side of the engagement portion of the main body 1 and is supported by a spring 51, and the end portion thereof is rounded. The rounded end portion always protrudes out of the mounting hole 52 formed in the side surface of the main body case 3 by the spring 51. [ In the body fluid collecting cartridge 2, a fixing hole 53 corresponding to the attaching hole 52 is formed. That is, when the body fluid collection cartridge 2 is rotationally coupled to the main body 1, when the stopper button 50 is pushed inward by the body fluid collection cartridge 2 and then rotated to the engagement position, (50) is inserted into the fixing hole (53) of the body fluid collecting cartridge (2), whereby the state of engagement is stably maintained. When the stopper button 50 inserted in the fixing hole 53 is slightly pushed in the engaged and fixed state, the fixed state is released, so that the body fluid collecting cartridge 2 can be rotated and reversely rotated.
