Description

A sensing and notifying device for the low water level of ringer solution

The present invention relates to a low fluid level sensing and notification device, and more particularly, when a fluid is injected into a blood vessel when injected into a ringer (ring-gel) container or a sack container, the sound falls around the sound, The purpose of the present invention is to provide a sap low-level detection and notification device that enables the user to promptly notify the user through selected notification means such as light and vibration.

In general, the infusion of the infusion on the ringer container for injection through the blood vessel to the patient in a hospital, etc. are packaged in a quantitative unit is released so that when all the infusion is injected, it must be quickly exchanged.

Various notification devices have been disclosed in the past so that patients and guardians can quickly recognize the time of fluid exchange.

For example, Korean Utility Model Registration No. 302890 discloses a device that can notify the user of alarm and light signals by switching operation when the fluid level drops in the Ringer container. There is a problem that the blood inside can flow back, it is not practical practical use,

In addition, the Korean Utility Model Application Nos. 20-1998-19908 and 20-1999-25643 have been applied as means for detecting and notifying the remaining amount of the sap using a mechanical mechanism. When the weight in the container decreases according to the injection amount, the spring expands and when the spring reaches the predetermined position, the micro switch is turned on and the alarm sounds through the buzzer.

In the case of Korean Patent Application Nos. 10-1991-9551, 10-1996-19698 and Korean Utility Model Applications 20-2000-10177 and 10-2000-41474 using an electronic method, the oscillation principle is used. In the case of 20-2000-10177 and 10-2000-41474, the alarm is triggered by an electronic sequence using the optical transmission / reception principle of the infrared material, and in the case of Patent 1996-19698, the change of the balancing of the bridge resistance by using the strain gauge As a result, the analog method is started by taking the voltage change of the differential amplifier and generating an alarm sound when the set threshold is reached.

In Korea Utility Model Registration No. 310667, the guardian and the guardian go through the process of sensing the ringer sap by the load sensor and amplifying the micro voltage signal, converting the analog signal into the digital signal, processing by the microprocessor, and controlling by the sequence circuit. It is disclosed that a patient or nurse notifies the end of the injection by a lamp signal such as an alarm sound or LED, and applies a caution signal in the same way even when the injection is not normal, but the device is expensive. In other words, they were having problems such as being incompatible with existing sap supply devices.

In addition, the Korean Utility Model Registration No. 137734 discloses a technology that allows the alarm sound to be notified by controlling the melody plate while the switch operation is interrupted according to the height of the ringer sap using the principle of the lever, but this is merely a melody. Since the supply state of the sap is not known to patients with impaired ears and eyes, there was a problem that the effectiveness.

In addition, in Korean Unexamined Patent Publication No. 2000-0054676, the sap in the case in which the inflow and outflow holes are formed above and below the sap so that the sap flows to the syringe automatically when all the sap inside the ringer container is leaked to the outside. Float (= float) that is raised and lifted in accordance with the presence or absence to allow the float to open and close the outlet hole, this prior art is to ensure that the fluid is supplied to the blood vessel through the syringe according to the presence or absence of fluid, If it falls, it can automatically close the outflow hole to prevent air from being injected into the blood vessel, and also prevent the blood from leaking out of the patient's body, but the fluid falls and the replacement time for fluid replenishment is Known low fluid level detection and notification, including the issue of not being able to notify While some functions are useful, the patients with hearing or vision impairments cannot reach the proper time to exchange fluids due to the lack of fluid, and the manufacturing cost of the device is expensive, and it is compatible with existing fluid supply devices. There is an urgent need for the development of a low fluid level sensing and notification device that can comprehensively solve these problems.

Therefore, the present invention is applied to the existing fluid supply device as described above to prevent the air flow into the blood vessels when the fluid (or blood in the blood transfusion) and at the same time to block the blood flow of the patient, and also the surrounding To provide a guardian and patient with a low fluid level detection and notification device that can be notified immediately.

The present invention is particularly equipped with a variety of notification means for the patient to be sure that even if the guardian has a hearing, vision, etc., and also prevents the air is injected into the blood vessels, and the blood of the patient flows back from the body In addition, it can be easily installed at low cost in addition to the existing fluid supply device, and the present invention has been completed with the technical problem of designing to provide a low fluid level detection and notification device with excellent compatibility.

In addition, the shape of the float 9 is not only a spherical shape but also a substantially cylindrical shape as shown in FIG. 7E, and a lower end portion enters into the lower outlet hole 7 of the drop tube 5 to perform a closing function. It can also be configured to have wealth.

In response to the lifting and lowering operation of the float 9, a magnetic body 11 capable of magnetically sensitive to the magnetic body 10 or a magnetic sensitive material capable of being sensitive to magnetic force is provided on the switch casing 12.

That is, the switch casing 12 has a casing (14, 15) angularly bisected by the hinge pin (13) to be coupled to the lower outflow pipe (8) of the drop pipe (5) in a one-touch clamping manner. The torsion spring 16 is elastically supported, and the opposite side portions of the hinge pins 13 of the casings 14 and 15 are formed by the openings 14a and 15a, so that the hinge pins 11a are divided into rings having one side open. By installing the magnetic body 11, which is capable of adjusting the angle by injecting, the magnetic body 11 also adjusts the angle of the hinge pin 11a when the casing 14 and 15 angularly moves from the hinge pin 13 to the starting point. And the front side can be opened.

The magnetic body 11 may be configured in a roughly C-shape or the like as well as a divided ring shape.

The lower portion of the casing (14, 15) may be fixed to the magnetic body (17) that can be sensitive to the magnetic body (11) or a magnetic force sensitive material that can be sensitive to magnetic force so that the magnetic body 11 does not flow randomly when descending. have.

In addition, the switch casing 12 is provided with a switch 18 capable of controlling switching as the magnetic body 11 is lifted, and when the switch 18 is turned on, various methods such as a lamp such as an LED and a specific warning sound and vibration are provided. Through the notification means 19 is provided so as to inform the hospital personnel such as patients and guardians, nurses, doctors and the like through.

The notification means 19 may be integrally installed on the switch casing 12 as shown in FIG. 5, or may be installed on a separate casing 21 to simultaneously notify the patient and the guardian by using the cord 22. In the casing 21, the cord 22 may be connected to the notification means 19 which can be immediately notified by lighting or warning sound installed in the nurse waiting room.

In addition, the drop tube 5 may be selectively used in a variety of forms, as shown in Figure 8a, as well as the general drop tube 5, the filter 20 on the inlet 6 as shown in Figure 8b In the case of using the drop tube 5 to which the addition is made, the partition wall 23 is formed above the inside of the drop tube 5 so that the float 9 blocks the flow of the sap.

As shown in FIG. 8C, the middle portion of the drop tube 5 is formed to be concave in an annular shape to the center portion, and the float 9 on the upper side may be configured to perform the sap opening and closing operation while interlocking with the upper and lower portions. The pipe 5 itself may be configured to be screwed up and down as shown in FIG. 8D, and the outlet hole 7 may be interposed with a tubular body 7a made of a flexible rubber material in order to increase airtightness.

In the present invention, the float 9 is installed in the ringer container 2 as shown in FIG. 9, and the switch casing 12 is installed at the lower end of the ringer container 2 to operate the notification means 19. It can be done.

Reference numeral 24 in the figure shows a stand that hangs and supports the ringer container 2.

The low fluid level sensing and notification device 1 of the present invention, which can be configured as described above, is a syringe 4 on an outlet stopper 3 of a ringer container 2 that is used to inject a ringer solution into a patient. Is installed on the drop tube (5) to be coupled using the sap when the sap drops the outlet hole (7) is blocked by falling down to prevent the sap blocking and air flow into the blood vessel bar The action thereof will be described in more detail below.

The sap introduced and stored on the Ringer container (2) flows into the dropping tube (5) through the syringe (4), and the vascular phase through the outflow hole (7) and the outflow pipe (8) by quantity in the dropping tube (5). The supply of sap is done.

When the sap introduced into the ringer container 2 is exhausted, the float 9, which was introduced into the drop tube 5 and floated in the middle of the drop tube 5 due to the buoyancy acting by the sap, is dripping due to the exhaustion of the sap. The water level is lowered to the lower part of the pipe 5, and the float 9 is also lowered at the same time.

Due to the lowering operation of the float 9, the magnetic body 11 or the magnetic sensitive material inside the switch casing 12 clamped to the lower portion of the drop tube 5 is driven by the magnetic force of the magnetic body 10 embedded in the float 9. As shown in FIG. 3, the magnetic material 11 rises to turn on the switch 18 in the upper portion of the switch casing 12 so that the notification means 19 performs the notification operation around.

In addition, the float 9 is lowered from the drop tube 5 so that the lower outlet hole 7 of the drop tube 5 is closed by the magnetic force between the magnetic bodies 10 and 11 so that the fluid is supplied. When interrupted, air is injected into the blood vessel or blood flow back in the patient's body.

When a new sap is added and stored, the ringer container (2) is replaced, and the sap is dropped into the drop tube (5) again, and the level of the drop tube (5) rises, which is caused by the sap rather than the magnetic force between the magnetic bodies (10, 11). The buoyant force acts more strongly so that the float 9 is raised to the same height as the sap deposited on the drop tube 5 so that the outlet hole 7 is automatically opened and the normal supply of the sap is resumed.

On the other hand, the notification means 19 of the present invention can be installed on the switch casing 12 integrally attached or separately installed in a separate casing 21 connected to the cord 22, such as guardian and nurse waiting room, etc. You can immediately tell that the sap has dropped into place.

In addition, the present invention can be used not only for transfusion, but also for transfusions to patients at the time of surgery or at other hospitals.

As described in detail above, the infusion solution low-level detection and notification device (1) provided by the present invention is to be used in the transfusion, or blood transfusions, stored in the Ringer container (2),

The present invention is a magnetic body 10 or a magnetic sensitive material that can be sensitive to the magnetic force on the float (9) is buried in accordance with the water level is buried in the drop pipe (5) or ringer container (2) when the sap drops The magnetic body 11 or the magnetic sensitive material inside the switch casing 12 clamped at the lower end of the outlet hole 7 and the magnetic force sensitive material so as to close the outlet hole 7 by the magnetic force so that air flows into the blood vessel when the sap is exhausted. It is possible to reliably prevent lung defects, and to eliminate the problem that the patient's blood flows back outside the body, as well as various notification means such as lighting, specific warning sound, vibration, etc. 19) It is possible to promptly replenish the fluid, and especially by vibrating notification means, it is possible to inform the fluid replenishment time even for patients with visual and hearing impairment.
