Description

AUTOMATIC DETECTING AND PREWARNING SYSTEM FOR MEDICINE INSTILLER}

The present invention relates to an automatic detection and prophylactic system of drug droppers, wherein the drop carrier is axially connected to a lever located in a flow indicator cylinder below the drug dropper of the drug dropper. The drug falls at a predetermined rate in the drug dropper, or flows in a reciprocating manner, affecting the drop carrier. Therefore, the detection medium of the system is cut off as a control signal intermittently sent to the alarm medium. When abnormal dripping speed or flow continues for a preset time, the alarm medium can automatically send a warning.

Drug drops are often used as a medical treatment. The normal drip rate and remaining volume of the drug routinely dispensed is visually diagnosed by the caregiver. There is also now an electronic device that controls the dosing, time, and drip flow of drugs. However, these electronic devices are generally for high capacity use and are expensive in terms of price. This applies only to specialty medications that require special attention to drip time and flow and are typically used only in medical institutions.

Also developed are sensor circuits for plugging directly into a medicine bag or bottle containing the drug being dispensed and a sensor needle connected to the alarm medium. Since the sensor needle must be in contact with the drug in order to operate, there is a processing problem to meet the sanitary requirements.

The invention entitled "Method and Apparatus for Monitoring the Level of Contents in a Container" was published by the EP 30 May 1990 publication number EP370604A. However, published monitors and methods for monitoring the level of contents in a container are quite inconvenient to use.

US Pat. No. 6,337,631 B1, licensed to the same applicant of the present invention, has released an alarm system that can automatically alert when the drug is dispensed. However, this patented design still has some improvement.

The main purpose of the present invention is to provide an automatic detection and pre-warning system of the drug dropper, which includes a forceps which can be easily clamped on the flow indicator cylinder of the drug dropper, a detection medium in the form of an electronic sensor installed in the forceps, and a conductor. There is an alarm carrier connected to the detection medium and a drop carrier connected to the lever located in the flow indication cylinder under the drug dropper. After a fixed number of drops or flows per minute are set in the drug dropper, the drug is input to the alarm medium, and the drug is subsequently dropped from the drug dropper, shocking the drop carrier, causing it to shake repeatedly, intermittently as a control signal to the alarm medium. Block the detection medium. If the number of drops or flow of abnormal drug per minute continues during the preset time, this may be due to the tube of the drug dropper being compressed or bent, the drug container empty, etc., and the alarm medium may automatically emit a warning. have.

Another object of the present invention is to provide an automatic detection and pre-warning system of the drug dropper, where a fixed number of drops or flow per minute of the drug dropper is detected and calculated and entered into the alarm medium of the system. The current available electronic control technology can then be used to determine when the dispensed drug is used up. This function allows the caregiver to watch multiple drug droppers at the same time, achieving effective control and ward management and high efficiency nursing work.

Hereinafter, in order to be described in detail so that those skilled in the art can easily implement the present invention, the most preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. . Other objects, features, and operational advantages, including the object, operation, and effect of the present invention, will become more apparent from the description of the preferred embodiment.

Referring to FIGS. 1,2 and 3, in which the automatic detection and pre-warning system of the drug dropper according to the implementation of the present invention is shown, the drug dropper 50 generally contains a drug container 51 containing a drug, a transparent flow. There is an indication cylinder 52, a tube 53, a flow controller 54 and a syringe 55. The system of the present invention includes a forceps 10, a detection medium 20 provided on the forceps 10, an alarm medium 30 connected to the detection medium 20, and a drop carrier shaking medium 40. The tongs 10 are adapted for picking up on the flow indicator cylinder 52 at a predetermined position without being later compressed or deformed.

The tongs 10 may be designed differently to make it easier to pinch and remove the flow indicator cylinder 52 for repeated use. In the integrated body of the present invention described in Figure 1, the forceps 10 is a pair of two tongs of the elastic holding part 11 of the appropriate size. The two object catching portions 11 each have an outwardly bent portion 12 so that the bent portion 12 can properly clamp the outer surface of the flow indication cylinder 52. The two horizontal markers 13 hold two object holding portions so that the forceps 10 can be easily positioned on the flow indicator cylinder 52 without disturbing the caregiver looking at the internal state of the flow indicator cylinder 52 ( 11) are provided correspondingly to the end.

The detection medium 20 is installed at the two object catching portions 11 of the forceps 10, and is designed according to general infrared radiation and sensitization principles. In addition to infrared light, magnetic fields, lasers and the like are also used in the detection medium 20. The detection medium 20 has a radiator 21 and a receiver 22, which are separated and correspondingly located on the inner side of the bent part 12 of the two object catching part 11 of the forceps 10. When the tongs 10 clamp the transparent flow indicating cylinder 52, the radiator 21 and the receiver 22 are spaced by the transparent flow indicating cylinder 52 as shown in FIG. At the location depicted above, the detection medium 20, with the emitter 21 and the receiver 22, provides a detection function using light rays or transmitted wavelengths directly from the emitter 21 to the receiver 22. The marker 13 mentioned above is at the end of the two object catching part 11 of the tongs 10 corresponding to the radiator 21 and the receiver 22.

The alarm medium 30 has an electronic control circuit internally. This electronic control circuit is controlled via a switch 31 external to the alarm medium 30. The external screen 32 displays relevant data for the caregiver to refer to in the operation and monitoring of the automatic detection and advance warning system of the present invention.

2 is an enlarged perspective view showing the internal structure of the flow display cylinder 52 in parts. The flow indicator cylinder 52 has a drug dropper 521 and an upper lid 522, and liquid flows down into the cylinder 52 through the center of the drug dropper 521. The drop carrier shake medium 40 is arranged in such a way as to be positioned at a fixed height in the cylinder 52 at the bottom of the drug dropper 521 in the flow indicator cylinder 52.

As shown in FIG. 3 in which the drop carrier shake medium 40 is exploded and enlarged, the drop carrier shake medium 40 includes a lever structure 42 capable of tilting the drop carrier 41 and the drop carrier 41. The drop carrier 41 and lever structure 42 may be designed differently to provide equivalent functionality. Referring to the drop carrier shake medium 40 shown in FIG. 3, the lever structure 42 has an inverted T-shaped holder 421 with a vertical support pointing downwards from the bottom of the upper lid 522 of the flow indicator cylinder 52. There is). The horizontal shaft 422 is connected to the lower end of the vertical support, and the drop carrier 41 is a prefabricated disc of a suitable size to fit into the cylinder 52. The drop carrier 41 has two side-by-side symmetrical positions of the shaft hole 411 on one side near the top, and the horizontal shaft 422 is fitted into the shaft groove so that the drop carrier 41 can tilt. Make it work. Note that the vertical support of the inverted T-shaped holder 421 is in a position off the center of the upper lid 522. The horizontal lever 422 is also at a position off the center line of the flow indicating cylinder 52. The shaft hole 411 is on one side of the drop carrier 41 corresponding to the offset lever structure 42. The drop carrier 41 is located at the center of the cylinder 52. Therefore, the radius of the drop carrier 41 in which the horizontal lever 422 of the lever structure 42 is located and the opposite part are different from each other. The drop carrier 41 is provided on the outer surface of the shaft hole 411 above the drop carrier 41 so that the drop carrier 41 is horizontally balanced in proportion to the inverted T-shaped holder 421 without tilting near the horizontal lever 422. There is a weighted portion 412.

Also in the center of the drop carrier 41 is a recess 413 that can accept the force of a drop of drug falling from the drug dropper 521. And between the two shaft holes 411 is a stop plate 414 upward. As the drug falls off the drug dropper 521 and impacts the center of the concave portion 413 located in the larger radius portion of the drop carrier 41, the drop carrier 41 tilts near the horizontal lever 422. At this time, the larger radial portion of the drop carrier 41 is inclined downward to block the path between the radiator 21 and the receiver 22 of the detection medium 20. When the drop carrier 41 is tilted near the horizontal lever 422, the stop plate 414 is against the vertical support of the inverted T-shaped holder 421 so that the drop carrier 41 does not tilt completely vertically.

In the lever structure 42 the horizontal shaft 422 is used as an axis lever for tilting the drop carrier 41. However, another design may be employed as the lever structure 42. For example, a shaft rod designed in two radial directions may be provided at two opposite opposite points of the inner wall of the flow indication cylinder 52, and the drop carrier 41 is opposite to the two opposite opposites. It may be provided to engage the two axis rods of the cylinder 52 with corresponding tubes at the points.

Referring to FIG. 4, when no drug is dropped from the drug dropper 521 to the drop carrier 41 in the system of the present invention, the drop carrier 41 is level in the flow indicator cylinder 52. At this time, the radiator 21 and the receiver 22 of the detection medium 20 are not insulated from each other. And the electronic control circuit inside the alarm medium 30 is set to an inoperative state.

Drug droppers are known to be used to control the rate of drug injected into a patient, and the rate of drug injection is controlled by flow controller 54. As in most cases, the infusion rate is set and controlled by the number of drops per minute, such as 6 drops per minute or 8 drops per minute. If infusion is started through the drug dropper after the number of drops per minute is set via flow controller 54, the drug drops off the drug dropper 521. That is, the drug drops intermittently from the drug container 51 into the flow indicator cylinder 52. The intermittent dropping drug drops to a longer radius of the drop carrier 41, and the dropping force of each drop causes the drop carrier 41 to tilt near the lever structure 42, as shown in FIG. A wider part likewise tilts down. The larger radius of the inclined drop carrier 41 is now located between the radiator 21 and the receiver 22, insulates the two elements from each other and cuts off the detection medium 20. For example, this is to stop the infrared wavelength from which the inclined drop carrier 41 is transmitted from the emitter 21 to the receiver 22.

If the infusion through the dropper is set to be fixed at a dropping rate of 6 to 8 drops per minute, one interval between two drops falling in succession is the first drop of drug falls into the drop carrier 41 and the drop carrier is shaken and tilted, The moment the flow stops, it is enough time for the inclined drop carrier 41 to return to the horizontal state before the second drug drop falls. This means that the drop carrier 41 shakes and tilts intermittently and reciprocally. The radiator 21 and the receiver 22 are insulated from each other by a fixed number of times by the drop carrier 41 intermittently. In a given retrieval state, this form of intermittent insulation forms a signal that periodically repeats opening or closing in the detection medium 20. The number of drops falling per minute to the drop carrier 41 by the design of an electronic control circuit of the alarm medium 30 based on a signal that periodically repeats the closing and opening in the detection medium 20 is estimated by the flow per minute. It is automatically detected, calculated, or switched to the value or number of drops dropped in the drug (because each drop is usually the same amount). The default value is set as the detection standard and is displayed on the screen 32 of the alarm medium 30.

When the automatic detection and pre-warning system of the present invention is set to a fixed drop rate and fixed drop number of drug per minute and used for dropping, if the detection medium 20 finds an abnormal situation in the falling drop number or flow of the falling drug, This may be because the tube 53 is compressed or bent to stop the flow, the flow controller 54 is improperly adjusted, or the drug container 51 is empty. And for a certain period of time the drug does not return to normal. For example, if one minute is set in the electronic control circuit and an abnormal state exceeds this, the alarm medium 30 automatically sends a warning. Unlike the present invention, the conventional drug dropper warning system only issues a warning when the drug container 51 is empty.

The system of the present invention is dispensed with a drug dropper and a standard drop number or flow of drug per minute is set in the alarm medium 30 to detect a fixed number of drops and flow of drug per minute, 51) the dosage is generally indicated so that the time point at which the drug being dispensed is exhausted can be set in advance with the system of the present invention, which is made up of more advanced electronic control technology. The time value preset before using the system of the present invention is entered into the alarm medium (30) or shown on the screen (32) before the system of the present invention starts. As such, the caregiver can simultaneously watch several drug drops without negligence at the time when each individual drug container 51 may be empty. Therefore, care in the patient ward can be carried out and controlled efficiently and effectively.

The alarm medium 30 is connected to the detection medium 20 via a conductor and its length is appropriately determined according to the actual needs. The alarm medium 30 may be designed as a buzzer or loudspeaker to emit musical sounds or voices, or as a light emitting device such as a light bulb to emit light or rays. Alternatively, an infrared (RF) or radio frequency (RF) transmission system can be used to transmit warning signals to other remote alarms or nursing stations for the most efficient patient care. According to the currently available electronic control technology, the design of such internal circuits and wiring of the detection medium 20 and the alarm medium 30 for the detection and setting of the number of drops and flow of drug per minute is a commonly viable technique. More details are not discussed here.

Above, according to the above-described automatic detection and preventive system of the drug dropper according to the present invention, the drop carrier is connected to the axis of the lever located in the flow indicator cylinder below the drug dropper of the drug dropper so that the drug is pre-set in the drug dropper It drops at a speed or flows in a reciprocating manner, affecting the drop carrier. Thus, the alarm medium can automatically alert when the detection medium of the system is interrupted as a control signal sent to the alarm medium intermittently and abnormal dripping speed or flow continues for a preset time.

For reference, the embodiments disclosed herein are only presented by selecting the most preferred embodiment in order to help those skilled in the art from the various possible examples, the technical spirit of the present invention is not necessarily limited or limited only by this embodiment In addition, various changes, additions and changes are possible within the scope without departing from the technical spirit of the present invention, as well as other embodiments that are equally clear.
