A DOSIFLOW METER WITH DOSE ADJUSTMENT ACCORDING TO VITAL FINDINGS

TECHNICAL FIELD The invention relates to a device able to automatically turn off the serum by measuring vitals, i.e. pulse, the amount of oxygen in the blood, blood pressure and heart rhythm, to be taken from the patient through the sensors it incorporates, when there is a change in these values; able to add the drug to be given by the healthcare personnel to the serum via the drug reservoir thanks to the automatic injector; and also able to enter the serum rate foreseen for the same serum and its drug ingredient into the device as different time frames and able to provide different flow rates in the first and the second or third time frames according to these time frames entered; and enables all devices to be controlled from a single screen; and enables changes to be made in the time frames; and allows remote access.

PREVIOUS TECHNIQUE

The dose adjustment of the serums attached to the patients, receiving health services from health institutions, on a hourly basis according to the effect on the patient and the urgent stopping of the serum according to the effect it has on the patient's vitals create a problem for the healthcare personnel. The healthcare personnel should sit up with the patient and monitor them according to the instructions of the physician, and turn off the serum according to the vital signs received from the monitor. Likewise, it is necessary to adjust the run of the serum and the drug ingredients in the form of minutes/hours according to the prescription specified by the physician, and to change the serum rate at the end of the period indicated by the physician. In addition, it has been observed that the effects of the serum containing high-risk drugs prescribed by the physician administered to the patient can be fatal as a result of prescription and overdose. The instant effects of the risky and high-risk drugs administered with the serum on the patient's vitals harm the patient and even cause death. For this reason, the patient's heart rate and the amount of oxygen in the blood are monitored instantly during the administration of risky and high-risk drugs to the patient. Serum should be turned off immediately in case of changes in the patient's heart rate or the amount of oxygen in the blood. During the administration of risky drugs to the patient with serum (IV = intravenous), their effect on the patient is monitored by the healthcare personnel, who provide instant health care. These follow-ups are secured with bedside monitors, whenever possible. However, bedside monitors being very expensive, not being available in every healthcare facility or being available in inadequate numbers, make it a little difficult to follow up the patient. In addition, most of these type of materials used in health sector are imported from abroad. Biomedical devices come to our country at very high prices and are marketed to users at high costs. This situation also increases health expenditures. Lack of sufficient number of health personnel in health institutions and organizations is also considered as an additional problem. Reducing the workload of healthcare professionals and they are being obliged to serve not one but many patients make the follow-up even more difficult. DETAILED DESCRIPTION OF THE INVENTION

Our invention measures the pulse, the amount of oxygen in the blood, heart rhythm and blood pressure from among the vitals that will be taken from the patient through the sensors it incorporates by attaching to the serum set. When there is a change in these values, it turns off the serum automatically. In addition, the serum rate prescribed by the physician for the same serum and the drug ingredient can be entered into the device as different times. The flow is provided at a different speed in the first time frame and at a different speed in the second or third time frame according to these times entered into the device. For example, the treatment can be continued by entering a command to deliver serum to the patient at a different speed for the first 10 minutes and at a different rate after 10 minutes. The values taken from the patient are also transferred to the software. Thanks to the software, the dose administered to the patient is controlled. The physician puts the medication he deems appropriate into a sterile disposable reservoir. The necessary drug is added to the serum by the physician or healthcare personnel by controlling the screen or added automatically according to the findings obtained from the patient thanks to the software on the device. Dose adjustment of the added drug can be made both manually by the healthcare personnel and automatically by the device software.

Again, thanks to the software, data received from the patient, warnings about the amount and interval of the dose given to the patient can be followed from a mobile phone, tablet or smart watch. Dose adjustment, phase addition or removal, turning the serum off and on can also be done with the software. Thanks to the software, the serum of all hospitalized patients can be monitored on a single screen, and the dose given to the patient and the patient's vitals (pulse and amount of oxygen in the blood) received from the sensors attached to the device can be kept under control. In this way, serum monitoring of the patients can be done on the same screen and it can be checked whether the serum is depleted or not. The screen also conveys the amount of medication administered to the patient, total drug administration time, flow rate and warnings in case of unexpected situations. Our invention eliminates the problem of patient vitals and serum time / speed that healthcare personnel providing healthcare services cannot follow or have difficulty in following. Our invention, which is designed as an apparatus to be attached to the serum, can adjust the drug administered to the patient in 2 or more phases as time/speed. For example, if the physician prescribes that the serum and its ingredient be administered to the patient as 50 ml per minute in the first 10 minutes, and as 30 ml after 10 minutes, it will be ensured that the serum is administered as 50 ml in the first 10 minutes and as 30 ml after 10 minutes by entering this data into the device through the screen and buttons.

The apparatus subject to our invention, which is attached externally to all serum sets, able to move the circular form structure with a motor to perform at least one of the below mentioned "serum flow adjustment methods":

- in order to compress or release the serum tube,

- adjust the serum flow by pressurizing the tube back and forth with push and pull action, - pump air into ballooning system and compress the tubing by inflating the balloon.

The serum rate is also monitored on the screen and the serum phase change is reported with an audible alarm. If desired, the number of phases can be increased further. Serum rate plays an important role, especially in infants. In manual dosiflow meters, this serum flow rate cannot be fully adjusted and monitored. In our invention, while the serum is administered to the patient with the desired and precisely adjusted dosage, the pulse of the patient and the amount of oxygen in the blood are obtained instantly and a comparison is made with the values of an ordinary person. In case of any change (bradycardia-tachycardia, hypoxia-hyperoxia, hypertension, hypotension), the serum is automatically turned off and an audible alarm is given thanks to the software in the device.

The audible alarm is given both through the device or through the pager or mobile devices of the healthcare personnel.

Our invention can be applied to all serum apparatus. It is an innovative and patentable biomedical device since there is no such product on the market. The closest product to our invention is the automatic injector used in radiography, and its task is to provide the patient with a fixed speed radio opaque material at the same time as the exposure. The shortcomings of the automatic injectors currently available in the market are their inability to receive the findings of the patient, not having the software to proceed according to these findings, and administering the medicine only at a constant speed in a single phase, being very expensive, inability to apply them to serums and having a different area of use.

Manual dosiflow meters currently used in serums are devices with plastic parts having a single-phase setting, whose only task is to ensure that the serum flows according to the specified speed.

Our invention includes the screen, the input buttons that allow the user to enter the amount of drug to be administered, drug administration times, phase details and a wireless communication module for communication. The wireless communication module establishes a connection between the healthcare personnel and the patient and provides data flow.
