Description

Method and device for recording injection information

The present invention relates to a recording method and device that can accurately record the time and frequency of each injection of a patient, such as an insulin injection recording method and device.

In the medical process, there is often a process that requires regular injections of drugs or nutrients. For example, patients with diabetes generally need to inject 1 to 4 times a day of insulin for control. However, because many patients fail to follow the doctor’s instructions on time for injections, it will not only delay the condition, but even cause deviations in the doctor’s treatment and medication due to the patient’s misrepresentation, concealment or misreporting of the time and frequency of injections, which will not only affect When the patient's condition is controlled, the life of the patient may even be endangered in severe cases.

The patent case No. I631969 of Invention No. I631969 "Auxiliary Device Installed in Injection Device, System Containing Auxiliary Device and Injection Device, Method of Operating Auxiliary Device Installed on Injection Device, and Computer Program" announced on August 11, 107, It is disclosed that the auxiliary device includes: a display; a processor configuration; a dose counting detector, which is operable to detect a dose of a medicine flowing into an installed injection device; a dose delivery determiner, which is used to determine A drug dose that has been delivered; a quantity determiner, which is used to determine the amount of a drug that has been delivered; and a clock, which is configured to determine a current time; when the auxiliary device is in a preset mode, the The processor is configured to continuously display the number of a drug delivered from a last dose to the present, and alternately display the elapsed time from the delivery of the last dose to the present and the identification of the drug that the last dose has been delivered. The user installs the auxiliary device On the pen needle. The auxiliary device reads the injected dose, and it can also transmit it to a blood glucose monitoring system with insulin titration capability. For patients who use multiple insulins, the auxiliary device can identify the device structure and insulin type, and can also send this information to the blood glucose monitoring system. In addition, the information displayed on the display can also be converted into a sound signal through the speaker and played back to the user, such as counting the dose, recommended dose, recommended time for administration, and so on.

Although the previous patent case transmits the injected dose information to any computerized system, or generates a warning signal to remind the user to use the next dose. And the patient can also be reminded to administer the next dose after receiving the warning signal, for example, at an appropriate time after the first dose of medication has been injected. However, the auxiliary device must be additionally combined with a disposable insulin syringe to be used, so it is quite troublesome. Although the auxiliary device can be used repeatedly, it also increases the purchase cost.

The present invention is also a method for recording injection information. In the same way, insulin injection is taken as an example, combined with the above-mentioned recording device for injection information. As shown in the second and fourth figures, the present invention includes the following steps:

A. Trigger a first time signal with a needle remover, and record the time when the first time signal is triggered. As shown in the fifth picture, when the patient needs to start insulin injection, the injection needle needs to be removed With a needle cover (B1) of (B), the pressing part (141) of the pressing element (14) outside the channel (12) of the needle remover (1) can be pressed with fingers, and The finger exerts an external force to overcome an elastic force of the elastic element (15), so that the contact pressure portion (142) can compress the elastic element (15), and make the pressing element (14) in the channel (12) ), when the touch portion (142) of the pressing element (14) is in contact with the contact surface (13), the touch portion (142) will simultaneously touch the touch switch (2) The trigger terminal (21) and the touch switch (2) are triggered to generate the first time signal. The processing unit (3) receives and records the time when the first time signal is triggered. At the same time, the through hole (143) is made to exactly correspond to the unloading pin hole (11).

B. Fix an injection needle in the needle remover, thereby removing one of the needle outer caps of the injection needle. As shown in the fifth figure, insert the injection needle (B) together with the needle cover (B1) into the needle removal hole (11), and make the needle cover (B1) pass through the through hole ( 143). Then the finger is released from the pressing portion (141) of the pressing element (14), and the external force is no longer applied. By releasing the external force, the pressing element (14) uses the elastic force of the elastic element (15) to return the pressing element (14) to its original position, and at the same time, the contact pressure portion (142) is no longer connected to the The contact surface (13) is in contact, and the through hole (143) is offset and staggered with the pin unloading hole (11), so that the needle cover (B1) can be clamped and fixed (as shown in the sixth figure). Since the touch portion (142) no longer touches the trigger terminal (21) of the touch switch (2), at this time, the touch switch (2) no longer generates the first time signal. And by clamping and fixing the needle cover (B1) by the pressing element (14), the injection needle (B) can be easily pulled out to remove the needle on the injection needle (B) Cover (B1), and then use the injection needle (B) to inject insulin into the patient.

C. Trigger a second time signal with the needle remover, and record the time when the second time signal is triggered. As shown in Figure 6, after the injection needle (B) is injected, the injection needle (B) can be inserted back into the needle cover (which is still fixed on the needle remover (1)). B1), after the injection needle (B) is combined with the needle cover (B1), press the pressing part (141) of the pressing element (14) with a finger again, and apply an external force to make the touch The pressing portion (142) can compress the elastic element (15), and the pressing portion (142) simultaneously touches the trigger end (21) of the touch switch (2), and makes the touch switch ( 2) The second Time signal. The processing unit (3) receives and records the time when the second time signal is triggered. At the same time, make the through hole (143) exactly correspond to the needle discharging hole (11), instead of clamping and fixing the needle cover (B1), then the injection needle (B) and the needle cover ( B1) Take them out together for additional recycling. Then the finger is released from the pressing portion (141) to release the external force, and the pressing element (14) returns to the original position, so that the touch switch (2) no longer generates the second time signal.

D. A processing unit compares the time difference between the first time signal and the second time signal at the time of triggering with a time standard value, so as to determine whether the second time signal successively becomes an injection message. The processing unit (3) compares the time standard value with a time difference between the time of the first time signal at the time of triggering and the time of the second time signal at the time of triggering. The time standard value is entered in advance. It is based on the fact that ordinary people press the pressing element (14) to generate the first time signal, and then separate the injection needle (B) and the needle cover (B1) for injection After finishing the insulin, insert the injection needle (B) back to combine with the needle cover (B1), press the pressing element (14) a second time to generate the second time signal, and pull it out The time required for the injection needle (B) until the pressing element (14) is finally released is the time standard value. If after comparison, the time difference is lower than the time standard value, it will be regarded as unqualified insulin injection times, which may be triggered by mistake, so the processing unit (3) will eliminate it. Also, if after comparison, the time difference is within the range of the time standard value, the processing unit (3) will judge the number of insulin injections as qualified, and record it as a qualified number of injections, and record the first The time of a time signal at the time of triggering and the time of the second time signal at the time of triggering become the injection information, and the injection information is stored in the memory unit (4). If the time difference is higher than the time standard value, it will also be recorded as the number of qualified injections and become the injection information. However, the medical staff will read the injection information afterwards and will specifically target the injection information. Ask the patient the reason for the longer time at the time of the injection of the injection message, as a reference for medical diagnosis.

E. Output the injection information for reference for medical diagnosis. After repeating the above steps A to D several times, a certain amount of the injection information can be accumulated and recorded. Then, the sending unit (5) can periodically output the injection message to an electronic device (A) of the remote medical unit for reference by medical staff for medical diagnosis. When the patient sees a doctor, the medical staff can directly read the injection information through the screen (73), which can also be used as a reference for medical diagnosis.

F. The processing unit periodically sends out an injection reminder signal according to an injection time. The processing unit (3) can periodically send an injection reminder signal to the warning unit (6) according to a preset injection time. After the warning unit (6) receives the injection reminder signal regularly, it controls the warning lamp (61) to display a warning flash (as shown in the first figure), and the buzzer (62) to play a warning sound, In order to remind patients to inject insulin regularly to avoid missing the injection time and affecting their condition.

In this way, the above-mentioned injection information recording method is used to accurately and fully record the time and frequency of each injection by the patient, so as to prevent the patient from misrepresenting, concealing or falsely reporting the injection time and frequency, which can be a correct reference for doctors in diagnosis and treatment and medication. Help the patient's condition control. It can also remind the patient to pay attention to the injection time regularly to prevent the patient from forgetting the injection and to ensure the effective control of their condition.

The needle remover A processing unit receives and records the time when the first time signal is triggered, and makes a through hole of the pressing element correspond to a pin hole; Insert an injection needle with the same needle outer cover into the needle discharging hole, and make the needle outer cover pass through the through hole to release the external force, and the pressing element returns to the original position to make the through hole and the needle discharging hole deviate Move it staggered to clamp and fix the outer cover of the needle so that the injection needle is separated from the outer cover of the needle for injection; after the injection of the injection needle is completed, the injection needle is inserted back into the outer cover of the needle, The injection needle is combined with the needle cover, and then the external force is applied to the pressing element to displace the pressing element and trigger the touch switch to generate a second time signal. The processing unit receives and records the The time when the second time signal is triggered, and the through hole corresponds to the needle removal hole, and the needle cover is no longer clamped and fixed so that the injection needle and the needle cover can be taken out together. The needle cover is inserted into the pin-unloading hole to trigger a photoelectric switch at the same time. After the photoelectric switch is triggered, the touch switch is controlled to start generating the first time signal and the second time signal; the processing unit is based on the A time difference between the first time signal and the second time signal at the trigger time is compared with a time standard value, and the time difference is within the range of the time standard value, and the processing unit records it It is the number of qualified injections, and records the time when the first time signal and the second time signal are triggered to become an injection message, and the injection message is stored in a memory unit. For example, the injection message recording method of claim 13, wherein the injection message is periodically output to a remote electronic device through a sending unit in the needle removal base. For example, the method for recording injection information in claim 13, wherein the injection information is directly read through a screen on the needle removal base. For example, the injection message recording method of claim 13, wherein a scheduled injection time is input to the processing unit in advance, and the processing unit periodically sends out an injection reminder signal to a warning unit of the needle discharge base, and the warning unit Then control a warning light to display a warning flash, and control a buzzer to play a warning sound.
