And when the patient moved out of bed, the sap bag had to be suspended from the hanger. As a result, the freedom of the body is limited, which is one of the causes of suffering in various struggles.

In this situation, the dropper is free to move with the patient, and includes a pressurized bag having both ends of the net fixed thereto, and a manual air pump for sending pressurized air to the pressurized bag. A portable dropping device is proposed, in which a sap bag is pressurized by inserting a sap bag between the bag and the sheet member to pressurize the sap bag to drop the sap. It is becoming.

However, in this portable dropping device, the feeding of the pressurizing container is performed manually, which is not only cumbersome, but also greatly changes the pressure in the pressurizing bag, thereby obtaining a substantially constant sap dropping rate (= sap dropping rate). There is a flaw that could not be.

It is therefore an object of the present invention to provide an automatically controlled portable dropping device which can safely and reliably obtain a substantially constant dropping speed.

As a result of diligent research in view of the above problems, the present inventors have an air pump which automatically sends pressurized air to a pressurized bag means for maintaining a sap bag, and according to the air pressure in the pressurized bag and / or the sap dropping speed. By controlling the supply amount and / or the dropping speed of the pressurized air, the present inventors have found that a substantially constant amount of fluid can be dropped safely and securely.

Drop counters 61 are provided on both sides of the dropping tube 6.

In addition, the pressurizing bag means 1 for protecting and holding the infusion bag 3 includes an expandable pressurizing bag 11 and a sheet member whose both ends are fixed to almost both end portions 11a and 11b of the pressurizing bag 11. It consists of 12.

An air pipe 20 is connected to the pressure bag 11, and a pressure sensor 22, a safety valve 23, and an air pump 24 are provided in the air pipe 20. The outputs of the drop counter 61, the bubble sensor 7, and the pressure sensor 22 are input to the control device 30, and the clamp device 8, the safety valve 23 and the air pump 24 are control devices. Driven by the output of 30.

As shown in Fig. 2, in the unexpanded state, the width of the pressure bag 11 is slightly longer than the width of the sheet member 12, so that the fluid bag (between the pressure bag 11 and the sheet member 12) There is a gap 13 in which 3) is put. The pressurized bag 11 may be made of any material as long as it can expand, but it is preferable to form the pressurized bag 11 so as not to stretch in order to exert a great pressure on the sap bag 3 when inflated. As such a material, a plastic sheet reinforced with a woven fabric is preferable, and the pressure bag 11 can be made by heat sealing the plastic sheet in a bag shape. The sheet member 12 is firmly fixed to almost both ends 11a and 11b of the pressure bag 11, as well as the dropping liquid in the sap bag 3 put in the gap 13 is visible. It is preferable to make it into the woven fabric of transparent mesh film, etc. of a net and a snow.

The capacity of the pressurized bag 11 is set corresponding to the capacity of the infusion bag 3. Since the capacity of the usual sap bag 3 is 500 ml, 1,000 ml and 3,000 ml, it is preferable to prepare a pressurized bag 11 of a corresponding size.

The air inlet 11c is provided in the lower end of the pressurizing bag 11, The air pipe 20 is connected to the air inlet 11c in airtight state. The air pipe 20 itself may be a rubber pipe or a plastic pipe as long as it has flexibility, airtightness, and pressure resistance. An air pump 24 including a motor is attached to the tip of the air pipe 20, and a power source 26 such as a battery is connected to the air pump 24. The air pump 24 is preferably a diaphragm compressor type for small size and light weight.

The safety valve 23 is provided in the middle of the air pipe 20. The safety valve 23 itself is provided with a pressure display means, and the pressure in the system can be confirmed. It is preferable to adjust the pressure in the system by the safety valve 23 so that the maximum blood pressure of a patient may be 300 mmHg or less. The safety valve 23 is connected to the control device 30, and is open to correspond to the pressure of the pressure bag 11 and / or the drop count number of the drop counter 61. Although not shown in the figure, a switching valve may be provided in the air pipe 20 as a device for backing up the safety valve 23. As the control device 30, a commercially available microcomputer can be used.

The sap bag 3 itself may be widely used now. In the infusion tube 5 attached to the stopper 3a provided at the lower end of the infusion bag 3 in a hermetic state, a dropping container 6, a bubble sensor 7, a clamp device 8, and an infusion needle 10 are provided. It is installed. In addition, in order to prevent air bubbles from entering the fluid tube 5, an air removing means (not shown) may be attached.

As shown in Fig. 2, the fluid bag 3 is placed in the gap 13 between the press bag 11 and the sheet member 12, and the press bag 11 is inflated. (11) and the sheet member 12 are pressed substantially uniformly. By this pressing force, the dropping liquid in the infusion bag 3 is pushed out of the infusion bag 3 at a substantially constant flow rate, and is injected into the patient's body through the infusion tube 5 into the infusion needle 10.

Similar to the drop counter 61, the bubble sensor 7 itself may be a structure which consists of a light emitting part and a light receiving part, and detects the bubble which passes through it. When the bubble sensor 7 detects bubbles, a signal is sent to the control device 30, and the control device 30 sends a signal to close the clamp device 8. At the same time, a signal for stopping the air pump 24 may be sent.

The mechanical safety valve 11a has a structure which opens mechanically when the pressure in the pressure bag 11 reaches a certain level, for example, 300 mmHg (corresponding to the patient's maximum blood pressure). Therefore, the mechanical safety valve 11a may be configured to have a valve member that is subjected to a constant pressure by, for example, a spring.

(2) Control method of sap dropping speed

(A) First embodiment (pressure control of pressurized bag)

As shown in Fig. 4, the control method of this embodiment (1) obtains the pressure in the pressurizing bag 3 which gives a predetermined dropping speed of the sap as the reference pressure P ₀ in advance, and (2) the pressure sensor 22 ) Is supplied to the control device 30 of the pressure P in the pressurized bag 11, and (3) the detected pressure value P by the control device 30 and the reference pressure P ₀ are compared. When the detected pressure value P is lower than the reference pressure P ₀ , a driving signal is supplied to the air pump 24. When the detected pressure value P is higher than the reference pressure P ₀ , a stop signal is sent to the air pump 24. It is supposed to feed. Hereinafter, each process is explained in full detail.

(1) Determination of the reference pressure

The pressure in the pressure bag 11 (reference pressure P ₀ ) necessary to obtain a constant dropping speed is generally the size and shape of the pressure bag 11 and the sap bag 3, the size and elasticity of the sheet member 12, It depends on the remaining amount of the sap in the sap bag 3 and the like. The reference pressure P ₀ is therefore a unique parameter in the dropper. Therefore, the pressure at which the predetermined dropping speed of the sap can be obtained is measured in advance, and the change in pressure over time is obtained, and this is referred to as the reference pressure P ₀ . Since the obtained reference pressure P ₀ can be applied to the portable dropping apparatus of the same type, it is stored in advance in the memory of the control device 30 of each portable dropping apparatus.

(2) Pressure detection in pressurized bag

The pressure P in the pressure bag 11 is detected by the pressure sensor 22 provided in the middle of the air pipe 20. Data of the detected pressure P is input to the control device 30.

(3) Comparison between pressure P and reference pressure P ₀

The control device 30 compares the detected pressure value P with the reference pressure P ₀ . When the detected pressure value P is lower than the reference pressure P ₀ , the pressurized pressure is insufficient in the infusion bag 3, so that the driving signal is output to the air pump 24, and the pressurized air is pumped out of the air pump 24. To the school. As a result, the pressure bag 11 expands, and the pressure pressure increases with the sap bag 3. When the detected pressure value P exceeds the reference pressure P ₀ , the expansion of the pressure bag 11 becomes excessive, and the dropping speed of the sap becomes too fast. Therefore, the control apparatus 30 outputs a stop signal to the air pump 24, and stops the air pump 24. FIG.

Thus, the dropping speed of the sap is kept substantially constant by making the pressure P in the pressure bag 11 as close to the reference pressure P ₀ as possible. In addition, it is difficult to make the pressure P and the reference pressure P ₀ completely coincide practically. When the difference ΔP between P and P ₀ reaches a predetermined value, the air pump 24 may be operated or stopped. In addition, when the safety valve 23 is provided in the air pipe 20 to open the safety valve 23 when P − P ₀ ≧ ΔP, the adjustment of the pressure P in the pressure bag 11 is safer and more accurate.

In the method of controlling the flow rate of the sap by controlling the pressure P in the pressure bag 11, since the reaction is generally slow, the fluctuation range of the pressure P tends to be relatively large. However, as a result of the experiment, even if the fluctuation range of the pressure P is large, the fluctuation range of the flow volume of the sap is relatively small, and it is found that it does not matter in actual use.

(B) Second Embodiment (Control of Pressure in Pressurized Bag According to Number of Drop Counts)

As shown in Fig. 5, this type of control method (1) determines a suitable drop count number N ₀ of the sap in advance over a predetermined time T, and stores it in the memory of the control device 30, (2 ) The dropping amount of the sap over a predetermined time T is counted by the drop counter 61 provided in the dropping container 6, (3) the measured drop count number N is compared with the reference count number N ₀ , and the drop count number When N is lower than the reference count number N ₀ , the air pump is operated. Each process is explained in full detail below.

(1) Determination of the reference count number

The number of drip counts of the sap is determined in advance for the type of the sap, the size and shape of the drop container 6, the patient's condition, and the like, within a predetermined time T (for example, 30 seconds). It is stored as a reference count number N ₀ in the memory.

(2) Measurement of the drop count number of the sap

According to the drop counter 61, the dripping number of the sap is counted over the predetermined time T, and it inputs into the control apparatus 30 by the dripping count number N. FIG.

(3) Comparison of measured drop counts with reference counts

The controller compares and 30 count the number of dropping the count number N based on the input N _0, and operates the air pump when the number of dropping the count N is less than N ₀ can reference count (24). When the pressure bag 11 expands according to the operation of the air pump 24 and the pressure pressure to the sap bag 3 increases, the amount of the sap dripping increases, so that the dripping amount of the sap remains substantially constant. In practice, it is difficult to make the drop count number N and the reference count number N ₀ completely coincide with each other. Therefore, when the difference ΔN between N and N ₀ reaches a predetermined value, the operation or stop signal of the air pump 24 may be issued. . In addition, when the safety valve 23 is installed in the air pipe 20 so that the safety valve 23 is opened when N-N ₀ ≥ ΔN, the pressure P and the drop count number N in the pressure bag 11 can be adjusted more quickly. Done.

(C) Third embodiment (flow rate control of the fluid passing through the clamping device according to the drop count number)

As shown in Fig. 6, in this type of control method, (1) a suitable drop count number N ₀ of a sap is determined in advance over a predetermined time T, and stored in a memory of the control device 30, (2 ) The amount of infusion drip is counted by the drop counter 61 provided in the dropping container 6 over a predetermined time T, and (3) the measured drop count N is compared with the reference count number N ₀ , and the drop count number N When the reference count number N ₀ is more or less, the clamp device 8 is operated in a direction of decreasing or increasing the dropping speed. Each process is explained in full detail below.

(1) Determination of the reference count number and measurement of the drop count number of the sap

As in the second embodiment, the drop count number N ₀ of the sap is stored in the memory of the control device 30 over a predetermined time T, and the sap is stored within the predetermined time T measured by the drop counter 61. The drop count number N is input into the control device 30.

(2) Comparison between measured drop count and reference count

The drop count number N is compared with the reference count number N ₀ , and when the drop count number N is larger than the reference count number N ₀ , the clamp means 81 of the clamp device 8 is pressed to open the fluid tube 5. When the accuracy is small and the number is small, the clamp means 81 of the clamp device 8 is pulled to reduce the opening degree of the infusion tube 5. In this manner, the amount of the infusion is controlled by opening and closing the clamp device 8 according to the drop count number N, which has the advantage that the amount of the infusion can be controlled relatively accurately. Also in this form, when the safety valve 23 is provided in the air pipe 20 so that the safety valve 23 is opened when N − N ₀ ≧ ΔN, the pressure P in the pressure bag 11 and the drop count number N Is more secure and accurate.

(D) Other Examples

In addition to the above embodiments, by combining the pressure sensor 22, the drop counter 61, and the clamp device 8, the output of the pressure sensor 22 and / or the output of the drop counter 61 are inputted, and the air pump ( 24) and / or the method of controlling the clamp apparatus 8 is possible. In addition, by using the safety valve 23 installed in the air pipe 20, more control methods are possible. Specific examples thereof are as follows.

(Example)

Although this invention is demonstrated in detail according to the following Example, this invention is not limited to these.

Example 1

Pressure control method in pressurized bag

The pressure in the pressurizing bag means 11 was adjusted by the control method shown in FIG. 4 using the automatically controlled portable dropping device shown in FIG. The size of each member used is as follows.

Pressurized bag: 500cm 3

Pressure Sensor: Transducer Control Unit TCB-100 (Millar)

Sap set: TS-A450CK (Terumo (株) 製, 1㏄ = 15 滴)

Sap: Hartmann S 注 "小林: Kobayashi" (Kobayashi Pharmaceutical Co., Ltd. 製, 500ml)

The pressure adjustment width in the pressurized bag 11 was 50-80 mmHg, and the pressure fluctuation in the pressurized bag 11 and the fluctuation | variation of the sap dripping amount were measured. The results are shown in FIG. In addition, the time-dependent change in the amount of accumulated sap drop by this pressure control method is shown in FIG. On the other hand, Fig. 8 also shows the changes over time of the integrated sap drop in the absence of pressure control.

As shown in Fig. 7, the amount of the sap drop also varies with the pressure change in the pressure bag 11, but the fluctuation cycle is short in about 10 minutes, so the total injection time (for example, 2 hours) is in the range. In sap, the variation of sap load is not a problem. As shown in Fig. 8, in the case of pressure control, the accumulated amount of liquid sap is linearly increased with time, but in the absence of pressure control, the increase rate of the amount of accumulated sap is gradually decreased.

Comparative Example 1

The portable dropper was used as in Example 1, and the initial pressure in the pressure bag 11 was set to 170 mmHg, and the pressure and fluid drop in the pressure bag 11 were not changed over time. Aberration was measured. The results are shown in FIG.

As shown in Fig. 9, only the initial pressure lowers the dropping speed of the sap.

As described above, the automatic controlled portable dropping apparatus of the present invention, instead of hanging the dropping liquid by gravity by hanging it on a hanger, pushes the sap to a constant flow rate by adding a constant pressure to the sap bag, and the flow rate of the sap is always It is controlled substantially constant. Therefore, the patient receiving the drop can alleviate the inconvenience of moving out of bed. In addition, since the sap bag itself can be used as it is, it costs less, as well as economical because the battery can be turned off by hanging on a hanger when in bed.
