Description

Technical Field

[0001] The invention belongs to the technical field of life application and relates to a modular orderly liquid adding device. Background Art

[0002] The present invention mainly utilizes gravity and atmospheric pressure. Under the action of gravity, liquid will flow out of the tube, but if there is no air in the sealed space, the liquid will not flow down under the action of atmospheric pressure. This principle can be used to control the outflow of liquid.

[0003] In many aspects such as daily life, medicine, and aquaculture, different types of liquids often need to be used in sequence. In this case, manpower is generally used for control, which consumes too much manpower cost. The present invention can use different types of liquids in an orderly manner, saving manpower and time costs. Summary of the invention

[0008] The liquid injection port 2 is located above the liquid storage bottle body 1 and has threads and is equipped with a spiral sealing cover. The sealing cover contains a rubber ring to ensure the sealing performance of the liquid storage bottle body 1.

[0009] The connection port A3 and the connection port B4 are provided on the upper part of the liquid storage bottle body 1, have threads, and are provided with a sealing cover similar to the liquid injection port 2 to ensure the sealing of the liquid storage bottle body 1;

[0010] The lower ends of the connecting ports A3 and B4 are connected to the upper ends of the inner connecting tubes A6 and B7 respectively, wherein the lower end of the inner connecting tube A6 is close to the bottom of the liquid storage bottle, and the lower end of the inner connecting tube B7 is higher than the inner connecting tube A6.

[0011] The external connecting tube A8 is arranged on the outside of the bottom of the liquid storage bottle body 1, and is arranged close to the lower end of the internal connecting tube A6. The external connecting tube B9 is arranged close to the outer side of the internal connecting tube B7, passes through the bottom of the liquid storage bottle body 1, and includes an external tube section and an internal tube section; wherein the internal tube section extends to the top of the liquid storage bottle body 1, contacts the top wall of the liquid storage bottle body 1, and has an air vent near the top. The lower ends of the external connecting tubes A8 and B9 have a circle of protrusions, and the spiral connecting caps A10 and B11 are provided with rubber rings. On the one hand, the lower ends of the external connecting tubes A8 and B9 are respectively connected with the connecting caps A10 and B11 to achieve nested connection, and on the other hand, the connecting caps A10 and B11 are respectively connected with the upper ends of the lower injection unit connecting ports A3 and B4 to achieve nested connection; the connecting caps A10 and B11 are equipped with spiral plugs.

[0012] Further, the lower end of the inner connecting pipe B7 is 1 cm higher than the lower end of the inner connecting pipe A6.

[0013] Furthermore, the connection between the upper and lower liquid storage bottle bodies 1 includes the following two types:

[0014] Method 1: A long hook 14 is hung below the short hook 13 of the upper injection unit, and the long hook 14 hangs the bridge support pile 5 of the lower injection unit to achieve connection with the lower injection unit.

[0015] Method 2: The bridge support pile 5 of the lower injection unit is inserted into the groove 12 of the upper injection unit to achieve the connection and fixation of the upper and lower injection units.

[0016] Furthermore, the liquid storage bottle body 1 is a cylinder, and there are three bridge-type support piles 5, which are respectively located at three equal parts of the top of the liquid storage bottle body 1 and close to the edge, and the arrangement direction of the bridges in the bridge-type support piles 5 is perpendicular to the radius of the end face of the liquid storage bottle body 1.

[0017] Further, the inner connecting pipe is a straight thin pipe with a diameter slightly smaller than the connecting port. The outer pipe sections of the outer connecting pipe A8 and the outer connecting pipe B9 are divided into soft pipes.

[0018] Furthermore, the outer connecting pipe and the inner connecting pipe have the same diameter.

[0019] Furthermore, the length of the short hook 13 is shorter than the supporting pile 5 .

[0020] Furthermore, according to user needs, the flow rate or liquid output can be adjusted by setting the radius of the inner connecting pipe A6, the inner connecting pipe B7, the outer connecting pipe A8, and the outer connecting pipe B9.

[0021] Furthermore, according to the needs of users, the one-time liquid output can be controlled by setting the height difference among the inner connecting tube A6, the inner connecting tube B7, the outer connecting tube A8, and the outer connecting tube B9.

[0022] Furthermore, the bottom surface of the liquid storage bottle body 1 of each injection unit is an inclined surface with a certain slope, which reduces the mixing of different liquids and ensures that the liquid of the injection unit above will start to be injected only after the liquid of the injection unit has been completely drained.

[0023] The invention discloses an application of a modular sequential fluid adding device, which is mainly used for patient infusion.

[0024] A method for using a modular orderly liquid adding device, the steps are as follows:

[0025] (1) Liquids of different types and volumes are packaged in the liquid storage bottle main body 1 of different liquid injection units for standby use as needed; when injecting liquid into the liquid storage bottle main body 1 of each liquid injection unit, a spiral plug is used to plug the lower ports of the external connecting tube A8 and the external connecting tube B9 to prevent liquid leakage, and the sealing covers on the liquid injection port 2 and the connecting ports A3 and B4 are opened to inject liquid from the liquid injection port 2. The amount of liquid added is controlled as needed, but it is required to cover the lower port of the internal connecting tube B7; after adding the liquid, the liquid injection port 2 and the connecting ports A3 and B4 are sealed with a sealing cover.

[0026] (2) Connect all the injection units in the order of dripping, and the one that needs to be filled with liquid first is at the bottom. Between two adjacent injection units: the lower end of the external connecting tube A8 of the upper injection unit is connected to the connecting port A3 of the lower injection unit through the connecting cap A10, and the lower end of the external connecting tube B9 of the upper injection unit is connected to the connecting port B4 of the lower injection unit through the connecting cap B11; air must be prevented from entering during the connection process; when the piston of the connecting cap of the upper liquid storage bottle body 1 is opened, since the injection port 2, the connecting port A3 and the connecting port B4 of the liquid storage bottle body 1 are all sealed, no air will enter, and the liquid in the liquid storage bottle body 1 will not flow out.

[0027] (3) Place the outer connecting tube A8 of the bottom liquid storage bottle body 1 in the required position, open the piston of the connecting cap A10, and then open the liquid injection port 2, so that air enters the upper part of the liquid storage bottle body 1, and the liquid flows out along the outer connecting tube A8. Since the liquid does not pass through the lower ports of the inner connecting tubes A6 and B7, no air enters the upper liquid storage bottle body 1, and the liquid therein cannot flow down.

[0028] (4) When the liquid level of the bottom liquid storage bottle body 1 drops to the lower end of the inner connecting tube B7, air will enter from the lower end of the inner connecting tube B7, pass through the outer connecting tube B9 of the upper liquid storage bottle body 1, and enter the upper liquid storage bottle body 1 from the uppermost vent hole. At this time, the liquid in the upper liquid storage bottle body 1 flows down along the outer connecting tube A8 under the action of gravity, enters the bottom liquid storage bottle body 1, and then flows down with the liquid in the bottom liquid storage bottle body 1; after a period of time, the liquid in the bottom liquid storage bottle body 1 is replaced and will continue to flow out of the liquid in the upper liquid storage bottle body 1, and the liquid level in the bottom liquid storage bottle body 1 remains near the lower end of the inner connecting tube B7; similarly, the liquid in the upper liquid storage bottle body 1 flows down in sequence. When all the liquid has flowed out, the outer connecting tube A8 of the bottom liquid storage bottle body 1 stops flowing liquid.

[0029] Beneficial effects of the present invention:

[0030] 1) This device can automatically and orderly inject liquids of different types and volumes into the required places, eliminating the trouble of manual operation, saving time and labor costs.

[0031] 2) Bridge support piles and hooks allow the device to be assembled in two ways: hanging and supporting to cope with different usage environments.

[0032] 3) The modular liquid storage bottle allows manual control of the amount and order of liquid usage, and has a large adjustable space.

[0033] 4) The external connecting tube controls the transfer of liquid between the liquid storage bottles. The flow rate of the liquid can be controlled by adjusting the diameter of the external connecting tube, and can be adjusted according to different liquid demand rates in different situations.
