Abstract
Description
Technical Field
[0001] The utility model relates to an infusion dripping bucket, in particular to a multifunctional infusion dripping bucket. Background Art
[0002] At present, the infusion sets used in clinic need to be vented before use so that the medicine can fill the pipeline. The pipeline is equipped with a drip bucket, which also needs to be filled with about half of the liquid. Usually, the clinical operation is to press or invert the drip bucket to discharge the gas in the drip bucket and lead the liquid to fill the drip bucket. Attention should also be paid to the rising position of the drip bucket liquid level to prevent the liquid level from being too high or too low. If the liquid level is too high, it will affect the observation of the droplet status, for example, it will affect the use of the infusion monitor. If the liquid level is too low, secondary venting will be required, wasting part of the medicine liquid, and the operation is time-consuming and laborious.
[0003] The national standard for infusion sets is synchronized with international standards. It is recommended to place the drug liquid filter in the drip bucket. Currently, more and more companies are placing drug liquid filter membranes in the drip bucket. The usual practice is to place the filter membrane at the bottom of the drip bucket so that the liquid can flow through the filter membrane to achieve the effect of filtering insoluble particles. Currently, in clinical practice, filter membranes larger than 10μm are usually placed in the drip bucket of infusion sets, but microporous filter membranes with a filtration pore size of less than 5μm are not used. This is because the retention effect of microporous filter membranes with a filtration pore size of less than 5μm will increase, resulting in a decrease in the flow rate of the infusion set, which does not meet the requirements of the standard. Utility Model Content
[0004] The utility model provides a multifunctional infusion drip bucket to overcome the defect in the prior art that the drip bucket needs to be pressed or inverted to exhaust the infusion set, and the steps are complicated, which increases the workload of medical staff.

DETAILED DESCRIPTION
[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0022] Example 1
[0023] like Figures 1 to 5 As shown, a multifunctional infusion dripping funnel comprises a dripping pot 1, wherein a filter with a cap 2 is arranged inside the dripping pot 1, wherein the filter comprises a filter upper cover 3 and a filter lower shell 5 which cooperate with each other, and a filter membrane 4 is located between the two.
[0024] The multifunctional drip bucket combines the self-exhaust device with the liquid medicine filter membrane 4 through structural design, so that a drip bucket has both automatic exhaust and liquid medicine filtering functions. Microporous filtration ensures the infusion flow rate by increasing the membrane area of the filter membrane 4 below the filter pore size of 5um, so that the drip bucket has the function of microporous filtration. The automatic exhaust function is achieved by utilizing the surface tension of the liquid and the material. When the liquid medicine flows naturally into the drip bucket, when it is lower than the height of the exhaust column 3-1, due to the surface tension, the liquid will not flow out of the drip bucket from the strip hole 3-2 of the exhaust column 3-1. As the liquid level rises, the slots 2-1 are all closed. As the liquid continues to be added, the pressure in the drip bucket will increase. When it is greater than the surface tension, the liquid flows to the liquid filter through the strip hole 3-2.
[0025] The multifunctional dripping bucket is composed of parts made of medical plastic. The top of the dripping pot 1 is a liquid inlet port 1-1, which is used to connect the infusion tube to introduce the liquid medicine into the dripping pot. There is a dropper 1-2 at the top of the dripping pot 1 to control the size of the dripping droplets. The bottom of the dripping pot 1 is connected to the filter cover 3 to form a whole. There is an exhaust column 3-1 on the filter cover 3, through which the liquid medicine will flow to the liquid medicine filter membrane 4. There are multiple strip holes 3-2 on the exhaust column 3-1, and the width of the strip holes 3-2 is usually 0.4 to 0.9 mm. The liquid level in the dripping bucket rises through the surface tension, and the air is replaced through the strip holes 3-2 to achieve an automatic exhaust effect. The guide plate 3-3 cooperates with the positioning groove 2-3 on the cap 2 to achieve a guiding and positioning effect, and the slot 2-1 on the cap and the strip hole 3-2 are staggered. The cap 2 and the filter upper cover 3 are connected as a whole, usually by ultrasonic welding. The welding line A2-2 on the cap 2 is used for ultrasonic welding. The connection method is not limited to ultrasonic welding, and the connection can also be achieved by laser welding, hot melting, etc.
[0026] A filter membrane 4 is placed between the filter upper cover 3 and the filter lower shell 5. The surface area of the filter membrane 4 is relatively large, and the liquid passes through more smoothly. It can be a microporous filter membrane with a filter pore size of less than 5um, which is welded into a whole by ultrasonic welding. The welding line B5-1 on the filter lower shell 5 is designed for ultrasonic welding. The connection method is not limited to ultrasonic welding, and the connection can also be achieved by laser welding, hot melting, etc. The liquid outlet port 5-2 below the filter lower shell 5 is the liquid outlet of the multi-functional drip bucket, and the liquid outlet port 5-2 is usually connected to the infusion tube.
[0027] When in use, the liquid medicine enters through the liquid inlet port 1-1 of the multifunctional drip bucket, and is dripped in the form of droplets through the dropper 1-2. After the liquid medicine drips in, it will not fall directly on the exhaust column 3-1, but will be blocked by the cap 2 to avoid the impact of the droplet impact. The liquid medicine flows along the slot 2-1 on the cap 2 to the exhaust column 3-1. Due to the surface tension, it will not immediately flow out from the strip hole 3-2. The droplets continue to drip, and the liquid level in the drip bucket will continue to rise until all the holes on the exhaust column 3-1 are covered with liquid. The liquid can then flow out to the filter membrane 4, and all the liquid medicine is filtered for insoluble particles through the filter membrane 4. Finally, the liquid medicine flows out from the liquid outlet port 5-2 of the multifunctional drip bucket.
[0028] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
