Description

A drip chamber with a regulator integrated with a locking device and an infusion set including the same

[0001] The present invention relates to a regulator-integrated drip chamber having a locking device and an infusion set including the same.

[0002] An IV set is a type of medical device used to inject intravenous fluids into the body for medical purposes. A typical IV set comprises an IV bag, a drip chamber for draining the fluid from the IV bag, a supply hose (tube) connected to the drip chamber, a fluid regulator for controlling the amount of fluid passing through the supply tube, and a catheter inserted into the patient's blood vessel.

[0003] Figure 1 is a schematic diagram of a typical sap set.

[0004] And the drip chamber includes a body part that stores a certain amount of fluid, an inlet port for introducing fluid into the drip chamber through a spike inserted into the fluid bag, and an outlet port for discharging the fluid stored in the drip chamber through a supply hose.

[0005] When administering fluid to a patient using a conventional IV set as described above, once all the fluid has been administered to the patient, the IV bag must be replaced immediately, or the IV administration must be terminated and the catheter must be removed from the patient's blood vessel.

[0006] If the IV set is left to run out of fluid, a dangerous situation may occur where air flows into the patient's blood vessels through the supply tube, or blood flows back through the supply tube due to pressure differences.

[0007] Therefore, conventional IV sets had the inconvenience of requiring doctors, nurses, or guardians to frequently check the remaining amount of IV fluid stored in the IV bag or drip chamber.

[0008] In order to solve these problems, domestic patent registration No. 10-1027081 (March 29, 2011) and others introduce a blood backflow prevention device configured to place a buoyancy ball having a weight and size that can float on the fluid inside the drip chamber of the IV set, and when all the fluid inside the drip chamber is drained, the buoyancy ball descends to block the fluid discharge port.

[0009] In addition, Patent No. 10-0792805 (January 2, 2008) introduces a wireless liquid level detection device including a magnetic float that floats according to the level of the liquid filled in the drip chamber of the IV set, at least two magnetic proximity switches that are installed at a certain interval outside the drip and output an on / off signal according to the position of the float, and an interface connector that electrically connects the signal output terminal of the magnetic proximity switches to an emergency call system or alarm unit installed in the hospital.

[0010] However, the floating member of this conventional technology has a structure that makes it difficult to accurately close the discharge hole of the drip chamber because it floats on the sap level.

[0011] These prior technologies only allow for the determination of when the intravenous fluid supply from the intravenous bag is complete, but do not mention the means or tasks for accurately supplying the intravenous fluid to the patient in the amount set by the intravenous bag.

[0012] Accordingly, the present invention has been devised to solve the above-described conventional problems, and according to an embodiment of the present invention, a regulator for controlling the amount of fluid supplied is provided integrally with the drip chamber rather than on one side of the supply hose, thereby enabling a more compact fluid chamber to be constructed, and the purpose is to provide a regulator-integrated drip chamber with a locking device and an infusion set including the same, which can achieve convenience in assembling and arranging the infusion set.

[0013] According to an embodiment of the present invention, the purpose is to provide a regulator-integrated drip chamber with a locking device and an infusion set including the same, which can prevent the risk of the regulator being malfunctioning by a patient, a guardian, or another person during infusion by providing a locking device to the regulator.

[0052] Below, the configuration and function of a regulator-integrated drip chamber according to an embodiment of the present invention will be described.

[0053] First, Fig. 2 illustrates a front view (chamber cover type) of a regulator-integrated drip chamber according to an embodiment of the present invention. And Fig. 3 illustrates a front view (spike type) of a regulator-integrated drip chamber according to an embodiment of the present invention.

[0054] According to an embodiment of the present invention, the drip chamber is connected to an IV bag to supply the IV fluid from the IV bag, and as shown in FIG. 3, it can be seen that it can be configured in a spike type having a IV hole (22), an air hole (23), an air filter (24), and a vent cap (25), and as shown in FIG. 2, in a cover type having a chamber cover (11) and a connection connector (12) connected to the IV bag. Hereinafter, the cover type will be described as an example. However, the scope of the rights is not limited to this type.

[0055] The body (10) of the drip chamber (100) is connected to a fluid bag (1) so that the fluid stored in the fluid bag is supplied internally in the form of droplets, and has a lower part provided with a discharge hole and to which a supply hose (2) is connected.

[0056] And, the drip chamber (100) according to the embodiment of the present invention is characterized by including a regulator (50) that is integrally connected to one side of the lower part of the body part (10) and controls the flow rate of the liquid supplied from the body part (10) to the supply hose (2).

[0057] In addition, the drip chamber (100) according to the embodiment of the present invention is provided with a filter member on one side of the lower inner portion of the body part (10) to filter out foreign substances, etc., and this filter member (40) may be configured to be made of a hydrophilic membrane to prevent gas (air) from flowing into the supply hose.

[0058] A regulator (50) according to an embodiment of the present invention may be configured to include an upper body part (51) and a lower body part (55) that can rotate around the upper body part (51).

[0059] The upper body part (51) is integrally connected to one side of the lower body part (10) of the drip chamber (100), and has an exhaust hole (52) formed on one side of the lower surface, and a central rotation axis (53) protruding downward from the center of the lower surface. In addition, a filter member (40) is installed inside the upper body part to prevent foreign substances and air injection for the safety of the patient.

[0060] In addition, the lower body part (55) is provided with a rotation shaft introduction groove (57) into which a central rotation shaft (53) is inserted, and a supply hole (56) formed on one side of the upper surface. Accordingly, the amount of sap supplied can be controlled as the lower body part (55) rotates about the central rotation shaft (53).

[0061] In addition, an insertion groove is formed on the outer surface of one side of the lower portion of the rotation center axis (53) of the upper body part (51), and a catch (58) is formed on the outer surface of the lower portion of the lower protrusion tube to form a rotation axis introduction groove of the lower body part (55). Accordingly, the lower protrusion tube connected to the lower body part (55) can serve as a locking device to prevent separation of the upper body part (51) and the lower body part (55) by holding the center of the rotation center axis (53) of the upper body part (51).

[0062] And, a gasket (59) made of silicone is placed in the space between the contact surfaces of the upper body part (51) and the lower body part (55), so that the upper body part (51) and the lower body part (55) can rotate smoothly around the central axis and prevent leakage.

[0063]

[0064] And as will be described in detail later, the regulator (50) according to an embodiment of the present invention may be configured to include a locking device (60) that limits the rotation of the lower body portion (55).

[0065] Fig. 4 illustrates a front view (chamber cover type) of a regulator-integrated drip chamber having a flow rate measuring unit according to an embodiment of the present invention. Figs. 5 and 6 illustrate front views (chamber cover type) of a regulator-integrated drip chamber having a flow rate measuring unit and a floating member according to an embodiment of the present invention.

[0066] The drip chamber (100) according to an embodiment of the present invention may be configured to include a flow rate measuring unit (30) installed on one side of the body part (10) to detect droplets of fluid passing through the body part (10) and measure the amount of fluid supplied.

[0067] In addition, the floating member (70) floats on the sap stored in the body (10) and is configured to close the discharge hole (62) when the sap supply to the supply hose (2) is completed.

[0068] The flow rate measuring unit (30) according to an embodiment of the present invention may be composed of a light sensor, an infrared sensor, a laser sensor, etc., and may be composed of a light emitting unit (31) that irradiates light, etc., and a light receiving unit (32) that receives reflected light. Falling sap droplets are detected through this sensor, and the supply flow rate calculation unit (33) receives this measurement value and calculates the supply flow rate and the total amount supplied based on the cycle of the sap droplets or the number of sap droplets supplied during a specific cycle.

[0069] FIG. 7 is a front view (chamber cover type) of a regulator-integrated drip chamber having a flow rate measuring unit, a water level sensor, and a floating member according to an embodiment of the present invention.

[0070] In addition, as illustrated in FIG. 7, the drip chamber (100) according to the embodiment of the present invention may further include a water level sensor (90) that measures the liquid level within the drip chamber.

[0071] At this time, the floating member (70) can perform the function of a reflector. Therefore, the water level sensor can be configured to measure the water level within the drip chamber (100) based on the position of the floating member (70).

[0072] And it can be configured to send out notification data when the water level falls below a set range.

[0073] In addition, as described later, the management server (110) may be configured to include a residual fluid calculation unit (91) that calculates the amount of residual fluid up to the tip of the drip chamber (100), supply hose (2), and catheter (3) according to the water level of the drip chamber (100).

[0074] Accordingly, the control unit (120) controls the flow rate control unit (80) to stop the fluid supply when the value obtained by subtracting the residual fluid amount calculated in the residual fluid calculation unit (91) from the total supply amount calculated in the supply flow rate calculation unit (33) reaches the set supply amount.

[0075] That is, information about the length and inner diameter of the supply hose (2), the amount of remaining fluid according to the size of the supply hose, etc. are input, and if the water level value in the drip chamber (100) is known from the water level sensor (90), the flow rate of the fluid remaining in the drip chamber from the catheter can be calculated in real time.

[0076] By subtracting this remaining amount of fluid from the total amount of fluid supplied from the infusion bag (1) to the drip chamber (100), the amount of fluid actually supplied to the patient can be calculated, and the control unit (120) controls the fluid supply to be stopped through the flow control unit (80) when the supply amount set based on the amount of fluid actually supplied to the patient reaches the amount of fluid actually supplied to the patient.

[0077]

[0078] Fig. 8 is a cross-sectional view of a regulator-integrated drip chamber having a locking device according to a first embodiment of the present invention. Fig. 9 is a cross-sectional view of Fig. 9 with the lower body portion removed. Fig. 10 is an enlarged view of the locking device portion of Fig. 8.

[0079] And Fig. 11 illustrates a cross-sectional view of a locking device body, a cross-sectional view of a locking member central member, a cross-sectional view of a locking member lever, and a plan view according to a first embodiment of the present invention.

[0080] Also, FIG. 12 is a cross-sectional view of a locking device in unlock mode according to a first embodiment of the present invention, and FIG. 13 is a cross-sectional view of a locking device in lock mode according to an embodiment of the present invention.

[0081] As shown in FIGS. 8, 9 and 10, 11, 12 and 13, it can be seen that the regulator (50) can be configured to include a locking device (60) that limits the rotation of the lower body part (55).

[0082] A locking device according to a first embodiment of the present invention may be configured to include a locking device body (61) having an internal screw thread (63), and a central member (64) connected to a lever and having a catch (65) screw-connected to the internal screw thread (63).

[0083] First, an insertion groove (54) is formed at the bottom of the central rotation axis (53) of the upper body (51) of the regulator (50).

[0084] The locking device body (61) is placed between the central rotation axis (53) and the rotation axis introduction groove (57), and has a lower hole (62) and an internal screw thread (63) formed on the inner surface.

[0085] The central member (64) is mounted in the lower hole (62) and is configured to have a catch (65) in which the screw thread (66) on the outer surface is screw-connected with the internal screw thread (63). In addition, it includes a lever (67) for rotating the central member.

[0086] Therefore, in the release mode, as shown in Fig. 12, the upper end of the central member (64) is spaced apart from the upper surface of the insertion groove (54) of the central rotation axis (53), so that the lower body part (55) can rotate without restriction.

[0087] In lock mode, when the lever is operated and rotated, as shown in Fig. 13, it can be seen that the central member (64) is rotated by the screw and moves upward. Accordingly, the upper part of the central member (64) is forcibly fitted into the insertion groove (54), thereby restricting the rotation of the lower body part (55).

[0088] Below, the configuration and function of the regulator and locking device according to the second embodiment of the present invention will be described.

[0089] Figures 14 and 15 illustrate a perspective view and a front view of a regulator according to a second embodiment of the present invention.

[0090] A regulator according to a second embodiment of the present invention has a form in which an upper body part (51) and a lower body part (55) are combined, as in the first embodiment, and a gasket (59) is placed between the upper body part (51) and the lower body part (55) and is combined.

[0091] Figures 20 and 21 illustrate a perspective view and a front view of the upper body portion of a regulator according to a second embodiment of the present invention.

[0092] Figures 22 and 23 illustrate a perspective view and a plan view of a gasket of a regulator according to a second embodiment of the present invention.

[0093] Figures 24 and 25 illustrate a perspective view, a front view, and a bottom view of the lower body portion of a regulator according to a second embodiment of the present invention.

[0094] Figures 27 and 28 illustrate a perspective view and a plan view of a locking device according to a second embodiment of the present invention.

[0095] As shown in FIGS. 20 and 21, a discharge hole (52) is formed in the upper body part (51), and a central rotation axis (53) protruding toward the lower side of the lower surface is connected.

[0096] And, screw threads are formed on the lower outer surface of this central rotation axis (53). As will be described later, the screw threads of this central rotation axis (53) are screw-connected with the internal screw threads (63) of the locking device (60).

[0097] And the lower body part (55) is joined with the upper body part (51) in a state where the gasket shown in FIGS. 22 and 23 is placed between them, as shown in FIGS. 24 to 26. As will be described later, the lower body part (55) can rotate in the release mode to adjust the opening / closing and opening ratio of the discharge hole (52), and the rotation is restricted in the lock mode.

[0098] A supply hole (56) is formed in the lower body part (55), and a rotation shaft introduction groove (57) is provided in the center through which the central rotation shaft (53) of the upper body part (51) passes.

[0099] When assembling the upper body (51) and the lower body (55), the central rotation shaft (53) passes through the rotation shaft introduction groove (57), and in the assembled state, the screw thread of the rotation shaft introduction groove (57) is directed downward. Then, the locking device described later is screwed into this screw thread.

[0100] In addition, a plurality of vertical cut portions (7) spaced apart from each other in the circumferential direction are formed in this rotational shaft introduction groove (57). Therefore, as will be described later, when the locking device is moved upward by screw rotation in the locking mode, the separation space between the cut portions is reduced, and the rotational shaft introduction groove (57) is compressed, thereby restricting the rotation of the lower body portion (55).

[0101] More specifically, FIG. 29 illustrates a partial cross-sectional view of the locking device side in the unlocking mode according to the second embodiment of the present invention, and FIG. 30 illustrates a partial cross-sectional view of the locking device side in the locking mode according to the second embodiment of the present invention.

[0102] As shown in FIGS. 29 and 30, when the upper body part (51) and the lower body part (52) are assembled, the rotation center shaft (51) with the screw threads formed penetrates the rotation shaft introduction groove (57), and in the penetrated state, the screw threads are exposed at the bottom, and it can be seen that the internal screw threads (63) of the locking device (60) are screw-connected to these exposed screw threads.

[0103] As shown in Fig. 29 in the release mode, the engaging jaw (58) of the rotation shaft introduction groove (57) and the rotation center axis (51) are spaced apart from each other, so that the lower body part (55) is not restrained and can rotate around the rotation center axis (51).

[0104] And in the lock mode, as shown in FIG. 30, when the user or the electronic device turns the rotating part (67) of the locking device (60) to move the locking device upward, the upper part of the locking device (60) comes into contact with the catch (58) of the rotation shaft introduction groove (57), and when it is further rotated, the rotation shaft introduction groove (57) is pressed and compressed to be forcibly connected to the rotation center shaft. That is, as mentioned above, a plurality of cut portions (7) are formed in the rotation shaft introduction groove (57), and when compressed by the pressurization of the locking device (60), it is forcibly connected to the rotation center shaft (53), and in this state, the rotation of the lower body part (55) is restricted.

[0107] The sap set (200) according to the embodiment of the present invention may include a flow rate control unit (80) provided on one side of the supply hose (2) to control the supply flow rate.

[0108] And the management server (110) may be configured to include a supply flow rate calculation unit (33) that receives the measured values ​​from the flow rate measurement unit (30) and calculates the supply flow rate and the total amount supplied based on the cycle of the sap droplets or the number of sap drops supplied during a specific cycle. And the setting unit is configured to set the sap supply amount and the supply speed, and the control unit can control the flow rate control unit (80) based on the measured values ​​calculated by the supply flow rate calculation unit (33) and the supply speed set by the setting unit (140).

[0109] And the control unit (120) controls the flow control unit (80) to stop the sap supply when the total sap supply amount reaches the set supply amount.

[0110] In addition, as illustrated in FIG. 7, the drip chamber (100) according to the embodiment of the present invention may further include a level sensor (90) that measures the fluid level within the drip chamber. In addition, the management server (110) may include a residual fluid calculation unit (91) that calculates the amount of residual fluid up to the tip of the drip chamber (100), supply hose (2), and catheter (3) according to the fluid level of the drip chamber (100).

[0111] Accordingly, the control unit (120) controls the flow rate control unit to stop the fluid supply when the value obtained by subtracting the residual fluid amount calculated in the residual fluid calculation unit (91) from the total supply amount calculated in the supply flow rate calculation unit (33) reaches the set supply amount.

[0112] That is, information about the length and inner diameter of the supply hose (2), the amount of remaining fluid according to the size of the supply hose, etc. are input, and if the water level value in the drip chamber (100) is known from the water level sensor (90), the flow rate of the fluid remaining in the drip chamber from the catheter can be calculated in real time.

[0113] By subtracting this remaining amount of fluid from the total amount of fluid supplied from the infusion bag (1) to the drip chamber (100), the amount of fluid actually supplied to the patient can be calculated, and the control unit (120) controls the fluid supply to be stopped through the flow control unit (80) when the supply amount set based on the amount of fluid actually supplied to the patient reaches the amount of fluid actually supplied to the patient.
