Description

Technical Field

[0001] The present disclosure relates to a drip chamber integrated with a regulator having a locking device and an infusion set including the drip chamber. Background Art

[0002] An infusion set is a medical device for administering an intravenous fluid to a human body. A typical infusion set includes: an intravenous fluid bag; a drip chamber for discharging the intravenous fluid from the intravenous fluid bag; a supply hose (tube) connected to the drip chamber; a flow rate regulator for controlling the amount of the intravenous fluid passing through the supply tube; and a catheter inserted into a patient's blood vessel.

[0003] Figure 1 A schematic diagram of a conventional infusion set is shown.

[0004] In addition, the drip chamber includes: a body portion for holding a certain amount of the intravenous fluid; an inlet through which the intravenous fluid flows into the drip chamber via a spike inserted into the fluid bag; and an outlet for discharging the intravenous fluid stored in the drip chamber into the supply hose.

[0005] When an intravenous fluid is administered to a patient using the conventional infusion set described above, once all the intravenous fluid has been delivered to the patient, the intravenous fluid bag must be immediately replaced, or the infusion must be stopped and then the catheter must be removed from the patient's blood vessel.

[0006] This is because when the infusion set is unattended after the intravenous fluid is exhausted, air may enter the patient's blood vessel through the supply tube, or blood may flow back into the supply tube due to a pressure difference, which may cause a dangerous situation.

[0007] Therefore, in the conventional infusion set, doctors, nurses, or caregivers have the inconvenience of having to frequently check the remaining amount of the intravenous fluid stored in the fluid bag or the drip chamber.

[0008] To solve these problems, Korean Patent No. 10-1027081 (registered on March 29, 2011) discloses a blood reflux prevention device in which a buoyancy ball is provided, and the buoyancy ball is designed to have a weight and size that allow the buoyancy ball to float on the intravenous fluid in the drip chamber of the infusion set. When all the fluid in the drip chamber is drained, the buoyancy ball drops to block the discharge.

[0009] In addition, Korean Patent No. 10-792805 (registered on January 2, 2008) discloses a passive liquid level detection device including a magnetic floating body, at least two magnetic proximity switches, and an interface connector. The magnetic floating body floats according to the level of intravenous injection fluid in the drip chamber of an infusion set. The at least two magnetic proximity switches are installed at regular intervals outside the drip chamber to output on / off signals based on the position of the floating body. The interface connector electrically connects the signal output terminals of the magnetic proximity switches to an emergency call system or an alarm unit installed in a hospital.

[0010] However, the floating members according to these prior arts are buoyant on the intravenous injection fluid level, making it difficult to accurately close the discharge hole of the drip chamber.

[0011] These prior arts can only identify the completion of the supply of intravenous injection fluid from the fluid bag and do not disclose any means for accurately delivering a preset amount of intravenous injection fluid to a patient or solving the challenge of accurately delivering a preset amount of intravenous injection fluid to a patient. SUMMARY OF THE INVENTION

According to an embodiment of the present disclosure, it is an object to provide a drip chamber integrated with a regulator having a locking device and an infusion set including the drip chamber, which realizes a more compact configuration of the drip chamber by integrating a regulator for adjusting the amount of intravenous injection fluid with the drip chamber instead of positioning it on one side of the supply hose, thereby achieving convenience in assembling and positioning the infusion set.

[0014] According to an embodiment of the present disclosure, it is an object to provide a drip chamber integrated with a regulator having a locking device and an infusion set including the drip chamber, wherein the locking device is provided to the regulator to prevent the risk of regulator malfunction caused by a patient, a caregiver, or other person during the delivery of intravenous injection fluid.

[0015] Furthermore, according to an embodiment of the present disclosure, it is an object to provide a drip chamber kit integrated with a regulator having a locking device and an infusion set including the drip chamber kit, wherein a flow rate measurement part including an optical sensor is installed in the drip chamber to check the supply amount and flow rate of intravenous injection fluid and control a flow rate adjustment part, thereby supplying intravenous injection fluid in a preset amount and flow rate.

[0016] Furthermore, according to an embodiment of the present disclosure, an object is to provide a drip chamber integrated with a regulator having a locking device and an infusion set including the drip chamber. A liquid level sensor is provided to determine the remaining amount of intravenous injection fluid from the drip chamber to the catheter, so as to monitor the amount of intravenous injection fluid actually delivered to a patient based on the supply amount and the remaining amount of the intravenous injection fluid from the intravenous injection fluid bag, and control the actual infusion amount of the intravenous injection fluid to correspond to a preset supply amount.

[0017] Meanwhile, the technical objects achieved in the present invention are not limited to the above technical objects, and from the following description, other technical objects not mentioned above will be clearly understood by those of ordinary skill in the art.

[0026] Furthermore, an infusion set including a drip chamber integrated with a regulator having a locking device further includes: a liquid level sensor for measuring the liquid level of the intravenous injection fluid inside the drip chamber; and a remaining intravenous injection fluid calculation part for calculating the remaining amount of the intravenous injection fluid reaching the tip of the catheter from the drip chamber via the supply hose.

[0027] Advantageous Effects

[0028] According to an embodiment of the present disclosure, for an infusion set including a drip chamber integrated with a regulator having a locking device, a more compact drip chamber can be configured by integrating the regulator for adjusting the amount of the intravenous injection fluid with the drip chamber instead of positioning it on one side of the supply hose, thereby achieving the convenience of assembling and positioning the infusion set.

[0029] According to an embodiment of the present disclosure, for an infusion set including a drip chamber integrated with a regulator having a locking device, the locking device is provided to the regulator, thereby preventing the risk of regulator failure caused by the patient, caregiver, or others during the delivery of the intravenous injection fluid.

[0055] BEST MODE

[0056] Hereinafter, the configuration and function of a drip chamber integrated with a regulator according to an embodiment of the present disclosure will be described.

[0057] First, Figure 2 A front view of a drip chamber (lid type) integrated with a regulator according to an embodiment of the present disclosure is shown. Figure 3 A front view of a drip chamber (spike type) integrated with a regulator according to an embodiment of the present disclosure is shown.

[0058] The drip chamber according to an embodiment of the present disclosure is connected to an intravenous fluid bag to supply intravenous fluid. It can be seen that the drip chamber can be configured in a spike type having an intravenous fluid hole 22, an air hole 23, an air filter 24, and a vent cap 25, as Figure 3 shown, and a cap type having a chamber cap 11 and a connector 12 connected to the intravenous fluid bag, as Figure 2 shown. Hereinafter, the cap type will be explained. However, it should be noted that the scope of the patent is not limited to this form.

[0059] The body portion 10 of the drip chamber 100 is connected to the intravenous fluid bag to supply the intravenous fluid stored in the intravenous fluid bag in the form of droplets inside, and the body portion of the drip chamber has a lower end provided with a discharge hole and a supply hose 2 is connected to the lower end.

[0060] In addition, the drip chamber 100 according to an embodiment of the present disclosure is characterized by a regulator 50, which is integrally coupled to one side of the lower portion of the body portion 10 and regulates the flow rate of the intravenous fluid supplied from the body portion 10 to the supply hose 2.

[0061] Furthermore, a filtering member for filtering foreign substances and the like is provided on one side of the lower inner portion of the body portion 10 of the drip chamber 100 according to an embodiment of the present disclosure. The filtering member 10 may be configured with a hydrophilic membrane to prevent gas (air) from flowing into the supply hose.

[0062] The regulator 50 according to an embodiment of the present disclosure may be configured to have an upper body portion 51 and a lower body portion 55, and the lower body portion may rotate around the upper body portion 51.

[0063] The upper body portion 51 is integrally coupled to one side of the lower portion of the body portion 10, and has a discharge hole 52 formed on one side of the lower surface and a central rotation shaft 53 protruding downward from the center of the lower end surface. In addition, a filtering member 40 for preventing foreign substances and air injection is installed inside the upper body portion for the safety of the patient.

[0064] The lower body portion 55 includes a rotation shaft insertion groove 57 into which the central rotation shaft 53 is inserted and a supply hole 56 formed on one side of the upper end. Therefore, the lower body portion 55 rotates around the central rotation shaft 53 to adjust the supply amount of the intravenous fluid.

[0065] In addition, an insertion groove is formed on the outer surface of the lower portion of the central rotation shaft 53 of the upper body portion 51, and an engaging shoulder 58 forming the rotation shaft insertion groove is formed on the outer surface of the lower portion of the lower protruding pipe. Therefore, the lower protruding pipe connected to the lower body portion 55 holds the center of the central rotation shaft 53 of the upper body portion 51 and serves as a locking device mechanism for preventing separation between the upper body portion 51 and the lower body portion 55.

[0066] In addition, a silicone gasket 59 is placed in the space between the contact surfaces of the upper body part 51 and the lower body part 55, enabling the upper body part 51 and the lower body part 55 to rotate smoothly around the central axis and preventing leakage.

[0067] Furthermore, as will be described in detail later, the regulator 50 according to an embodiment of the present disclosure can be configured to include a locking device 60 that restricts the rotation of the lower body part 55.

[0068] Figure 4 A front view of a drip chamber (chamber lid type) integrated with a regulator having a flow rate measurement part according to an embodiment of the present disclosure is shown. Figure 5 and Figure 6 A front view of a drip chamber (chamber lid type) integrated with a regulator having a flow rate measurement part and a floating member according to an embodiment of the present disclosure is shown.

[0069] The drip chamber 100 according to an embodiment of the present disclosure can be configured to include a flow rate measurement part 30 mounted on one side of the body part 10, which detects intravenous injection fluid droplets passing through the body part 10 and measures the supply amount of the intravenous injection fluid.

[0070] In addition, the floating member 70 floats in the intravenous injection fluid stored in the body part 10, and when the supply of the intravenous injection fluid to the supply hose 2 is completed, the floating member closes the discharge hole 62.

[0071] The flow rate measurement part 30 according to an embodiment of the present disclosure can be configured with an optical sensor, an infrared sensor, and a laser sensor for measuring the supplied intravenous injection fluid droplets, and includes a light emitting part 31 that irradiates light and a light receiving part 32 that receives the reflected light. The flow rate measurement part 30 detects the intravenous injection fluid droplets through these sensors, receives these measurement values, and calculates the supply flow rate and the total supply amount based on the period of the intravenous injection fluid droplets or the number of intravenous injection fluid droplets supplied during a specific period.

[0072] Figure 7 A front view of a drip chamber (chamber lid type) integrated with a regulator having a flow rate measurement part, a liquid level sensor, and a floating member according to an embodiment of the present disclosure is shown.

[0073] As Figure 7 shown, the drip chamber 100 according to an embodiment of the present disclosure can be configured to further include a liquid level sensor 90 that measures the liquid level of the intravenous injection fluid inside the drip chamber.

[0074] At this time, the floating member 70 can act as a reflector. Therefore, the liquid level sensor can be configured to measure the liquid level inside the drip chamber 100 based on the position of the floating member 70.

[0075] In addition, this can be configured to send alarm data when the determined liquid level drops below a preset range.

[0076] In addition, as will be described in detail later, the management server 110 can be configured to include a remaining intravenous fluid calculation section 91 that calculates the remaining amount of intravenous fluid from the drip chamber 100 via the supply hose 2 to the tip of the catheter 3.

[0077] Therefore, when the value obtained by subtracting the remaining intravenous fluid amount calculated by the remaining intravenous fluid calculation unit 91 from the total supply amount calculated by the supply flow rate calculation unit 33 reaches a preset supply amount, the control section 120 controls the flow rate adjustment unit 80 to stop the supply of intravenous fluid.

[0078] In other words, when information about the length and inner diameter of the supply hose 2 and the remaining amount of intravenous fluid based on the size of the supply hose is input, and the liquid level in the drip chamber 100 is detected by the liquid level sensor 90, the flow rate of the remaining intravenous fluid from the catheter to the drip chamber can be calculated in real time.

[0079] The actual amount of intravenous fluid delivered to the patient can be calculated by subtracting the remaining intravenous fluid amount from the total supply flow rate from the intravenous fluid bag 1 to the drip chamber 100. Based on this calculation, when the preset supply amount reaches the actual amount of intravenous fluid delivered to the patient, the control section 120 controls to stop the supply of intravenous fluid through the flow rate control unit 80.

[0080] Figure 8 A cross-sectional view of a drip chamber integrated with a regulator having a locking device according to a first embodiment of the present disclosure is shown. Figure 9 A cross-sectional view showing a state in which the lower body portion is excluded from Figure 9 is shown. Figure 10 Shown is Figure 8 an enlarged view of the locking device portion in

[0081] Figure 11 A cross-sectional view of the body of the locking device, a cross-sectional view of the central member of the locking member, and a cross-sectional view and a plan view of the joystick of the locking member according to a first embodiment of the present disclosure are shown.

[0082] Figure 12 A cross-sectional view of the locking device in the release mode according to a first embodiment of the present disclosure is shown. Figure 13 A cross-sectional view of the locking device in the locked mode according to a first embodiment of the present disclosure is shown.

[0083] As Figure 8 , Figure 9 andFigure 10 , Figure 11 and Figure 12 as well as Figure 13 As shown, it can be seen that the regulator 50 can be configured to include a locking device 60 that restricts the rotation of the lower body portion 55.

[0084] The locking device according to the first embodiment of the present disclosure can be configured to include: a locking device body 61 having an internal thread 63; and a central member 64 that is connected to the joystick and has an engagement step portion 65 that is threadedly connected to the internal thread 63.

[0085] First, an insertion hole 54 is formed at the lower end of the central rotation axis 53 of the upper body portion 51 of the regulator 50.

[0086] The locking device body 61 is located between the central rotation axis 53 and the rotation axis insertion groove 57, and has a lower end groove 62 and an internal thread 63 formed on the inner surface.

[0087] The central member 64 is disposed in the lower end groove 62 and is configured to have a locking step portion 65 in which a thread 66 on the outer surface is threadedly connected to the internal thread 63. In addition, this includes a joystick 67 for rotating the central member.

[0088] Therefore, in the release mode, as Figure 12 shown, the upper end of the central member 64 is spaced apart from the upper surface of the insertion hole 54 of the central rotation axis 53, so that the lower body portion 55 rotates without any restraint.

[0089] In the locking mode, when the joystick is operated and rotated, as Figure 13 shown, it can be seen that the central member 64 rotates and moves upward by the thread. Therefore, the upper end of the central member 64 is forced into the insertion groove 54, thereby restricting the rotation of the lower body portion 55.

[0090] Description of the embodiment

[0091] Hereinafter, the configuration and function of the regulator and the locking device according to the second embodiment of the present disclosure will be described.

[0092] Figures 14 to 15 A perspective view and a front view of a regulator according to the second embodiment of the present disclosure are shown.

[0093] As described in the first embodiment, the regulator according to the second embodiment of the present disclosure has a configuration in which the upper body portion 51 and the lower body portion 55 are coupled. A washer 59 is located between the upper body portion 51 and the lower body portion 55.

[0094] Figure 20 and Figure 21Shows a perspective view and a front view of the upper body portion of the regulator according to the second embodiment of the present disclosure.

[0095] Figure 22 And Figure 23 Shows a perspective view and a plan view of the washer of the regulator according to the second embodiment of the present disclosure.

[0096] Figures 24 to 25 Shows a perspective view, a front view, and a bottom view of the lower body portion of the regulator according to the second embodiment of the present disclosure.

[0097] Figure 27 And Figure 28 Shows a perspective view and a front view of the locking device according to the second embodiment of the present disclosure.

[0098] As Figure 20 And Figure 21 As shown, the discharge hole 52 is formed on the upper body portion 51 and is connected to the central rotation shaft 53 that protrudes downward from the lower surface.

[0099] In addition, a thread is formed on the outer surface of the lower portion of the central rotation shaft 53. This thread of the central rotation shaft 53 is threadedly connected to the internal thread 63 of the locking device 60.

[0100] Furthermore, as Figures 24 to 26 shown, the lower body portion 55 is coupled to the upper body portion 50 by using a washer placed between the lower body portion and the upper body portion, as Figure 22 And Figure 23 shown. As will be described later, the lower body portion 55 can rotate in the release mode, allowing adjustment of the opening and closing ratio of the discharge hole 52, while restricting its rotation in the locked mode.

[0101] A supply hole 56 is formed in the lower body portion 55, and a rotation shaft insertion groove 57 is formed at the center, through which the central rotation shaft 53 of the upper body portion 51 passes.

[0102] When assembling the upper body portion 51 and the lower body portion 55, the central rotation shaft 53 passes through the rotation shaft insertion groove 57. In the assembled state, the thread of the rotation shaft insertion groove 57 protrudes downward, and the locking device to be described later is threadedly connected to this thread.

[0103] Furthermore, in this rotation shaft insertion groove 70, a plurality of cut portions 7 are circumferentially arranged and spaced apart. Therefore, as will be described later, when the locking device rotates in the locked mode in the thread direction, it moves upward, reducing the separation space of the cut portion, compressing the rotation shaft insertion groove 57, and thereby restricting the rotation of the lower body portion 55.

[0104] More specifically, Figure 29Shows a partial cross-sectional view of the locking device in the release mode according to the second embodiment of the present disclosure. Figure 30 Shows a partial cross-sectional view of the locking device in the locking mode according to the second embodiment of the present disclosure.

[0105] As Figure 29 and Figure 30 shown, it can be seen that in the assembled state of the upper body part 51 and the lower body part 52, the central rotation shaft 51 passes through the rotation shaft insertion groove 57. In this penetrating state, the thread at the lower end is exposed, and the internal thread 63 of the locking device 60 is threadedly connected to the exposed thread.

[0106] As Figure 29 shown, it can be seen that in the release mode, the engaging shoulder 58 of the rotation shaft insertion groove 57 is separated from the central rotation shaft 51, so that the lower body part 55 is not restricted and remains rotatable around the central rotation shaft 51.

[0107] In the locking mode, as Figure 30 shown, when the torsion locking part 67 of the locking device 60 is rotated by the user or the locking device is automatically moved upward, the upper end of the locking device 60 contacts the engaging shoulder 58 of the rotation shaft insertion groove 57, further enhancing the rotation. As a result, the rotation shaft insertion groove 57 is pressurized and compressed, thereby forcibly engaging with the central rotation shaft. That is, as described above, in the rotation shaft insertion groove 57, a plurality of cut portions 7 are formed, and the cut portions are compressed by the pressure of the locking device 53, thereby forcibly engaging with the central rotation shaft 53. In this state, the rotation of the lower body part 55 is restricted.

[0108] Figure 31 Shows a block diagram of an infusion set including a drip chamber integrated with a regulator according to an embodiment of the present disclosure, and Figure 32 shows a block diagram of the signal flow of the control part according to an embodiment of the present disclosure.

[0109] The infusion set 200 according to an embodiment of the present disclosure may include a flow rate adjustment unit 80, which is provided on one side of the supply hose 2 and controls the supply flow rate.

[0110] In addition, the management server 110 may be configured to include a supply flow rate calculation part 33, which receives the measured value from the flow rate measurement part 30 and calculates the supply flow rate and the total supply amount based on the period of the intravenous injection fluid droplets or the number of intravenous injection fluid droplets supplied during a specific period. The setting part is configured to set the supply amount and supply rate of the intravenous injection fluid. The control part may control the flow rate adjustment unit 80 based on the measured value from the flow rate adjustment unit 33 and the preset supply rate.

[0111] In addition, the control section 120 controls the flow rate adjustment unit 80 to stop the supply of the intravenous injection fluid when the total supply amount of the intravenous injection fluid reaches a preset supply amount.

[0112] In addition, as Figure 7 shown, the drip chamber 100 according to an embodiment of the present disclosure may further include a liquid level sensor 90 for measuring the liquid level of the intravenous injection fluid inside the drip chamber. The management server 100 may also include a remaining intravenous injection fluid calculation section 91 that calculates the remaining amount of the intravenous injection fluid from the drip chamber 100 through the supply hose 2 to the tip of the catheter 3.

[0113] Therefore, when the value obtained by subtracting the remaining amount of the intravenous injection fluid calculated by the remaining intravenous injection fluid calculation unit 91 from the total supply amount calculated by the supply flow rate calculation unit 33 reaches a preset supply amount, the control unit 120 controls the flow rate adjustment unit to stop the supply of the intravenous injection fluid.

[0114] That is, when information about the length and inner diameter of the supply hose 2 and the remaining amount of the intravenous injection fluid based on the size of the supply hose is input, and the liquid level in the drip chamber 100 is detected by the liquid level sensor 90, the flow rate of the remaining intravenous injection fluid from the catheter to the drip chamber can be calculated in real time.

[0115] The actual amount of the intravenous injection fluid delivered to the patient can be calculated by subtracting this remaining amount of the intravenous injection fluid from the total supply flow rate from the intravenous injection fluid bag 1 to the drip chamber 100. Based on this calculation, the control section 120 controls to stop the supply of the intravenous injection fluid through the flow rate control unit 80 when the preset supply amount reaches the actual amount of the intravenous injection fluid delivered to the patient.
