Description

Technical Field

[0001] This utility model relates to the field of human life necessities, and in particular to medical auxiliary equipment, especially an arterial pressure monitoring infusion connector. Background Technology

[0002] Invasive arterial pressure monitoring involves inserting a catheter through peripheral artery puncture. A pressure sensor connected to a monitor reflects blood pressure changes during each cardiac cycle, directly displaying systolic, diastolic, and mean arterial pressure. In surgical anesthesia, critical care, and monitoring of specific types of blood pressure abnormalities, invasive arterial pressure monitoring offers advantages such as being unaffected by external factors like manual inflation or deflation, cuff tightness, etc., accurately and promptly detecting instantaneous changes in arterial blood pressure. Furthermore, it allows for arterial blood sampling for blood gas analysis, reducing the inconvenience of repeated punctures, alleviating patient discomfort, and gaining valuable time for patient resuscitation.

[0003] In invasive arterial pressure monitoring, to ensure accurate blood pressure measurement, pressurized heparinized saline solution is introduced into the detection tubing. This prevents blood clotting in the tubing while simultaneously applying higher pressure (typically 300 mmHg), facilitating the transmission of blood pressure to the pressure sensor and generating a reliable detection signal. For this purpose, a pressure bag is installed on the heparinized saline bag. The pressure bag compresses the heparinized saline bag to generate pressure. The specific procedure is as follows: heparinized saline flushing solution is filled into the interlayer of the pressure bag; the suspension rope of the infusion bag is threaded through the hanging loop of the pressure bag; then it is secured to the infusion stand; the puncture needle at one end of the infusion set is inserted into the heparinized saline bag, connecting the infusion set to the heparinized saline bag; the other end of the infusion set is connected to the pressure sensor; and the pressure bag's air bladder is inflated by squeezing the bulb to adjust the pressure.

[0004] However, this technology has the following drawbacks: after the infusion set is connected to the end of the heparin saline bag by puncturing the needle, the connection between the puncture needle and the infusion bag may fall off due to the pressure change caused by the pressure belt. Clinically, only dressings, tapes, etc. can be used to temporarily wrap and fix it to prevent slippage, but the effect is not good, the efficiency is low, and it wastes rescue time. Summary of the Invention

[0005] The purpose of this invention is to provide an arterial pressure monitoring infusion connector, which aims to solve the technical problems of needle detachment and low fixation efficiency in the prior art.

[0006] An arterial pressure monitoring infusion connector includes a first sleeve and a second sleeve, with the bottom of the first sleeve communicating with the top of the second sleeve. The first sleeve is divided into a left first sleeve and a right first sleeve, which are connected to each other by a snap-fit. The second sleeve is also divided into a left second sleeve and a right second sleeve, with the top of the side wall of the left second sleeve hinged to the bottom of the side wall of the left first sleeve, and the top of the side wall of the right second sleeve hinged to the bottom of the side wall of the right first sleeve. One or more magnetic suction devices are provided on the bottom surface of the second sleeve. The magnetic attraction device includes two magnets with opposite polarities that attract each other. The two magnets are fixed to the bottom surfaces of the left and right halves of the second sleeve, respectively. A first through hole is provided at the center of the top plate of the first sleeve, and a second through hole is provided at the center of the bottom plate of the second sleeve. The longitudinal section of the first sleeve is trapezoidal, and the diameter of the top surface of the first sleeve is larger than the diameter of the bottom surface of the first sleeve. A first partition and a second partition are horizontally spaced inside the first sleeve, and a through hole with the same diameter as the first through hole is provided at the center of both the first and second partitions. An observation window is provided on the side wall of the second sleeve.

[0007] Furthermore, two observation windows are symmetrically opened on the side wall of the second sleeve, one at the front and one at the rear.

[0008] Furthermore, both the first and second sleeves are made of metal.

[0009] Compared with existing technologies, the advantages of this invention are positive and obvious:

[0010] 1. The first sleeve of this utility model is fitted onto the opening of the infusion bag, and the second sleeve is fitted onto the drip chamber. The connection between the first sleeve and the second sleeve prevents the puncture needle of the infusion tube from slipping out of the infusion bag.

[0011] 2. The second sleeve of this utility model is divided into two halves, and the two halves are respectively connected to the first sleeve by hinges, so that the second sleeve can be opened by hinges without removing the first sleeve, which facilitates the insertion and removal of the infusion tube.

[0012] 3. The first sleeve of this utility model is first fitted onto the opening of the infusion bag before infusion. When infusion is performed, the second sleeve is opened so that the puncture needle of the infusion set can be quickly inserted into the opening of the bag for infusion. Then the second sleeve is closed to fix it, which improves efficiency and saves time.

[0013] 4. The first sleeve of this utility model is provided with a first partition and a second partition inside. The first partition and the second partition divide the interior of the first sleeve into three regions of different diameters: upper, middle and lower, to accommodate infusion bags of different sizes.

[0014] 5. An observation window is provided on the second sleeve of this utility model to facilitate observation of the infusion status in the drip chamber. Attached Figure Description

Detailed Implementation

[0023] The following embodiments will further illustrate the present invention, but are not intended to limit the present invention.

[0024] like Figures 1 to 7 As shown, this embodiment provides an arterial pressure monitoring infusion connector, including a first sleeve 1 and a second sleeve 2. The bottom of the first sleeve 1 is connected to the top of the second sleeve 2. The first sleeve 1 and the second sleeve 2 are made of metal and can be reused, but they need to be disinfected before and after use to meet medical standards. The first sleeve 1 is an inverted truncated cone, and the second sleeve 2 is a cylinder. The first sleeve 1 is fitted onto the opening of the infusion bag 9, and the second sleeve 2 is fitted onto the drip chamber 10. The drip chamber 10 is part of the infusion set, and a puncture needle is connected to the upper end of the drip chamber 10. The puncture needle is connected to the infusion bag 9 by piercing the rubber stopper at the opening of the infusion bag 9. In this embodiment, the connection between the first sleeve 1 and the second sleeve 2 restricts the relative position of the drip chamber 10 and the infusion bag 9, thereby preventing the puncture needle of the infusion tube from slipping off the rubber stopper of the infusion bag 9.

[0025] The first sleeve 1 is divided into a left half first sleeve 101 and a right half first sleeve 102. The left half first sleeve 101 and the right half first sleeve 102 are connected to each other by two pairs of snaps set near the front and rear side wall edges, thereby assembling the left half first sleeve 101 and the right half first sleeve 102 into one unit.

[0026] The second sleeve 2 is divided into a left half, the second sleeve 201, and a right half, the second sleeve 202. The top of the side wall of the left half, the second sleeve 201, is connected to the bottom of the side wall of the left half, the first sleeve 101, by a hinge 3. The top of the side wall of the right half, the second sleeve 202, is also connected to the bottom of the side wall of the right half, the first sleeve 102, by a hinge 3. This allows the left half, the second sleeve 201, and the right half, the second sleeve 202, to open like a grabber. After opening, it is convenient to quickly insert the infusion set into the infusion bag 9, and it is also convenient to quickly put the drip chamber 10 into the second sleeve 2 after insertion, thereby improving efficiency and saving rescue time.

[0027] The top plate of the first sleeve 1 has a first through hole 6 at its center, and the bottom plate of the second sleeve 2 has a second through hole 7 at its center.

[0028] The existing infusion bag 9 has a plastic nozzle fixed to its opening. A rubber stopper is installed at the bottom of the plastic nozzle, and a flange is provided on the side wall of the plastic nozzle. The puncture needle of the infusion set is inserted into the rubber stopper and communicates with the infusion bag 9. The outer end of the puncture needle is connected to a drip chamber 10. The diameter of the first through hole 6 is slightly larger than the diameter of the plastic nozzle of the infusion bag 9, but smaller than the diameter of the flange of the plastic nozzle. The first sleeve 1 is fitted outside the plastic nozzle, and the flange of the plastic nozzle is located inside the first sleeve 1. The upper edge of the flange abuts against the lower edge of the first through hole 6, and the flange cannot pass through the first through hole 6.

[0029] The second sleeve 2 is fitted outside the drip chamber 10. The second through hole 7 is slightly larger than the diameter of the infusion tube. The drip chamber 10 is confined inside the second sleeve 2. Through the connection between the second sleeve 2 and the first sleeve 1, the drip chamber 10 is prevented from moving downward, thereby preventing the puncture needle of the infusion set from coming out of the rubber stopper.

[0030] The bottom surface of the second sleeve 2 is provided with two magnetic attraction devices 5. The two magnetic attraction devices 5 are located on both sides of the second through hole 7. Each magnetic attraction device 5 includes two magnets with opposite polarities that attract each other. The two magnets are fixed to the bottom surface of the left half of the second sleeve 201 and the bottom surface of the right half of the second sleeve 202, respectively, so as to combine the left half of the second sleeve 201 and the right half of the second sleeve 202 into one unit, and at the same time facilitate the quick separation and attraction of the left half of the second sleeve 201 and the right half of the second sleeve 202.

[0031] Two observation windows 8 are symmetrically opened on the side wall of the second sleeve 2, so that the infusion situation in the drip pot 10 can be observed from both the front and back.

[0032] The longitudinal section of the first sleeve 1 is trapezoidal, and the diameter of the top surface of the first sleeve 1 is larger than the diameter of the bottom surface of the first sleeve 1. The first sleeve 1 is horizontally spaced with a first partition 103 and a second partition 104. The center of the first partition and the second partition is provided with a through hole with the same diameter as the first through hole 6. The first partition 103 and the second partition 104 divide the interior of the first sleeve 1 into three regions: upper, middle and lower. Because the first sleeve 1 is a truncated cone, the internal space is larger at the top and smaller at the bottom. Therefore, the diameters of the three regions decrease from top to bottom and are different, so as to adapt to flanges of different diameters and specifications, making the matching degree between the first sleeve 1 and the flange higher, thereby improving the applicability of the embodiment.

[0033] How to use this embodiment:

[0034] The first sleeve 1 is pre-fitted onto the opening of the infusion bag 9 for quick use during emergency treatment. Specifically, the flange of the plastic nozzle of the infusion bag 9 is positioned below the first through hole 6, and the left half of the first sleeve 101 and the right half of the first sleeve 102 are interlocked and combined into one piece, fitting over the plastic nozzle of the infusion bag 9.

[0035] During rescue, the second sleeve 2 is opened by separating the left half of the second sleeve 201 and the right half of the second sleeve 202. The puncture needle of the infusion set is inserted into the rubber stopper of the infusion bag 9. The second sleeve 2 is then closed, so that the second sleeve 2 is fitted over the drip chamber 10 of the infusion set, thereby fixing the infusion bag 9 to the infusion set and preventing the puncture needle of the infusion set from slipping out of the rubber stopper of the infusion bag 9.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
