Description

Technical Field

[0001] This utility model relates to a safety controller for blood transfusion and infusion, and particularly to an improvement on the stop structure of the safety controller to prevent air infiltration. Background Technology

[0002] During the injection process of an IV syringe, a controller is required to regulate the injection flow rate, ensuring a stable output of the solution before it is administered through the needle. When the injection is nearly complete, to prevent air from entering the body, the controller must immediately shut off the drip, and the needle must be removed from the injection site to ensure injection safety. A commonly used IV syringe controller may include a cup-shaped float; please refer to [link to relevant documentation]. Figure 1 This is a prior creation of the creator of this case, an improved patent application for an IV drip syringe control device, CN201210027456.8. In this conventional application, the floating device 96 and the anti-blocking device 97 are placed together in the IV drip storage cup 95. The IV drip storage cup 95 has a drip outlet at the bottom, and the anti-blocking device 97 is located at the bottom of the IV drip storage cup 95, so that the anti-blocking cover at the bottom completely covers the drip outlet.

[0003] Please refer to the following: Figure 2 , Figure 3 This is another prior creation of the creator of this case, namely the Taiwan Patent Application No. TW101202867, concerning an anti-squeezing drip infusion safety control device. This conventional application comprises a floating device 81 and an anti-pressure device 82, which are disposed in a drip storage cup 83. The drip storage cup 83 has a drip outlet at its bottom. The floating device 81 is disposed on the hollow inner edge of the anti-pressure device 82, and has a float body 84, a central base 85, and a stopper 88. The stopper 88 has a stopper membrane 86 at its end, and the float body 84 has a hollow body with a skirt 841 extending outward from the end of the body. In use, when the liquid level in the drip storage cup 83 is higher than the pressure-resistant device 82, the floating device 81 floats on the liquid interface of the drip in the drip storage cup 83 by buoyancy, and the float body 84 passes through the upper end of the pressure-resistant device 84 and is then secured below the opening 821 of the pressure-resistant device 82 by the skirt part 841. When the drip in the drip storage cup 83 is about to run out, the floating device 81 uses the anti-blocking film 86 to cover the drip outlet of the drip storage cup 83 to achieve the safety effect of preventing air from entering the human body.

[0004] While conventional designs can limit the height of the floating device 81, their structural design has flaws. The skirt 841 at one end of the buoy body 84 is located within the pressure-resistant device 82, but the opening 821 of the pressure-resistant device 82 is smaller than the skirt 841, making assembly impossible. Furthermore, when the pressure-resistant device 82 is assembled at the bottom of the drip storage cup 83, it relies solely on a tight fit, which is time-consuming, laborious, and prone to detachment, necessitating improvement. Moreover, the anti-blocking membrane 86, a suspended sheet structure, floats and moves in the dripping liquid. When it is at the bottom of the drip storage cup 83, its floating state prevents a tight seal with the drip outlet, resulting in air leakage. The anti-blocking membrane disclosed in patent application CN201010258800.5 also suffers from this drawback. Utility Model Content

[0005] The main purpose of this utility model is to provide an improved infusion and blood transfusion safety control device, which uses a full-coverage anti-reverse device to cover the outlet of the drip cup of the safety controller, thereby improving the tightness and stability of the contact when stopping, and at the same time enhancing the buoyancy effect.

[0006] To achieve the aforementioned creative objectives, this utility model provides an improved infusion and blood transfusion safety control device, characterized in that it comprises a dropper cup, a float cup, and an anti-retroviral tablet, wherein:

[0007] The hollow inner edge of the drip cup can accommodate the float cup. The upper end is provided with a needle tube that can be inserted into the drip. The lower end has a protruding tube connection part, which is connected to the drip tube for conveying the drip. The tube connection part also has a liquid outlet protruding from the inner edge of the drip cup.

[0008] The inner edge of the float cup is hollow, and several wing pieces are protruding on the outer circumference. A set of holes is formed at the bottom of the lower end for the anti-reverse piece to be embedded and fixed.

[0009] The anti-reverse valve is nipple-shaped, with a hollow part formed on its lower inner edge. The height of the hollow part is greater than the height of the liquid outlet. A flat part extends from the bottom of the outer periphery. A neck and a positioning part are provided on the top. The positioning part is embedded in the sleeve hole of the float cup and then fixed.

[0010] The drip cup is composed of an upper drip cup and a lower drip cup. The upper end of the upper drip cup has a tube protruding from it, which can be fitted with a connector at one end. The other end of the connector is connected to the infusion tube of the needle. The connector and the outlet are located at the bottom of the lower drip cup.

[0011] A stop is provided between the upper edge of the lower drip cup and the inner edge of the upper drip cup. The upper end of the stop has a larger diameter and abuts against the upper edge of the lower drip cup, while the other end of the stop has a smaller diameter and is fitted inside the lower drip cup. The hollow inner edge of the stop is provided with a cross-shaped rib, which divides the hollow inner edge into several through-holes to limit the height of the floating cup.

[0012] The drip cup is a one-piece molded structure. The float cup is located inside the cup, and a cup lid is installed at the opening at the top of the drip cup. The top of the cup lid can be used to install the syringe.

[0013] The float cup is either a one-piece molded structure or a modular structure.

[0014] This invention not only enhances the buoyancy of the float cup, but also, when the check plate covers the liquid outlet, the liquid outlet is enclosed within the hollow portion, while the flat portion is flat against the bottom surface of the drip cup, thus improving the tightness and stability of the check plate in blocking the liquid outlet.

Detailed Implementation

[0027] Please see Figures 4 to 10 As shown, this utility model provides an improved infusion and blood transfusion safety control device, which comprises a dropper 1, a float cup 50, and an anti-retrograde plate 60, wherein:

[0028] The drip cup 1 is a hollow, long cylindrical structure, which can be composed of an upper drip cup 30 and a lower drip cup 40 or be a one-piece molded structure. The hollow inner edge can accommodate the float cup 50, and the upper end is equipped with a needle tube 21 inserted into the drip bag or drip bottle. The lower end has a protruding tube connection 11 that is connected to the drip tube 22 for delivering the drip, and the tube connection 11 is located on the inner edge of the drip cup 1 and has a protruding liquid outlet 12.

[0029] Please see Figures 4-6 As shown, when the drip cup 1 is a modular structure, the lower end of the upper drip cup 30 is fitted onto the outer edge of the upper end of the lower drip cup 40, and a sleeve portion 31 protrudes from the upper end of the upper drip cup 30, allowing one end of a connecting pipe 20 to be inserted and fitted. The other end of the connecting pipe 20 is connected to the infusion tube 23 of the needle tube 21, and a drug injection tube 24 protrudes from the middle section. The tube connection portion 11 and the outlet 12 are formed at the bottom of the lower drip cup 40. Furthermore, a stop member 32 can be provided between the cup rim of the upper end of the lower drip cup 40 and the inner edge of the upper drip cup 30. The upper end of the stop member 32 with a larger diameter abuts against the cup rim of the upper end of the lower drip cup 40, while the other end with a smaller diameter is fitted inside the lower drip cup 40 to limit the floating height of the float cup 50.

[0030] Secondly, such as Figures 8-9 As shown, when the drip cup 1 is integrally molded, the upper end is an open structure, and the lower end bottom is formed with the tube connection 11 and the liquid outlet 12. After the float cup 50 is placed inside the cup, a cup lid 33 is set at the upper opening. The upper center of the cup lid 33 can be used to set the needle tube 21.

[0031] The inner edge of the float cup 50 is hollow, and it can be a one-piece molded structure (such as...). Figure 4 , Figure 5 As shown), or composed of two components nested together (such as...). Figure 8 , Figure 9 As shown), a number of winglets 51 are protruding on its outer periphery, a mounting hole 52 is provided at the center of the bottom surface at the lower end, and a buoy part 53 protrudes upward at the center of the upper end, so that one end of the anti-reverse plate 60 can be embedded in the mounting hole 52.

[0032] The anti-reverse slip 60 is generally nipple-shaped, with an arc-shaped hollow portion 61 formed on its lower inner edge. The height of the hollow portion 61 is greater than the height of the liquid outlet 12. A flat portion 62 extends from the bottom of the outer periphery. A neck 63 and a positioning portion 64 are provided on the upper part. The diameter of the neck 63 is slightly smaller than that of the fitting hole 52, while the positioning portion 64 is generally triangular and has a diameter larger than that of the fitting hole 52. The anti-reverse slip 60 is made of elastic material such as silicone. The positioning portion 64 can be squeezed through the fitting hole 52 and fixed, so that the anti-reverse slip 60 is attached to the bottom of the float cup 50.

[0033] Therefore, by utilizing the structure of the hollow portion 61 of the check valve 60 being higher than the liquid outlet 12, and the design of the flat portion 62 extending from the bottom of the outer periphery, not only can the buoyancy of the float cup 50 be improved, but also, when the check valve 60 covers the liquid outlet 12, the flat portion 62 is tightly and flatly attached to the bottom surface of the drip cup 1, so that the liquid outlet 12 can be stably covered within the hollow portion 61, improving the tightness and stability of the check valve 60 in stopping the liquid outlet 12. Furthermore, the hollow and elongated buoy portion 53 can improve the stability of the float cup 50 when it floats up and down.

[0034] The float cup 50 of this invention, combined with the improved anti-reverse plate 60, is superior to the diaphragm previously developed by the inventor. The structure of the nipple-shaped hollow part 61 makes the float cup 50 float more stably.

[0035] The embodiments described above are merely illustrative of the present invention. Any modifications, alterations, and applications made by those skilled in the art without departing from the spirit of the present invention should be included within the scope of the present invention.
