Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a disposable infusion set with a medicine adding pot. Background Art

[0002] An infusion set is a common medical device product that has been sterilized and is used to establish a channel between the vein and the drug solution for intravenous infusion. An infusion set is a device commonly used in the medical field to give patients infusions. It helps patients recover their health by safely and accurately delivering drugs or solutions into the patient's body.

[0003] An infusion set generally consists of a bottle stopper piercer, a bottle stopper piercer protective cover, an air inlet with an air filter and a plug, a liquid passage, a dropper, a drip bucket, a drug filter, a pipeline, a flow regulator, an injection piece, an external conical joint and an external conical joint protective cover. During general anesthesia surgery, a syringe is required to add anesthetics and other different types of drugs into the infusion set to ensure the safety of the operation.

[0004] The traditional filling method generally involves piercing the rubber seal with the needle of the syringe, and then pushing the anesthetic into the infusion set. However, during the process of piercing the rubber seal with the needle, the needle can easily prick the hand or miss the target or fail to penetrate the seal during emergency medication, resulting in delayed medication and danger to the patient. If the existing infusion set wants to have a dosing pot function, it needs to be connected to other injection parts, such as a three-way connector or a three-way extension tube, etc., which increases the number of operation steps and the cost of the patient. Therefore, it does not meet the existing needs. We propose a disposable infusion set with a dosing pot. Summary of the invention

[0008] As an optional solution of a disposable infusion set with a medicine adding pot described in the present invention, a gripping portion is provided at one end of the safety cap, and the shape of the gripping portion is a regular octagonal prism; a sealing plug is installed on the inner wall of the safety cap, and the shape of the sealing plug is conical and matches the inner wall of the medicine adding pot.

[0009] As an optional solution of a disposable infusion set with a dosing pot described in the present invention, wherein: a stirring and mixing component is arranged in the dosing pot, the stirring and mixing component includes a square groove opened in the dosing pot, the quantitative baffle is slidably connected in the square groove, the bottom of the quantitative baffle is fixedly connected to a fixed round rod, the bottom of the quantitative baffle is fixedly connected to a reset spring, the other end of the reset spring is fixedly connected in the square groove, the square groove is designed to be an isosceles trapezoid, the square groove is narrow at the top and wide at the bottom, and the square groove is opened in a position slightly lower than the middle of the dosing pot.

[0010] As an optional solution of a disposable infusion set with a dosing pot described in the present invention, wherein: a rotating groove is provided at the bottom of the dosing pot, a rotating filter plate is rotatably connected in the rotating groove, a stirring rod is fixedly connected to the lower surface of the rotating filter plate, a driving groove and a rotating track groove are provided in the stirring rod and the rotating filter plate, the fixed round rod is slidably connected in the driving groove, a rotating slider is slidably connected in the rotating track groove, the rotating slider is fixedly connected to the side wall of the fixed round rod, the stirring rod is composed of a round rod and a plurality of arc plates, the upper layer of the rotating filter plate is a unidirectional design, the rotating filter plate is a double-layer design, the upper layer has a unidirectional structure, and the lower layer has a filtering structure.

[0011] As an optional solution of the disposable infusion set with a medicine adding bottle described in the present invention, grooves are provided on both sides of the top surface of the support plate, and the two sides of the support plate are bent around the grooves.

[0012] As an optional solution of a disposable infusion set with a medicine adding bottle described in the present invention, a connecting strip is arranged between one side of the ring and the outer wall of the safety cap, bending grooves are opened on both sides of the middle part of the connecting strip, and the connecting strip is made of rubber material.

[0013] As an optional solution of the disposable infusion set with a medicine adding bottle described in the present invention, the two ends of the straight-through tube are both stepped in shape, which is convenient for docking with an external infusion hose.

[0014] As an optional solution of the disposable infusion set with a medicine adding pot described in the present invention, a clamp is provided on the outer side wall of the pipeline, and the clamp is provided between the medicine filter and the air filter.

[0015] The present invention has the following beneficial effects: 1. The disposable infusion set with a medicine adding pot is provided with a straight-through tube, and a medicine adding pot is installed in the middle of the outer wall of the straight-through tube. A safety cap is installed on one side of the middle of the medicine adding pot, and the safety cap can be docked with the top of the medicine adding pot. When in use, the safety cap is removed from the top of the medicine adding pot, and then the end of the syringe with the needle removed is inserted into the inside of the medicine adding pot, so as to facilitate the purpose of filling the medicine into the straight-through tube. After the filling is completed, the safety cap is covered again, and the use is safer, more accurate, faster and more convenient. The design of the rotating filter plate makes the rotating filter plate have two functions of one-way flow and filtering. This design can ensure that the liquid flowing in the straight-through tube cannot flow back to the medicine adding pot, so as to facilitate the medical staff to fill the liquid medicine through the medicine adding pot. In addition, the overall design is simple and convenient for popularization and use.

[0016] 2. For the disposable infusion set with a medicine adding pot, when the medicine solution needs to be added, the user needs to press one end of the syringe against the top of the quantitative baffle, drive the quantitative baffle to slide downward, and compress the reset spring. Due to the isosceles trapezoidal design of the square groove, the space on both sides of the quantitative baffle is continuously increased during the downward sliding process. At this time, the medicine solution blocked by the quantitative baffle can slide down through the gap between the quantitative baffle and the medicine adding pot. In order to further ensure that the solution on the quantitative baffle can slide to the surroundings, the quantitative baffle is designed to be a cone with a low slope. After the filling is completed, the quantitative baffle slides upward under the action of the reset spring. At this time, the quantitative baffle re-blocks the medicine adding pot. This design can effectively prevent the added medicine solution from flowing out through the medicine adding pot.

[0017] 3. In the disposable infusion set with a medicine adding pot, the medicine liquid falling through the square groove will temporarily stay on the surface of the rotating filter plate. The filtering of the rotating filter plate can reduce the rate at which the medicine liquid enters the pipeline. Through this deceleration design, the solution in the pipeline can be effectively added per unit time, so as to provide a good effect of diluting the concentration of the medicine liquid in the subsequent stirring process. In the process of the quantitative baffle plate sliding downward, the fixed round rod fixedly connected to the bottom of the quantitative baffle plate slides downward synchronously. Since the bottom of the fixed round rod is arranged in the stirring rod, and the side wall of the fixed round rod is fixedly connected with a rotating slider, and the rotating slider is slidably connected in the rotating track groove, the fixed round rod drives the stirring rod and the rotating filter plate to rotate in the process of sliding downward. Through the rotation of the rotating filter plate and the stirring rod, the added medicine liquid can be quickly stirred and fused with the medicine liquid in the pipeline, which has the effect of reducing the concentration of the added medicine liquid, so as to ensure safety during the operation.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Example 1: This example aims to solve the problem that the injection part of the existing infusion set is designed as a rubber stopper, and the injection needle needs to be repeatedly punctured when adding medicine. If you want to realize the function of adding medicine pot, you need to connect other injection parts, such as three-way connectors or three-way extension tubes and other injection consumables, which increases the operation steps and the cost of patients. Please refer to Figures 1 to 7 A disposable infusion set with a medicine adding pot comprises a bottle stopper piercer 1, a dripping bucket 15, a pipeline 16, an air filter 14, a flow regulator 17, a straight tube 12 and a medicine liquid filter 18. The pipeline 16 connects the bottle stopper piercer 1, the dripping bucket 15, the air filter 14, the flow regulator 17, the straight tube 12 and the medicine liquid filter 18 in series in sequence. A horizontally placed support plate 2 is installed on the bottom side of the outer wall of the straight tube 12, a medicine adding pot 4 is installed in the middle of the outer wall of the straight tube 12, and a quantitative baffle 3 is arranged in the medicine adding pot 4.

[0028] By rotating the design inside the filter plate 1304 (reference Figure 8 ), so that the rotating filter plate 1304 has two functions of one-way flow and filtering. This design can ensure that the liquid flowing in the straight tube cannot flow back to the medicine adding pot (the one-way structure in the rotating filter plate 1304 is a prior art, so this solution does not describe it in detail), which makes it convenient for medical staff to add liquid medicine through the medicine adding pot 4. The design of the quantitative baffle 3 limits the volume of liquid medicine entering the pipeline 16 through the medicine adding pot 4, prevents excessive addition of anesthetics and other drugs due to mistakes, and ensures safety during the operation.

[0029] A limiting convex ring 5 is installed in the middle of the outer wall of the dosing pot 4, a rotatable sleeve ring 9 is installed between the bottom surface of the limiting convex ring 5 and the outer wall of the dosing pot 4, and a safety cap 7 adapted to the top of the dosing pot 4 is installed on one side of the sleeve ring 9.

[0030] A connecting strip 6 is provided between one side of the collar 9 and the outer wall of the safety cap 7, and bending grooves are provided on both sides of the middle part of the connecting strip 6, so that it is convenient to connect the safety cap 7 with the collar 9, and prevent the safety cap from falling off after the safety cap 7 is removed. At the same time, the collar 9 and the medicine adding pot 4 can rotate relative to each other, so that the safety cap 7 can be rotated to a suitable position during the medicine filling process to avoid interference with the filling of the medicine, and the bending groove on the connecting strip 6 can reduce the thickness here, so that the connecting strip 6 can be bent at the bending groove to dock the safety cap 7 with the top of the medicine adding pot 4.

[0031] A gripping portion 8 is provided at one end of the safety cap 7, and the shape of the gripping portion 8 is a regular octagonal prism. A sealing plug 11 is installed on the inner wall of the safety cap 7. The shape of the sealing plug 11 is conical, which matches the inner wall of the dosing pot 4. This design facilitates the sealing plug 11 to enter the interior of the dosing pot 4 after the installation cap 7 is docked with the dosing pot 4, and seal the interior of the dosing pot 4. At the same time, the safety cap 7 cooperates with the outer wall of the dosing pot 4 to achieve the purpose of double protection. The sealing plug 11 adopts a conical structure to facilitate the sealing plug 11 to seal the top position of the dosing pot 4. At the same time, the inner wall of the dosing pot 4 is also provided with a conical structure, which makes it easy to dock and seal with the end of the syringe, and facilitate the drug administration operation into the infusion set through the dosing pot 4.

[0032] Grooves 10 are provided on both sides of the top surface of the support plate 2, and the two sides of the support plate 2 are bent around the grooves 10. In this way, when adding medicine, the user uses the index finger and thumb to bend the two sides of the support plate 2 along the grooves 10, which makes it easier for the user to hold the whole thing and accurately connect the end of the syringe with the medicine adding pot 4 to complete the filling of the medicine. At the same time, it is also easier for the thumb and index finger of the other hand to pinch the safety cap 7 and seal the top of the medicine adding pot 4, making it more convenient and faster to use, and safer and more sterile.

[0033] The two ends of the straight tube 12 are both stepped in shape, which is convenient for docking with the external infusion hose. By adopting the stepped structure, it is convenient to dock and install the infusion hose with the two ends of the straight tube 12. The stepped structure is convenient for limiting the installation position of the infusion hose. At the same time, according to relevant design requirements, the connection position should withstand a static axial tension of not less than 15N and last for 15s, while ensuring the sealing of the connection.

[0034] Example 2: This example is intended to solve the problem that the added liquid medicine may be too concentrated and needs to be mixed and diluted with the liquid medicine in the pipeline 16 to prevent the human body from absorbing the liquid medicine with too high concentration, which may lead to medical accidents. This example is an explanation based on Example 1. For details, please refer to Figures 1 to 7 A stirring and mixing component 13 is provided in the dosing pot 4, and the stirring and mixing component 13 includes a square groove 1301 opened in the dosing pot 4, a quantitative baffle 3 is slidably connected in the square groove 1301, a fixed round rod 1302 is fixedly connected to the bottom of the quantitative baffle 3, a reset spring 1309 is fixedly connected to the bottom of the quantitative baffle 3, and the other end of the reset spring 1309 is fixedly connected in the square groove 1301.

[0035] The quantitative baffle 3 slidably connected in the square groove 1301 closes the entrance of the dosing pot 4. The design of the quantitative baffle 3 blocks the tapered channel in the dosing pot 4. At this time, the liquid medicine circulating in the straight pipe 12 will not flow out through the dosing pot 4. When liquid medicine needs to be added, the liquid medicine is added into 4 through a syringe. During the filling process, the user needs to press one end of the syringe against the top of the quantitative baffle 3, drive the quantitative baffle 3 to slide downward, and compress the reset spring 1309. During the downward sliding process of the quantitative baffle 3, the space on both sides continues to increase. At this time, the liquid medicine passes through the quantitative baffle 3. The gap between the baffle 3 and the dosing pot 4 slides downward. In order to further ensure that the solution on the quantitative baffle 3 can slide around, the quantitative baffle 3 is designed to be a cone with a low slope. After the filling is completed, the quantitative baffle 3 slides upward under the action of the reset spring 1309. At this time, the quantitative baffle 3 blocks the dosing pot 4 again. This design can effectively prevent the added liquid from flowing out through the dosing pot 4. The design of the reset spring 1309 allows the quantitative baffle 3 to slide upward quickly when the limiting convex ring 5 is taken out, and blocks the dosing pot 4 to facilitate the next dosing process.

[0036] A rotating groove 1303 is provided at the bottom of the dosing pot 4, and a rotating filter plate 1304 is rotatably connected in the rotating groove 1303. A stirring rod 1305 is fixedly connected to the lower surface of the rotating filter plate 1304. A driving groove 1306 and a rotating track groove 1307 are provided in the stirring rod 1305 and the rotating filter plate 1304. A fixed round rod 1302 is slidably connected in the driving groove 1306. A rotating slider 1308 is slidably connected in the rotating track groove 1307. The rotating slider 1308 is fixedly connected to the side wall of the fixed round rod 1302.

[0037] The medicinal liquid falling through the square groove 1301 will temporarily stay on the surface of the rotating filter plate 1304. The filtering of the rotating filter plate 1304 can reduce the rate at which the medicinal liquid enters the pipeline 16. Through this deceleration design, the solution in the pipeline 16 can be effectively added per unit time, so as to provide a good effect of diluting the concentration of the medicinal liquid in the subsequent stirring process.

[0038] During the downward sliding of the quantitative baffle 3, the fixed round rod 1302 fixedly connected to the bottom of the quantitative baffle 3 slides downward synchronously. Since the bottom of the fixed round rod 1302 is set in the stirring rod 1305, and the side wall of the fixed round rod 1302 is fixedly connected with a rotating slider 1308, and the rotating slider 1308 is slidably connected in the rotating track groove 1307, the fixed round rod 1302 drives the stirring rod 1305 and the rotating filter plate 1304 to rotate during the downward sliding process. By rotating the rotating filter plate 1304 and the stirring rod 1305, the added liquid medicine can be quickly stirred and fused with the liquid medicine in the pipeline 16, thereby reducing the concentration of the added liquid medicine to ensure safety during the operation.

[0039] A clamp 19 is provided on the outer wall of the pipeline 16, and the clamp 19 is arranged between the liquid medicine filter 18 and the air filter 14. The clamp 19 is used to clamp on the surgical bed sheet or the patient's clothes to reduce the force transmitted to the needle by the shaking of the needle tube during the operation, thereby reducing the patient's discomfort.

[0040] The disposable infusion set with a medicine adding pot requires the following steps when used: 1) When in use, the two ends of the support plate 2 are bent along the groove 10 to facilitate the user to hold the straight tube 12, and then the two ends of the straight tube 12 are connected to the external infusion tube; 2) When in use, remove the safety cap 7, remove the needle of the syringe, and insert the end of the syringe into the inside of the medicine adding pot 4; 3) The user pushes the syringe to inject the medicine, and after the filling is completed, the syringe is removed; 4) Pinch the gripping portion 8 of the safety cap 7 and dock it with the top of the dosing pot 4 to seal the dosing pot 4, which is safe and sterile, thereby improving the safety of filling.

[0041] To sum up, when the user uses it, the disposable infusion set with a medicine adding pot is provided with a straight-through tube 12, and a medicine adding pot 4 is installed in the middle of its outer wall, and a safety cap 7 is installed on one side of the middle of the medicine adding pot 4, and the safety cap 7 can be connected with the top of the medicine adding pot 4, and then when in use, the safety cap 7 is removed from the top of the medicine adding pot 4, and then the needle of the syringe is removed, and the end of the syringe is inserted into the inside of the medicine adding pot 4, so as to facilitate the purpose of filling the straight-through tube 12 with medicine. After the filling is completed, the safety cap 7 is put back on, which makes it safer, more accurate, faster and more convenient to use. The overall design is simple and easy to promote and use. By providing the straight-through tube 12 and the medicine adding pot 4, it can play an anti-backflow effect, and thus it is convenient for medical staff to fill the medicine solution through the medicine adding pot 4.
