[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. 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.
[0028] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0029] In the description of the embodiments of the present utility model, it should be noted that the terms "upper", "inner", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model.
[0030] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0031] See also Figure 1-3 The utility model provides an infusion set with safe dosing, comprising:
[0032] A drip pot 1, wherein the drip pot 1 is provided with a bottle stopper piercer 2, wherein the bottle stopper piercer 2 is provided with a medicine adding port 3, and wherein the medicine adding port 3 is provided with a sealing cover 4;
[0033] An infusion tube 5 , one end of which is connected to the drip pot 1 , a flow rate regulator 6 is provided on the infusion tube 5 , and the other end of which is connected to an injection needle 7 .
[0034] like Figure 3 , a hollow float 8 is arranged in the drip pot 1, and a plastic rod 9 is arranged below the hollow float 8, and the diameter of the thickest part of the plastic rod 9 matches the inner diameter of the infusion tube 5. When the drip pot is filled with liquid, the hollow float floats up and the liquid medicine enters the human body through the dropper at the bottom of the drip pot. When the liquid medicine in the drip pot decreases, the hollow float connected with the plastic rod also drops. When the thickest part of the plastic rod is in close contact with the dropper at the bottom of the drip pot of the infusion device, the liquid medicine can be stopped from continuing to be injected into the human body. The doctor can remove the needle or replace a new infusion bottle at this time. The hollow float is a hollow magnetized steel ball float. After replacing a new infusion bottle, the medical staff can use a magnet to attract the hollow magnetized steel ball float inside it to move upward and at the same time make the liquid medicine in the new infusion bottle fill into the drip pot so that the hollow magnetized steel ball float connected with the plastic rod floats up, and the liquid medicine can continue to enter the human body.
[0035] The plastic rod 9 is provided with a connecting line, which is connected to the infusion tube 5. This makes it easy for the plastic rod to enter and exit the infusion tube.
[0036] Two Luer connectors 10 are arranged on the infusion tube 5, and the flow rate regulator 6 is located between the two Luer connectors 10. When the drip pot is blocked, the drip pot can be easily replaced.
[0037] The infusion tube 5 is provided with an air collecting pot 11, and the air collecting pot 11 is located at one end of the infusion tube 5 close to the injection needle. The air in the medicine liquid can be further discharged. A medicine filter is provided between the injection needle and the air collecting pot, and the medicine liquid can be filtered.
[0038] The gas collecting pot 11 is provided with at least one exhaust pipe 12, which is convenient for exhausting gas and can also be used as a dosing port. An openable cover is provided on the exhaust pipe.
[0039] Working principle: By setting a dosing port on the bottle stopper puncture device and a sealing cover on the dosing port, dust is avoided on the dosing port, and the aseptic conditions are better, which can reduce the incidence of hospital infection and help patients recover. Due to the presence of the drip pot, air is prevented from entering the patient's body, reducing the risk of air embolism. Since the dosing port is a certain distance away from the patient's venous puncture point, the intravenous injection will not increase the patient's pain due to the operation of medical staff.
[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
