Description

Technical Field

[0001] The utility model relates to the technical field of infusion sets, in particular to the technical field of intravenous infusion components. Background Art

[0002] Intravenous infusion is a treatment method that uses the principles of atmospheric pressure and liquid static pressure to introduce large amounts of sterile liquids, electrolytes, drugs or blood into the body through the veins. It can be divided into peripheral intravenous infusion, central venous infusion, hypernutrient infusion (TPN) and blood transfusion according to the injection site and the substance delivered. Intravenous infusion can easily and quickly make the drug reach an effective concentration (and can maintain the constant concentration required for the drug's efficacy for a certain period of time). It can replace subcutaneous or intramuscular injection to avoid drug stimulation to the muscles or subcutaneous tissues, and can also quickly replenish the body's lost fluids or blood (for patients who cannot use enteral nutrition normally, parenteral nutrition support therapy can be performed through intravenous infusion of nutrient solution).

[0003] An intravenous infusion set is a common medical consumable for intravenous injection. The intravenous infusion set is mainly composed of an infusion hose, an injection needle, a flow regulator, a drip pot and a puncture device, such as an intravenous infusion needle with publication number CN103785073A, an intravenous infusion set with publication number CN106563186A and an intravenous infusion set with publication number CN108697844A. Since the total infusion volume cannot be set for such intravenous infusion sets, nurses usually need to use a syringe to extract excess liquid from the medicine bag one needle at a time according to the doctor's order before starting intravenous injection for the patient (for example, mannitol is usually 250ml / bag. If the doctor's order only requires the injection of 150ml of mannitol, the nurse needs to extract 100ml of mannitol from the medicine bag in advance). However, this process of aspirating excess liquid needle by needle is time-consuming and can easily waste precious rescue time. Utility Model Content

[0004] The purpose of the present invention is to solve the problems in the prior art and to propose an intravenous infusion component with pre-controllable infusion volume, which not only saves more preparation time and is very suitable for emergency and critical care, but also saves more labor and is easy to promote and use in major hospitals.

[0005] To achieve the above-mentioned purpose, the present invention proposes an intravenous infusion assembly with pre-controllable infusion volume, including a quantitative mechanism and an infusion mechanism. The quantitative mechanism includes a bottle body, a quantitative hose, a quantitative puncture device and a quantitative connector. The bottle body has its own scale line and the top end is indirectly connected to the quantitative puncture device through the quantitative hose, and the bottom end is installed with a quantitative connector. The quantitative mechanism can connect the bottle body with the bag body of the medicine bag by piercing the quantitative puncture device into the discharge connector of the medicine bag. The infusion mechanism can establish an infusion channel between the infusion mechanism and the human body by piercing the quantitative connector and the subcutaneous tissue at both ends respectively.

[0006] Preferably, a quantitative flow rate regulator is installed on the pipeline of the quantitative hose.

[0007] Preferably, the quantitative mechanism further comprises an exhaust pipe and an exhaust pipe cover, wherein the bottom end of the exhaust pipe is connected to the bottle body and the top end is closed by the exhaust pipe cover.

[0008] Preferably, a liquid discharge pipe is further provided at the bottom end of the bottle body, and the bottom end of the liquid discharge pipe is closed by a liquid pipe cover.

[0009] Preferably, the infusion mechanism includes an infusion hose, an infusion puncture device, a drip pot, an infusion flow rate regulator and an injection needle, the infusion puncture device and the injection needle are respectively installed at both ends of the infusion hose, and the drip pot and the infusion flow rate regulator are respectively arranged on the pipeline of the infusion hose.

[0010] Preferably, the drip pot is located between the infusion puncture device and the infusion flow rate regulator.

[0011] Beneficial effects of the utility model:

[0012] 1) By adding a quantitative mechanism consisting of a bottle, a quantitative hose, a quantitative puncture device, and a quantitative connector to the traditional infusion mechanism, the quantitative hose and quantitative puncture device can be used to inject a specified dose of liquid medicine directly from the medicine bag into the bottle with scale lines according to the doctor's instructions. The infusion mechanism then establishes an infusion channel between the quantitative mechanism and the human body to infuse the pre-controlled infusion volume of liquid medicine into the human body. Compared with the method of nurses withdrawing excess liquid from the medicine bag tube by tube, this method not only saves more preparation time, is very suitable for emergency and critical care, but also saves more labor and is easy to promote and use in major hospitals;

[0013] 2) By installing an exhaust pipe and an air pipe cover on the top of the bottle, the bottle can automatically exhaust through the exhaust pipe after receiving enough liquid medicine, thereby preventing the gas from entering the human body along with the liquid medicine;

[0014] 3) By installing a drain tube and a liquid tube cap at the bottom of the bottle, the drain tube can be used to promptly discharge excess liquid when the bottle contains too much liquid, thereby effectively improving the accuracy of the infusion volume.

[0015] The features and advantages of the present invention will be described in detail through embodiments with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] Example 1:

[0022] See Figures 1 to 3 The utility model provides an intravenous infusion assembly with pre-controllable infusion volume, including a quantitative mechanism 1 and an infusion mechanism 2. The quantitative mechanism 1 includes a bottle body 11, a quantitative hose 12, a quantitative puncture device 14 and a quantitative connector 17. The bottle body 11 has a scale line 111 and the top is indirectly connected to the quantitative puncture device 14 through the quantitative hose 12, and the bottom is equipped with a quantitative connector 17. The quantitative mechanism 1 can connect the bottle body 11 with the bag body 31 of the medicine bag 3 by piercing the quantitative puncture device 14 into the discharge connector 32 of the medicine bag 3. The infusion mechanism 2 can establish an infusion channel between the infusion mechanism 2 and the human body by piercing the quantitative connector 17 and the subcutaneous tissue at both ends respectively.

[0023] A quantitative flow rate regulator 13 is also installed on the pipeline of the quantitative hose 12. In addition, the number of the quantitative hose 12, the quantitative flow rate regulator 13 and the quantitative puncture device 14 is the same and can be one or two (when the number is two, the transfer efficiency of the drug solution between the quantitative mechanism 1 and the infusion mechanism 2 is higher).

[0024] The quantitative mechanism 1 further includes an exhaust pipe 15 and an exhaust pipe cover 16 . The bottom end of the exhaust pipe 15 is connected to the bottle body 11 and the top end is closed by the exhaust pipe cover 16 .

[0025] The infusion mechanism 2 includes an infusion hose 21, an infusion puncture device 22, a drip pot 23, an infusion flow rate regulator 24 and an injection needle 25. The infusion puncture device 22 and the injection needle 25 are respectively installed at both ends of the infusion hose 21, and the drip pot 23 and the infusion flow rate regulator 24 are respectively arranged on the pipeline of the infusion hose 21.

[0026] The drip pot 23 is located between the infusion puncture device 22 and the infusion flow rate regulator 24 .

[0027] The working process of this embodiment:

[0028] During use, the infusion puncture device 22 is first inserted into the discharge joint 32, so that the medicine liquid flows from the bag body 31 into the bottle body 11. During the initial transfer of the medicine liquid, the quantitative flow rate regulator 13 can be used to increase the flow rate, thereby improving the efficiency of the medicine liquid transfer; when the medicine liquid in the bag body 31 is close to the amount required by the doctor's order, the quantitative flow rate regulator 13 can be used to reduce the flow rate, thereby ensuring the accuracy of the medicine amount taken. After the medicine is taken, the tracheal cover 16 can be opened to exhaust the bottle body 11 through the exhaust pipe 15. Then, on the one hand, the infusion puncture device 22 is inserted into the quantitative joint 17, and on the other hand, the injection needle 25 is inserted into the subcutaneous tissue, so that the quantitative mechanism 1 is indirectly connected to the human body through the infusion mechanism 2. At this time, the medicine liquid can be transferred from the bottle body 11 to the patient's body along the quantitative joint 17, the infusion puncture device 22, the drip pot 23 and the injection needle 25. During this period, the infusion flow rate regulator 24 can also be used to adjust the infusion speed.

[0029] Example 2:

[0030] See Figure 4 The bottom end of the bottle body 11 is also provided with a liquid discharge pipe 18, and the bottom end of the liquid discharge pipe 18 is closed by a liquid pipe cover 19.

[0031] Other details are the same as those in Example 1.

[0032] The working process of this embodiment:

[0033] In this embodiment, if the amount of medicine transferred from the bag 31 to the bottle 11 exceeds the amount required by the doctor's prescription, the liquid tube cover 19 can be opened to release the excess liquid medicine from the liquid discharge tube 18.

[0034] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the scope of protection of the present invention.
