Description
Technical Field
The utility model belongs to the technical field of the medical instrument technique and specifically relates to a liquid medicine draw-out device.
Background
At present, the usage and dosage of some drugs clinically infused into the vein of patients have special requirements, the infusion needs to be calculated according to the age, the body weight and the like of the patients, for example, 20 percent mannitol, sodium bicarbonate injection and the like, the total dosage of the drugs to be infused is different due to the individual difference of the patients, the packaging specifications of the drugs are single, and the clinical requirements of different patients for inputting different dosages cannot be met, so that the method that redundant drugs are sucked from the original infusion bottle and discarded, and only the required dosage is reserved in the infusion bottle is adopted clinically to complete the administration, thereby ensuring the accurate dosage of the drugs. At present, the common method of clinical nurses is to use a syringe to repeatedly suck liquid medicine and discard the liquid medicine, thereby greatly increasing the workload of nurses, increasing the phenomena of pollution of a rubber plug of an infusion bottle due to repeated puncture, falling of rubber plug scraps and the like, and causing adverse effects on patients.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a liquid medicine draw-out device is provided, have simple structure, convenient to use, can be fast the characteristics of ration extraction liquid medicine.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: a liquid medicine extracting device comprises an injection needle, a valve, a tee joint and an air bag bottle for extracting liquid medicine; the injection needle is provided with a needle seat, a branch pipe of the tee joint is provided with a conjoined rubber plug, and the injection needle is communicated with the valve, the main pipeline of the tee joint and the air bag bottle through the needle seat.
The liquid medicine extracting device further comprises an air filtering pad made of filter cotton, a step inner hole is formed in the branch pipe of the tee joint, and the air filtering pad is clamped in the step inner hole.
In the above liquid medicine extraction device, the body of the air bag bottle is provided with the raised liquid medicine capacity scale marks, and the liquid medicine capacity scale marks comprise longitudinal scale marks and transverse scale marks.
In the liquid medicine extracting device, the injection needle is in threaded connection with the valve, the main pipeline of the tee joint and the air bag bottle through the needle seat.
The utility model provides a liquid medicine extracting device, which is provided with an injection needle, a valve, a tee joint and an air bag bottle for extracting liquid medicine; the injection needle is provided with a needle seat, a branch pipe of the tee joint is provided with a connected rubber plug, and the injection needle is communicated with the valve, the main pipeline of the tee joint and the air bag bottle through the needle seat. The utility model has the beneficial technical effects that: this device is a large capacity liquid medicine suction device, can be fast accurate take out the unnecessary liquid medicine in the original medicine bottle, and the liquid medicine volume of taking out accurate control can guarantee that the patient uses medicine safely, reducible nurse's work load again. The air filter pad can ensure that clean air enters the air bag bottle to prevent the liquid medicine from being polluted. The longitudinal scale lines and the transverse scale lines are convenient for an operator to observe, the air bag bottle is in a vertical state or a flat state, the liquid medicine extracting amount can be accurately observed, and the air bag type medical nursing device has the characteristic of obviously improving the medical care operation efficiency.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is an enlarged view of a portion a in fig. 1.
The parts in the figures are numbered: the device comprises an original medicine liquid bottle 1, an injection needle 2, a needle seat 3, a valve 4, a rubber plug 5, a tee joint 6, an air bag bottle 7, longitudinal scale lines 8, transverse scale lines 9 and an air filter pad 10.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1-2, the present invention provides a liquid medicine extracting device, wherein a rubber sealing cover is arranged on the bottle mouth of an original liquid medicine bottle 1. The operation steps are as follows: firstly, the original liquid medicine bottle 1 is fixed in place. Secondly, the main pipeline of the injection needle 2, the valve 4 and the tee joint 6 is communicated with the air bag bottle 7, and the threads of all parts must be sealed well when checking. And thirdly, closing the valve 4, installing and clamping the air filter pad 10 in the step inner hole of the branch pipe of the tee joint 6, opening the rubber plug 5, forcibly pressing the air bag bottle 7 to form negative pressure in the air bag bottle, then enabling the air bag bottle to automatically expand, and enabling the outside air to enter the air bag bottle 7 through the air filter pad 10 to plug the rubber plug 5 tightly. Fourthly, the injection needle 2 is pricked into the original liquid medicine bottle 1, the valve 4 is opened, the nurse is operated to slightly squeeze the air bag bottle 7, and the air in the air bag bottle 7 enters the original liquid medicine bottle 1. Fifthly, the air bag bottle 7 is in a negative pressure state, the liquid medicine in the original liquid medicine bottle 1 is intermittently and slowly input into the air bag bottle 7 in the negative pressure state through the injection needle 2, the injection needle 2 can be pulled out when the liquid medicine amount which is pumped out reaches the requirement according to the liquid medicine capacity scale mark, and therefore the pumping-out amount of the liquid medicine can be accurately mastered. The air filter pad 10 is made of filter cotton materials, and a steel wire ring or an elastic rubber ring can be connected to the periphery of the air filter pad 10, so that the air filter pad 10 can be conveniently clamped in the inner hole of the step, and replacement is convenient.
Appropriate changes and modifications to the embodiments described above will become apparent to those skilled in the art from the disclosure and teachings herein. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and modifications and variations of the present invention are also intended to fall within the scope of the appended claims. Furthermore, although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
