Problems solved by technology

Stirring and suctioning the medicine in warm water will precipitate part of the medicine on the wall or bottom of the container, and it is difficult to guarantee the correct dosage, which will affect the treatment of patients
[0005] 2. Some drugs need a lot of water as a solute when they are dissolved in water, or they need to take a lot of water as a solute when they need to take multiple types of oral drugs and a large dose. However, if the patient has many underlying diseases and the heart function declines at this time, it is necessary to limit water intake to avoid Aggravating the condition, the two contradict each other, which is not conducive to the treatment of the patient, and even aggravates the condition of the patient, endangering the life of the patient.
[0006] 3. If the patient urgently needs to feed some oral medicine through the nasogastric tube, and the medicine dissolves in water for too long, use the original procedure to crush the medicine, put it in warm water, and then inject it after suction. it seems time consuming

Embodiment 1

[0031] see Figure 1-9 , the present invention provides a technical solution:

[0032] A syringe for oral medicine applied to feeding via nasogastric tube,

[0033] The device is composed of a front syringe 11, a syringe connecting part 12, a rear syringe 13, an opening 14 and a convex plate 15 through the syringe 1, and the front syringe 11, the syringe connecting part 12, the rear syringe 13 and the convex plate 15 It is an integral structure, and the opening 14 is set on the surface of the rear syringe 13 close to the position of the convex plate 15. Through the setting of the opening 14, the medical staff can pour the drug powder into the syringe 1, so that it can be used to a large extent. Using less and accurate water to mix medicines can reduce the time spent by medical staff on crushing, grinding, adding water to mix medicines, and injecting them through syringe suction. It can also avoid the generation of medicines in the grinding mixing vessel. Precipitation residu...

Embodiment 2

[0037] see Figure 1-9 , on the basis of Embodiment 1, the present invention provides a technical solution:

[0038] An oral drug injector used for feeding through a nasogastric tube. The material of the syringe 1 of the device is set to polyethylene material, and the thickness of the front syringe 11 and the rear syringe 13 is greater than that of the syringe connection part 12. The thinner wall thickness of the connecting part 12 allows the syringe 1 to be bent from the part of the syringe connecting part 12, so that the overall length of the syringe 1 becomes smaller, further making the device easy to carry;

[0039] At the same time, the front end of the needle 2 is set in a round shape to avoid insertion injuries;

[0040] And when the device is in use, it is only necessary to insert the piston 5 and the core rod 6 into the syringe 1, then fix the needle 2 on the syringe 1, add the drug powder into the syringe 1 through the opening 14, and then pass the sealing cap 3 an...

Abstract

The invention discloses an oral medicine injector applied to feeding through a nasogastric tube in the technical field of medical instruments. The oral medicine injector comprises a needle cylinder, a needle head, a piston and a core rod; the needle cylinder comprises a front needle cylinder body, a needle cylinder connecting part, a rear needle cylinder body, an opening and a protruding plate. The technical scheme of the oral medicine injector has the beneficial effects that the needle cylinder is provided with the opening, so that medical staff can pour medicine powder into the needle cylinder, then water is pumped through the device to be mixed with the medicine powder, and therefore the medicine can be mixed with small and accurate water to a large extent, and the time consumed by the medical staff in the working procedures of pulverizing, grinding, water adding and mixing, sucking through the injector and injecting can be shortened; and the situation that the correct dosage of the medicine is difficult to guarantee and the treatment of a patient is affected due to sediment residues generated by the medicine in a grinding and mixing vessel can be avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an oral medicine injector used for feeding through a nasogastric tube. Background technique [0002] Nasogastric feeding is to manually insert the gastric tube into the esophagus through the nasal cavity under special circumstances. The rod piston pumps water and food into the patient's stomach, helping patients who cannot swallow spontaneously to provide water and food, and maintain metabolism, body weight and nutrition in the body. [0003] In the daily medical process, there are three points about the problems that arise in the feeding of oral medicines through nasogastric tubes: [0004] 1. The nurse crushes the tablet (usually crushed) and puts it into water, sucks it with a syringe and injects it into the gastric tube. During this process, the tablet is usually not dissolved sufficiently (such as honeyed pills such as Angong Niuhuang Pills), and even Some drugs ar...
