Description

An oral sprayer suitable for patients with difficulty opening their mouth

Technical Field

The utility model belongs to the technical field of medical care, and in particular relates to an oral sprayer suitable for patients with difficulty in opening their mouths.

Background technique

Chinese patent announcement number CN217245985U discloses an oral sprayer, comprising: a bottle body, a pump head is arranged on the top side of the bottle body; a spray tube, one end of which is connected to the pump head, the other end of the spray tube is an output end, a plurality of first spray outlets are arranged on the outer wall of the spray tube, the spray tube is arranged with a second spray outlet, and an atomizer is arranged in the spray tube; an adjusting cylinder, which is rotatably connected to the outer side of the spray tube, a first avoidance port is arranged on the outer wall of the adjusting cylinder, a first shielding portion is formed at a position between any two adjacent first avoidance ports on the adjusting cylinder, a second shielding portion is arranged at one end of the adjusting cylinder, the second shielding portion covers the second spray outlet, and the first shielding portion covers the first spray outlet and the second shielding portion opens the second spray outlet when the adjusting cylinder is rotated. The utility model can switch the spray mode according to the use needs, and can not only uniformly moisten the inside of the oral cavity, but also moisten only a local position, which not only improves the use efficiency, but also improves the use comfort of the patient.

However, the device has the following defects when used: when the device is applying medicine to the patient's mouth, in order to evenly apply the medicine inside the mouth, the patient needs to open his mouth several times and adjust the position of the spray tube in the patient's mouth several times. However, when the device is used for patients who have difficulty opening their mouths, the patient's teeth will involuntarily bite the spray tube due to the difficulty of opening their mouths, making it difficult to adjust the position of the spray tube in the mouth, which is inconvenient for the operator to use. Therefore, we propose an oral sprayer suitable for patients with difficulty opening their mouths.

Utility Model Content

The utility model aims to provide an oral sprayer suitable for patients with difficulty in opening their mouths, so as to solve the technical problems raised in the background technology.

To achieve the above-mentioned purpose, the specific technical scheme of the utility model is as follows: an oral sprayer suitable for patients with difficulty in opening their mouths, comprising a liquid medicine bottle, a nozzle being threadedly connected to the left side of the liquid medicine bottle, a nozzle being fixedly mounted on one end of the nozzle away from the liquid medicine bottle, a direction adjustment structure being arranged on the surface of the nozzle, and a liquid supply structure being arranged on the upper surface of the liquid medicine bottle;

The direction adjustment structure includes a sleeve, a bite plate is fixedly installed on the surface of the sleeve, a circular groove is opened on the inner wall of the sleeve, a sphere is rotatably connected to the inner wall of the circular groove, a through hole is opened on the surface of the sphere, and the surface of the nozzle is slidably connected to the inner wall of the through hole.

Preferably, the liquid supply structure includes a liquid storage cylinder fixedly mounted on the inner wall of the medicine liquid bottle, the upper end of the liquid storage cylinder extends to the outside of the medicine liquid bottle, a piston is slidably mounted on the inner wall of the liquid storage cylinder, a push rod is fixedly mounted on the upper surface of the piston, a handle is fixedly mounted on the upper end of the push rod, a liquid inlet pipe and a liquid outlet pipe are respectively fixedly mounted on the surface of the liquid storage cylinder, a medicine injection port is fixedly mounted on the upper surface of the medicine liquid bottle, a sealing cap is threadedly connected to the inner wall of the medicine injection port, and an air inlet hole is opened on the upper surface of the sealing cap.

Preferably, a compression spring is sleeved on the surface of the push rod, one end of the compression spring is fixedly connected to the lower end of the handle, and the other end of the compression spring is fixedly connected to the upper end of the liquid storage cylinder.

Preferably, one-way valves are provided on the inner wall of the air inlet hole, the surfaces of the liquid inlet pipe and the liquid outlet pipe.

Preferably, the nozzle and the nozzle are arranged perpendicular to each other.

Preferably, there are two bite plates, which are symmetrically arranged on the surface of the sleeve, and the material of the bite plates is made of silicone.

The oral sprayer of the utility model suitable for patients with difficulty in opening the mouth has the following advantages:

1. This oral sprayer is suitable for patients with difficulty in opening their mouths. By setting a universal adjustment structure, a bite plate is placed between the patient's upper and lower teeth, and the patient is forced to bite the bite plate. Then, the nozzle is driven to slide along the inner wall of the through hole, thereby changing the depth of the nozzle to the oral cavity. At the same time, the swinging nozzle can drive the ball to rotate along the inner wall of the sleeve, thereby changing the left and right position of the nozzle in the oral cavity. Moreover, the nozzle and the nozzle are set at 90 degrees. When the nozzle is rotated, the nozzle can be driven to rotate, thereby flexibly changing the position of the nozzle in the oral cavity without the patient repeatedly opening his mouth, which is convenient for the operator to use.

2. This oral sprayer suitable for patients with difficulty opening their mouths has a liquid supply structure. Pressing the push rod downward can drive the piston to descend, thereby driving the liquid in the liquid storage cylinder to be discharged into the nozzle along the liquid outlet pipe. At the same time, loosening the push rod can drive the piston to reset using the force of the compression spring, so that the liquid in the liquid bottle can be sucked into the liquid storage cylinder using the liquid inlet pipe, thereby making the dosage of the liquid sprayed each time consistent, and preventing excessive liquid from being sprayed out of the oral cavity.
