Description
Technical Field
The utility model relates to the technical field of medical equipment, especially, relate to disposable dentistry washing needle.
Background
Under the development of modern science and technology, people pay more and more attention to oral health, particularly tooth health, endodontics is the most common mode for treating tooth diseases, is the most common internationally effective treatment method for endodontic diseases and periapical diseases, effective cleaning is the key of treatment, and the oral cavity is cleaned through flushing;
in the prior art, the liquid outlet end of the washing needle is arranged in an inclined shape, so that the oral cavity is conveniently washed, and the oral cavity is washed through the liquid outlet hole in the side wall of the washing needle;
in the prior art, the liquid outlet end of the flushing needle is obliquely fixed at the liquid outlet end of the needle tube, and the liquid outlet end does not have the function of adjustment, so that the liquid outlet direction of the liquid outlet end is certain, flushing can not be realized aiming at the inner side of teeth in a cavity, flushing is inconvenient, the flushing efficiency of the flushing needle is reduced, and the use flexibility of the flushing needle is reduced;
in the prior art, the flushing liquid is pushed to the liquid outlet end, so that the water volume and the water pressure of the liquid outlet end are increased, a patient carelessly swallows the flushing liquid and a flushing object together, the pressure and the liquid outlet volume of the flushing liquid are uncontrollable, discomfort is brought to the patient, and therefore a disposable dental flushing needle is provided.
Disclosure of Invention
According to the technical problem, the utility model provides a disposable dentistry washing needle which is characterized in that the disposable dentistry washing needle comprises a needle seat, a needle tube, a universal tube and a nozzle, wherein the needle tube is installed on the needle seat, the needle tube and the needle seat are of an integral structure, the inner side wall of the liquid outlet end of the needle tube is provided with a thread, the liquid outlet end of the needle tube is provided with the universal tube through the thread, the outer side wall of the universal tube is provided with a thread, the universal tube is provided with the nozzle through the thread, the inside of the nozzle is of a hollow structure, the side wall of the nozzle is provided with liquid outlet holes, the number of the liquid outlet holes;
the diameter of the liquid inlet end of the nozzle is 3mm larger than that of the liquid outlet end of the needle tube.
The utility model has the advantages that: the utility model discloses be provided with the universal tube through the screw thread at the top of needle tubing, this universal tube is soft plastics material, the universal tube passes through the screw thread and is connected with the nozzle, the universal tube of soft plastics material has stronger extensibility, make can realize the rotation to the nozzle through the universal tube, the angle modulation to the nozzle has been realized, when needing to wash the inboard of the inside tooth of patient's oral cavity, medical staff realizes reaching the angle modulation to the nozzle through the universal tube of rotating soft plastics material, medical staff can wash the tooth inboard, be convenient for wash the tooth inboard, the efficiency of washing is improved, the flexibility of this application use is improved;
the utility model discloses set the diameter of nozzle inlet to 3mm more than the diameter of needle tubing liquid outlet, can effectively reduce the velocity of flow in the flush fluid gets into the spray tube for the velocity of flow can slow down to some extent, thereby reduced water yield and water pressure in the nozzle, make water yield and water pressure obtain effective control, avoid because the relation of water yield and pressure makes the patient carelessly with the flush fluid with wash the thing together swallow, the circumstances such as uncomfortable that bring for the patient take place, improved the reliability.
Drawings
FIG. 1 is a schematic view of the overall structure of the present invention;
fig. 2 is an enlarged view of the position A of the present invention.
As shown in the figure, 1-a needle seat, 2-a needle tube, 3-a universal tube, 4-a nozzle and 5-a liquid outlet.
Detailed Description
Example 1
The utility model provides a disposable dentistry washing needle, its characterized in that includes needle file 1, needle tubing 2, universal tube 3, nozzle 4, install needle tubing 2 on the needle file 1, needle tubing 2 and needle file 1 structure as an organic whole, the inside wall of the play liquid end of needle tubing 2 has seted up the screw thread, the play liquid end of needle tubing 2 has installed universal tube 3 through the screw thread, the lateral wall of universal tube 3 is provided with the screw thread, install nozzle 4 through the screw thread on the universal tube 3, the inside of nozzle 4 is hollow structure, seted up liquid outlet 5 on the lateral wall of nozzle 4, the quantity of liquid outlet 5 is M, M is more than or equal to 2;
the diameter of the liquid inlet end of the nozzle 4 is 3mm larger than that of the liquid outlet end of the needle tube 2.
Example 2
When the utility model is used, the flushing fluid in the needle seat 1 is pushed into the needle tube 2, the flushing fluid in the needle tube 2 is pushed into the nozzle 4, the flow speed in the pushing process is reduced, the pressure is reduced, the diameter of the liquid inlet of the nozzle 4 is set to be 3mm larger than that of the liquid outlet of the needle tube 2, the diameter difference between the two is 3mm, the flow speed of the flushing fluid entering the spray tube can be effectively reduced, the flow speed can be slowed down, the water quantity and the water pressure in the nozzle 4 are reduced, the water quantity and the water pressure are effectively controlled, the situation that the patient cares that the flushing fluid and flushing objects are swallowed together unconsciously due to the relation between the water quantity and the pressure, the discomfort brought to the patient is avoided, the reliability is improved, when the inner side of the teeth of the patient needs to be flushed, the angle adjustment of the nozzle 4 needs to be carried out, the medical staff rotates the universal tube 3, the realization reaches the angular adjustment to nozzle 4 to the rotation of universal pipe 3, and medical staff can wash the tooth inboard, is convenient for wash the tooth inboard, has improved the efficiency of washing, has improved the flexibility that this application used, and 5 spouts of play liquid hole on the flush fluid follow nozzle 4 wash the tooth inboard, and this application is disposable device, and convenient operation has improved the security.
