Detailed Description
The first embodiment is as follows:
as shown in figure 1, the oral medical saliva suction tube in the first embodiment comprises a suction head 1, a suction tube 2 and a porous soft cap 3. One end of the suction pipe 2 is connected with the continuous negative pressure device, and the other end is tightly connected with the suction head 1. Referring to fig. 2, 3 and 4, it can be seen that the suction head 1 is provided with six side suction holes 11, and the side suction holes 11 are U-shaped and uniformly arranged along the circumferential direction of the suction head 1.
As can be seen from figures 1, 3 and 4, the porous soft cap 3 is sleeved on the suction head 1 and covers the side suction holes 11. The porous soft cap 3 is made of cotton. The cotton is covered around the suction head 1 and is in a bulky shape. As can be seen from fig. 5, in clinical operation, due to the negative pressure, the cotton material of the porous soft cap is firmly adsorbed on the side suction holes 11. In addition, the cotton can form a thin layer to be adsorbed on the suction head by the water mist in the oral cavity. At the moment, due to the protection of cotton, the side suction holes can not directly contact and suck the mucous membrane, so that the adsorption stress to the mucous membrane of the oral cavity is reduced, and the mucous membrane of the oral cavity is prevented from being broken by negative pressure. In addition, the cotton is made of porous materials, liquid in the oral cavity can still enter the suction head, and the saliva suction efficiency cannot be influenced. In addition, the pores in the cotton can filter large solid debris in the oral cavity and prevent the solid debris from blocking a saliva sucking channel. Cotton is elastic and in direct contact with mucosal surfaces. Under the action of negative pressure, the materials have a buffer effect, and the mucous membrane surface cannot be subjected to large adsorption stress instantaneously. Therefore, even if the pressure of the negative pressure device is not adjusted, the mucous membrane of the oral cavity is not damaged, and the working efficiency is greatly improved.
Example two:
the difference between the second embodiment and the first embodiment is the shape and material of the porous soft cap, and the material of the porous soft cap 3 is sponge. The sponge is easier to form than cotton, can be processed into a regular cylinder shape, is more convenient to install, and can be directly sleeved into the suction head 1. The cylindrical porous soft cap 3 is directly sleeved on the suction head 1. In clinical operation, the sponge material can be firmly adsorbed on the side suction holes 11 due to the negative pressure. Due to the protection of the sponge, the side suction holes can not directly contact and suck the mucous membrane, so that the adsorption stress to the oral cavity mucous membrane is reduced, and the oral cavity mucous membrane is prevented from being broken by negative pressure. In addition, the sponge is also made of porous materials, so that liquid in the oral cavity can still enter the suction head, and the saliva suction efficiency cannot be influenced. In addition, the pores in the sponge can filter large solid debris in the oral cavity and prevent the solid debris from blocking a saliva sucking channel. Likewise, the sponge is elastic and is in direct contact with the mucosal surface. Under the action of negative pressure, the materials have a buffer effect, and the mucous membrane surface cannot be subjected to large adsorption stress instantaneously. Therefore, the pressure of the negative pressure device is not regulated, the oral mucosa is not damaged, and the working efficiency is greatly improved.
Example three:
the third embodiment differs from the first and second embodiments in the shape of the side suction holes of the suction head 1. The hole is inhaled to side in this embodiment for the circular port, and the top end face of suction head is the plane. Avoid because of the structural shape sudden change, oral mucosa because of the suction effect, form the deformation corresponding with the structural shape to lead to oral mucosa stress concentration, cause the mucosa damage.
The oral medical saliva sucking tube is not limited to the materials of the first embodiment and the second embodiment, and the porous soft cap can also be made of porous soft materials such as thin silk cloth, thin linen and the like, and the structural shape of the porous soft cap is similar to that of the porous soft cap made of sponge materials. The suction head and the suction pipe are not limited to the clamping connection in the first embodiment and the second embodiment, and a threaded connection or a suction head and a suction pipe which are integrally formed can be adopted. The side suction holes are not limited to the U-shaped holes and the circular holes, and square holes, elliptical holes and the like can be adopted, and the side suction holes belong to the equivalent technical scope of the invention.
The present invention is not limited to the above-described embodiments, and various changes and modifications of the present invention are intended to be included within the scope of the claims and the equivalent technology of the present invention if they do not depart from the spirit and scope of the present invention.
