Abstract

The utility model discloses an oral cavity saliva suction tube, which comprises a main drainage tube and a tail end drainage tube made of flexible materials, wherein the front end of the tail end drainage tube is sealed, the main body of the tail end drainage tube can be completely sleeved on the main drainage tube, the tail end drainage tube is in sliding fit with the main drainage tube, and the tail end drainage tube is provided with a plurality of drainage holes from the front end to the tail end in parallel; the tail end drainage tube is in a spiral shape in a natural state. The oral cavity saliva suction tube of the utility model increases the range of the oral cavity drainage, so that the drainage tube position is not required to be frequently adjusted in the drainage process. Meanwhile, as the drainage holes are arranged in a plurality, and are arranged in parallel from the front end to the tail end of the tail end drainage tube, the problem that the oral tissue of a patient is easily attracted when the drainage airflow is large is avoided.

Description

Oral saliva suction tube

Technical Field

The utility model belongs to the technical field of medical equipment, especially, relate to a salivary duct is inhaled in oral cavity.

Background

When the teeth are extracted from the oral cavity, the patient needs to keep a relatively stable mouth opening state, a wider operation visual field is provided for a doctor, and the doctor can conveniently carry out various operations in the oral cavity. However, the patient cannot swallow the teeth for a long time in the mouth opening state, a lot of saliva appears in the oral cavity, and blood can also appear in the tooth extraction process to influence the visual field of the operation position. Therefore, during tooth extraction, the oral cavity saliva sucking pipe is generally required to suck out blood water in the oral cavity. The front end part of a drainage tube is generally arranged at a suction port of the existing oral cavity saliva suction tube, and because only one drainage hole causes that a plurality of parts in the oral cavity can not suck blood, the blood flows into the throat of a patient, and doctors need to frequently adjust the position of the drainage hole. In addition, when the drainage airflow is large, the drainage airflow is easy to attract the oral tissues of a patient, and the patient is injured.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at providing an oral cavity is inhaled salivary duct, and this oral cavity is inhaled salivary duct's characteristics and has been increaseed the scope of intraoral drainage, need not frequently to adjust the drainage tube position among the drainage process.

The utility model discloses an above-mentioned technical problem is solved to following technical means:

the utility model discloses a saliva suction tube for oral cavity, which comprises a main drainage tube and a tail end drainage tube made of flexible material, wherein the front end of the tail end drainage tube is sealed, the tail end drainage tube main body can be completely sleeved on the main drainage tube, the tail end drainage tube is in sliding fit with the main drainage tube, and the tail end drainage tube is provided with a plurality of drainage holes from the front end to the tail end in parallel; the tail end drainage tube is in a spiral shape in a natural state.

Further, the maximum diameter of the tail end drainage tube is less than 6cm when the tail end drainage tube is completely in a spiral state after being separated from the main drainage tube.

Further, the tail end of the tail end drainage tube is provided with a push-pull handle.

Further, the outer diameter of the tail end drainage tube is 5-7 mm.

Further, the tail end of the main drainage tube is made of a metal coiled tube; the metal coiled pipe is characterized by further comprising a support, and the tail end of the metal coiled pipe is fixed through the support.

The utility model has the advantages that:

the oral cavity saliva suction pipe comprises a main drainage pipe and a tail end drainage pipe made of flexible materials, wherein the front end of the tail end drainage pipe is sealed, the tail end drainage pipe body can be completely sleeved on the main drainage pipe, the tail end drainage pipe is in sliding fit with the main drainage pipe, and the tail end drainage pipe is provided with a plurality of drainage holes in parallel from the front end to the tail end; the tail end drainage tube is in a spiral shape in a natural state. The oral cavity saliva suction tube of the utility model increases the range of the oral cavity drainage, so that the drainage tube position is not required to be frequently adjusted in the drainage process. Meanwhile, as the drainage holes are arranged in a plurality, and are arranged in parallel from the front end to the tail end of the tail end drainage tube, the problem that the oral tissue of a patient is easily attracted when the drainage airflow is large is avoided.

Drawings

The invention is further described with reference to the following figures and examples.

FIG. 1 is a schematic structural view of the oral saliva sucking tube of the present invention, showing the release of the part of the drainage hole at the front end of the end drainage tube;

fig. 2 is the structural schematic diagram of the oral saliva suction tube of the utility model, and the part of the tail end drainage tube with the drainage hole is shown to be completely released.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings:

as shown in fig. 1-2, the oral cavity saliva suction tube in this embodiment includes a main drainage tube 1 and a tail end drainage tube 2 made of a flexible material, the diameter of the main drainage tube 1 is 4mm, the inner diameter of the tail end drainage tube 2 is 4mm, the outer diameter is 6mm, the front end of the tail end drainage tube is sealed, the tail end of the tail end drainage tube is provided with a push-pull handle 3, the main body of the tail end drainage tube can be completely sleeved on the main drainage tube, the tail end drainage tube is in sliding fit with the main drainage tube, and the tail end drainage tube is provided with a plurality of drainage holes 4 in parallel from the front end to the; the tail end drainage tube is in a spiral shape in a natural state. Specifically, the maximum diameter of the terminal draft tube when completely in a spiral state after being separated from the main draft tube is less than 6 cm.

The utility model discloses a use method of oral cavity saliva suction pipe: before tooth extraction, the tail end drainage tube is moved forwards relatively according to the sizes of the oral cavities of patients of different ages, the tail end drainage tube is released towards the front of the main drainage tube, the longer the releasing length of the front end of the tail end drainage tube is, the larger the diameter of the front end of the tail end drainage tube in a spiral state becomes until the maximum diameter of the front end of the tail end drainage tube in the spiral state is adaptive to the size of the inner side of the oral cavity of the patient, then the tail end of the main drainage tube is connected with a negative pressure suction device, and the negative pressure suction device is started to conduct drainage.

As a further improvement of the technical proposal, the tail end of the main drainage tube is made of a metal coiled tube 5; the metal coiled pipe is characterized by further comprising a support, and the tail end of the metal coiled pipe is fixed through the support. The metal coiled pipe can keep any shape and posture in the air, so that the tail end drainage tube can be stably kept in the oral cavity of a patient when a doctor extracts teeth, and the doctor does not need to frequently drain and adjust the position of a drainage port of the drainage tube in the operation process.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
