Description

Technical Field

[0001] This utility model relates to the field of dental medical device technology, and in particular to a disposable blood-absorbing pen for dental use. Background Technology

[0002] When performing a filling, the cavity is below the gum line, which requires cutting away the covering gum. After cutting, there will be bleeding and seepage. However, a dry environment is required for fillings. Current oral suction tubes cannot dry out small amounts of blood in narrow gaps, which poses a challenge to fillings. To address this, we propose a disposable blood suction pen for dentistry. Utility Model Content

[0003] The main purpose of this invention is to provide a disposable blood-absorbing pen for dentistry, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A disposable blood-absorbing pen for dentistry includes a blood-absorbing pen barrel, one end of which is fixedly connected to a universal tube, the other end of which is connected to a connector, the other end of which is connected to absorbent resin, the other end of which is covered with a gauze sleeve, and a suction cup fixedly installed at the other end of the blood-absorbing pen barrel, with a magnet fixedly installed in the middle of the suction cup.

[0006] Preferably, an external threaded rod is fixedly installed at the end of the universal tube connected to the connector.

[0007] Preferably, the end of the connector that connects to the universal tube has an internal threaded hole, and the universal tube is connected to the connector by being screwed into the internal threaded hole through an external threaded rod.

[0008] Preferably, the end of the connector that connects to the absorbent resin has a slot, and the end of the absorbent resin that connects to the connector has a fixedly installed connecting resin block. The absorbent resin is embedded in the slot and connected to the connector through the connecting resin block.

[0009] Preferably, the curved surface of the absorbent resin has an anti-detachment groove, and an elastic band is fixedly installed on the edge of the absorbent resin. The gauze sleeve is inserted into the anti-detachment groove by the elastic band and is fixedly attached to the end face of the absorbent resin.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] In this invention, the disposable blood-absorbing pen for dentistry can adjust the angle of the absorbent resin through a universal tube to adapt to the operating angle required by the doctor. During absorption, the absorbent resin can directly and quickly absorb the flowing blood, thus providing a dry surgical environment for dental fillings. Furthermore, the connector can be directly detached from the end of the universal tube, allowing the used absorbent resin to be disassembled and replaced with new one. This can greatly save on production raw materials, reduce medical waste, and is more environmentally friendly. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Example 1:

[0018] like Figure 1-3 As shown, a disposable blood-absorbing pen for dentistry includes a blood-absorbing pen barrel 1, one end of which is fixedly connected to a universal tube 2, the other end of which is connected to a connector 3, the other end of which is connected to a water-absorbing resin 4, the other end of which is covered with a gauze sleeve 5, and the other end of which is fixedly installed with a suction cup 6, and a magnet 7 is fixedly installed in the middle of the suction cup 6.

[0019] The universal tube 2 and the connector 3 are connected at the end with an external threaded rod 21. After the universal tube 2 is connected to the connector 3 through the external threaded rod 21, the universal tube 2 can be bent at will, thereby adjusting the angle between the absorbent resin 4 and the blood-absorbing pen 1. This makes it more convenient for doctors to adjust to a suitable angle for operation, and is more flexible and adaptable.

[0020] The end of the connector 3 that connects to the universal tube 2 has an internal threaded hole 31. The universal tube 2 is screwed into the internal threaded hole 31 through the external threaded rod 21 and connected to the connector 3. The universal tube 2 is screwed into the slot 32 through the external threaded rod 21 and fixedly connected to the connector 3. With this structure, the absorbent resin 4 used by the connector 3 can be disassembled and discarded, and then a new connector 3, absorbent resin 4 and gauze cover 5 can be replaced, thereby avoiding the disposal of the universal tube 2 and the blood-absorbing pen barrel 1, which is more environmentally friendly.

[0021] The end of the connector 3 that connects to the absorbent resin 4 is provided with a slot 32, and the end of the absorbent resin 4 that connects to the connector 3 is fixedly installed with a connecting resin block 41. The absorbent resin 4 is embedded in the slot 32 through the connecting resin block 41 and connected to the connector 3.

[0022] The curved surface of the absorbent resin 4 has an anti-detachment groove 42, and a rubber band 51 is fixedly installed on the edge of the absorbent resin 4. The gauze sleeve 5 is inserted into the anti-detachment groove 42 through the rubber band 51 and is fixedly attached to the end face of the absorbent resin 4.

[0023] It should be noted that this utility model is a disposable blood-absorbing pen for dentistry. In use, the new absorbent resin 4 is connected to the external threaded rod 21 through the internal threaded hole 31 and then to the universal tube 2. After connection, the gauze sleeve 5 is fixed to the end of the absorbent resin 4 by the rubber band 51, which is embedded in the anti-detachment groove 42 for fixation. During use, the doctor can contact the end of the absorbent resin 4 with the gauze sleeve 5 to the blood flowing from the teeth. In this way, the absorbent resin 4 can absorb the blood, thereby achieving rapid drying and keeping the oral treatment area dry. After use, the connector 3 and the universal tube 2 can be disassembled. The universal tube 2 and the blood-absorbing pen barrel 1 can be made of stainless steel. After disassembly, they can be sterilized at high temperature and reused, which is more environmentally friendly. In addition, the provided magnet 7 and suction cup 6 can be used for adsorption, which is convenient for temporary placement of the blood-absorbing pen during surgery and avoids contamination of the end of the absorbent resin 4. The magnet 7 can be directly adsorbed on the iron instrument surface, while the suction cup 6 can be adsorbed on smooth plastic, tile, metal and wood surfaces, making up for the lack of fixation of the magnet 7.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
