Description

Technical Field

[0001] The present invention relates to the field of dental technology, and in particular to a wearable adsorption device beside a dental chair and a manufacturing method thereof. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] In dental clinics, commonly used treatment instruments include high-speed handpieces (350,000 to 420,000 revolutions per minute) 、 Three-purpose air gun 、 Ultrasonic cleaning 、 Ultrasonic bone knives, etc., these instruments will generate droplets, dust and aerosols during use due to high-speed rotation and high-frequency vibration. Aerosols can carry harmful substances such as bacteria, viruses and parasite eggs, and after floating to a long distance with the airflow, they adhere to the skin mucosa, respiratory tract, digestive tract and wound surface of the human body, causing infection. They are contagious and pathogenic. Dust can be inhaled into the body by doctors and patients, causing potential infection and chronic lung disease. During the treatment process of tooth cutting and restoration, which requires the use of ultrasonic equipment and high-speed mobile phones, the amount and spread of droplets, dust and aerosols will increase rapidly.

[0004] The existing chair-side suction equipment for droplets, dust and aerosols is a strong suction straw + a plastic disposable suction head built into the left side of the dental chair. The assistant sits on the left side of the dental chair and uses the handheld suction device to track and absorb droplets, dust, aerosols and other splashes outside the patient's mouth. There are the following problems:

[0005] 1) The area that a single suction head can absorb is limited, and it is not possible to fully absorb splashes as comprehensively as possible;

[0006] 2) During the tooth grinding process, larger particles are directly sucked into the strong suction pipe along with the flying dust, which may block the strong suction pipe. The strong suction pipe needs to be cleaned regularly, which increases the labor and time costs of equipment maintenance and increases the risk of cross infection;

[0007] 3) Moreover, when the assistant is performing the strong suction operation, he cannot use his left hand to complete other operations at the same time, which greatly affects the assistant's work efficiency;

[0008] 4) The plastic disposable pipette tip is directly inserted into the strong suction straw. During use, the strong suction straw's own weight and air pressure may cause the pipette tip to detach from the strong suction straw, which increases the operation time, increases the risk of affecting the operator's operation, and increases the medical cost of replacing the disposable pipette tip.

DETAILED DESCRIPTION

[0044] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0045] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless otherwise explicitly stated in the present invention, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof;

[0046] As introduced in the background technology, the strong suction tube in the prior art needs to be operated by an assistant alone and has limited adsorption capacity. In order to solve the above technical problems, the present invention proposes a wearable adsorption device next to a dental chair.

[0047] Embodiment 1

[0048] In a typical embodiment of the present invention, reference is made to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a wearable adsorption device for use next to a dental chair includes a dust box 4, a filter screen 14 is arranged in the dust box 4, the dust box 4 can be worn on the back of the hand, one end of the dust box 4 is connected to at least two straws 1 respectively, suction is performed through the straws 1, the straws 1 are movably connected to the dust box 4, the straws 1 are connected to the finger sleeves 2, the finger sleeves 2 can be stuck on the fingers, the length of the finger sleeves 2 is smaller than the length of the straws 1, the other end of the dust box 4 is movably connected to the connecting tube 7, and the end of the connecting tube 7 away from the dust box 4 is detachably connected to the strong suction pipe head 11.

[0049] In order to prevent the connecting tube 7 from being separated from the strong suction pipe head 11 during use, a sleeve 8 is sleeved on the end of the connecting tube 7 away from the dust storage box 4, and the sleeve 8 has a set length. The strong suction pipe head 11 is snap-connected with the end of the connecting tube 7, and the sleeve 8 is located in the circumferential direction of the strong suction pipe head 11. The spring clip 9 can be detachably clamped on the outside of the sleeve 8 to clamp the sleeve 8 and the strong suction pipe head 11.

[0050] In this embodiment, reference Figure 5 and Figure 6 As shown, a conical section 12 is provided at one end of the connecting tube 7 away from the dust storage box 4, and the conical section 12 can be inserted into the strong suction pipe head 11. The connecting tube 7 is connected to the sleeve 8, and an insertion space for the strong suction pipe head is formed between the sleeve and the conical section. A limiting ring 13 is provided at the conical section of the connecting tube 7, and the limiting ring 13 is used to be fixedly connected to one end of the sleeve. The conical section 12 is provided on the connecting tube 7, which is not only convenient for quick connection with the strong suction pipe head 11, but also can be adapted to strong suction pipe heads 11 of different sizes, thereby facilitating quick connection between the two.

[0051] refer to Figure 7 As shown, the sleeve 8 is hollowed out to expose the button at the head 11 of the strong suction pipe. Specifically, the sleeve 8 includes a fixing ring, which is fixedly connected to the limiting ring 13 at the connecting pipe 7, and the fixing ring is connected to the half ring 10. The arrangement of the half ring 10 allows the button at the head of the strong suction pipe to be exposed from the hollow part of the sleeve 8.

[0052] In other examples, the sleeve 8 is made of a flexible material such as rubber, so that the sleeve can be matched with strong straw heads 11 of different sizes to enhance the overall applicability; because the strong straw head 11 has a concave ring in the annular direction, a convex strip is provided on the inner side of the half ring 10 of the sleeve 8 to match the concave ring.

[0053] It is easy to understand that reference Figure 7 As shown, a slot 15 is provided in the annular direction of the sleeve, and the spring clip 9 is clamped in the annular direction of the sleeve 8 along the slot 15. The slot 15 can be provided at two locations, and two corresponding spring clips 9 are provided. The interval between two adjacent spring clips 9 is set, and the width of the slot 15 is adapted to the width of the spring clip 9. Moreover, the use of the spring clip 9 ensures the reliability of the connection between the entire device and the strong suction tube head 11, ensures the operation time, avoids affecting the operator, and reduces the increase in medical costs caused by replacing the entire device.

[0054] It can be understood that in some examples, three, four or five straws 1 are provided, and a distance is set between two adjacent straws 1. Considering that the fingers need to be opened or closed, the wrist will swing relative to the arm, and a first bellows 3 is provided at one end of the straw 1 connected to the dust box 4 so that the straw 1 can be movably arranged relative to the dust box 4 under the drive of the finger sleeve 2; a second bellows 6 is provided at one end of the connecting tube 7 connected to the dust box 4; in this way, the straw 1 can move relative to the dust box 4 as the angle between the fingers increases, and the connecting tube 7 can also move relative to the dust box 4 as the wrist swings, thereby ensuring usage requirements.

[0055] It should be noted that, in some examples, the finger sleeve 2 is a ring-shaped piece, as long as the finger can pass through it; or, a notch is provided on the side of the finger sleeve 2 away from the straw 1, and the notch is provided along the length direction of the finger sleeve 2. The finger sleeve 2 can specifically be made of plastic with a certain elasticity, so that the finger sleeve can be suitable for hands of different sizes. The length of the finger sleeve 2 is adapted to the length of the third knuckle of the finger, so that the finger sleeve 2 can be stuck at the third knuckle of the finger.

[0056] In this embodiment, the length of the dust storage box 4 is adapted to the length of the back of a person's hand, the width of the dust storage box 4 is adapted to the width of the back of a person's hand, the dust storage box 4 has a set thickness, the thickness of the dust storage box 4 is greater than the diameter of the straw 1, the inner side of the dust storage box 4 is an arc surface so that the inner side of the dust storage box can fit the back of the hand, and arc-shaped clamping plates 5 are respectively arranged on both sides of the inner side of the dust storage box 4, and the arc-shaped clamping plates 5 on both sides are arranged oppositely, and the arc-shaped clamping plates 5 are bent toward the inner side of the dust storage box so that the arc-shaped clamping plates on both sides can be clamped at the base of the index finger and the base of the little finger of the palm of the hand;

[0057] In addition, refer to Figure 6 As shown, the filter 14 is arranged along the diagonal surface of the dust storage box 4 to increase the setting area of ​​the filter 14. The filter 14 has a plurality of mesh holes, and the mesh holes are arranged in multiple rows and columns. The inner diameter of the mesh holes is smaller than the diameter or width of the particles that are easy to clog the strong suction pipe. The inner diameter is determined according to the size of the particles generated during the tooth grinding process to prevent larger particles from entering the strong suction pipe head 11 and the strong suction pipe through the connecting pipe 7.

[0058] It can be understood that a slope is provided at one end of the straw 1 away from the dust storage box 4, and the slope is inclined toward the direction of the finger sleeve, so that when a person's finger is bent, the slope side of the straw 1 can be directed to the position to be adsorbed, and the slope effectively ensures the adsorption area of ​​the straw 1.

[0059] It is easy to understand that the straw 1 is made of hard plastic to avoid collapse and deformation during finger movement and under strong suction negative pressure, which affects the adsorption efficiency; the dust storage box 4 is also made of hard plastic to avoid deformation under strong suction pressure.

[0060] It should be explained that the strong suction pipe head 11 is the head of the strong suction pipe, and the strong suction pipe head 11 is an existing structural component, which is usually conical.

[0061] Furthermore, in this embodiment, the entire device can be made of disposable material.

[0062] The dust storage box 4 provided in this embodiment can be worn on the left hand side. The dust storage box 4 is provided with at least two straws 1. The straws 1 are fixed to one side of the fingers through the finger sleeves 2. The whole can realize the simultaneous operation of multiple straws 1, and effectively ensure the adsorption range. The dust storage box 4 can be worn on the back of the hand, so there is no need for people to hold the entire device to work. After wearing it on the back of the hand, the hand moves the entire device, and the work can be carried out through the straws 1. At this time, the hand can hold other machines to perform related operations. In this way, operation and adsorption can be carried out simultaneously with one hand, and droplets and aerosols can be effectively sucked out as a whole, the probability of disease transmission is reduced, and the work efficiency of assistants is effectively improved.
