Description

Technical Field

[0001] This application relates to the field of dental pulp aspiration devices, and more specifically, to a canine and feline dental pulp stem cell aspiration device. Background Technology

[0002] In dental pulp extraction, detached teeth can be wrapped in sterile gauze, crushed, and the pulp cavity exposed. The pulp tissue is then collected in centrifuge tubes for the separation of dental pulp stem cells. In existing technologies, one end of a negative pressure tube is connected to a flexible tube with suction holes. The flexible tube is inserted into the pulp cavity, and the negative pressure tube is connected to a negative pressure device to generate negative pressure. The pulp is then suctioned from the pulp cavity through the flexible tube. However, to prevent the pulp from flowing back into the flexible tube, a check valve is installed at the interface between the flexible tube and the negative pressure tube. Existing check valves are inconvenient to disassemble and clean. Therefore, we propose a canine and feline dental pulp stem cell aspiration device. Utility Model Content

[0003] To overcome the above shortcomings, this application provides a canine and feline dental pulp stem cell aspiration device, which aims to improve the problem of inconvenient cleaning of the check valve inside the tubing and negative pressure tube.

[0004] This application provides a canine and feline dental pulp stem cell aspiration device, including a negative pressure tube. A fixed tube is connected to one side wall of the negative pressure tube, and a connecting tube is also installed on the other side wall. A suction tube is threaded onto the connecting tube. A conical funnel is slidably disposed inside the suction tube. One end of the conical funnel is slidably disposed inside the fixed tube. A sealing plug is installed on the inner wall of the fixed tube, and the sealing plug is inserted into the conical funnel.

[0005] In one specific implementation, the suction tube includes a sealing tube, which is threaded onto the connecting tube, and the conical funnel is slidably disposed inside the sealing tube.

[0006] In one specific implementation, a sealing ring is fixedly fitted onto the conical funnel, and the sealing ring is slidably sealed inside the sealing tube. The conical funnel has a conical hole and a circular hole, the conical hole and the circular hole are connected, and the circular hole is fitted onto the sealing plug.

[0007] In one specific implementation, a spring is placed inside the connecting pipe and sleeved on the fixed pipe, with both ends of the spring contacting the sealing ring and the side wall of the negative pressure pipe, respectively.

[0008] In one specific implementation, the suction tube further includes a flexible tube communicating with the sealing tube, and the outer wall of the head of the flexible tube has a plurality of suction holes.

[0009] In one specific implementation, the sealing plug includes a fixing plate fixedly installed on the inner wall of the fixing tube, a connecting rod fixedly installed on one side wall of the fixing plate, a piston plate fixedly installed on one end of the connecting rod, and a circular hole sleeved on the piston plate.

[0010] In one specific implementation, an air outlet pipe is connected to the outer wall of the negative pressure pipe.

[0011] In one specific implementation, one end of the negative pressure pipe has an opening, and a sealing plate is snapped onto the opening.

[0012] The beneficial effects of this application are as follows: By connecting a fixed tube to one end of the negative pressure tube and installing a connecting tube at the other end of the negative pressure tube, a suction tube is threaded onto the connecting tube, and a conical funnel is slidably installed inside the connecting tube. A sealing plug is installed inside the fixed tube, and one end of the sealing plug is inserted into the conical funnel. When air is drawn from the negative pressure tube, a negative pressure is generated inside the negative pressure tube, causing the conical funnel to slide into the fixed tube. The inside of the conical funnel opens, allowing the dental pulp of dogs and cats to be suctioned through the suction tube, thus achieving the purpose of stem cell suction. By threading the sealing tube and the connecting tube, the conical funnel can be easily disassembled and assembled, thereby facilitating the cleaning of the suction device of this application.

Detailed Implementation

[0019] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0020] Please see Figure 1-4 This application provides a canine and feline dental pulp stem cell aspiration device, including a negative pressure tube 10. A fixed tube 20 is connected to one end of the negative pressure tube 10, and a connecting tube 30 is also installed on the other end of the negative pressure tube 10. A suction tube 40 is threaded onto the connecting tube 30. A conical funnel 50 is slidably disposed inside the suction tube 40, with one end of the conical funnel 50 slidably disposed inside the fixed tube 20. A sealing plug 60 is installed on the inner wall of the fixed tube 20 and is inserted into the conical funnel 50. Specifically, the negative pressure tube 10 is used to store canine and feline dental pulp stem cells. The negative pressure tube 10 is connected to an existing negative pressure device, causing the negative pressure tube 10 to generate negative pressure, thereby increasing the pressure... The function is to slide the conical funnel 50 into the fixed tube 20, opening the interior of the conical funnel 50, and then extracting the dental pulp from the dog or cat's teeth through the suction tube 40. The dental pulp passes through the conical funnel 50 into the fixed tube 20, and then into the negative pressure tube 10. Furthermore, the outer wall of the negative pressure tube 10 is connected to an air outlet tube 110. One end of the negative pressure tube 10 is open, and a sealing plate 120 is snapped onto the opening. The air outlet tube 110 is connected to existing negative pressure equipment, and the snapping structure between the sealing plate 120 and the negative pressure tube 10 is existing technology. By opening the sealing plate 120, the dental pulp of the dog or cat in the negative pressure tube 10 can be removed.

[0021] See Figure 4 The suction tube 40 includes a sealing tube 410, which is threaded onto the connecting tube 30. The conical funnel 50 is slidably disposed inside the sealing tube 410. It should be noted that an internal thread is provided on the inner wall of the sealing tube 410, while an external thread is provided on the outer wall of the connecting tube 30. The internal thread and the external thread are compatible, making it easy to assemble and disassemble the sealing tube 410 with the connecting tube 30, and thus easy to assemble and disassemble the conical funnel 50, achieving the purpose of easy disassembly and cleaning.

[0022] See Figure 4A sealing ring 510 is fixedly fitted on the conical funnel 50. The sealing ring 510 is slidably sealed inside the sealing tube 410. The conical funnel 50 has a conical hole 520 and a circular hole 530. The conical hole 520 and the circular hole 530 are connected. The circular hole 530 is fitted on the sealing plug 60. When set, the sealing plug 60 blocks the circular hole 530 to form a check valve. Under the negative pressure in the negative pressure tube 10, the conical funnel 50 slides into the fixed tube 20, so that the sealing plug 60 slides out of the circular hole 530, opening the circular hole 530 and communicating with the inside of the negative pressure tube 10.

[0023] See Figure 4 A spring 310 is placed inside the connecting pipe 30 and sleeved on the fixed pipe 20. The two ends of the spring 310 are respectively in contact with the sealing ring 510 and the side wall of the negative pressure pipe 10. Specifically, by setting the sealing ring 510, a receiving space is formed between the sealing ring 510 and the side wall of the negative pressure pipe 10, so that the spring 310 can be placed in the receiving space, avoiding contact between the spring 310 and the dental pulp of dogs and cats, causing contamination, and avoiding the problem of inconvenience in cleaning the spring 310. When the conical funnel 50 moves, it will drive the sealing ring 510 to squeeze the spring 310, so that the spring 310 can drive the conical funnel 50 to automatically reset, so as to achieve the purpose of check flow.

[0024] See Figure 3 The suction tube 40 also includes a flexible tube 420 connected to the sealing tube 410. Several suction holes 430 are provided on the outer wall of the head of the flexible tube 420. When set up, a negative pressure is generated inside the flexible tube 420, which causes the suction holes 430 to generate suction. The head of the flexible tube 420 is inserted into the tooth drill hole, and the dental pulp inside the tooth is extracted through the suction holes 430.

[0025] See Figure 4 The sealing plug 60 includes a fixing plate 610 fixedly installed on the inner wall of the fixing tube 20. A connecting rod 620 is fixedly installed on one side wall of the fixing plate 610, and a piston plate 630 is fixedly installed on one end of the connecting rod 620. A circular hole 530 is fitted onto the piston plate 630. Specifically, the piston plate 630 is slidably contacted with the inside of the circular hole 530, so that when the conical funnel 50 moves, the piston plate 630 moves out of the circular hole 530 and into the conical hole 520, thereby opening the circular hole 530.

[0026] When using this canine and feline dental pulp stem cell aspiration device: connect the outlet pipe 110 to an existing negative pressure device (the specific connection structure is based on existing technology). Then, place the head of the flexible tube 420 into the drilled hole in the canine or feline tooth, activate the negative pressure device, and create negative pressure inside the negative pressure tube 10. Under this pressure, the conical funnel 50 slides from the sealing tube 410 into the fixed tube 20, causing the piston plate 630 to exit the circular hole 530. The flexible tube 420 then passes through the conical funnel 50 and the fixed tube 20, connecting with the negative pressure tube. The internal connection of tube 10 creates negative pressure inside the hose 420, allowing the dental pulp inside the tooth to be drawn through the suction hole 430 and into the negative pressure tube 10. As the conical funnel 50 moves, it causes the sealing ring 510 to slide within the sealing tube 410, thereby squeezing the spring 310. After the dental pulp is drawn, the negative pressure device is turned off, and the spring 310 will drive the sealing ring 510 to reset, so that the circular hole 530 is fitted onto the piston plate 630, achieving the purpose of sealing.

[0027] It should be noted that the specific models and specifications of the negative pressure pipe 10 and the hose 420 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0028] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application. It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
