Description

Technical Field

[0001] The present invention relates to the field of drying technology, and in particular to a medical device drying device and method. Background Art

[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items used directly or indirectly on the human body, including the required computer software. Medical devices include medical equipment and medical consumables. At present, medical device drying plays a vital role in the medical and health field. It ensures the safety, effectiveness and stability of medical devices during storage, transportation and use.

[0003] A Chinese patent with announcement number CN218329012U discloses a glass test tube airflow drying device, including a drying cylinder, wherein the upper part of the inner cavity of the drying cylinder is divided into an airflow chamber and a drying chamber by a heat insulation plate, a drying device is installed at the bottom of the inner cavity of the drying chamber, and a supporting device is installed on the upper end surface of the drying cylinder; the drying device includes a dustproof net and a blower, the outer surface of the drying cylinder is fixedly connected to the dustproof net, the inner cavity of the drying chamber is fixedly connected to an air collecting box on one side of the dustproof net, the bottom of the inner cavity of the drying chamber is fixedly connected to the blower, and the air inlet end of the blower is connected to the air collecting box through an air inlet pipe.

[0004] When the above technical scheme is used to dry the test tube, it is necessary to energize the blower in the drying device and the heating rod in the heating box, and then the blower starts to draw outside air into the heating box through the air inlet pipe, the air collecting box and the exhaust pipe. Since a dustproof net is fixedly connected to one side of the air collecting box, the dustproof net can prevent outside dust from entering the heating box. When the air enters the heating box, the air can be heated by the heating rod in the heating box, and the heated air is discharged into the air flow cavity through the heat dissipation pipe. At this time, the hot air in the air flow cavity enters the first hollow cylinder, and then enters the second hollow cylinder and the third hollow cylinder, and is finally discharged through the drying hole. The discharged hot air can dry the glass test tube; after the test tube is cleaned, part of the water will adhere to the inner wall of the test tube. At this time, directly drying the test tube only by hot air will reduce the drying efficiency. Summary of the invention

[0007] Preferably, the slider is connected to the inner cylinder through an elastic member 1, and a water hole 2 cooperating with the water hole 1 is provided on the slider. The end of the slider has a guide surface, and when the edge of the test tube abuts against the guide surface, the slider can move axially toward the inner cylinder and connect water hole 1 with water hole 2.

[0011] Preferably, the gas distribution component is connected to the inner tube via an elastic component three, a protrusion two is mounted on the gas distribution component via an elastic component four, and a limiting groove one cooperating with the protrusion two is provided in the outer tube.

[0014] Preferably, the base plate is connected to the housing via a damping rod, and the provision of the damping rod enables the base plate to be easily reset.

[0015] A drying method for medical device drying equipment comprises the following steps:

[0016] S1: Insert the test tube upside down outside the outer tube and push the test tube downward. The air bag can gather the water on the inner wall of the test tube to the top of the air bag, so that the negative pressure pump can suck out the water through the water hole 1;

Once the tube is opened, hot air enters the test tube through the airway to dry the test tube;

[0018] S3: When the substrate moves upward and the test tube is disengaged from the stopper of the slider, the slider disengages from the groove upward and blocks the water hole, the air distribution part can inflate air into the airbag, and the retaining ring blocks the tube; through the above steps, the test tube can complete the removal of water on the inner wall of the test tube and the drying of the test tube during the downward movement, and the operation is convenient and efficient.

[0019] By adopting the above technical scheme, the beneficial effects of the present invention are as follows: when the test tube and the substrate stop and move downward, the outer periphery of the airbag in a full state can contact the inner wall of the test tube, so that the airbag can gather the water remaining on the inner wall of the test tube to the top of the airbag, so that the negative pressure pump can absorb this part of the water through water hole one, water hole two, through hole one and through hole two. After the slider enters the groove, the hot air can enter the inner ring side of the outer tube through tube one and then enter the airway through through hole five, and can be transported upward to the top of the outer tube through through hole three to achieve drying of the inner wall of the test tube. Since the airway is annular and the outer edge of the upper end of the airway has an air guide surface inclined downward, the hot air can also move downward in the annular cavity formed between the inner wall of the test tube and the outer wall of the outer tube, thereby achieving rapid drying of the inner wall of the test tube.

[0032] like Figure 1-Figure 9 As shown, a retaining ring 32 is coaxially slidably installed on the outer side of the inner cylinder 30, a tube 24 for transmitting hot air to the inner side of the outer cylinder 20 is provided at the bottom of the outer cylinder 20, and an elastic member 5 and an elastic member 6 are respectively provided at the upper and lower ends of the retaining ring 32, the elastic member 5 is specifically a fifth spring, and the elastic member 6 is specifically a sixth spring.

The end of the protrusion 321 has an arc surface 3, and a limiting groove 2 cooperating with the protrusion 321 is opened in the outer cylinder 20. In the initial state, the outer ring side of the retaining ring 32 is in a state of blocking the tube 24, and the protrusion 321 is stuck in the limiting groove 2, the slider 31 is located above the groove 201, and the water hole 1 301 and the water hole 2 310 are not connected to each other.

[0033] An airbag 22 is installed on the outside of the outer tube 20. The airbag 22 is annular. A gas distribution part 23 cooperating with the airbag 22 is installed in the outer tube 20. The gas distribution part 23 is annular and can be extended and retracted along the axial direction of the outer tube 20. The upper end of the gas distribution part 23 is fixedly connected to the outer tube 20. The gas distribution part 23 has an annular cavity inside. The annular cavity is connected to the inside of the airbag 22 through a pipeline. The gas distribution part 23 is connected to the inner tube 30 through an elastic part three. The elastic part three is specifically a third spring. The upper and lower ends of the elastic part three are respectively fixedly connected to the inner tube 30 and the gas distribution part 23. The elastic member 4 is provided with a protrusion 25, the end of the protrusion 25 has an arc-shaped surface 2, the elastic member 4 is specifically a fourth spring, and a limiting groove 1 cooperating with the protrusion 25 is provided in the outer tube 20. In the initial state, the protrusion 25 is located in the limiting groove 1, and the airbag 22 is in a full state at this time; it should be noted that the substrate 21 has a through hole 4 coaxial with the outer tube 20, the diameter of the through hole 4 is consistent with the inner diameter of the test tube and is slightly smaller than the diameter of the airbag 22 when it is in a full state, and in the initial state, the substrate 21 is located above the airbag 22 and below the slider 31.

[0034] The outer tube 20 has an air passage connected to the inner side of the air bag 22 above the air bag 22. The air passage is annular, and the outer edge of the upper end of the air passage has an air guide surface 204 inclined downward. The upper end of the outer tube 20 is provided with a plurality of through holes 303 connected to the air passage in the vertical direction, and the outer tube 20 is provided with a plurality of through holes 5 304 connecting the air passage and the inner ring side of the outer tube 20. When the retaining ring 32 is disengaged from the blocking of the tube 1 24 downward, the hot air can enter the outer tube 20 through the tube 1 24. The inner ring side then enters the airway through the through hole five 304 and can be transported upward to the top of the outer tube 20 through the through hole three 303; the outer tube 20 is provided with a through hole one 203 connecting its inner ring side and the outer ring side, the through hole one 203 is located between the airway and the airbag 22 and close to the upper end of the airbag 22, and the inner tube 30 is provided with a through hole two 302 connecting its inner ring side and the outer ring side. In the initial state, the through hole one 203 and the through hole two 302 correspond to each other and are in a connected state.

[0035] Specific working principle: Reference Figure 1-Figure 9, insert the cleaned test tube upside down on the outside of the outer cylinder 20 through the matching hole 111 and make the test tube and the base plate 21 stop, at this time, the edge of the test tube can stop with the guide surface 311 of the slider 31 so that the slider 31 moves axially toward the inner cylinder 30, and makes the water hole 1 301 and the water hole 2 310 connected, and then push the test tube downward, during this process, the outer periphery of the airbag 22 in a full state can contact the inner wall of the test tube, so that the airbag 22 can gather the water remaining on the inner wall of the test tube to the top of the airbag 22, so that the negative pressure pump can absorb this part of the water through the water hole 1 301, the water hole 2 310, the through hole 1 203 and the through hole 2 302. It can be understood that since the airbag 22 contacts the inner wall of the test tube, a negative pressure cavity is formed between the airbag 22 and the inside of the test tube, so the negative pressure pump can also exert a downward force on the test tube when it is in operation.

[0036] When the bottom of the test tube stops against the top of the inner cylinder 30, the test tube can move downward together with the inner cylinder 30, and the slider 31 moves downward into the groove 201. In this process, the through hole 1 203 and the through hole 2 302 are staggered with each other, and the elastic member 3, the elastic member 5 and the elastic member 6 are all compressed downward. When the slider 31 enters the groove 201, the protrusion 1 202 pops out and presses on the upper end of the slider 31, so that the slider 31 cannot move upward, the protrusion 3 321 suddenly disengages from the limiting groove 2, and the retaining ring 32 suddenly moves downward and disengages from the blockage of the tube 1 24, the protrusion 2 25 suddenly disengages from the limiting groove 1, and the gas distribution member 2 The lower end of 3 suddenly moves downward and sucks the gas in the airbag 22 into the annular cavity of the gas distribution part 23, so that the airbag 22 is out of contact with the inner wall of the test tube. At this time, the hot air can enter the inner ring side of the outer tube 20 through the tube 1 24 and then enter the airway through the through hole 5 304, and can be transported upward to the top of the outer tube 20 through the through hole 303 to achieve drying of the inner wall of the test tube. It should be noted that since the airway is annular and the outer edge of the upper end of the airway has an air guide surface 204 inclined downward, the hot air can also move downward in the annular cavity formed between the inner wall of the test tube and the outer wall of the outer tube 20, thereby achieving rapid drying of the inner wall of the test tube.

[0037] When the test tube is dried, stop pushing the test tube downward and turn off the negative pressure pump. At this time, the damping rod 26 can extend upward and reset, and the base plate 21 can reset and move between the airbag 22 and the slider 31. Then, after the test tube is removed, the slider 31 disengages from the test tube to allow the slider 31 to move axially away from the inner cylinder 30. When the notch 312 moves to just below the protrusion 202, under the action of the elastic member five and the elastic member six, the inner cylinder 30 moves upward and reset relative to the outer cylinder 20, the retaining ring 32 moves upward and blocks the tube 1 24, and the elastic member three pulls up the gas distribution member 23 so that the protrusion 2 25 enters the limit groove 1. The gas distribution member 23 is compressed so that the airbag 22 is in a full state again.

[0038] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
