Description

Technical Field

[0001] This invention relates to the field of medical cable technology, specifically to a high-strength medical cable with antibacterial function and its manufacturing process. Background Technology

[0002] Cables are devices for transmitting electrical energy or signals, mainly consisting of a conductor covered by an insulation layer. Medical cables are used in medical equipment. In addition to the strong insulation and anti-interference capabilities of ordinary cables, they also need to have antibacterial functions. In existing technology, the most common method is to add antibacterial components to the outer insulation layer of the cable, so that the cable surface has a certain antibacterial effect to reduce cross-contamination when medical personnel or patients come into contact with the cable. However, in actual use, since the contaminants attached to the cable surface usually have a certain thickness, such as various bodily fluids and coupling agents, only the side in contact with the cable surface can effectively inhibit bacteria. The outer side, due to the thickness of the attached substances, does not come into contact with the cable and is difficult to effectively inhibit bacteria. Moreover, the outer side is more likely to come into contact with the human body, causing cross-contamination problems. Summary of the Invention

[0003] The purpose of this invention is to provide a high-strength medical cable with antibacterial function and its manufacturing process, so as to solve the problem that existing medical cables are difficult to effectively inhibit bacteria as mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a high-strength medical cable with antibacterial function, comprising an insulating sheath and antibacterial components, wherein the antibacterial components are sleeved on the outside of the insulating sheath, and a track control strip is embedded in the surface of the insulating sheath, through which the antibacterial components are powered; the antibacterial components include a main control sleeve and a pivot sleeve, wherein the pivot sleeve is axially reciprocating relative to the main control sleeve, and a locking sleeve is fixedly installed at one end of the main control sleeve and on the pivot sleeve, wherein the locking sleeve can lock relative to the insulating sheath when energized; through the axial reciprocating movement of the pivot sleeve relative to the main control sleeve, and in conjunction with the energization control of the locking sleeve, the antibacterial components move axially along the outer surface of the insulating sheath; an ultraviolet lamp is installed inside the main control sleeve, through which ultraviolet light is emitted to sterilize the surface of the insulating sheath.

[0005] A partition inner ring and a pneumatic inner ring are fixedly installed on the inner wall of the main control sleeve, and the ultraviolet lamp is installed between the partition inner ring and the pneumatic inner ring.

[0006] A cylindrical groove is formed on the inner ring of the separator, and a piston-type contact is provided in the cylindrical groove. The piston-type contact is in airtight contact with the inner wall surface of the cylindrical groove. The piston-type contact is in sliding conductive contact with the track electrical control bar. A central air passage is formed through the inside of the piston-type contact. A connecting spring is provided inside the cylindrical groove. The connecting spring applies elastic pressure to the piston-type contact, so that the piston-type contact and the track electrical control bar remain in contact.

[0007] The inner ring of the pneumatic ring has an inner ring chamber, and a compression push plate is provided in the inner ring chamber. A push plate top shaft is fixedly provided on the compression push plate. The push plate top shaft passes through the side wall of the main control sleeve and extends out from the end of the main control sleeve.

[0008] A positioning shaft is fixedly installed inside the inner ring chamber. The positioning shaft passes through the extrusion push plate and limits the extrusion push plate. An air inlet groove is opened through the side wall of the inner ring chamber to the outside.

[0009] The inner ring chamber is equipped with an air bladder. When the axial sleeve moves axially toward the main control sleeve, the axial sleeve will press against the push plate top shaft. The push plate top shaft drives the compression push plate to move, so that the compression push plate compresses the air bladder. The inner ring of the air pressure is also provided with an air inlet channel and an air outlet channel. One end of the air inlet channel is connected to the air bladder, and the other end is connected to the inner cavity of the inner ring chamber. One end of the air outlet channel is connected to the air bladder, and the other end is connected to an external connecting pipe, which is connected to the cylindrical groove.

[0010] The intake channel is provided with a first one-way valve, and the exhaust channel is provided with a second one-way valve. The first one-way valve causes the gas in the intake channel to flow unidirectionally toward the airbag, and the second one-way valve causes the gas in the airbag to flow unidirectionally toward the exhaust channel.

[0011] An axial spring is provided between the main control sleeve and the axial sleeve. A magnetic ring is provided inside the main control sleeve, and a telescopic coupling is fixedly provided on the magnetic ring. The telescopic coupling passes through the end of the main control sleeve and is fixedly installed with the axial sleeve. An axial electromagnet is also fixedly provided inside the main control sleeve. When the axial electromagnet is energized, it can magnetically attract the magnetic ring, thereby attracting the axial sleeve to move axially toward the main control sleeve against the elastic force of the axial spring.

[0012] The locking sleeve has a centering roller at its end and a lever locking plate inside. A fulcrum shaft is inserted through the lever locking plate and fixedly installed on the inner wall of the locking sleeve. The lever locking plate can swing around the fulcrum shaft. One end of the lever locking plate has a locking part and the other end has an expanding magnetic attraction part. A V-shaped spring is provided on the lever locking plate. The V-shaped spring applies elastic pressure to the lever locking plate, causing the locking part to tend to move away from the insulating outer skin. An expanding electromagnetic ring is fixedly installed inside the locking sleeve. When the expanding electromagnetic ring is energized, it generates magnetic force, attracting the expanding magnetic attraction part to expand outward. At this time, the lever locking plate swings around the fulcrum shaft, overcoming the elastic force of the V-shaped spring, so that the locking part contacts and locks with the insulating outer skin.

[0013] A manufacturing process for a high-strength medical cable with antibacterial function, comprising the following steps: Step 1: Embed the track control strip onto the surface of the insulating outer skin, so that the track control strip is laid along the length of the insulating outer skin, and the track control strip and the insulating outer skin are fixed together with glue; Step two, then put the antibacterial components onto the insulating outer sheath so that the antibacterial components make corresponding contact with the track electrical control strip.

[0014] Compared with the prior art, the beneficial effects of the present invention are: The medical cable of this invention, through the combination of a track electrical control strip, a main control sleeve, and an ultraviolet lamp, can comprehensively sterilize the surface of the insulation sheath during idle periods. Sterilization is carried out by irradiating the cable surface from the outside, which can effectively sterilize the side with contaminants attached to it, reducing cross-contamination when in contact with patients or medical staff.

[0015] This invention, through the coordinated arrangement of a piston-type contact, a push plate top shaft, and an air bladder, enables positive pressure gas to be ejected from the central air passage as the shaft sleeve moves toward the main control sleeve. This gas intervenes between the piston-type contact and the track electrical control bar, promptly blowing away dust and debris generated by frictional contact, thus making the power supply between the piston-type contact and the track electrical control bar more stable.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1 to 7 This invention provides a technical solution: a high-strength medical cable with antibacterial function, comprising an insulating outer sheath 1 and antibacterial components, such as... Figure 2 As shown, the inner surface of the insulating outer sheath 1 is provided with cable cores 101 and tensile steel ropes 102. Depending on the cable type, several cable cores 101 can be provided. This invention... Figure 2 The diagram shows four tensile steel ropes 102, which are made of steel wire and are inserted inside the insulating outer sheath 1. This effectively improves the strength of the medical cable of the present invention, making the cable more tensile-resistant.

[0026] The antibacterial components are fitted onto the outside of the insulating outer sheath 1, and the surface of the insulating outer sheath 1 is embedded with a track-controlled strip 2, such as... Figure 2 As shown, the surface of the insulating outer skin 1 has a track arc groove 103 along the length direction of the insulating outer skin 1. The bottom of the cross section of the track arc groove 103 is semi-arc-shaped. Through the arc structure design, the probability of the insulating outer skin 1 cracking from the track arc groove 103 is reduced. The track electrical control strip 2 is made of metal conductor and can bend with the insulating outer skin 1. The track electrical control strip 2 is laid inside the track arc groove 103 and fixed by adhesive. The track electrical control strip 2 provides power to the antibacterial group accessories.

[0027] The antibacterial assembly includes a main control sleeve 3 and a pivot sleeve 4. The pivot sleeve 4 can move axially back and forth relative to the main control sleeve 3. A locking sleeve 5 is fixedly installed on one end of the main control sleeve 3 and on the pivot sleeve 4. When the locking sleeve 5 is energized, it can lock relative to the insulating outer sheath 1. By the axial reciprocating movement of the pivot sleeve 4 relative to the main control sleeve 3, and in conjunction with the energization control of the locking sleeve 5, the antibacterial assembly can move axially along the outer surface of the insulating outer sheath 1. The end of the locking sleeve 5 is provided with a centering roller 501, such as Figure 3 As shown, several sets of centering rollers 501 are arranged in a circumferential array and are evenly distributed. The centering rollers 501 make the locking sleeve 5 roll contact with the insulating outer skin 1, which reduces friction and avoids damage to the outer surface of the insulating outer skin 1. The locking sleeve 5 is provided with a lever locking plate 502 inside, and a fulcrum shaft 503 is inserted in the lever locking plate 502. The fulcrum shaft 503 is fixedly installed on the inner wall of the locking sleeve 5. The lever locking plate 502 can swing with the fulcrum shaft 503 as the fulcrum. One end of the lever locking plate 502 is provided with a locking part 504, and the surface of the locking part 504 is provided with anti-slip horizontal grooves. The other end is provided with an expansion magnetic suction part 505. A V-shaped spring piece 506 is provided on the lever locking plate 502. The V-shaped spring piece 506 applies elastic pressure to the lever locking plate 502, so that the locking part 504 has a tendency to move away from the insulating outer skin 1. An expansion electromagnetic ring 507 is fixedly installed inside the locking sleeve 5. When the expansion electromagnetic ring 507 is energized, it can generate magnetic force, attracting the expansion magnetic part 505 to expand outward. At this time, the lever locking plate 502 swings around the fulcrum shaft 503, overcoming the elastic force of the V-shaped spring 506, so that the locking part 504 contacts and locks with the insulating outer skin 1.

[0028] The main control sleeve 3 is equipped with an ultraviolet lamp 6, which emits ultraviolet light to sterilize the surface of the insulating outer sheath 1. Figure 3 As shown, a lamp support plate 601 is integrally formed on the inner wall surface of the main control sleeve 3. The lamp support plate 601 is as follows: Figure 3 or Figure 6 As shown, the lamp support plate 601 is provided in several groups, which are evenly distributed in a circular array. The lamp support plate 601 supports the ultraviolet lamp 6 and can isolate, protect and buffer the ultraviolet lamp 6.

[0029] The inner wall of the main control sleeve 3 is fixedly installed with a partition inner ring 7 and a pneumatic inner ring 8, and the ultraviolet lamp tube 6 is installed between the partition inner ring 7 and the pneumatic inner ring 8.

[0030] A cylindrical groove 701 is provided on the inner ring 7, and a piston-type contact 702 is provided in the cylindrical groove 701. The piston-type contact 702 is in airtight contact with the inner wall surface of the cylindrical groove 701. The piston-type contact 702 is in sliding conductive contact with the track electrical control bar 2. A central air passage 703 is provided through the piston-type contact 702. A connecting spring 704 is provided inside the cylindrical groove 701. The connecting spring 704 applies elastic pressure to the piston-type contact 702, so that the piston-type contact 702 keeps in contact with the track electrical control bar 2. The connecting spring 704 is also used as a power supply conductor. The current of the track electrical control bar 2 reaches the connecting spring 704 through the piston-type contact 702. A wire is welded to the end of the connecting spring 704 to draw power.

[0031] The inner ring of the pneumatic inner ring 8 has an inner ring chamber 801 inside, and a compression push plate 802 is provided in the inner ring chamber 801. A push plate top shaft 803 is fixedly provided on the compression push plate 802. The push plate top shaft 803 passes through the side wall of the main body control sleeve 3 and extends out from the end of the main body control sleeve 3.

[0032] A positioning shaft 804 is fixedly installed inside the inner ring chamber 801. The positioning shaft 804 passes through the extrusion push plate 802 and limits the extrusion push plate 802. An air inlet groove 805 is opened through the side wall of the inner ring chamber 801 to the outside.

[0033] An airbag section 806 is provided inside the inner ring chamber 801. When the axial sleeve 4 moves axially toward the main control sleeve 3, the axial sleeve 4 will press against the push plate top shaft 803. The push plate top shaft 803 drives the compression push plate 802 to move, so that the compression push plate 802 compresses the airbag section 806. An air inlet channel 807 and an exhaust channel 808 are also provided in the pneumatic inner ring 8. One end of the air inlet channel 807 is connected to the airbag section 806, and the other end is connected to the inner cavity of the inner ring chamber 801. One end of the exhaust channel 808 is connected to the airbag section 806, and the other end is connected to an external connecting pipe 811, and is connected to the cylindrical groove 701 through the external connecting pipe 811.

[0034] A first one-way valve 809 is provided in the air intake channel 807, and a second one-way valve 810 is provided in the exhaust channel 808. The first one-way valve 809 causes the gas in the air intake channel 807 to flow unidirectionally toward the airbag part 806, and the second one-way valve 810 causes the gas in the airbag part 806 to flow unidirectionally toward the exhaust channel 808.

[0035] An axial spring 401 is provided between the main control sleeve 3 and the shaft sleeve 4. A magnetic ring 402 is provided inside the main control sleeve 3. A telescopic coupling 403 is fixedly provided on the magnetic ring 402. The telescopic coupling 403 is limited to passing through the end of the main control sleeve 3 and is fixedly installed with the shaft sleeve 4. The main control sleeve 3 is also fixedly equipped with a shaft-moving electromagnet 404. When the shaft-moving electromagnet 404 is energized, it can magnetically cooperate with the magnetic ring 402, thereby attracting the shaft-moving sleeve 4 to overcome the elastic force of the axial spring 401 and move axially toward the main control sleeve 3.

[0036] A manufacturing process for a high-strength medical cable with antibacterial function, comprising the following steps: Step 1: Embed the track control strip 2 onto the surface of the insulating outer skin 1, so that the track control strip 2 is laid along the length of the insulating outer skin 1, and the track control strip 2 and the insulating outer skin 1 are fixed together with glue; Step two, then put the antibacterial components onto the insulating outer skin 1, so that the antibacterial components make corresponding contact with the track electrical control strip 2.

[0037] When the medical cable of the present invention is used, the track electrical control strip 2 is connected to the external control circuit through both ends of the cable, so that the track electrical control strip 2 can supply power to the antibacterial group accessories. Since the track electrical control strip 2 is in an exposed state, the working voltage of the track electrical control strip 2 must be lower than the standard human safety voltage of 36V. It is preferred to use 5V voltage for power supply, which is far lower than the human safety voltage.

[0038] When the antibacterial components are fitted onto the outside of the insulating outer sheath 1, the piston-type contact 702 makes conductive contact with the track electrical control strip 2 to obtain electrical energy, such as... Figure 2 As shown, since the track groove 103 has a certain depth, when the piston contact 702 contacts the track electrical control bar 2, the track groove 103 will limit the piston contact 702 to prevent the antibacterial components from rotating and the piston contact 702 from being misaligned with the track electrical control bar 2.

[0039] The present invention also includes a control circuit board inside the main control sleeve 3, which is not shown in the figure of the prior art. The piston contact 702 first supplies power to the control circuit board through the connecting spring 704, and the control circuit board then controls the expanding electromagnetic ring 507, the shaft electromagnet 404 and the ultraviolet lamp 6.

[0040] When medical cables need to be sterilized during off-peak hours, Figure 3 As shown in the example, the expanding electromagnetic ring 507 in the locking sleeve 5 on the right side is first energized. The expanding electromagnetic ring 507 attracts the expanding magnetic suction part 505 to expand outward through magnetic force, causing the lever locking plate 502 to swing around the fulcrum axis 503. The locking part 504 contacts and locks with the outer surface of the insulating outer skin 1. At this time, the locking sleeve 5 on the right side is locked with the insulating outer skin 1; in conjunction with the reference Figure 4 Then, power is supplied to the axial electromagnet 404, which attracts the magnetic ring 402 to move to the right, causing the axial sleeve 4 to move towards the main control sleeve 3. At this time, since the locking sleeve 5 is locked with the insulating outer skin 1, the main control sleeve 3 will move a distance to the right relative to the insulating outer skin 1. Subsequently, the locking sleeve 5 on the left side locks with the insulating outer skin 1, and the locking sleeve 5 on the right side is released, disconnecting the power supply to the axial electromagnet 404. Under the elastic force of the axial spring 401, the axial sleeve 4 moves away from the main control sleeve 3. At this time, the main control sleeve 3 and the insulating outer skin 1 remain stationary, and the axial sleeve 4 moves a distance to the right, continuously cycling, so that the main control sleeve 3 can move axially along the surface of the insulating outer skin 1. The same applies when moving in the opposite direction.

[0041] During this period, the ultraviolet lamp 6 is powered and emits ultraviolet light to sterilize the surface of the insulation sheath 1. Sterilization is carried out from the outside towards the cable surface, which can effectively sterilize the side with contaminants attached to it and reduce cross-contamination when in contact with patients or medical staff.

[0042] During the above process, whenever the pivot sleeve 4 moves closer to the main control sleeve 3, such as Figure 5 and Figure 6As shown, the axial sleeve 4 axially compresses the push plate top shaft 803, causing the push plate top shaft 803 to move to the left, thereby driving the compression push plate 802 to move to the left. The compression push plate 802 compresses the airbag part 806, causing the gas in the airbag part 806 to enter the exhaust channel 808 through the second one-way valve 810, and finally enter the cylindrical groove 701 through the external connecting pipe 811, and be ejected through the central air passage 703; the central air passage 703 moves along the surface of the track electronic control bar 2, while the track electronic control bar 2... Because of its relatively long length and exposed installation, when the surface of the track electrical control bar 2 has a certain amount of dust, the dust will accumulate between the piston contact 702 and the track electrical control bar 2 as the central air passage 703 moves and scrapes, affecting the stability of the power supply contact. However, this invention sprays gas through the central air passage 703, and the gas enters between the piston contact 702 and the track electrical control bar 2, which can promptly blow away the powder and dust generated by friction contact, making the power supply contact between the piston contact 702 and the track electrical control bar 2 more stable.

[0043] When the pivot sleeve 4 moves away from the main control sleeve 3, the airbag part 806 extends under its own elastic force, and external gas is drawn into the airbag part 806 through the air intake channel 807 and the first one-way valve 809 to achieve cyclic replenishment.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
