Detailed Description

The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

The inventors of the present application have studied and found that hose holders find many applications in many fields, such as the field of medical devices. In particular applications, the hose support may be used to carry items. At present, after a period of bearing use, most hose supports have the condition that the bearing performance of the hose supports is greatly reduced, so that the stability of the hose supports is reduced, and the service life of the hose supports is further reduced. In order to solve the above-described problems, the present application proposes the following embodiments.

The following is an exemplary description of a stent assembly according to a stent assembly embodiment of the present application.

Fig. 1 illustrates a perspective structure of the bracket assembly 10, and fig. 2 illustrates an exploded structure of the bracket assembly 10. As shown in fig. 1 and 2, the stent assembly 10 may include a tubular stent 100 and a support 200. Optionally, the stent assembly 10 may further include a first elastic sheath 300 and a second elastic sheath 400.

The tubular stent 100 is flexibly and flexibly arranged, and the supporting member 200 is disposed in the tubular stent 100 and is used for supporting the tubular stent 100 when the tubular stent 100 is in a bent configuration. The first elastic sheath 300 may be wrapped around the outer circumference of the tubular stent 100 for wrapping the flexibly bent portion of the tubular stent 100. The second elastic sheath 400 may be sleeved on the outer circumference of the tubular stent 100, and may be coated on the outer circumference of the first elastic sheath 300.

Figure 3 illustrates a schematic cross-sectional view of the bracket assembly along section line A-A. As shown in fig. 2 and 3, the tubular stand 100 is a main body for supporting an object. The tubular stent 100 may exhibit a flexible bending by an external force, wherein the flexible bending means that the tubular stent 100 may be bent and deformed to exhibit a bent state by the external force, and the tubular stent 100 may remain in the bent state without being restored after the external force is removed. And the tubular stent 100 still has a certain bearing capacity in a bent state to support other objects.

Wherein the tubular stent 100 is provided with a receiving channel 110 for receiving the supporting member 200 in an extending direction, which is indicated by a B arrow shown in fig. 2.

Alternatively, the tubular stent 100 may include a flexible tube 120, and the receiving channel 110 is formed on the flexible tube 120 and penetrates through both ends of the flexible tube 120. The flexible tube 120 can be flexibly bent by external force, and still has a certain bearing capacity in the bent state, so that the tubular support 100 can be flexibly bent and support other objects.

Optionally, tubular stent 100 may further comprise connecting tube 130 and securing tube 140. One end of the connecting tube 130 is sleeved at one end of the flexible tube 120, and the other end of the connecting tube 130 extends away from the flexible tube 120 along the extending direction. One end of the fixing tube 140 is sleeved on the other end of the flexible tube 120 far from the connecting tube 130, and the other end of the connecting tube 130 extends far from the flexible tube 120 along the extending direction.

Further, the flexible pipe 120 may include a main pipe section 121 and receiving pipe sections 122 connected to both ends of the main pipe section 121. The main body pipe section 121 has a flexible bending property, and has a certain supporting force when being bent by an external force. The receiving pipe sections 122 at both ends are for receiving the main pipe section 121. In one embodiment, the outer diameter of the receiving tube section 122 is smaller than the outer diameter of the main tube section 121, which may facilitate the mounting and securing of the main tube section 121 by the receiving tube sections 122 at both ends, and may also enhance the load carrying capacity of the main tube section 121 in the bent configuration.

Wherein the receiving channel 110 may extend through the main body pipe section 121 and each receiving pipe section 122, and further extend through both ends of the flexible pipe 120, so as to facilitate assembling the support 200 when assembling the bracket assembly 10 and replacing the support 200.

Alternatively, the outer circumference of the flexible tube 120 is provided with a spiral groove 123 extending spirally in the extending direction. Specifically, the spiral groove 123 is mainly provided at the outer circumference of the main body pipe section 121, so that the main body pipe section 121 is more easily bent when an external force is applied.

Optionally, the connecting tube 130 and the fixing tube 140 are respectively sleeved on the receiving tube sections 122 at two ends of the flexible tube 120, so that the bracket assembly 10 is convenient to be mounted and fixed on other objects or machines, so that the bracket assembly 10 is more stable in use, and the use experience of the bracket assembly 10 is improved.

As shown in fig. 3, one end of the connecting tube 130 has a first insertion slot 131, a receiving tube 122 is inserted and fixed in the first insertion slot 131, and an end face of one end of the connecting tube 130 abuts against an end face of one end of the main tube 121. One end of the fixed pipe 140 is provided with a second inserting slot 141, the other receiving pipe section 122 is inserted and fixed in the second inserting slot 141, and the end face of one end of the fixed pipe 140 is abutted against the end face of the other end of the main pipe section 121. By the arrangement, the connection structure of the flexible tube 120, the connecting tube 130 and the fixing tube 140 is more compact, so that the falling-off condition of the connecting tube 130 and the fixing tube 140 is reduced, and the stability of the bracket assembly 10 is improved.

Wherein, the receiving channel 110 communicates with the first receiving slot 131 and the second receiving slot 141, so that the gas of the first receiving slot 131 and the second receiving slot 141 can enter the receiving channel 110.

Further, the connecting tube 130 may be provided with a first channel 132 extending along the extending direction, and has a plurality of first ventilation holes 133 communicating with the outside. The first ventilation holes 133 are respectively disposed on an end surface and/or an outer periphery of the other end of the connecting tube 130, and are in communication with the first channel 132. Wherein the first passage 132 communicates with the first socket 131, and thus, the receiving passage 110 may communicate with the first passage 132 by communicating with the first socket 131, and further communicate with the external atmosphere through the plurality of first vent holes 133.

Alternatively, the fixing tube 140 may be provided with a second channel 142 extending along the extending direction, and has at least one second vent hole 143 communicating with the outside, where the second vent hole 143 communicates with the first channel 132. The second passage 142 communicates with the second receiving slot 141, and thus, the receiving passage 110 may communicate with the second passage 142 by communicating with the second receiving slot 141, and thus communicate with the external atmosphere through the second vent hole 143.

As shown in fig. 2 and 3, the support 200 may be disposed in the receiving channel 110 along a predetermined extension direction. Alternatively, the support 200 is an elastic support for elastically supporting the tubular stent 100 when the tubular stent 100 is in the bent configuration. Specifically, the supporting member 200 has a certain elastic restoring force after being deformed along with the bending of the tubular support 100, and the elastic restoring force can support the tubular support 100 in the bending state, but does not restore the tubular support 100, so as to further enhance the capability of the tubular support 100 to bear and support other objects in the bending state, and meanwhile, the supporting member 200 can share the pressure from the supported objects received by the tubular support 100, so as to improve the bearing capacity and stability of the overall tubular support 100, thereby improving the service life of the support assembly 10.

For example, the support 200 includes at least one of PU elastic bars, aluminum bars, and springs. The PU spring bars, aluminum strips or springs (spring steel wires) have strong elasticity and load bearing properties, and can well support the tubular stent 100 to improve the load bearing capacity of the overall stent assembly 10. In addition, the number of the supporting members 200 may be plural, and the plurality of supporting members 200 may have stronger elasticity and bearing capacity to support the tubular stent 100.

In particular, the support 200 may be used to support the flexible tube 120 when the flexible tube 120 is in a curved configuration. When the flexible tube 120 is forced to bend, the support 200 may follow the bending of the flexible tube 120 and provide a supporting force to the flexible tube 120, thereby sharing the pressure of the supported object to which the flexible tube 120 is subjected. Wherein, the extension length of the supporting member 200 is less than or equal to the extension length of the flexible tube 120, so as to save the product cost of the tubular stand 100, and the flexible tube 120 can be better supported by being better bent along with the flexible tube 120.

As shown in fig. 3 and 4, fig. 4 is an enlarged schematic view of a partial area I of the stent assembly shown in fig. 3, wherein the first elastic sheath 300 is wrapped around the outer periphery of the flexible tube 120, and the second elastic sheath 400 is also wrapped around the outer periphery of the flexible tube 120 and wrapped around the outer periphery of the first elastic sheath 300.

The first elastic sheath 300 and the second elastic sheath 400 may be made of silica gel, polyurethane or other materials with wear-resistant and elastic properties, wherein the elastic properties may facilitate the assembly of the first elastic sheath 300 and the second elastic sheath 400, so as to improve the production efficiency. The abrasion resistance can reduce frictional noise generated when the flexible tube 120 is bent and increase the feel of the grip of the tubular stent 100.

In one embodiment, the first elastic sheath 300 is wrapped around the outer circumference of the main pipe section 121 to cover and fit the spiral groove 123 of the outer circumference of the main pipe section 121, so as to reduce friction sound generated by collision of the spiral grooves 123 when the flexible pipe 120 is bent, and prevent powder fragments generated by collision of the spiral grooves 123 from falling.

The first elastic sheath 300 is disposed between the fixing tube 140 and the connecting tube 130 to wrap the main tube 121 of the flexible tube 120, which can reduce the cost, and make the first elastic sheath 300 easy to be directly replaced after being damaged, without disassembling the connecting tube 130 and the fixing tube 140.

Further, the flexible tube 120 is provided with an air hole 124 communicating with the accommodating passage 110, so that the air in the accommodating passage 110 can be transferred to the flexible tube 120 through the air hole 124. The first elastic sheath 300 covers the air hole 124 when covering the flexible tube 120, and the air in the accommodating channel 110 can be transmitted into the gap between the flexible tube 120 and the first elastic sheath 300 through the air hole 124.

Optionally, the gas holes 124 communicate with the helical groove 123 and the receiving channel 110, such that the gas in the receiving channel 110 can be transferred through the gas holes 124 to the helical groove 123 and thus to the entire body of the flexible pipe 120. The first elastic sheath 300 wraps the spiral groove 123, and has a ventilation gap with the spiral groove 123, and the gas in the accommodating channel 110 can be transmitted into the ventilation gap through the gas hole 124, so as to be further transmitted into the gap between the flexible tube 120 and the first elastic sheath 300.

Specifically, there is also a gap between the support 200 in the accommodation channel 110 and the bracket of the flexible tube 120 so that when the both ends of the flexible tube 120 are ventilated into the accommodation channel 110, gas can flow in the gap between the support 200 and the flexible tube 120 so that the gas can be transferred to the spiral groove 123 of the outer circumference of the flexible tube 120 through the air holes 124 of the flexible tube 120.

Alternatively, when the first elastic sheath 300 is assembled, gas may be applied into the accommodating duct 110 at both ends of the flexible tube 120 such that the gas may fill the accommodating duct 110 and form a gas flow, and the gas in the accommodating duct 110 is further transferred to the outer circumference of the flexible tube 120 through the gas holes 124 such that the flexible tube 120 is entirely filled with the gas flow transferred from the accommodating duct 110 to the outer circumference of the body pipe section 121. At this time, the first elastic sheath 300 may be sleeved on a receiving tube section 122 of the flexible tube 120 and further pulled toward the main tube section 121, so that the air flow output from the accommodating channel 110 may enter the ventilation gap between the spiral groove 123 and the first elastic sheath 300, thereby blowing the first elastic sheath 300. The blown first elastic sheath 300 may be pulled further in the direction of the body tube segment 121, thereby wrapping the entire body tube segment 121. At this time, the application of gas to the receiving channel 110 of the flexible tube 120 is stopped, so that the first elastic sheath 300 is retracted, and the flexible tube 120 is wrapped and attached.

In other embodiments, after the connecting tube 130 and the fixing tube 140 are assembled, the gas may be applied to the second vent hole 143 of the fixing tube 140 so that the gas may sequentially pass through the second channel 142 and the second socket 141 to the receiving channel 110, and then be transferred to the whole body of the flexible tube 120 through the vent hole 124. While the gas may further reach the first socket 131, the first channel 132 of the connection pipe 130, and the first vent hole 133 located at the end surface or the outer circumference of the connection pipe 130. At this time, the first elastic sheath 300 may be sleeved at the other end of the connecting tube 130 away from the flexible tube 120, and the gas output from the first vent hole 133 may blow the first elastic sheath 300, so that the first elastic sheath 300 is easily pulled to the main body tube section 121 of the flexible tube 120. When the first elastic sheath 300 is pulled to the main body pipe section 121 of the flexible pipe 120, the airflow around the outer periphery of the main body pipe section 121 can further blow the first elastic sheath 300, so that the first elastic sheath 300 is easy to pull towards the main body pipe section 121 to wrap the whole main body pipe section 121, and at this time, the application of the air into the accommodating channel 110 of the flexible pipe 120 is stopped, so that the first elastic sheath 300 is retracted to wrap the flexible pipe 120.

As can be seen from the above description, the ventilation arrangement of the flexible tube 120 and the arrangement of the connecting tube 130 and the fixing tube 140 communicating the accommodating channel 110 with the outside can simplify the assembly process of the first elastic sheath 300 to increase the production efficiency of the bracket assembly 10.

Optionally, the second elastic sheath 400 further extends to cover at least a portion of the connecting tube 130 and at least a portion of the fixing tube 140, so that the second elastic sheath 400 further fixes the positions of the connecting tube 130 and the fixing tube 140, so that the connecting tube 130 and the fixing tube 140 are more tightly connected with the flexible tube 120, and are not easy to fall off from two ends of the flexible tube 120.

As shown in fig. 4, the connection pipe 130 has a joint pipe section 134 and a socket pipe section 135 connected to the joint pipe section 134. The connector section 135 is sleeved on one end of the flexible tube 120, and the connector section 134 is far from the flexible tube 120 compared with the connector section 135. Specifically, the second elastic sheath 400 further extends to cover the outer periphery of the connector tube section 135, and the first connector slot 131 is disposed in the connector tube section 135. The first channel 132 communicating with the first socket 131 is disposed in the joint pipe segment 134, and the plurality of first ventilation holes 133 are disposed at an end surface and/or an outer periphery of the joint pipe segment 134.

Wherein the outer diameter of the joint pipe section 134 is smaller than the outer diameter of the joint pipe section 135, and the joint pipe section 134 and the joint pipe section 135 form wedge-shaped inclined transition. The arrangement is such that when the second resilient sheath 400 is assembled, the second resilient sheath 400 can be moved toward the connector segment 135 through the wedge-shaped sloped transition region after being sleeved on the connector segment 134, thereby facilitating further movement to wrap the flexible tube 120, thereby completing the assembly.

In some embodiments, the stent assembly 10 described herein may be applied to a medical trolley. The structure of the medical trolley is exemplarily described below based on the contents of the above-described bracket assembly 10.

As shown in fig. 5, the medical trolley 1 may include a bracket assembly 10 and a trolley body 20, and the bracket assembly 10 may be fixedly provided to the trolley body 20.

In one embodiment, the trolley body 20 may include an operation table 21, the fixing tube 140 or the connecting tube 130 at one end of the bracket assembly 10 may be inserted into the operation table 21 and fixed, and the other end of the bracket assembly 10 may be mounted and connected with a detachable instrument, equipment, an appliance, an accessory or other medical apparatus, for example, a lead wire of an electrocardiograph, specifically, a connector for mounting an electrocardiograph lead wire branching mechanism (a non-cable portion) is mounted and connected at one end of the bracket assembly 10, and the electrocardiograph lead wire branching mechanism is mounted and connected on the connector, so as to realize support and azimuth adjustment of the electrocardiograph lead wire.

Of course, in other embodiments, one end of the bracket assembly 10 may be fixedly disposed on other components of the trolley body 20, such as a main body bracket for fixing the console 21.

In addition, the support assembly 10 with stronger supporting force is applied to the setting of the medical trolley 1, and the frequency of replacing the support assembly 10 by the medical trolley 1 can be reduced, so that the use efficiency of the medical trolley 1 is improved, and dust and fragments are not easy to generate to influence the operation effect on the operation table 21.

In summary, the support member 200 is disposed in the accommodating channel 110 of the tubular support 100, so that the tubular support 100 can be supported when the tubular support 100 is in a bent state, and then the support member 200 can provide a supporting force for the tubular support 100 when the support assembly 10 is in a working state for supporting other objects, so as to improve the bearing capacity and stability of the overall support assembly 10, and further increase the service life of the support assembly 10. Meanwhile, the first elastic sheath 300 and the second elastic sheath 400 are arranged on the periphery of the flexible tube 120 of the tubular support 100, so that friction sound generated when the tubular support 100 is bent is reduced, and dust generated by friction of the flexible tube 120 in the bending process can be prevented from falling.

The foregoing description is only exemplary embodiments of the present application and is not intended to limit the scope of the present application, and all equivalent structures or equivalent processes using the descriptions and the drawings of the present application, or direct or indirect application in other related technical fields are included in the scope of the present application.
