Description

Technical Field

[0001] This utility model relates to the field of medical product technology, specifically to an operating room floor suction device. Background Technology

[0002] The utility model patent with publication number CN219803808U discloses an operating room nursing needle finder, which uses a strong magnetic rod to magnetically attract and find metal needles that have fallen in the operating room. Moreover, by setting up a rotating mechanism, the strong magnetic rod can search for needles by rotating in both directions, which greatly improves the searching range of the strong magnetic rod and makes the needle finding area of ​​the strong magnetic rod wider. This avoids the situation in the past where the use of a large magnetic plate made the whole device bulky and inflexible during operation.

[0003] While the utility model patent (CN219803808U) effectively expands the needle-finding range through the forward and reverse rotation design of a strong magnetic rod, solving the problems of bulky devices and inflexible operation caused by the use of large-area magnetic plates in traditional needle finders, this technical solution still has certain limitations in practical applications. Specifically, due to the strong magnetism of the magnetic rod, after attracting a metal needle, the magnetic force may make it difficult to remove the needle from the surface of the magnetic rod. In this case, medical staff need to overcome a large attraction force when retrieving the needle, which not only increases the difficulty and time cost of operation, but may also cause the needle to slip or be damaged due to improper force, and may even cause accidental injury to the medical staff. In addition, frequent needle retrieval operations may also cause wear on the surface of the magnetic rod, thereby affecting its attraction performance and service life. Therefore, the existing technology still needs further optimization in terms of magnetic control of the magnetic rod and the convenience of needle retrieval to better meet the needs of efficient, convenient and safe needle finding in operating room nursing. Utility Model Content

[0004] This invention proposes a needle suction device for operating room floors, which solves the problem that in the prior art, the strong magnet of the magnetic rod makes it difficult to remove the needle from the surface of the magnetic rod after it has attracted the metal needle.

[0005] The technical solution of this utility model is implemented as follows:

[0006] An operating room floor suction device includes a handrail and a chassis at its bottom, with an electromagnet rotatably connected to the bottom of the chassis; a collection component located at the bottom of the electromagnet is fixedly connected to one side of the bottom of the chassis via a connecting block; the collection component includes a triangular strip with its long side close to the electromagnet, a collection cover is provided outside the triangular strip, the top of the collection cover is open and communicates with the outside and surrounds the triangular strip; the inclined surface of the triangular strip and the open side of the collection cover form a feed inlet.

[0007] Furthermore, the inside of the collection cover is provided with an anti-detachment strip, and the inside of the triangular strip is provided with an anti-detachment groove, and the anti-detachment strip is slidably connected along the anti-detachment groove.

[0008] Furthermore, the collection cover is provided with a first sealing cover at the center of the circle away from the magnetic disk; the triangular strip is provided with a second side cover at the center of the circle near the magnetic disk, and the shape of the first sealing cover and the second side cover is the cross-sectional shape of the collection cover.

[0009] Furthermore, the top of the chassis is provided with a boss, and the inside of the boss is provided with a stepped hole, in which a stepped shock absorber seat is adapted.

[0010] Furthermore, a motor is provided on the stepped shock absorber base, and the output shaft of the motor passes through the stepped shock absorber base and the chassis and is connected and fixed to the top of the electric disk.

[0011] Furthermore, the external thread of the boss is connected to a shock-absorbing housing located outside the stepped shock-absorbing seat, and the upper part of the shock-absorbing housing is connected to a motor housing located outside the motor.

[0012] Furthermore, a hinge support is provided above the motor housing, and the lower part of the handrail is rotatably connected to the hinge support via a rotating shaft.

[0013] Furthermore, the chassis is equipped with multiple ball bearings near its edge to roll with the ground.

[0014] The beneficial effects of the technical solution provided in this application are as follows:

[0015] This operating room floor needle suction device uses the magnetic switching of an electromagnet to prevent needles from being permanently attracted. Its rotational function allows the attracted needles to slide along the inclined surface of the triangular strip into the inlet and eventually fall into the collection hood. This process not only achieves rapid and convenient needle collection but also avoids the time-consuming, labor-intensive, and potentially safe risks associated with manual needle removal.

[0025] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Reference Figure 1-4 A needle suction device for operating room floors includes a handle 10 and a base 20 at its bottom, with an electromagnet 30 rotatably connected to the bottom of the base 20. The device is characterized in that a collection component 40 located at the bottom of the electromagnet 30 is fixedly connected to one side of the bottom of the base 20 via a connecting block 41. The collection component 40 includes a triangular strip 42 with its long side close to the electromagnet 30, and a collection cover 43 is provided outside the triangular strip 42. The upper part of the collection cover 43 is open and communicates with the outside, surrounding the triangular strip 42. The inclined surface of the triangular strip 42 and the open side of the collection cover 43 form an inlet 44. The electromagnet 30, through its magnetic on / off control, can not only attract metal needles but also release them when needed, avoiding difficulties in needle retrieval due to excessive magnetic force. Furthermore, the rotation function of the electromagnet 30 further facilitates the movement of the attracted needle along the inclined surface of the triangular strip 42 to the inlet 44, and finally into the collection cover 43. This continuous action design greatly improves the efficiency and convenience of needle collection.

[0027] When the electromagnet 30 is energized and becomes magnetic, it can attract metal needles from the ground. By controlling the on / off state of the current, the magnetism of the electromagnet 30 can be controlled, thus releasing the needle when needed. The rotation of the electromagnet 30 is achieved through the rotational connection of the chassis 20. This design allows the needles attracted to the electromagnet 30 to move on the inclined surface of the triangular bar 42. The inclined surface design of the triangular bar 42 and the open setting of the collection cover 43 together form an effective collection system, enabling the needles to be smoothly transferred from the electromagnet 30 to the collection cover 43, achieving fast and safe collection of needles, reducing the operational difficulty and time cost for medical personnel, and avoiding needle damage or accidental injury that may be caused by improper operation.

[0028] In some embodiments, the collection cover 43 has an anti-detachment strip 45 inside, and the triangular strip 42 has an anti-detachment groove 46 inside. The anti-detachment strip 45 slides along the anti-detachment groove 46. The cooperation function of the anti-detachment strip 45 and the anti-detachment groove 46 is mainly to achieve quick and stable installation between the collection cover 43 and the triangular strip 42. This design allows the collection cover 43 to be installed and removed from the triangular strip 42 by plugging and unplugging, thereby facilitating the cleaning or replacement of the collection cover without the need for complex disassembly of the entire suction device. The anti-detachment strip 45 slides along the anti-detachment groove 46 inside the triangular strip 42. When the collection cover 43 needs to be installed on the triangular strip, the anti-detachment strip 45 can slide along the anti-detachment groove 46 to a locking position, thereby fixing the collection cover 43 and preventing it from accidentally falling off during use. When it is necessary to remove the collection cover 43, the anti-detachment strip 45 can slide along the anti-detachment groove 46 to a release position, allowing the collection cover 43 to be easily removed from the triangular strip 42.

[0029] In some embodiments, the collection cover 43 has a first sealing cap 47 located away from the center of the magnetic disk 30; the triangular strip 42 has a second side cap 48 located near the center of the magnetic disk 30. The shapes of the first sealing cap 47 and the second side cap 48 are the cross-sectional shapes of the collection cover 43. When the collection cover 43 is installed on the triangular strip 42, these two caps close the collection cover from both ends, ensuring that the needles inside the collection cover will not fall out through the ends. Because the shapes of the first sealing cap 47 and the second side cap 48 match the cross-sectional shape of the collection cover 43, they can tightly seal the openings at both ends of the collection cover, thereby forming a closed collection environment.

[0030] In some embodiments, the top of the chassis 20 is provided with a boss 21, and the interior of the boss 21 is provided with a stepped hole 22, in which a stepped shock-absorbing seat 23 is adapted. A motor 50 is mounted on the stepped shock-absorbing seat 23, and the output shaft of the motor 50 passes through the stepped shock-absorbing seat 23 and the chassis 20, and is connected and fixed to the top of the electromagnet 30. The design of the boss 21 and the stepped hole 22 on the top of the chassis 20, as well as the use of the stepped shock-absorbing seat 23, primarily serves to provide a stable mounting platform for the motor 50 and to provide shock absorption during motor operation. The main function of the motor 50 is to provide rotational kinetic energy to the electromagnet 30, enabling the electromagnet to rotate. Then, through the inclined design of the triangular bar 42, the needles adsorbed at the bottom of the electromagnet are smoothly guided to fall into the collection cover 43.

[0031] In some embodiments, the external thread of the boss 21 is connected to a shock-absorbing housing 24 located outside the stepped shock-absorbing base 23, and the upper thread of the shock-absorbing housing 24 is connected to a motor housing 25 located outside the motor 50. The shock-absorbing housing 24 and the motor housing 25 are designed to provide additional protection and fixation for the stepped shock-absorbing base 23 and the motor 50. The shock-absorbing housing 24 can reduce the impact of external shocks and vibrations on the stepped shock-absorbing base 23, thereby protecting the motor 50 from direct physical damage. The motor housing 25 provides a more stable installation environment for the motor 50, helping to reduce noise and vibration generated during motor operation, while also protecting the motor from dust and moisture corrosion.

[0032] In some embodiments, a hinge support 26 is provided above the motor housing 25, and the lower part of the handrail 10 is rotatably connected to the hinge support 26 via a rotating shaft 27. The hinge support 26 is fixed above the motor housing 25, providing a stable rotation point for the handrail 10. The lower part of the handrail 10 is connected to the hinge support 26 via the rotating shaft 27, allowing the handrail 10 to rotate around the rotating shaft 27. This design allows the operator to adjust the angle of the handrail 10 as needed to achieve a more ergonomic operating posture. At the same time, the structural design of the hinge support 26 and the rotating shaft 27 helps to distribute the pressure of the handrail 10 on the motor housing 25, reducing the potential impact on the motor 50 and the magnetic disk 30, thereby ensuring the stability and durability of the entire needle suction device during operation.

[0033] In some embodiments, the chassis 20 is equipped with multiple ball bearings 28 near its edge, which roll along the ground. The ball bearings 28 are mounted on the edge of the chassis 20 and directly contact the ground. When the operator pushes or pulls the handle 10, the ball bearings 28 roll on the ground, moving the entire suction device accordingly. Because the rolling friction of the ball bearings 28 is much less than the sliding friction, the force required to move the suction device is significantly reduced, making the device easier to operate. Furthermore, the design of the ball bearings 28 also helps reduce wear and tear on the floor, protecting the operating room floor materials.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
