Description

Technical Field

[0001] This invention belongs to the field of medical and nursing technology, specifically relating to a massage and drainage device for preventing subcutaneous hematoma. Background Technology

[0002] After vascular puncture, the needle needs to be removed and pressure applied to the puncture site immediately to stop the bleeding. Currently, the common method is for the nurse to first apply pressure to the puncture site with a cotton swab, and then give the swab to the patient to apply pressure themselves. Because patients are often unable to perform the correct pressure application, subcutaneous bruising can easily occur at the puncture site, causing unnecessary pain.

[0003] For example, Chinese Patent Publication No. CN112120916B discloses a muscle massage device for preventing subcutaneous hematoma during hematological puncture. This device includes a guide sleeve, a support rod, a support guide frame, a base, and a muscle rotation massage mechanism. The support rod is fixed to one side of the upper part of the guide sleeve, the support guide frame is fixed to the other side of the upper part of the guide sleeve, and the base is fixed to the lower end of the support guide frame. This invention allows for intermittent adjustment of the pressure applied to stop bleeding, preventing subcutaneous hematoma accumulation, and also massages the area around the congestion point, thereby accelerating the dissipation of the congestion.

[0004] As described in the literature above, although the existing technology can massage the congested points after puncture, the massage area is limited, resulting in insufficient effect in dissipating blood stasis.

[0005] Practical content

[0006] The purpose of this invention is to provide a massage and drainage device for preventing subcutaneous hematoma, which can massage the skin around the puncture point over a wider area, thereby more effectively and significantly preventing the occurrence of subcutaneous hematoma.

[0007] The specific technical solution adopted in this utility model is as follows:

[0008] A massage and unblocking device for preventing subcutaneous hematoma includes a base mechanism, a massage mechanism disposed above the base mechanism, and a drive mechanism disposed on the top of the massage mechanism; the massage mechanism includes brackets movably disposed on both sides of the upper end of the base mechanism, a housing is disposed inside the brackets, a connecting rod is threaded through the inner side of the housing, and a massage head is installed below the connecting rod; the base mechanism includes a base plate, a lead screw is rotatably disposed inside the base plate, a connecting rod is threadedly engaged with the lead screw, and the two ends of the connecting rod are respectively connected to the bottom ends of the two brackets.

[0009] In a preferred embodiment, one end of the lead screw is connected to a drive motor.

[0010] In a preferred embodiment, each bracket has guide grooves at both ends, and guide blocks are slidably connected in the guide grooves. The guide blocks are fixedly connected to the outer shell. Each bracket has a locking rod threaded through its side, and the locking rod is threadedly engaged with the outer shell. The lower end of the outer shell has an arched structure.

[0011] In a preferred embodiment, a cavity is provided on the inner side of the outer shell, a heat conduction hole is provided through the bottom end of the cavity, and an electric auxiliary heating plate is provided inside the cavity.

[0012] In a preferred embodiment, the drive mechanism includes a cam disk rotatably mounted on the top of a housing, one end of which is connected to a drive motor, and the outermost part of the drive mechanism is an outer housing two mounted on the top of the housing.

[0013] In a preferred embodiment, the top end of the connecting rod is hinged to the cam disk, and the lower end of the connecting rod extends outward from the outer side of the housing.

[0014] The technical effects achieved by this utility model are as follows:

[0015] When this device is used to massage a patient, the rotation of the lead screw in the base mechanism drives the movement of the connecting rod, which in turn moves the massage mechanism on the base mechanism. This allows the massage head on the massage mechanism to change position relative to the patient's puncture point, enabling a larger area of ​​massage centered on the patient's puncture point. This more effectively and significantly prevents the occurrence of subcutaneous hematoma.

[0016] This utility model allows for height adjustment between the massage head on the outer shell and the base mechanism by adjusting the vertical movement between the outer shell and the support, thereby adjusting the intensity of the massage at the patient's puncture point placed on the base mechanism.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of this utility model. However, this utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of this utility model. The phrase "in a preferred embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0026] Secondly, this utility model is described in detail with reference to the schematic diagrams. When detailing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0027] Please see the appendix Figure 1 and Figure 2 As shown, this utility model provides a massage and unblocking device for preventing subcutaneous hematoma, including a base mechanism 1, a massage mechanism 2 disposed above the base mechanism 1, a drive mechanism 3 disposed on the top of the massage mechanism 2, and the massage mechanism 2 and the drive mechanism 3 are connected; the massage mechanism 2 includes a bracket 21 slidably connected to both sides of the upper end of the base mechanism 1, a housing 22 slidably connected to the inner side of the bracket 21, a connecting rod 26 slidably connected to the inner side of the housing 22, and a massage head 27 fixed below the connecting rod 26; the base mechanism 1 includes a base plate 11, a lead screw 12 rotatably disposed inside the base plate 11, a connecting rod 13 threadedly engaged on the lead screw 12, and the two ends of the connecting rod 13 are respectively fixedly connected to the bottom ends of the two brackets 21;

[0028] In this embodiment, when massaging around the puncture point, the patient's affected arm with the puncture site is first placed on the base plate 11 of the base mechanism 1. The drive mechanism 3 drives the connecting rod 26 in the massage mechanism 2 to move up and down. The up and down movement of the connecting rod 26 drives the massage head 27 to move up and down. The up and down movement of the massage head 27 can hammer the patient's affected arm to achieve a massage effect. During the massage, the rotation of the lead screw 12 in the base mechanism 1 can drive the massage head 27 on the massage mechanism 2 to move, so that the massage head 27 can be adjusted along the patient's affected arm, allowing the massage head 27 to hammer along the patient's affected arm, making the massage range larger and producing a better effect.

[0029] This application utilizes the rotation of the lead screw 12 in the base mechanism 1 to drive the movement of the connecting rod 13. The connecting rod 13 then drives the massage mechanism 2 to move on the base mechanism 1, thereby allowing the massage head 27 on the massage mechanism 2 to change position relative to the patient's puncture point. This allows for a larger area of ​​massage centered on the patient's puncture point, thus more effectively and significantly preventing subcutaneous hematoma.

[0030] One end of the lead screw 12 is connected to a drive motor 14;

[0031] In this embodiment, the rotation of the lead screw 12 is driven by a drive motor 14. The drive motor 14 can drive the lead screw 12 to rotate forward or backward within the base plate 11. Through the forward and reverse rotation of the lead screw 12 and its threaded engagement with the connecting rod 13, the connecting rod 13 can be driven to move back and forth within the base plate 11. Through the movement of the connecting rod 13, the massage mechanism 2 and the drive mechanism 3 can be driven to move back and forth on the base plate 11, thereby massaging the patient's affected arm.

[0032] Please see Figure 3 and Figure 4 As shown, each bracket 21 has a guide groove 23 at both ends, the guide groove 23 is slidably connected to the guide block 24, and the guide block 24 is fixedly connected to the outer shell 22. Both sides of the outer shell 22 are threaded with locking rods 25, and the ends of the two locking rods 25 that are far apart from each other pass through the bracket 21. The cross-sectional shape of the outer shell 22 in the vertical direction is arched. The top end of the connecting rod 26 is hinged to the cam disk 31, and the lower end of the connecting rod 26 extends out of the lower end of the outer shell 22.

[0033] In this embodiment, the linkage 26 is driven to extend and retract vertically by the drive mechanism 3. The maximum vertical extension distance of the linkage 26 is limited and not easily changed. When massaging the patient, in order to allow the patient to feel different massage intensities, the adjusting housing 22 can be adjusted vertically along the support 21. When the housing 22 is adjusted upward, the distance between the massage head 27 and the patient increases, thereby reducing the massage intensity felt by the patient. When the housing 22 is adjusted downward, the distance between the massage head 27 and the patient decreases, thereby increasing the massage intensity felt by the patient. This changes the massage intensity on the patient's affected arm. When the housing 22 is adjusted vertically along the support 21, the guide block 24 moves along the guide groove 23, thereby increasing the stability of the housing 22 during vertical movement. After adjustment, the locking rod 25 can be tightened to lock the housing 22 and the support 21 to maintain the required massage intensity.

[0034] A cavity 221 is provided on the inner side of the outer shell 22, and a heat conduction hole 29 is provided through the bottom end of the cavity 221. An electric auxiliary heating plate 28 is provided inside the cavity 221.

[0035] When performing a hammer massage on the patient, heat can be generated by the electric auxiliary heating plate 28 in the cavity 221, and the heat can be conducted to the patient's skin through the heat conduction hole 29, thereby achieving a heat compress effect on the patient.

[0036] The drive mechanism 3 includes a cam disk 31 rotatably mounted on the top of the outer casing 22. One end of the cam disk 31 is connected to a drive motor 32, and the drive motor 32 is fixedly connected to the outer casing 22. The outermost part of the drive mechanism 3 is the outer casing 33 mounted on the top of the outer casing 22.

[0037] The drive motor 32 of the outer shell 33 in the drive mechanism 3 drives the rotation of the cam disk 31. Since the upper end of the connecting rod 26 is hinged to the cam disk 31, the rotation of the cam disk 31 can drive the connecting rod 26 to move up and down, thereby performing a hammering massage on the patient's affected arm.

[0038] Furthermore, a first control element (not shown in the figure) is mounted on the outer side of the base mechanism 1, and a second control element (not shown in the figure) is mounted on the outer side of the outer shell 22. The first control element and the drive motor 14 and the second control element and the drive motor 32 are electrically connected by wires. The opening and closing of the drive motor 14 and the drive motor 32 can be controlled by the first control element and the second control element, respectively.

[0039] The working principle of this utility model is as follows: When massaging around the puncture site, the patient's affected arm with the puncture site is first placed on the base plate 11 of the base mechanism 1. The drive mechanism 3 drives the connecting rod 26 in the massage mechanism 2 to move up and down. The up and down movement of the connecting rod 26 drives the massage head 27 to move up and down. The up and down movement of the massage head 27 can hammer the patient's affected arm to achieve a massage effect. During the massage, the rotation of the lead screw 12 in the base mechanism 1 can drive the massage head 27 on the massage mechanism 2 to move its position. This allows the massage head 27 to be adjusted along the patient's affected arm, enabling it to hammer along the affected arm and thus expanding the massage area and producing a better effect.

[0040] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
