Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of medical devices, and in particular to a therapeutic pen. BACKGROUND

[0002] The vibrator in the mechanical vibration therapeutic pen can generate physical kinetic energy of a specific frequency, and transmit the kinetic energy of vibration to the needle through the mounting seat at the front end of the pen shaft, so that the needle generates local physical kinetic energy. In the treatment of limb pain, the damaged part of the human body limb soft tissue (muscle, tendon, etc.) is acted on, and the lesion area is treated specifically and effectively to remove the lesion and relieve pain. In the prior art, the needle of the therapeutic pen, such as the mechanical vibration therapeutic pen, cannot observe whether the patient's lesion has effusion and bleeding during the treatment, and it is also impossible to know how much the effusion and bleeding are, which requires the doctor to rely on long-term accumulated experience or use other medical devices for further diagnosis. Not only does this increase the diagnosis and treatment time, but the accuracy is also difficult to guarantee, and repeated insertion and removal of the needle also increases the pain of the patient and prolongs the treatment time.

[0030] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of this disclosure.

[0031] like Figures 1 to 6 As shown, an embodiment of the first aspect of this disclosure provides a therapeutic pen, which includes: a pen barrel 300, one end of which is provided with a mounting base 320; a pen cap 100, which is detachably connected to the end of the pen barrel 300 near the mounting base 320, and the pen cap 100 is provided with an observation window 110; a needle 200, which has a built-in liquid cavity 250, and the needle 200 is provided with a needle tube 210, a connecting part 220, and a needle seat 230 in sequence along the liquid cavity 250, wherein the needle seat 230 is made of transparent material so that the liquid accumulation in the liquid cavity 250 in the needle seat 230 can be observed through the pen cap observation window 110, and the needle seat 230 is detachably connected to the mounting base 320.

[0032] According to the treatment pen of the embodiment of the present disclosure, the mounting seat 320 is arranged at one end of the pen barrel 300, the cap 100 is detachably connected to the end of the pen barrel 300 close to the mounting seat 320, the observation window 110 is arranged on the cap 100, the needle head 200 is internally provided with the liquid cavity 250, the needle head 200 is sequentially provided with the needle tube 210, the connecting part 220 and the needle head seat 230 along the liquid cavity 250, the needle head seat 230 is made of transparent material, so as to observe the liquid in the liquid cavity 250 in the needle head seat 230 through the observation window 110 of the cap 100, and the needle head seat 230 is detachably connected to the mounting seat 320 of the pen barrel 300. In the prior art, when a doctor uses the treatment pen to treat a patient, the doctor cannot directly observe whether there is effusion and bleeding or the amount of effusion and bleeding at the lesion site in time, and thus needs to use other medical devices to further diagnose, which wastes a lot of time, and repeated intervention diagnosis and treatment of the lesion site undoubtedly increases the trauma and the psychological burden of the patient. In the treatment pen of the present disclosure, the observation window 110 is arranged, and the needle head seat 230 is made of transparent material, so that the doctor can observe whether there is effusion and blood in the cavity of the needle head seat 230 through the observation window 110 of the cap 100 during treatment, and can also simply judge the amount of effusion, so as to facilitate the doctor to obtain real-time information feedback of the lesion during treatment, and the doctor does not need to use other medical devices to judge whether there is effusion and bleeding at the lesion, so that the treatment time is greatly reduced, and the trauma and the psychological burden of the patient are reduced to a certain extent.

[0033] In some embodiments of the present disclosure, the size of the needle head seat 230 can be designed to be larger than that of the needle head seat of the international standard syringe needle, so that the liquid cavity 250 can accommodate more effusion. The larger size of the needle head seat 230 is more conducive to the doctor to obtain real-time feedback of the lesion site during treatment, and the needle head seat 230 can accommodate more effusion if there is more effusion at the lesion site of the patient.

[0034] In some embodiments of the present disclosure, the outer wall of the needle head seat 230 is provided with the positioning ring 231 abutting against the outer edge of the needle head seat 310. It can be understood that the positioning ring 231 is arranged in a circular ring distribution on the outer edge of the needle head seat 230. During installation and use, when the needle head seat 230 is installed in the mounting seat 320 of the pen barrel 300, one end of the positioning ring 231 abuts against the edge of the needle head seat 310 of the pen barrel 300. When the needle head seat 230 needs to be removed, the positioning ring 231 can be directly used for disassembly, so that the needle head seat 230 can be pulled out more easily.

[0035] In some embodiments of the present disclosure, the connecting portion 220 is provided with reinforcing ribs 221, and the reinforcing ribs 221 are fixedly connected with the needle seat 230 to keep the connecting portion 220 and the needle seat 230 stable. The number of the reinforcing ribs 221 can be two or more. It can be understood that the reinforcing ribs 221 can improve the stability of the connection between the connecting portion 220 and the needle seat 230.

[0036] In some embodiments of the present disclosure, the reinforcing ribs 221 are provided with protruding ends to install the round tubular needle cover 260. The edges of the protruding convex corners of the reinforcing ribs 221 form a bayonet structure with one end protruding. The matching round tubular needle cover 260 is fitted on the needle, and the root of the needle cover 260 is clamped under the bayonet structure to form a protective sleeve that is adaptively installed. For example, as shown in Figure 5 and Figure 6 The reinforcing ribs 221 are provided with an end face perpendicular to the end face of the needle cover 260. Thus, the end faces of the reinforcing ribs 221 form a circular ring shape. When the needle cover 260 is fitted on the needle, the inner edge of the needle cover 260 is in contact with the circular ring-shaped face of the reinforcing ribs 221. Further force is applied, and the needle cover 260 is stopped by the arc-shaped outer edge of the needle seat 230 to form a protective sleeve for the needle tube 210. Of course, this embodiment is only an exemplary preferred example. The point of the protruding end of the reinforcing rib 221 can also be in contact with the inner cavity of the needle cover 260, which is not limited in the present disclosure.

[0037] In some embodiments of the present disclosure, the edge of the needle seat 230 away from the needle tube 210 is provided with openings 241. The openings 241 are arranged in pairs and are arranged on the bottom edge of the needle seat 230, that is, the tension slot. When the needle seat 230 is installed on the mounting seat 320 of the pen barrel 300, further force is applied, and the bottom edge of the needle seat 230 is slightly opened, so that the needle seat 230 is more tightly fixed on the mounting seat 320 of the pen barrel 300.

[0038] In some embodiments of the present disclosure, the openings 241 on the needle seat 230 extend to the positioning ring 231. That is, by arranging the openings 241 near the positioning ring 231, the bottom of the needle seat 230 has a larger deformable space, that is, the needle seat 230 has more contact area with the mounting seat 320. Thus, when a doctor performs a treatment operation on a patient, even if the doctor uses more force or the physical vibration of the mechanical vibration treatment pen is larger, the needle seat 230 will not shake after being installed on the mounting seat 320, so that a better treatment effect can be ensured.

[0039] In some embodiments of the present disclosure, the cross section of the needle seat 230 along the central axis is arc-shaped. By setting the needle seat 230 to be arc-shaped, the internal space of the needle seat 230 can be designed to be larger, which can accommodate more lesion fluid. In addition, due to the convex arc shape of the needle seat 230, similar to a convex mirror, the liquid in the liquid cavity 250 in the needle seat 230 can be more clearly displayed, that is, the operator during treatment can more easily observe the state of the internal cavity of the needle seat 230 through the observation window 110 on the pen cap 100.

[0040] In some embodiments of the present disclosure, the connecting portion 220 and the needle seat 230 are integrated, that is, the connecting portion 220 and the needle seat 230 are integrally formed. For example, the connecting portion 220 and the needle seat 230 can be made of transparent medical plastic. As a result of one-time molding, the connecting portion 220 and the needle seat 230 can be more firmly connected.

[0041] In some embodiments of the present disclosure, the end of the needle tube 210 away from the connecting portion 220 is sharp and beveled. By setting the needle tube 210 to be sharp and beveled, the patient's skin can be more easily pierced, and the lesion fluid can more easily flow into the liquid cavity 250 of the needle 200. Of course, other methods can achieve the same effect. For example, the tip of the needle tube 210 can be set to be a sharp solid shape, and a liquid-permeable hole can be formed near the tip of the needle tube 210. The same effect can be achieved, and the present disclosure does not make specific limitations here.

[0042] In some embodiments of the present disclosure, the inside of the pen barrel 300 is provided with a mounting seat 320. The mounting seat 320 is arranged at one end of the pen barrel 300. The mounting seat 320 is internally provided with a vibrator (not shown in the figure). The vibrator is mounted with a PCB control board (not shown in the figure). The vibrator and the PCB control board are electrically connected to make the vibrator produce physical vibration. The PCB control board is electrically connected to a power supply device (not shown in the figure). After being powered on, the vibrator generates physical kinetic energy of a specific frequency, and transmits the vibration kinetic energy to the needle 200 through the mounting seat 320, so that the needle 200 generates local micro-vibration. In the treatment of limb pain, the vibration treatment can act on the damaged part of the muscle / tendon of the human body, and can perform small-range targeted vibration treatment on the lesion area to remove the lesion and relieve pain.

[0043] It is to be noted that, in the present text, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can also include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by "comprises... a" does not, without more constraints, exclude the presence of additional identical elements in the process, method, article, or apparatus that comprises the element.

[0044] Various embodiments of the present disclosure are described in related manner, and the same or similar parts between various embodiments can be referred to each other, and each embodiment focuses on the difference from other embodiments.

[0045] The above description is merely preferred embodiments of the present disclosure, not intended to limit the protection scope of the present disclosure.
