Description

Technical Field

[0001] This utility model relates to a medical auxiliary device, specifically a medicated stick used to assist in the treatment of patients with neck, shoulder, back and leg pain. Background Technology

[0002] The stick-based meridian massage method is a traditional Chinese medicine external treatment method that combines herbal medicine, meridian theory, and massage. By rolling the stick on the skin, the stimulation of medicine and acupoints helps to unblock meridians, promote blood circulation, remove blood stasis, and lubricate joints, allowing stagnant blood to disperse outwards and qi and blood to flow smoothly, achieving the effect of "no pain when there is free flow."

[0003] Chinese patent application number 202121571858.5 discloses a method of using a medicine stick, in which medicine is placed in a medicine bag made of gauze or cotton cloth, the moistened medicine bag is wrapped around the medicine stick and fixed with a rope, and then the stick is rolled and massaged on the patient's affected area.

[0004] However, the method of fixing the medicine bag to the outside of the medicine stick has the following drawbacks: the medicine bag needs to be sewn and tied every time it is used, which is not only troublesome to operate, but also makes it difficult to ensure the uniform distribution of the medicine, and it is easy to feel uncomfortable when rolling and massaging the patient's affected area. Utility Model Content

[0005] The purpose of this invention is to provide a medicine stick that is easy to use and can improve the comfort of patients during use.

[0006] To achieve the above objectives, this utility model employs a medicine stick, comprising a stick body, an outer sleeve fixed to the outside of the stick body, and a receiving cavity formed between the outer sleeve and the stick body for accommodating a liquid storage cylinder. A locking block for limiting the axial position of the liquid storage cylinder is detachably fixed on the stick body. The liquid storage cylinder has an inner cavity for accommodating liquid medicine, and the liquid storage cylinder has an inlet and an outlet. A plug is provided at the inlet, and the outlet is opened on the circumferential side wall of the liquid storage cylinder. An annular groove is provided on the circumferential inner wall of the outer sleeve or the circumferential outer wall of the liquid storage cylinder, and the annular groove corresponds one-to-one with the outlet. A through hole is provided on the side wall of the outer sleeve. When the liquid storage cylinder is located in the receiving cavity, and both ends of the liquid storage cylinder are in contact with the locking block and the bottom of the outer sleeve, respectively, the outlet, the annular groove, and the through hole are connected.

[0007] When using this utility model's medicinal stick, place the liquid reservoir into the receiving cavity between the stick body and the outer sleeve, then lock the reservoir with the locking block, pour the medicinal liquid into the reservoir, and then directly perform the meridian massage method. This utility model's medicinal stick only requires the filling of the medicinal liquid during use. After use, all parts of the stick can be disinfected and cleaned. Compared to wrapping the stick with a medicine bag or gauze, assembly and fixation are more convenient, and it avoids unevenness in the part of the stick that contacts the body, ensuring patient comfort during use.

[0008] The device can have several outlet holes spaced in a straight line on one side of the reservoir. The reservoir is then placed horizontally into the receiving cavity with the outlet holes facing upwards to minimize medication loss. The diameters of the outlet holes and through holes should be adjusted according to the medication concentration, and should be as small as possible to reduce the flow rate. The outer sleeve of the rod can be made of medical-grade plastic or hospital-grade silicone to further improve patient comfort.

[0009] Preferably, the outer sleeve is fitted over the rod body, and the rod body has a limiting portion extending outward in a circumferential direction. The outer sleeve is confined between the limiting portion and the locking block. This configuration allows the rod body and the outer sleeve to be made of different materials, and also facilitates the sterilization of both, enabling reuse.

[0010] Preferably, a dynamic seal is formed between the outer sleeve and the rod body, and the locking block is threadedly fixed to the rod body. The locking block has several spherical protrusions on its end face facing the limiting part. This arrangement allows the outer sleeve and the rod body to slide against each other, preventing the rod from pulling on the patient's skin when moving back and forth, thus ensuring comfort during use of the medicinal stick. The dynamic seal can be achieved using bearings, oil seals, etc., and the locking block can have integrally formed spherical protrusions or rotatably fixed spherical objects such as steel balls.

[0011] Preferably, the liquid storage cylinder and the outer sleeve are provided with a matching positioning groove and a positioning protrusion extending into the positioning groove. The positioning groove and positioning protrusion are provided to prevent relative movement between the liquid storage cylinder and the outer sleeve, and at the same time to better ensure the communication between the liquid outlet and the through hole.

[0012] Preferably, the liquid storage cylinder is provided with a strip-shaped groove that communicates with the liquid outlet. A pull bar for blocking the liquid outlet is fitted inside the strip-shaped groove. The pull bar has a connecting hole that corresponds one-to-one with the liquid outlet. One end of the pull bar extends axially out of the liquid storage cylinder. A pull bar is provided as a liquid outlet switch to facilitate the assembly and use of the medicine stick of this invention.

[0013] Preferably, the liquid storage cylinder is provided with a first limiting block to restrict excessive movement of the pull bar, and a second limiting block is fixed on the pull bar. When the pull bar moves to make the second limiting block contact the liquid storage cylinder or the first limiting block, the liquid outlet is blocked or the two ends of the liquid outlet are connected through a connecting hole. This arrangement prevents excessive movement of the pull bar, ensures communication between the liquid outlet and the connecting hole, and guarantees that the liquid flow rate is neither too high nor too low.

[0014] This invention has the advantages of being easy to use and improving patient comfort. Attached Figure Description
