Description
Technical Field
[0001] The invention relates to a Mongolian medicine bloodletting device, belonging to the technical field of medical equipment. Background Art
[0002] Mongolian medicine bloodletting therapy is one of the drastic treatments in Mongolian medicine clinical external treatments. It has good therapeutic effects on various diseases caused by blood. It is guided by the basic theories of Mongolian medicine. According to different conditions, specific needles are used to puncture or scratch the superficial blood vessels in specific parts of the human body to release an appropriate amount of blood. By releasing bad blood, the meridians are opened and unblocked, the circulation of qi and blood is promoted, blood heat is cleared, and body elements are adjusted to improve the ability to resist diseases and eliminate evil. The methods of bloodletting are divided into venous bloodletting, tissue bloodletting, and acupuncture bloodletting. The bloodletting instrument is generally a special knife. Traditional bloodletting needles can be divided into three-edged bloodletting needles, axe-type bloodletting needles and spear-type bloodletting needles according to their shapes.
[0003] Traditional Mongolian bloodletting needles require extremely high skills from medical staff during the bloodletting operation. When medical staff give acupuncture to patients for the first time, they do not control the strength accurately, resulting in the needle being inserted too deep or too shallow, and the needle cannot be effectively inserted into the corresponding acupuncture point, so the desired therapeutic effect cannot be achieved; existing bloodletting needles usually adopt an integrated structure, the bloodletting needles are thin and small in size, and are not very convenient to hold; traditional Mongolian bloodletting needles have the risk of infection when used repeatedly, causing infection suppuration, ulceration, bleeding, etc., and in severe cases even endangering the patient's life. Summary of the invention
[0004] The purpose of the present invention is to provide a Mongolian medicine bloodletting device, which solves the problem that medical staff cannot accurately control the force and are inconvenient to hold when using bloodletting needles.
[0005] The technical solution adopted by the present invention is as follows: a Mongolian medicine bloodletting device, including a fixed cylinder, one end of the fixed cylinder is connected to a slidably positioned movable cylinder, the movable cylinder is fixedly connected to a positioning sleeve, the fixed cylinder, the movable cylinder and the positioning sleeve are all open structures at both ends, and the three are connected to form an integrated cavity structure.
[0006] A slidable pressing rod is installed inside the fixed cylinder, and a rotatable pressing sleeve is installed on the upper end of the pressing rod. The lower end of the pressing sleeve is fitted and sleeved with the fixed cylinder to enhance the stability of the pressing rod and realize the limiting of the pressing rod. A supporting plate is fixed in the fixed cylinder, and the supporting plate is located on the upper side of the lower end of the pressing rod. A pressing spring sleeved on the pressing rod is fixed on the upper end of the supporting plate. A blocking piece is fixed on the pressing rod at the upper end of the pressing spring, and an ejection spring is fixed on the lower end of the pressing rod. A needle seat rod is connected, and a movable limiting piece is fixed to the needle seat rod near the side end of the ejection spring. The limiting piece passes through the corresponding side end of the fixed cylinder and slightly extends out of the fixed cylinder to realize the positioning of the needle seat rod. A limiting ring fixed to the inner wall of the fixed cylinder is sleeved on the needle seat rod, and the limiting ring is located on the lower side of the limiting piece and is used for telescopic positioning of the ejection spring. A bloodletting needle is detachably fixed to the lower end of the needle seat rod, and the bloodletting needle is composed of a needle handle and a needle head fixedly connected, and the needle handle is detachably and fixedly connected to the needle seat rod.
[0007] The side end of the pressing sleeve is fixed with a connecting plate that fits and slides with the fixed cylinder, the center of the connecting plate corresponds to the center of the limiting piece, and the lower end of the connecting plate is provided with an installation groove, in which an elastic strip with an arc structure is fixed. When the pressing sleeve is pressed, the pressing spring and the ejection spring are compressed at the same time, and when the elastic strip moves to the position of the limiting piece, the elastic strip is deformed, squeezing the limiting piece to move into the fixed cylinder, and at the same time the ejection spring is retracted to realize the sliding positioning of the needle seat rod, thereby limiting the distance that the bloodletting needle extends out of the positioning sleeve, popping out the needle, and realizing the puncture operation. The pressing sleeve is released, the pressing spring is retracted, the pressing rod moves upward, driving the needle seat rod and the elastic strip to move upward, and when the limiting piece pops out of the fixed cylinder, it returns to its original state.
[0008] Furthermore, the positioning sleeve is a transparent structure, which is convenient for observing the contact position between the needle and the patient's skin and the bloodletting condition. The lower edge of the positioning sleeve is an elastic structure, which is convenient for better contact with the patient's skin and prevents the device from sliding after contacting the patient's skin.
[0009] Furthermore, the threaded structure of the fixed cylinder is engaged with a matching locking ring, and has a rotation direction opposite to that of the threaded structure of the movable cylinder. The side surface of the locking ring is an anti-slip structure, which is used to lock the movable cylinder after the movable cylinder adjusts its position to prevent it from rotating.
[0010] Furthermore, when the pressing spring and the ejection spring are in a free state, the distance from the bottom end of the pressing sleeve to the upper end surface of the fixed tube is the same as the distance from the lower end of the elastic strip to the center of the limiting member, so that when the pressing sleeve contacts the fixed tube, the elastic body can just compress the limiting member into the fixed tube.
[0011] Furthermore, the shape of the needle tip may be one of an axe-shaped structure, a triangular structure, and a spear-shaped structure.
[0012] The beneficial effects of the present invention are:
[0013] The present invention utilizes a limited pressing spring and a ejection spring. After the pressing sleeve compresses the two, the pressing sleeve passes through the elastic sheet at the same time, so that the elastic force of the ejection spring realizes the puncture operation. After the pressing sleeve is released, the pressing spring rebounds and extends out, driving the bloodletting needle to be pulled out of the puncture site. The elastic force of the spring is used to realize the puncture operation. The puncture speed and strength do not depend on the operator's personal experience and hand feel. The needle insertion depth is easy to control, and there will be no problem of too deep or too shallow insertion. The needle can effectively penetrate the corresponding acupuncture point, and the operation is simple, which can reduce the pain and improve the bloodletting efficiency.
[0014] The present invention can select different types of bloodletting needles according to different bloodletting positions, has strong targeting and good treatment effect, and the needle is disposable, thus avoiding the infection problem caused by repeated use of the needle.
[0015] The present invention can adjust the extended length of the bloodletting needle, and can appropriately adjust the extended length of the bloodletting needle according to different patients. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] A slidable pressing rod 4 is installed inside the fixed cylinder 1, and a rotatable pressing sleeve 6 is installed on the upper end of the pressing rod 4 through a rotating shaft 5. The lower end of the pressing sleeve 6 is fitted and sleeved with the fixed cylinder 1 to enhance the stability of the pressing rod 4 and realize the sliding limit of the pressing rod 4. A support plate 7 is welded and fixed in the fixed cylinder 1. The support plate 7 is sleeved on the upper side of the lower end of the pressing rod 4. A pressing spring 8 sleeved on the pressing rod 4 is fixed to the upper end of the support plate 7 through a spring mounting seat. A baffle 9 that fits the inner wall of the fixed cylinder 1 is welded and fixed to the pressing rod 4 at the upper end of the pressing spring 8. The support plate 7 and the baffle 9 ensure the stability of the sliding of the pressing rod 4. A ejection spring 10 is fixed to the lower end through a spring fixing seat, and the ejection spring 10 is fixedly connected to a needle seat rod 11 through a spring fixing seat. A movable limiting member 12 is fixed to the needle seat rod 11 near the side end of the ejection spring 10, and the limiting member 12 includes a limiting spring 13, and the limiting spring 13 is fixed in a blind hole 14 opened at the side end of the needle seat rod 11 through a spring fixing seat. The limiting spring 13 is fixedly connected to a limiting head 15 through a spring fixing seat. The limiting head 15 is a structure formed by welding a round tube and a sphere, and the round tube fits the inner wall of the blind hole 14, and the sphere passes through the round hole opened in the fixed cylinder 1 and slightly extends out of the side end of the fixed cylinder 1, so as to realize the needle seat rod 11. The limiting part 12 is fitted with the inner wall of the blind hole 14 so that the limiting part 12 can only slide along the blind hole 14, thereby improving the stability of the limiting part of the needle seat rod 11. At the same time, when the limiting head 15 moves downward with the needle seat rod 11 in the fixed cylinder 1, the needle seat rod 11 is limited. A limiting ring 16 welded and fixed to the inner wall of the fixed cylinder 1 is sleeved on the needle seat rod 11. The limiting ring 16 is located on the lower side of the limiting part 12 and is used for telescopic positioning of the ejection spring 10. A bloodletting needle 17 is detachably fixed at the lower end of the needle seat rod 11. The bloodletting needle 17 is composed of a needle handle 17-1 and a needle head 17-2 fixedly connected. A symmetrical positioning part 17-2 is welded and fixed to the needle handle 17-1. 3. A fixing hole 18 is provided at the center of the lower end surface of the needle seat rod 11, and positioning grooves 19 corresponding to the positioning piece 17-3 are provided on both sides of the fixing hole 18. Thread holes perpendicular to the positioning grooves 19 are provided on the needle seat rod 11 at both sides of the blind hole 14, and a round hole corresponding to the thread hole is provided on the needle handle 17-1. The positioning piece 17-3 of the needle handle 17-1 is inserted into the positioning groove 19, and a bolt 20 is passed through the round hole and meshed with the thread hole to realize the disassembly and assembly fixed connection with the needle seat rod 11. According to the requirements of Mongolian medicine for bloodletting at different positions of the human body, the shape of the needle head 17-2 can be one of an axe-shaped structure 25, a triangular structure 26, and a spear-shaped structure 27.
[0025] The side end of the pressing sleeve 6 is welded with a connecting plate 21 that fits and slides with the fixed cylinder 1, and the center of the connecting plate 21 corresponds to the center of the limiting member 12. A mounting groove 22 is opened at the lower end of the connecting plate 21, and an elastic strip 23 with an arc structure is welded and fixed in the mounting groove 22. When the pressing sleeve 6 is pressed, the pressing spring 8 and the ejection spring 10 are compressed at the same time. When the elastic strip 23 moves to the position of the limiting member 12, the elastic strip 23 is deformed, squeezing the limiting member 12 to move into the fixed cylinder 1, and at the same time the ejection spring 10 is retracted to realize the sliding positioning of the needle seat rod 11, thereby limiting the distance that the bloodletting needle 17 extends out of the positioning sleeve 3, and the needle head 17-2 is ejected to realize the puncture operation. The pressing sleeve 6 is released, the pressing spring 8 is retracted, and the pressing rod 4 moves upward, driving the needle seat rod 11 and the elastic strip 23 to move upward. When the limiting member 12 pops out of the fixed cylinder 1, it returns to its original state.
[0026] In the present invention, it is considered that after the movable cylinder 2 is adjusted in position, the movable cylinder 2 is locked to prevent the movable cylinder 2 from rotating. Therefore, a matching locking ring 24 is engaged with the threaded structure of the fixed cylinder 1, and the rotation direction is opposite to that of the threaded structure of the movable cylinder 2. The side surface of the locking ring 24 is an anti-slip structure.
[0027] In the present invention, it is taken into consideration that when the pressing sleeve 6 contacts the fixed tube 1, the elastic body can just compress the limiting member 12 into the fixed tube 1. Therefore, when the pressing spring 8 and the ejection spring 10 are in a free state, the distance from the inner bottom end of the pressing sleeve 6 to the upper end surface of the fixed tube 1 is the same as the distance from the lower end of the elastic strip 23 to the center of the limiting member 12.
[0028] Working principle and use method of the present invention:
[0029] Before bloodletting treatment, loosen the locking ring 24, unscrew the movable cylinder 2 from the fixed cylinder 1, select a suitable bloodletting needle 17, and insert it into the fixing hole 18 of the needle seat rod 11, fix it to the needle seat rod 11 with the bolt 20, and then screw the movable cylinder 2 onto the fixed cylinder 1, adjust the screwing amount of the movable tube onto the fixed tube as required, and screw the locking ring 24 to fit tightly with the movable cylinder 2. When bleeding, choose a suitable angle and determine the bleeding position through the positioning sleeve 3. After the positioning sleeve 3 fits against the patient's skin, press the pressing sleeve 6, and the pressing spring 8 and the ejection spring 10 are compressed at the same time. When the elastic strip 23 moves to the position of the limit piece 12, the elastic strip 23 is deformed, squeezing the limit piece 12 to move into the fixed tube 1. At the same time, the ejection spring 10 is extended and retracted, and the limit piece 12 fits with the limit ring 16 to achieve the sliding positioning of the needle seat rod 11, thereby limiting the distance that the bloodletting needle 17 extends out of the positioning sleeve 3, and the needle 17-2 is ejected to achieve the puncture operation. The bloodletting condition is observed according to the pressing sleeve 6. After the bloodletting is completed, release the pressing sleeve 6, the pressing spring 8 is elongated and deformed, and the pressing rod 4 moves upward, driving the needle seat rod 11 and the elastic strip 23 to move upward. When the limit piece 12 pops out of the fixed tube 1, it returns to its original state.
