The invention is further described below with reference to the following figures and specific examples.
The acupuncture point needle embedding compound device for preventing and treating vomit shown in fig. 1-2 comprises a needle pressing body consisting of a needle head 1 and a substrate 2, wherein the needle head 1 is a hollow needle, a medicine carrying cavity 21 communicated with the hollow needle is arranged in the substrate 2, and a thermal expansion block 3 is fixed beside the medicine carrying cavity 21; the thermal expansion block 3 and the medicine carrying cavity 21 are separated by an isolation film 22 in the form of a permeable polymer film.
The back of the substrate 2 is provided with the needle head 1 and is lined with an adhesive layer for fixing the skin, and the front of the substrate 2 is the side without the needle head. The front surface of the substrate 2 is also attached with a silvered infrared reflecting layer 4 for reflecting human body heat.
The thermal expansion block 3 is a paraffin wax type solid-liquid phase change material with small volume change during phase change. The thermal expansion block 3 is fixed on one side of the medicine carrying cavity 21 facing the front surface of the substrate. The front surface of the substrate 2 is provided with mastoid-shaped protrusions 23, and the thermal expansion block 3 is accommodated in the mastoid-shaped protrusions 23. The drug-loading cavity 21 is in a circular truncated cone shape, the small end of the circular truncated cone shape is communicated with the hollow needle, and the large end of the circular truncated cone shape is attached and propped against the thermal expansion block 3.
The passage of the hollow needle is a capillary pipeline with the diameter equal to 0.3 mm. The quantity of the pinheads 1 is three, the pinheads 1 are arranged in a shape like a Chinese character 'pin' in the center of the back of the substrate 2, and the pinheads 1 are vertically fixed on the substrate 2.
The operation principle of this embodiment will be explained more specifically: the mastoid 23 contains solid-liquid phase-change material, which is separated from the drug-carrying cavity 21 corresponding to the tail end of each hollow needle in the substrate 2 by a water-permeable separation membrane 22. The drug-loading cavity 21 is separated from the thermal expansion block 3 by an isolating film 22 and is communicated with a capillary pipeline in the hollow needle. When the thumb needle is applied to a human body, the infrared reflecting layer 4 on the upper part of the mastoid-shaped protrusion 23 reflects heat dissipated by the skin, a part of the heat is gathered in the mastoid-shaped protrusion 23 and is heated to be expanded when meeting heat, meanwhile, after the thumb needle enters subcutaneous tissues, because the diameter of a capillary pipeline is small, interstitial fluid is upwards introduced into the drug carrying cavity 21 through the siphonage effect, and further enters the space where the phase change material is located through the isolation film 22, the volume expansion of the phase change material is accelerated, and because the mastoid-shaped protrusion 23 at the rear end of the expansion part pushes the isolation film 22 downwards to move, so that the drug liquid contained in the drug carrying cavity 21 is extruded to downwards and enters the subcutaneous tissues through the capillary in the hollow needle, and the pre-placing and treating effects are exerted.
In use, the front end of the hollow needle of the pressing needle can be inserted into the prefabricated concentrated and purified ointment to carry medicine in advance, and then the hollow needle penetrates into a human body, on one hand, the electrochemical action of the metal needle head can be utilized to stimulate acupuncture points, and on the other hand, the purified ointment brought by the hollow needle can break through the physical barrier of the epidermis to act on subcutaneous tissues (the medicine can be carried in advance, namely, no medicine is inserted into the hollow needle into the skin).
Along with the absorption of related medicines, liquid between subcutaneous tissues upwards moistens the medicine carrying cavity 21 along the hollow needle through the capillary siphoning effect, meanwhile, the infrared reflecting layer 4 at the top reflects one part of heat generated by local skin back to the subcutaneous tissues to promote local blood circulation and medicine absorption, the other part is continuously accumulated on the action part to trigger the phase change substance contained in the pressing needle substrate 2 to generate phase change and volume expansion, and the long-acting medicines in the medicine carrying cavity 21 are pushed downwards to enter the subcutaneous tissues through the hollow needle to continuously play related roles.
In order to prevent emesis, the related medicines can be selected from aromatic resuscitation inducing traditional Chinese medicines such as Moschus, saviae Miltiorrhizae radix, borneolum, etc., in order to maintain long-term medicinal effects, the second half of the medicine carrying cavity 21 can be provided with extract or concentrated extract containing Ginseng nourishing medicines, so as to provide related energy support for stable operation of human body internal circulation after inducing resuscitation and dredging channels and collaterals.
The packaging plate of the combined acupuncture point-burial needle device for preventing and treating vomiting shown in fig. 3 to 5 comprises the combined acupuncture point-burial needle device for preventing and treating vomiting and a plate body 5 with a pit 51, wherein the edge of a substrate 2 of the combined acupuncture point-burial needle device for preventing and treating vomiting is connected to the inner edge of the hole of the pit 51 through a solid-hole alternate breaking structure 6. The structure 6 will break solid areas therein when subjected to shear pressure (e.g., pressing the substrate 2 against the plate 5), thereby creating cracks along the structure 6 when desired. The specific bursting structure 6 adopts an easy-tearing line form, namely, the connection with the peripheral plate body 5 is realized through a laser drilling technology. The needle 1 is directed into the recess 51. The uppermost layer of the front surface of the substrate 2 is attached with a patch 7 with a raised edge, and the patch 7 covers and is larger than the front surface of the substrate 2.
The operation principle of the packaging board of this embodiment will be explained more specifically: the concave pit 51 forms an outer protective cover for the needle head 1, an isolation space is formed between the concave pit and the plate body 5, the needle head 1 is in a clean state before being unsealed, and the easy-to-tear line between the thumb-tack needle and the square plate body 5 is discontinuously and uniformly distributed on two circles of the periphery of the substrate 2. The substrate 2 is pressed downwards to cause the easy-to-tear line to be broken, the substrate 2 is separated from the plate body 5 along the easy-to-tear line at the periphery,
as shown in fig. 5, pressing down causes the snap fastener to separate from the snap-broken structure 6 on the board body 5; the thumb-tack needle falls into the concave pit 51; the user can pick up the raised part with his or her fingers and take it out of the recess 51, so that the subsequent operation can be performed.
The effect produced by this embodiment is: the press needle is improved to load related medicines, the medicines are remained at local parts to play a continuous role after the press needle is penetrated into a dermal layer of skin to stimulate acupuncture points, and the related loaded medicines can be sequentially administered in vivo by selecting different medicine formulas according to needs. For example, initially, the absorption of the drugs is further promoted on the basis of acupuncture through the resuscitation effect of the aromatic warming and activating drugs, and on the other hand, the vomiting symptom of the patient is controlled and relieved, and as the efficacy of the drugs subsides, the overall endurance level of the patient is improved through the warming and invigorating effects of the subsequent drugs.
While the preferred embodiments of the present invention have been illustrated and described, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
