As shown in fig. 1 to 6, the internal medicine injection device of the present invention includes a body 2, a needle assembly 100, a medicine injection tube 7, an air moving tube 8, an air discharge tube 34, a color changing part 260, and a genuine product identification part 280.

The body 2 comprises: a head portion 22 formed with an insertion portion 26 opened to communicate with the outside; and a body 24 formed to be connected to the head 22 and formed in a tube shape having a cavity therein.

The body 2 is formed such that a main body 24 having a pipe shape has a predetermined length, and a head 22 is formed at an end of the main body 24, and the head 22 may be formed in a curved surface to be easily inserted into the inside of the vagina. One side of the head portion 22 is cut flat to open in an oval shape, thereby forming an insertion portion 26. Preferably, the body 2 is made of a material having high transparency, which is harmless to the human body, and which can have strong rigidity, and resins such as transparent Polycarbonate (PC), polymethyl methacrylate (PMMA), Polystyrene (PS), polypropylene (PP), and Polyethylene (PE) may be used. Most preferably of polycarbonate material.

The main body 2 is formed with an air discharge pipe coupling portion 3 formed on an outer surface and connected to the air moving pipe 8 inside, and an air discharge pipe 34 is connected to the air discharge pipe coupling portion 3.

The needle assembly 100 comprises a holding unit 4 and an injection member 6. The holding unit 4 may be inserted to be coupled to the head 22 of the body 2, or may be molded integrally with the head 22. The holding unit 4 is formed with a plurality of needle holders 42 having needle holes, and is formed with a pneumatic port 44 having a suction hole 440 at one side. Preferably, the holding unit 4 may be made of polypropylene or polyethylene, which is harmless to the human body.

The holding unit 4 includes: a holding unit body 40 having openings formed in the upper and lower portions thereof, respectively; and a plate 41 horizontally formed inside the holding unit body 40, and a plurality of needle holders 42 are formed on the plate 41. A hole is formed in each needle holder 42 so as to allow the needle 5 to penetrate therethrough.

Further, a guide 43 is formed around the lower opening of the holding unit body 40, and the guide 43 is in contact with the skin. Preferably, the guide 43 is formed to protrude from the insertion portion 26 of the head 22.

The medicine injection tube 7 is inserted into the body 2 and connected to the medicine injection port 62 of the needle assembly 100.

The air moving pipe 8 is connected to the air pressure port 44 to generate suction pressure.

On the other hand, as shown in fig. 7 to 9, according to another embodiment, the needle assembly 100 includes a holding unit 4 and an injection member 6, the holding unit 4 is formed with a plurality of needle holders 42 having needle holes, and an air pressure port 44 having a suction hole 440 is formed at one side.

The needle holder 42 is formed with a needle hole formed in a recessed manner so as to allow insertion and connection of a needle fixing portion 65 to be described later, and through which the needle 5 passes.

The injection member 6 includes an upper body 6a having a flow path 60 coupled to the holding unit 4 for injecting the drug solution, a drug injection port 62 communicating with the flow path 60, and a plurality of needles 5 communicating with the flow path 60 and penetrating the needle holder 42; and a lower body 6b coupled to the upper body 6a and having a needle fixing portion 65 through which the plurality of needles 5 penetrate. The needle fixing portion 65 is inserted into and coupled to the needle holder 42 to have a sealing force, and has a needle hole through which the needle 5 can penetrate.

The plurality of needles 5 may be arranged, and the number and arrangement of the needles may be arranged in a single row or in a zigzag pattern, or may be arranged in a plurality of rows side by side.

The plurality of needles 5 are arranged to extend inward by 0.1 to 2.5mm from the insertion portion 26 of the head portion 22, so that the needles 5 are not exposed with respect to the insertion portion 26. The length of the needle 5 may be formed to be 1.5 to 5.5mm so that at least 1.5mm and at most 5.5mm can be inserted into the skin of the operation site.

On the other hand, a guide 43 may be further formed at the lower opening portion of the holding unit 4, and the guide 43 may be formed to protrude from the insertion portion 26 of the head portion 22. The guide 43 is formed to protrude 0.1 to 2.5mm from the insertion portion 26 of the head 22.

The needle 5 is configured to extend inward from the guide 43, and the length of the needle 5 is 1.5-5.5 mm. When the exposed length of the syringe is less than 1.5mm, there is a fear that the effect of the operation is deteriorated in consideration of the skin thickness of the operation site; when the exposed length of the syringe exceeds 5.5mm, the effect of the operation may be deteriorated in consideration of excessive pain and the skin thickness of the operation site. More preferably, the length of the needle 5 is set to 2.0 to 3.0 mm.

Further, a guide 43 is formed around the lower opening portion, and the guide 43 is formed to protrude from the insertion portion 26 of the head portion 22. On the other hand, the height h of the guide 43 is preferably formed to protrude 0.5 to 2.5mm from the insertion portion 26 of the head 22. As the guide 43 presses the skin of the operation site, the skin is convexly introduced into the inside of the guide 43, or a vacuum is further formed on the inside of the guide 43 by the suction action, so that the skin is more strongly introduced into the inside of the guide 43 and the needle 5 is inserted into the skin. On the other hand, when the protruding length of the guide 43 is less than 0.5mm, there is a concern that the needle 5 scratches the skin even if the skin is slightly introduced into the inside of the guide 43 during the movement of the operation site. On the other hand, if the guide 43 is formed to protrude beyond 2.5mm, a strong suction pressure needs to be generated to be able to insert the needle 5 into the skin, and thus there is a concern that a pain may be caused. More preferably, the guide 43 is formed to protrude 0.7 to 1.2mm from the insertion portion 26 of the head 22. By forming the guide 43 so as to protrude, the guide 43 can be brought into contact with the skin before the head 22, and the skin can be confined in the lower space t of the holding unit body 40 when pressurized, so that a state of blocking the inflow of air can be maintained, and airtightness can be provided.

The holding unit 4 is made in an integral type integrally formed with the head portion 22 of the main body 2. Alternatively, the holding unit 4 may be configured as a separable type which is inserted into and coupled to the head 22 of the main body 2. Accordingly, the holding unit 4 can be mounted by being integrally formed with the insertion portion 26 of the head portion 22 of the main body 2 or by being inserted and coupled to the insertion portion 26.

On the one hand, the air moving pipe 8 is inserted into the body 2, and one end thereof is connected to the air pressure port 44 of the holding unit 4. The air pressure port 44 is formed closer to the lower portion than the plate member 41, that is, to the guide member 43, so that the lower space t of the internal space of the holding unit body 40 divided by the plate member 41 communicates with the air pressure port 44. The air moving tube 8 may be sequentially formed with a positive pressure and a negative pressure, for example, a negative pressure during the insertion of the needle into the operation site, and the vacuum may be released by the positive pressure after the injection of the drug.

The other end of the air moving duct 8 is connected to the air moving duct joint 3 provided in the main body 2. The air moving duct joint 3 includes an air outlet formed to protrude outside the main body 2 and an air inlet facing inside the main body 2, the other end of the air moving duct 8 is connected to the air inlet, and the air outlet duct 34 is connected to the air outlet.

On the other hand, the injection member 6 is coupled to the holding unit 4, has a plurality of needles 5 penetrating the needle holder 42, has a flow path 60 for injecting the drug solution into the plurality of needles 5, has a drug injection port 62 communicating with the flow path, and has a plurality of needles 5 communicating with the flow path 60.

One end of the drug injection tube 7 provided inside the main body 2 is connected to the drug injection port 62, and the other end of the drug injection tube 7 is connected to the syringe connection port 29 formed at the end of the main body 2. Thus, a syringe (not shown) is connected to the syringe connection port 29, so that the medicine can be continuously supplied.

On the other hand, the main body 24 of the main body 2 is formed with a confirmation mechanism capable of confirming one or more of the insertion depth and the rotation angle. The confirmation mechanism may be one or more selected from the group consisting of a scale, a division line, a number, a symbol, a character, a print, a sticker, a color, a protrusion, and a sign plate. For example, a plurality of dividing lines 27 may be formed at a predetermined pitch in the main body 24. The distance between the division lines 27 and the insertion depth corresponding to the number can be calculated from the degree of insertion of the division lines 27 into the operation site. Alternatively, the confirmation means may be constituted as a means that can be easily confirmed with the naked eye, such as a scale, a continuous number, a letter, a color, or the like, and the insertion depth may be visually recognized. However, the confirmation mechanism is not limited to the above-listed examples, but should be construed to include a mechanism capable of visually recognizing the degree of insertion.

A plurality of dividing lines 27, which enable the insertion depth to be confirmed, are formed in the main body 24 of the main body 2. The dividing line 27 may be formed by recessing a predetermined depth in the circumferential direction along the outer circumferential surface of the main body 24 or be convex in the circumferential direction. Further, a marking plate 200 on which an insertion depth scale 220 capable of confirming the insertion depth is marked is formed inside the main body of the main body 2. An angle measuring scale 240 may be further formed at the index plate 200 to enable measurement of an insertion rotation angle. Such an insertion depth scale 220 or an angle measurement scale 240 is formed of text or color so as to be able to improve visibility. Meanwhile, the insertion depth scale 220 or the angle measuring scale 240 may be formed by medical silicon ink, UV printing, and is not limited thereto.

As an example of the confirmation mechanism, as shown in fig. 1 and 2, 3 rows of dividing lines 27 are formed, and the dividing lines 27 are arranged at a pitch of 1 to 3 cm. Of course, this is just an example, and it is obvious that various modifications can be made to the pitch of the dividing lines 27.

On the other hand, the confirmation mechanism may include a color changing portion that changes color when reacting with the liquid. The color changing part 260 may be a color changing strip, which is different from the color before use and is changed to another color after contacting the body fluid of the human body during use. For example, a through hole 240 is formed in the main body 24 of the main body 2, and a color changing portion 260, which is formed so as to correspond to the through hole 240 and changes color when reacting with a liquid, is formed in the index plate 200. By visually checking whether or not the color changing portion 260 has changed color, it is possible to know whether or not the product is used, and reuse can be prevented. In addition to the confirmation of reuse, the main body 2 of the internal medicine injection device may further include a color changing portion 260' on the inner surface thereof in order to prevent reuse after sterilization after use of the internal medicine injection device. More preferably, the body 2 may further include a color-changing portion 260' on an inner side surface of the sign plate 200 so that whether the medicine injection device is washed or sterilized can be visually confirmed. On the other hand, a through hole corresponding to the color changing portion 260 'is formed, so that the disinfectant or the cleaning solution flows through the through hole to change the color of the color changing portion 260'. This prevents reuse after one use.

On the other hand, the main body may include a genuine product identification unit 280, and the genuine product identification unit 280 may include a short-range wireless communication unit to be able to communicate with an external control unit (not shown) to determine whether or not the genuine product is a genuine product. The Near Field Communication unit includes NFC (Near Field Communication) or RFID (Radio-Frequency Identification). The genuine product identification portion 280 is a confirmation mechanism of the body, and may be formed in the sign board 200. Whether the device is a genuine product or not can be determined by reading the ID assigned to each internal medicine injection device a, and when the genuine medicine injection device a is connected to the device, the control unit can recognize the genuine product and activate the device to enable the operation.

The operation of the present invention will be explained below.

Will the utility model discloses an interior income formula medicine injection device A connects in the controller that possesses suction generation portion and medicine injection portion.

The end part of the internal medicine injection device of the utility model is connected with the hose of the controller. The controller will be briefly described below. The controller is formed to include: a main board connected to the motor to provide an electric signal to control the injection of the medicine into the needle 5; an air hose connected to the needle assembly; a first suction pipe provided in the controller and connected to the air hose so as to communicate with the air hose; an air filter provided in the controller and filtering air sucked from the air hose; a suction pressure sensor formed on the main board and sensing a suction pressure of the connection port; a suction motor generating a suction pressure to suck air from the air filter; an electromagnetic valve that controls opening and closing; a microcomputer formed on the main board, which compares the suction pressure transmitted from the suction pressure sensor with the injection amount to sense the skin insertion of the needle 5, and controls the operation amount of the motor of the injector to set the injection amount of the medicine of the injector injected through the needle 5; a power switch for controlling the opening and closing of the injection device; and a power supply section that supplies power to the injection device.

The head 22 of the body 2 of the internal medicine injection device of the present invention is inserted into the vagina, and after the head is inserted to an appropriate depth with the dividing line 27 as a reference, the injection member 6 is adjusted to face the site to be operated.

Then, the air moving tube 8 generates suction pressure, so that the skin is sucked into the lower space t of the holding unit body 40 and the inside of the guide 43, and the tip of the introducing needle 5 is introduced into the skin. Thereafter, the drug is injected into the skin through the needle 5. Since the skin is punctured with the needle 5 during the injection of the medicine to introduce the medicine into the skin, there is a possibility that bleeding or other body fluids may come out, but this may be sucked into the air pressure port 44, the air moving tube 8, and the air discharge tube and discharged to the outside. When the drug injection is completed, the suction pressure is released, and the internal drug injection device a is moved to another site to be operated, and then the drug injection operation is repeated.
