Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
embodiment 1, as shown in Figure 1, give the structural representation of the first embodiment of spininess hair style of the present utility model absorption entry needle, it is made up of body 1, sealing plate 2, limiting plate 3, multiple entry needle 4; Fig. 2, Fig. 3 and Fig. 4 sets forth the front view of body, rearview and right view, Fig. 5 gives the sectional view in A-A cross section in Fig. 2, Fig. 6, Fig. 7 and Fig. 8 sets forth sealing plate front view, rearview and left view, Fig. 9 and Figure 10 sets forth front view and the left view of limiting plate.
The both ends open of shown body 1, central authorities are dividing plate 5, and the both sides of dividing plate 5 are formed respectively inhales negative pressure cavity 7 and injecting cavity 8, and multiple entry needle 4 is evenly fixed on dividing plate 5, and entry needle 4 stretches to be inhaled in negative pressure cavity 7.Body 1 offers and the air entry 6 inhaled negative pressure cavity 7 and communicate, air entry 6 is connected with suction negative pressure device, and can make to be in negative pressure state in suction negative pressure cavity 7, entry needle 4, for stretching in the subcutaneous shallow layer tissue of patient, realizes the safety injection of medicine.
Shown sealing plate 2 is arranged in injecting cavity 8, and the inwall of the surrounding of sealing plate 2 and injecting cavity 8 is in sealing state.Medicament lumen 9 is formed between sealing plate 2 and dividing plate, sealing plate 2 is provided with the drug-feeding tube 13 that medicament lumen 9 is communicated with the external world, each entry needle 4 on dividing plate 5 is all communicated with medicament lumen 9 by corresponding injection orifice 11, so that the medicine flowed into from drug-feeding tube 13 is injected into the affected area of patient successively through medicament lumen 9, injection orifice 11, entry needle 4, realize safety of medicine treatment.
Stretching to the degree of depth of the subcutaneous shallow layer tissue of patient in order to control entry needle 4, being also provided with limiting plate 3 in shown suction negative pressure cavity 7, limiting plate 3 place plane and entry needle 4 place straight line are in mutual plumbness.Limiting plate 3 is provided with the pin hole 10 matched with entry needle 4, the diameter of pin hole 10 is greater than the diameter dimension of entry needle 4, entry needle 4 runs through and later from pin hole 10, certain gap is also left, the position, front end of limiting plate 3 can be made also negative pressure can be produced by air entry 6 between entry needle 4 and pin hole 10.
Under suction function, patient's affected area towards suction negative pressure cavity 7 medial movement, and is injected the outside moving to limiting plate 3 after pin 4 thrusts, and by the position-limiting action of limiting plate 3, controls the degree of depth that entry needle 4 thrusts patient's affected area.Inhale negative pressure cavity 7 coniform for what increased gradually by introversive outer diameter dimension, the outer surface of limiting plate 3 is the taper surface matched with the inner surface inhaling negative pressure cavity 7; By selecting the limiting plate 3 of different-diameter size to match with suction negative pressure cavity 7, the distance at distance entry needle 4 top, limiting plate 3 outer face can be changed, and then change the degree of depth that entry needle 4 thrusts the subcutaneous shallow layer tissue of patient, realize the treatment to various disease.
Evenly flow out from multiple entry needle 4 to make the medicine of injection, as shown in Figure 3, dividing plate 5 is provided with medicine guiding gutter 12 on the side of medicament lumen 9, adjacent injection orifice 11 is all connected by medicine guiding gutter 12, the medicine flowed out from drug-feeding tube 13 like this can by medicine guiding gutter 12 evenly, flow rapidly into in each injection orifice 11, realize the even injection of medicine.
For the ease of being connected with syringe, shown drug-feeding tube 13 is connected with syringe adapter 14.Shown injecting cavity 8 and the shape of medicament lumen 9 can for circular, oval, polygon or other be suitable for the shape that matches with patient's affected area.
embodiment 2as shown in figure 11, give the structural representation of the second embodiment of spininess hair style of the present utility model absorption entry needle, Figure 12 and Figure 13 sets forth front view, the rearview of body 1 in the present embodiment, Figure 14 gives the sectional view in B-B cross section in Figure 12, Figure 15 gives the structural representation of limiting plate 3 in the present embodiment, and Figure 16 gives the structural representation of sealing plate 2 in the present embodiment.
In order to avoid the medicine flowed out from drug-feeding tube 13 directly penetrates from entry needle 4, when entry needle 4 adopts two or more, should ensure that the outlet of drug-feeding tube 13 is all not relative with injection orifices 11 all on dividing plate 5, to ensure the even injection of medicine further.
Except the quantity of pin hole 10 on the quantity of entry needle 4, limiting plate 3 is with except identical in embodiment 1 in the present embodiment, remaining structure is all identical; In embodiment 1, on entry needle 4 and limiting plate 3, the quantity of pin hole 10 is 19, and in embodiment 2, on entry needle 4 and limiting plate 3, the quantity of pin hole 10 is 4.On entry needle 4 and limiting plate 3, the distribution form of pin hole 10 and quantity also can be chosen according to the actual requirements.
embodiment 3as shown in figure 17, give the structural representation of the third embodiment of spininess hair style of the present utility model absorption entry needle, it offers except a pin hole 10 except dividing plate 5 being provided with on an entry needle 4, limiting plate 3, identical all with embodiment 1 of remaining structure.Owing to adopting an entry needle 4, the injection orifice 11 on the outlet of drug-feeding tube 13 and dividing plate 5 to it, to realize the smooth injection of medicine.The absorption entry needle of the present embodiment, owing to adopting an entry needle 4, is suitable for the safe administration treatment of small size focus.
The use procedure of spininess hair style absorption entry needle of the present utility model is as follows:
First in entry needle 4, inject liquid medicine through syringe adapter 14, the air in drug-feeding tube 13, medicament lumen 9 and entry needle 4 is all discharged; Then by air entry 6 with take out negative pressure device and be connected, and the opening plaster inhaling negative pressure cavity 7 is invested on the position to be treated (during as treated the bromhidrosis of patient, the opening inhaling negative pressure cavity 7 aims at the transaxillary position of patient) of patient; Start and take out negative pressure device, under suction function, the skin of patient can move towards limiting plate 3, and is injected pin 4 and pierces through, and due to the position-limiting action of limiting plate 3, the degree of depth making each entry needle 4 deep is all equal; Injectable drug while negative pressure is inhaled in maintenance, namely achieves the safety of medicine treatment of the large area of affected area, constant depth.
