Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Figure 1, the utility model includes nose small intestine tube body and seal wire 5.Nose small intestine tube body includes tube head 1, pipe
Body 3 and pipe inject interface 4, and tube head 1 and pipe injection interface 4 are respectively sleeved in the both ends of tube body 3.As shown in Fig. 2, tube head 1 is equipped with
Fluid hole 10, fluid hole 10 have it is multiple, and along the side wall ring of tube head 1 around.In order to avoid the blocking of fluid hole 10, on tube head
Multiple fluid holes 10 are set, guarantee that nutrient solution can smoothly flow into small intestine.Tube body 3 uses medical grade polyurethane material, service life
Long, submissive easy song, it is non-stimulated.
As depicted in figs. 1 and 2, it is cased at tube head 1 on 3 outer wall of tube body by spherical knot that is multiple continuous and being mutually communicated
The utricule 2 that structure is constituted, the directional spreding that chondritic extends along tube body 3.The quantity of chondritic is a in 3-5, ordinary circumstance
It is lower that the resistance that excessively will increase the push of nose small intestine tube body at 3 is set.It is spherical after injecting water or ultrasonic development liquid in utricule 2
The utricule 2 of structure is gradually expanded.Due to being outer wall that continuous chondritic is centered around tube body so that tube body front end it is mobile get up
Visibility improves under ultrasonic development, can thus judge the position after tube body enters small intestine well.And in ultrasonic guidance
It sets pipe and enters farther intestinal segment if necessary to conduit head end after the completion, utricule 2 can also be injected into liquid and entered more with small bowel peristalsis
Distal part position.
As shown in Fig. 2, including utricule phase circulation passage 30 and nutrient solution injection canal 31 inside tube body 3.Utricule phase circulation passage
30 are connected with utricule 2, and nutrient solution injection canal 31 is connected with tube head 1.Seal wire 5 is located in nutrient solution injection canal 31, leads
Silk 5 is bifilar helix type structure, is in strand cable shape, and helical structure compares existing linear type seal wire, is surpassed when setting pipe catheter propelling
Development is more clear under sound.The necessary long enough of the length of seal wire 5, to support tube body 3 to push forward.Seal wire 5 is completely into tube body 3
Afterwards, the end of seal wire 5 and tube head 1 are close, but to maintain a certain distance with fluid hole 10, to guarantee that seal wire 5 is located at tube body 3
It is interior, it is ensured that set pipe safety.
As shown in figure 3, pipe injection interface 4 includes first interface 40 and second interface 41, first interface 40 is communicated with utricule
Channel 30 is connected to, and second interface 41 is connected to nutrient solution injection canal 31.Injection can make the widened note of utricule 2 at first interface 40
Enter liquid, the nutrient solution that 41 injection patients need at second interface.Be connected with sprue 6 on pipe injection interface 4, the quantity of sprue 6 with
The sum of the quantity of first interface 40 and second interface 41 is consistent.After fluid injection, need to utilize sprue 6 by first interface 40
It is blocked with second interface 41, liquid reflux and bacterium is avoided to enter small intestine.
As shown in figure 4, the lateral wall of tube body 3 is equipped with extension 32,32 one end of extension connects with utricule phase circulation passage 30
Logical, the other end is adapted with first interface 40.In order to enable first interface 40 is adapted with utricule phase circulation passage 30, convenient for injection
The injection of liquid especially increases extension 32 in 3 outer wall of tube body, using the transition of extension 32, injection liquid is introduced utricule and is communicated
In channel 30, utricule 2 is finally entered, is realized to the full of utricule 2.
As shown in Figure 4, Figure 5, embodiment one, nutrient solution injection canal 31 are one, and second interface 41 is also one.Utricule
Phase circulation passage 30 is located in nutrient solution injection canal 31 and contacts with the fixation of the inner sidewall of nutrient solution injection canal 31, and utricule communicates
Channel 30 and nutrient solution injection canal 31 are mutually indepedent.This structure is suitable for injecting the patient of single kind nutrient solution.
As shown in Figure 6, Figure 7, embodiment two, nutrient solution injection canal 31 at least two, the quantity of second interface 41 with
The quantity of nutrient solution injection canal 31 is consistent.Mutual independence and it is fixed on 3 inner wall of tube body between nutrient solution injection canal 31, managed
The second interface 4 and nutrient solution injection canal 31 injected on interface 4 correspond.This structure is suitable for injecting a variety of type nutrition
The patient of liquid, different nutrient solutions are injected by corresponding nutrient solution injection canal 31, avoid mixing, blocking fluid hole 10.
The use principle of the utility model is: before the small intestinal tube of nose enters patient's antrum portion, utricule 2 is contraction, and
And seal wire 5 is in inside tube body 3, facilitates access for antrum portion.After the small intestinal tube of nose enters antrum portion, by first interface 40 toward utricule
Injection water or ultrasonic development liquid in phase circulation passage 30, so that utricule 2 expands, ultrasonic development is obvious.Then slow under ultrasound direct-view
Conduit is pushed forward, passes through antrum, pylorus, duodenal bulb, pars horizontalis duodeni；Since utricule 2 extends on tube body 3
Length it is longer, development is obvious, judge 1 location of tube head very well, and tube head 1 is promoted quickly to reach reasonable position, nose
After 1 position of sound production of tube head of small intestinal tube is correct, seal wire 5 can be withdrawn from, and using drawing liquid pump by utricule 2 water or ultrasound it is aobvious
Shadow liquid is taken away, and sprue 6 is finally blocked at first interface 40.Then it needs by patient, is infused by second interface 41 toward nutrient solution
Channel injection nutrient solution is penetrated, starts enteral nutrition and blocks sprue 6 at second interface 41 after nutrient solution is injected, prevent liquid
Body outflow.Since the small intestinal tube of nose is medical grade polyurethane, material is good, highly-safe, can more than 40 days of indwelling in vivo, even more
It is long, using the utility model may be implemented simplicity, safety, high success rate the small intestinal tube of ultrasonic guidance nose set pipe, fast implement
The conveying of nutrient solution.
