Example 1
Referring to fig. 1-3, the present embodiment provides a drug delivery device for gastrointestinal disease treatment, including a fluid delivery hose 2, a spreading portion 3 movably disposed on the fluid delivery hose 2, and a drug delivery portion 4 disposed at a lower portion of the fluid delivery hose 2, wherein the upper portion of the fluid delivery hose 2 is provided with a balloon 1, specifically, the drug delivery portion 4 includes a plurality of annular protrusions 10 disposed on a side wall of the fluid delivery hose 2 and a plurality of liquid outlet holes 11 disposed on a side wall of the fluid delivery hose 2, the annular protrusions 10 and the liquid outlet holes 11 are alternately distributed, the bottom of the fluid delivery hose 2 is provided with an inwardly recessed conical flow guide portion 13, a liquid storage bend 12 is formed between the conical flow guide portion 13 and the fluid delivery hose 2, and the conical flow guide portion 13 is provided with a bottom hole 14 for discharging a liquid medicine in the liquid storage bend 12; the opening part 3 comprises an opening cylinder 6 movably sleeved on the infusion hose 2.
When the medical balloon is used, one end of the infusion hose 2 with the administration part 4 extends into an intestinal tract from the mouth of a patient, the medical fluid is injected into the infusion hose 2 from the upper end of the infusion hose 2 through the medical fluid, the medical fluid flows to the administration part 4 through the balloon 1, and the medical fluid in the administration part 4 acts on a fester part in the intestinal tract along the liquid outlet 11 under the extrusion of the balloon 1 by pressing the balloon 1, so that administration operation is realized; through the alternate distribution of the annular bulges 10 and the liquid outlet holes 11, the inner wall of the intestinal tract of the patient can be supported by the annular bulges 10, so that the phenomenon that the inner wall of the intestinal tract of the patient blocks the liquid outlet holes 11 to influence the normal outflow of the liquid medicine is avoided; by arranging the opening cylinder 6, the mouth of the patient can be occluded on the opening cylinder 6, so that discomfort caused when the infusion hose 2 of the patient extends into the intestinal tract is avoided, the mouth is automatically closed, and medicine feeding is affected; through the setting of toper water conservancy diversion portion 13, can be with the remaining liquid medicine water conservancy diversion of the inside of portion of dosing 4 to the curved 12 department of depositing liquid, discharge by bottom outlet 14 again to flow to the intestinal inner wall by the inclined plane of toper water conservancy diversion portion 13 bottom, thereby avoided the liquid medicine to have too much to remain in infusion hose 2 inside, avoided the waste of liquid medicine.
Further, the one end of propping open a section of thick bamboo 6 and keeping away from portion 4 of dosing is fixed and is provided with side shield 5, the area of side shield 5 is greater than prop open a section of thick bamboo 6's sectional area, through the setting of side shield 5 for the disease is when stinging opening a section of thick bamboo 6, utilizes side shield 5 to support outside the disease mouth, thereby avoids the disease to prop open a section of thick bamboo 6 with whole and swallow in the mouth.
Further, the outer wall of the opening cylinder 6 is provided with an occlusion groove 7, and through the arrangement of the occlusion groove 7, the patient can occlude the upper tooth part and the lower tooth part into the occlusion groove 7, so that the stability of the opening cylinder 6 and the mouth of the patient is improved, and the opening cylinder 6 is prevented from being separated from the mouth of the patient.
Further, prop and open a section of thick bamboo 6 inboard and be provided with interior fagging 8, through the setting of interior fagging 8, can improve the intensity that props a section of thick bamboo 6 to prevent that the occlusal force of disease is too big, causes the extrusion to infusion hose 2, influences the normal circulation of liquid medicine.
Furthermore, through holes matched with the infusion hose 2 are formed in the inner supporting plate 8 and the side baffle 5.
Furthermore, the opening cylinder 6 is in a cylindrical or elliptic cylindrical structure, so that the opening cylinder is matched with the mouth shape of the mouth of a human body when the mouth is opened, and the pain of the patient in medicine application is relieved.
The working principle of the embodiment is as follows: when the medical balloon is used, one end of the infusion hose 2 with the administration part 4 extends into the intestinal tract from the mouth of a patient, then the medical fluid is injected into the infusion hose 2 from the upper end of the infusion hose 2 through the medical fluid, and the medical fluid flows to the administration part 4 through the balloon 1 and acts on the fester inside the intestinal tract along the liquid outlet 11, so that administration operation is realized; through the alternate distribution of the annular bulges 10 and the liquid outlet holes 11, the inner wall of the intestinal tract of the patient can be supported by the annular bulges 10, so that the phenomenon that the inner wall of the intestinal tract of the patient blocks the liquid outlet holes 11 to influence the normal outflow of the liquid medicine is avoided; by arranging the opening cylinder 6, the mouth of the patient can be occluded on the opening cylinder 6, so that discomfort caused when the infusion hose 2 of the patient extends into the intestinal tract is avoided, the mouth is automatically closed, and medicine feeding is affected; through the setting of toper water conservancy diversion portion 13, can be with the remaining liquid medicine water conservancy diversion of the inside of portion of dosing 4 to the curved 12 department of depositing liquid, discharge by bottom outlet 14 again to flow to the intestinal inner wall by the inclined plane of toper water conservancy diversion portion 13 bottom, thereby avoided the liquid medicine to have too much to remain in infusion hose 2 inside, avoided the waste of liquid medicine.
Example 2
Referring to fig. 4, compared with embodiment 1, in the present embodiment, a supporting portion 15 capable of promoting the balloon 1 to rebound quickly is further disposed inside the balloon 1, and the supporting portion 15 enables the balloon 1 to recover quickly after being deflated, so as to perform the next pressing operation quickly.
Specifically, the supporting portion 15 includes a plurality of supporting ribs, and a plurality of supporting ribs one end is connected as an organic whole, the other end all downwardly extending and with 1 inner wall fixed connection of sacculus.
When pressing sacculus 1, the support muscle piece receives the extrusion, loosens sacculus 1 back, orders about sacculus 1 under the effect of support muscle piece self toughness and kick-backs fast for the reconversion that sacculus 1 can be quick.
The embodiment of the invention has the advantages of simple structure, convenient use and good medicine feeding effect, and the patient can bite the mouth on the opening cylinder 6 by the arrangement of the opening cylinder 6, thereby avoiding the discomfort caused when the transfusion hose 2 extends into the intestinal tract of the patient, causing the automatic closing of the mouth and influencing the medicine feeding; through the setting of toper water conservancy diversion portion 13, can be with the remaining liquid medicine water conservancy diversion of the inside of portion of dosing 4 to the curved 12 department of depositing liquid, discharge by bottom outlet 14 again to flow to the intestinal inner wall by the inclined plane of toper water conservancy diversion portion 13 bottom, thereby avoided the liquid medicine to have too much to remain in infusion hose 2 inside, avoided the waste of liquid medicine.
Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
