Postoperative minimally invasive subcutaneous continuous drainage device
The utility model relates to medical instrument technical field in general, and more particularly to a kind of postoperative minimally invasive subcutaneous continuous drainage device, including puncture needle, drainage sheath, three-way valve, drainage tube and negative pressure drainage bottle, three-way valve includes first port, second port and third port, first port and second port coaxial arrangement, drainage sheath is connected with first port, puncture needle is inserted by second port and passes out from drainage sheath, negative pressure drainage bottle is connected with third port by drainage tube.The application is pierced by puncture needle, so that drainage sheath enters the wound part in body together, after reaching the wound part, the puncture needle is extracted from second port, since the puncture needle fills the drainage sheath when puncturing, the tissue debris can be avoided to block the drainage sheath, after extracting the puncture needle and leaving the drainage sheath, the drainage sheath can establish good suction passage, and simultaneously switch three-way valve, so that pus and blood water directly enter negative pressure drainage bottle along drainage tube from third port, avoid the leakage of drainage fluid caused by complicated disassembly and assembly.

ActiveCN121949934Aavoid defectscompact structurePharmaceutical containersMedical packagingPolymer scienceVulcanization
The invention relates to a low-ash rubber-plastic blending medical rubber plug and a preparation method thereof, and belongs to the technical field of medical packaging rubber. The formula of the rubber plug comprises the following components in parts by weight: chlorinated butyl rubber, modified styrene-ethylene / butylene-styrene block copolymer powder, calcined kaolin, precipitated hydrated silicon dioxide, titanium dioxide, carbon black, alkylphenol disulfide and zinc oxide. The preparation method comprises the following steps: firstly, carrying out surface modification on styrene-ethylene / butylene-styrene block copolymer powder and alkyl phosphonium laurate to obtain modified powder; and processing the chlorinated butyl rubber, the modified powder, the filler and the auxiliary agent into the rubber plug through processes of banburying, open milling, vulcanization molding and the like. Through a rubber and plastic blending structure of the modified SEBS powder, high hardness (Shore A hardness is greater than or equal to 48) is realized while low ash content (less than or equal to 15%) is ensured, the adhesion problem caused by insufficient hardness of a traditional low-ash rubber plug is effectively solved, puncture falling scraps are remarkably reduced, and the rubber plug is suitable for packaging high-standard medicines such as biological agents.

Multifunctional coffee funnel
PendingCN121943097AEasy to installSimple and fast operationBeverage vesselsStructural engineeringMechanical engineering
The invention discloses a multifunctional coffee funnel which comprises a funnel upper shell and is characterized in that the multifunctional coffee funnel further comprises a funnel base and a capsule mounting module, the funnel base is provided with a containing cavity and a liquid outlet communicated with the containing cavity, the capsule mounting module comprises a plurality of capsule adapting bases matched with different coffee capsules, the capsule adapting bases are arranged on the containing cavity, and the liquid outlet is communicated with the containing cavity. The funnel base is detachably connected to the lower portion of the funnel upper shell, and the funnel upper shell is further provided with an elastic puncturing piece used for puncturing the coffee capsule and achieving fluid guiding. According to the multifunctional coffee funnel, by additionally arranging the capsule mounting module comprising different capsule adapting seats, when different coffee capsules need to be adapted, only the funnel base needs to be detached, then the capsule adapting seats are replaced, and then the capsule adapting seats are remounted, that is, different funnel upper shells and funnel bases do not need to be replaced, so that the overall manufacturing cost of the product is reduced, and the universality is wide; and the size of the capsule adapter seat is relatively small, so that the overall packaging and transportation cost of the product can be reduced.

A soluble microneedle patch for drug enrichment at the needle tip and its preparation method
ActiveCN116747186BHigh biosecurityGood puncture effectMicroneedlesMedical devicesPharmacy medicineOrganosolv
This invention discloses a soluble microneedle patch with drug-enriched needle tip and its preparation method, belonging to the field of microneedle technology. The preparation method includes: (1) preparing a drug-loaded solution using a hydrophilic drug and a soluble polymer as solutes, injecting the drug-loaded solution into the needle body part of a microneedle mold, and performing low-temperature centrifugal drying; (2) preparing a polymer solution using a soluble polymer as a solute, injecting the polymer solution into the remaining part of the microneedle mold, centrifuging and drying, and then demolding to obtain the soluble microneedle patch with drug-enriched needle tip. Compared with the conventional natural drying molding method, the two-step centrifugal drying method of this invention can enrich the drug at the tip of the microneedle, thereby enabling rapid release of the drug from the microneedle, improving drug utilization, and reducing waste caused by the inability of the soluble microneedle body to fully enter the skin. At the same time, the microneedles prepared using a soluble matrix avoid organic solvent residue, have good biocompatibility, and good puncture effect.
